- Abstract
Background: The impact of a sedentary and unhealthy lifestyle on cardiovascular health is well-documented, however the current obesity and hypertension trends among children is concerning. The ExAMIN Youth SA study aims to investigate the impact of lifestyle behaviors (physical fitness/activity, dietary intake and psychosocial factors) involved in early vascular aging among South African children. Methods: This study is an analytical, multidisciplinary, observational cohort study in a school-based setting. We aim to phenotype a cohort of ∼1,000 primary school children (black and white boys and girls between ages 5–9 years) based on current clinical childhood conditions including hypertension and obesity. The primary phenotype is large artery stiffness and retinal microvascular diameters, both biomarkers of early vascular aging. The risk factors and mediators of early vascular aging and also responsible for the clinical conditions include physical inactivity, unhealthy diet, and life stress. Additionally, urinalysis and salivary analyses will be performed to identify biomarkers related to the pathophysiology of early vascular aging. Discussion: In line with the growing prevalence of obesity and hypertension responsible for the development of early vascular aging from childhood to adulthood, this study will address the critical areas in which we observe unfavorable arterial modulation related to dietary behaviors, physical inactivity, and early life stress. Implementation of novel biological markers may further contribute to our understanding of early cardiovascular adaptations in childhood, and aid in the development of primary prevention programs

Research has suggested that coping under pressure could be rooted in the ability to identify and manage one's emotions. In this study, we investigated this hypothesis using cross-sectional data obtained from a sample of South African national and university level female field-hockey players (N = 60, Mage = 21.57, SD = 3.65). A correlational research design was adopted of which a pen-and-paper survey containing the Emotional Intelligence Scale and Athletic Coping Skills Inventory-28 was used to collect the data. Descriptive results exposed players to yield higher than average levels of total emotional intelligence and coping ability in sport with significant differences noted between the national and university level players in terms of their ability to manage their own emotions (p = 0.018), utilise emotions (p = 0.007, d = 0.74), coping with adversity (p = 0.002, d = 0.84), coachability (p < 0.01, d = 3.17), and overall coping ability (p < 0.01, d = 1.00). After controlling for the level of participation, hierarchical linear regression analyses confirmed the relationship between the study variables exposing total emotional intelligence to be a significant predictor of players' ability to cope with adversity (β = 0.55, p = 0.006), concentrate (β = 0.43, p = 0.044), maintain confidence and achievement motivation (β = 0.42, p = 0.027), as well as overall coping ability (β = 0.28, p = 0.023). It was concluded that emotional intelligence may be a worthy contributor in the psychological profiling of players and a plausible intervention mapping tool in sport psychology practice to potentially enhance the coping ability of female field-hockey players.

- Abstract
The primary aim of this study was to explore gender differences regarding the sport psychological skills (SPS) profile of adolescent sport participants in a South African context. The present study forms part of an extensive five-year longitudinal study, the Physical Activity and Health Longitudinal Study (PAHL-Study). A crosssectional research design was used to gather quantitative data. Two hundred and eleven (89 boys and 122 girls) grade nine pupils (14 and 15 years of age) participated in the study. The participants completed the Athletic Coping Skills Inventory for Sport (ACSI-28) to determine their SPS profile. The results showed that the boys obtained higher mean scores in seven of the eight measured sport psychological skills. Freedom from worry was the only skill that yielded a statistically significant difference, with the boys (52.06±20.27) obtaining a higher mean value than the girls (46.17±20.56). In conclusion, the current findings indicated that, at this developmental level of competitive sport, boys and girls participants seem to be very similar regarding their sport psychological skills dispositions

Cognition ,Emotional intelligence ,Rugby union ,Performance ,Sport psychology ,Personality - Abstract
PhD (Health Science), North-West University, Potchefstroom Campus At the elite level in sport, the difference between winning and losing is often ascribed to a player’s level of psychological abilities. Given that athletes’ physical, tactical and technical abilities are fairly equal, an athlete’s winning performance usually is ascribed to him/her possessing better mental skills than the rest. In rugby, numerous studies have investigated certain aspects important for performance such as anthropometrical, physiological and biomechanical requirements. However, the psychological characteristics of elite rugby players and the relationship thereof with performance have not yet attracted much attention among researchers. Based on the limited research pertaining to the role of cognition, personality and emotional intelligence with regard to playing level in rugby, the following research questions were formulated: 1) Which neurocognitive variables significantly differ between male, South African professional and semi-professional rugby union players? (Article 1); 2) Which personality traits significantly differ between male, South African professional and semi-professional rugby union players? (Article 2); 3) Which aspects of emotional intelligence significantly differ between male, South African professional and semi-professional rugby union players? (Article 3); and 4) Does a significant interrelationship exist between neurocognitive variables and emotional intelligence and between personality and emotional intelligence among male, South African professional and semi-professional rugby union players? (Article 4). The objectives of the study were subsequently also formulated as follows: 1) To determine if neurocognitive variables significantly differ between male, South African professional and semi-professional rugby union players; 2) To determine whether personality traits significantly differ between male, South African professional and semi-professional rugby union players; 3) To determine whether aspects of emotional intelligence significantly differ between male, South African professional and semi-professional rugby union players; and 4) To establish whether a significant interrelationship exists between neurocognitive variables and emotional intelligence and between personality and emotional intelligence among male, South African professional and semi-professional rugby union players. Since this was an exploratory study, a quantitative empirical research approach with a cross-sectional survey design was used along with a convenience sample. The sample consisted of 79 male South African rugby union players between 19 and 37 years of age participating at national, transnational and university levels. To address objectives 1-3, the total group of players was divided into a professional group (n = 55) and a semi-professional group (n = 24). The professional group consisted of full-time players who were competing at the highest level in a transnational competition and were remunerated for playing rugby, while the semi-professional players were full-time students at a university and competing in the top tier university competition, but therefore not earning a salary for being part of the team. To address objective 4, all the players were treated as one group. The players all completed the WebNeuro Sport online assessment representing a holistic assessment of various factors which might potentially influence an athlete’s performance. The assessment consists of a demographic questionnaire (including name, surname, age and gender) and seven assessments, namely the Carlstedt Subliminal Attention, Reactivity and Coping Scale-Athlete Version (CSARCS-A); the cognitive functioning domain; the Brain Resource Inventory for Screening Cases (BRISC) which is a screening tool for markers of self-regulation; the Depression Anxiety Stress Scale (DASS); a sleep assessment questionnaire which evaluates the test taker’s quality and frequency of sleep; the Brain Resource Inventory for Emotional Intelligence Factors (BRIEF) and a Personality inventory (NEO-FFI). For this study, only the data of the cognitive functioning domain, the BRIEF, and the NEO-FFI were used. The results of the quantitative data suggest that no significant neurocognitive difference existed between the professional and semi-professional players. Neuroticism was, however, the only personality trait that was found to differ significantly between players playing at different levels. On emotional intelligence (EI), the external emotional capacity subscale (EEC) obtained a medium worthwhile effect in favour of the professional players. Lastly, the findings indicate a significant correlation between total EI and extraversion, and conscientiousness. Internal emotional capacity (IEC) significantly correlated with extraversion, openness, agreeableness and conscientiousness. External emotional capacity (EEC) showed a significant correlation with extraversion and openness. With regard to cognition, external emotional capacity significantly correlated with verbal ability. Contrary to our expectations, the findings showed few psychological differences between professional and semi-professional players with only neuroticism and external emotional capacity differing between players playing at different levels. Finally, seen from a theoretical point of view, the results indicated that EI is rather associated with personality than with an individual’s cognition. Doctoral

Expert performance in sport depends on physiological, technical, emotional, and cognitive domains. The aim of this study was to determine the relationship between the measures of cognition (memory capacity, attention and behavioural tasks, sensory-motor functioning, verbal tasks, executive functioning and emotion identification) and on-field performance [as determined by the key performance indicators (KPIs)] of university-level rugby players. A group of 25 male university-level rugby players were recruited from a South African University’s Rugby Institute squad who participated in the Varsity Cup Tournament (VCT). The players’ cognitive functioning was measured using the WebNeuro Sport, developed by the BRC, which consists of seven measuring scales. The cognition scale was used for further analysis. To quantify the players’ on-field performance, the KPIs of each player were determined for each game by using the technical analysis software, Stratus. Results indicated that the tight five forwards’ sensorymotor ability might contribute to the number of carries the players perform during attacking play. The loose forwards’ showed a positive correlation between total contribution and emotion identification. For the backs, medium to strong positive correlations exit between emotion identification and total attacking contribution, passes as well as kicks. Therefore, effective pattern recognition ability and associated quick decision-making might be important cognitive functions for backline players as well as loose forwards.Keywords: Cognitive functioning, neuropsychology, performance, performance indicators, Rugby union, sport psychology

- Abstract
Introduction: Puberty signifies developmental changes that differs in timing and tempo which contributes to noteworthy changes in stature, body composition, and the neuroendocrine axis. These changes, once again, directly influences the physical and motor abilities of girls, and consequently their performance in sport. Methods: This longitudinal study included a convenience sample where girls (n=58) aged 13.51+3.51 were divided by means of the Status Quo method, into a pre-(n=13) and post-menarche (n=45) group according to their menarche status. Anthropometric variables were measured, 4 months apart over 3 years and were analysed by means of a descriptive statistic and a repeated measures ANOVA with a Bonferoni post-hoc adjustment. Results: No significant chronological age-differences were found between the pre and post menarche groups at baseline. Both groups showed significant annual increases in all body measurements with the pre menarche group showing the highest 4 monthly increases and over time. However, the post-menarche girls stayed non significantly taller and heavier with longer body segments over the follow up period while this group also showed a higher BMI at a younger age. Group differences at baseline were mostly of statistical significance, also showing moderate to strong practical significance. Differences between the groups, however, declined to similar values two years later at 16.25 years, which signifies the end of the pubertal phase. The interaction effects over time were significant for all variable (p<0.05) except for leg-length (p=0.81). Conclusion: Maturational differences during adolescence did contribute to differences in anthropometric growth characteristics of girls. Timing differences in the onset of menarche results in temporary significant anthropometric growth differences, especially at younger ages. Early maturing girls have physiological advantages initially, but these benefits dissipate to more ideal body compositions among late maturing girls that will benefit them in sport at a later age. As differences in growth between early and late maturing girls declined to almost similar values at the end of the pubertal phase, these girls can only be compared realistically, regarding their potential for sport by the end of the pubertal phase at around the age of 16 years.

- Abstract
Emotional awareness and regulation are often associated with improved performance in sports, which raises the question as to the role of emotional intelligence in athletes' optimal performance states. The relationship between emotional intelligence and components of competitive state anxiety levels among a sample of senior-level South African female field-hockey players (n=60, age=21.57±3.65) was determined. The Emotional Intelligence Scale and the Competitive State Anxiety Inventory-2 were applied to collect the data. Descriptive analyses revealed an above-average emotional intelligence and a low somatic/cognitive anxiety, with self-confidence being low to moderate, among players. Direction of cognitive and somatic anxiety was neutral, while selfconfidence levels were facilitative to performance. Pearson's correlation analyses revealed positive associations between players' management of their own and others' emotions and self-confidence, as well as a negative association with cognitive anxiety. A positive association between total emotional intelligence and self-confidence was revealed with results from the simple linear regression analyses, confirming the significant influence emotional intelligence has on players' competitive state anxiety experiences. Essentially, emotional intelligence intervention in aid of controlling cognitive anxiety and improving and maintaining self-confidence is advocated in coaching and sport psychology practice.

- Abstract
This study determined whether anthropometrical, physical, motor and sport psychological differences exist between a group of male adolescents who show talent for sprinting and their less talented counterparts. Grade 8 boys (N=89; mean age: 13.25±0.46 years), from a high school in Potchefstroom voluntarily participated in the study. A general talent identification (TID) protocol and a sport psychological questionnaire were completed. The 40m-sprint test was used to categorise the subjects into two groups. Those in the top 10% were assigned to the talented group (TG) (n=8, mean age=13.79), and the remaining subjects were assigned to the less talented group (LTG) (n=72, mean age=13.55). An analysis of covariance (ANCOVA) was applied with stature as the covariate to adjust for variations in growth status between the two groups. The practical significance of differences between the two groups was determined by means of effect sizes (ES). The level of significance was set at p≤0.05. Significant differences with the potentially talented sprinters, who obtained better scores in upper and lower body explosive power, acceleration, maximal speed, aerobic endurance and in goal setting were found

- Abstract
Problem Statement: Research indicates that early- and late-maturing girls' physical fitness skills are influenced differently by anthropometric changes, initially favouringearly maturing girls. Purpose: The aim of the study, therefore, is to investigate differences in pre- and post-menarche girls' physical fitness capabilities. Approach:: Over three school years, fifty-eight (N=58) girls with a mean age of 13.51±3.51, were divided at baseline into a pre- (n=13) and post-menarche group (n=45) for comparison of muscular power and aerobic endurance. Measurements were taken annually (2010-2012) providing data over three time points. The Australian Sports Commission (1996) protocol was used. Basic statistics, a Spearman correlation analysis, and a repeated-measures ANOVA, adjusted for with a Bonferroni post hoc correction were applied. Results: Developmental differences between the pre- and post-menarche groups were relatively small and insignificant. Early menarche status was to the advantage of power while reaching menarche later positively affected aerobic endurance at younger ages. Changes in these abilities over the follow-up period were different in the groups and levelled out most differences during final measurements. Conclusion: Timing of menarche contributed to differences in muscle power and aerobic endurance of girls, particularly during mid-adolescence, although only on a practical level. The period at and immediately after reaching menarche is characterized by instability, with changes in power and endurance that are associated with menarche status. Influences of somatic and biological growth in same-aged girls of the same age and the influence thereof on power and endurance will only be levelled out 1-2 years after reaching menarche.

- Abstract
The aim of this study was to develop a lower body explosive power (LBEP) prediction model from various physical and motor performance components among a cohort of male and female adolescents living in the Tlokwe local municipality of the North-West Province. A cross-sectional experimental research design was employed with 214 15-year-old adolescents (88 males; 126 females; mean age: 15.8±0.68 years), from six schools, two from the Potchefstroom city area and four from the Ikageng area. They were measured over a 7-day period. Informed consent and demographic questionnaires were completed followed by seven physical and 14 motor performance tests. Regression analyses indicated that gender and 10m - speed formed a significant component-derived prediction model for LBEP values in 15 -year-old adolescents, with gender contributing 39% (R2=0.39) and 10m - speed contributing 7% (R 2=0.07). Results show that 46% (R2=0.46) of the LBEP can be predicted by speed and gender components of adolescents. Variables other than physical and motor performance components contributed 54% to LBEP prediction in adolescents. The results could be used to identify adolescents who show potential to excel in LBEP performance driven sport.

MSc (Counselling Psychology), North-West University, Potchefstroom Campus, 2016 Rugby is regarded as one of the most popular professional team sports in the world and characterized by various high-intensity activities such as sprints, accelerations from a static position, rucking, mauling, tackling and breaking through tackles. In addition to the physical demands players have to deal with, there are also psychological, emotional, social and behavioural demands which need to be addressed. Athletes have to excel in four domains in order to perform at elite levels of sport, namely the physiological, technical, emotional and cognitive levels. The aim of this study was to determine the relationship between measures of cognition (memory capacity, attention and behavioural tasks, sensory-motor functioning, verbal tasks, executive functioning and emotion identification) and on-field performance [as determined by the Key Performance Indicators (KPIs)] of university-level rugby players. A quantitative research method, namely a cross-sectional research design with a convenience sample, was used. A group of 25 male university-level rugby players were recruited from a South African University’s Rugby Institute squad who participated in the Varsity Cup Tournament. The group consisted of eight tight five players (numbers 1-5), five loose forwards (numbers 6-8) and twelve backline players (numbers 9-15) with an average age of 22.63, 22.80 and 21.50 years respectively. The participants’ cognitive functioning was measured using the WebNeuro Sport, a web-based assessment instrument developed by the Brain Resource Company. In order to quantify the players’ on-field performance, the Key Performance Indicators (KPIs) of each player were determined for each game by the full-time, qualified coders of the technical support department of The South African Rugby Union (SARU) by using the technical analysis software, Stratus. The following KPIs were included in the analysis: Attacking variables, including the total number of contributions a player provided during attacking play, carries (number of carries), passes (number of passes a player made), kicks (number of kicks during the game), ball recycler (number of times a player recycled the ball from a maul), breakdown arrivals (number of times a player is part of breakdowns) and attacking mauls (number of times a player was part of an attacking maul. Defensive variables included total number of contributions a player provided during defensive play, tackle attempts (number of attempts), missed tackles (number of tackles missed), breakdown arrivals on defence (number of times a player is part of breakdowns) and defensive mauls (number of times a player was part of a defensive maul). According to our knowledge this is the first study of its kind, which makes a comparison of our findings with existing literature virtually impossible. The analyses of the tight five forwards revealed that players’ sensory-motor ability might contribute to the number of carries the players perform during attacking play. In terms of the loose forwards the positive correlation between total contribution and emotion identification might be indicative of the important role of good pattern recognition and associated quick decision-making. In line with the results of the loose forwards, the analyses of the backs revealed medium to strong positive correlations between emotion identification and total attacking contribution, passes as well as kicks. It therefore appears that good pattern recognition ability and associated quick decision-making might be important cognitive functions for backline players as well as loose forwards to enhance their performance. Although this is the first study of its kind and the fact that most of the explanations are based on hypotheses, it might lay the foundation for further research regarding rugby players’ cognitive functioning and related on-field performance. An important implication of the present findings is that knowledge of the positive as well as the negative relationships and certain measures of cognitive functioning may be of value for improving on-field performance by means of the application of cognitive interventions programs Masters

- Abstract
The objective of this study was to determine whether the sport psychological profiles of talented 13-year-old sport participants differ from less talented participants. 162 grade 8 learners with a mean age of 13.2 ± 0.33 years voluntarily participated in the study. The participants were subjected to the Australian Talent Search protocol and completed the Athlete Coping Skills Inventory for Sport (ACSI-28). The group was categorize according to the median of all the tests of the talent identification protocol (TID) in a talented (TG) and a less talented group (LTG). The TG obtained higher means in all seven sport psychological characteristics: coping with adversity, peaking under pressure, goal setting, confidence, coachability and the average coping profile, concentration and freedom from worry . The results indicate that talented adolescents exhibit specific sport psychological characteristics compared to less talented adolescents.

- Abstract
The purpose of this study was to determine the contribution of selected stressors to the level of stress experienced by South African soccer officials. Forty-two South African Football Association (SAFA) accredited officials, attending a training camp in Potchefstroom, participated in this study. The group comprised of 40 male and two female officials. The average age of the officials was 37.52 (±6.09) years, and the period for which they were accredited as a SAFA official ranged from 2 to 27 years. The Ontario Soccer Officials’ Survey (OSOS) was used to determine the perceived levels of stress. The results indicated that fitness concerns were rated as the highest contributor to the stress experienced followed by role-culture conflicts, fear of failure, peer conflicts, interpersonal conflict, time pressures and lastly, fear of physical harm. The Spearman Rank Order Correlation showed a high correlation between the number of years the officials were accredited with SAFA and the total level of stress they experienced. Furthermore, the results indicated that 60% of the officials, who served as an accredited official for longer than 12 years, experienced five to seven stressors, which contributed to the total level of perceived stress

- Abstract
Long distance running is a moderate to high-power activity supported by aerobic energy (Ward-Smith, 1999). Apart from the importance of aerobic conditioning, long distance running requires a great deal of mental toughness. The purpose of this study was to compare talented, with less talented distance runners, in order to identify the psychological characteristics exhibited by talented distance runners. A cross-sectional study design was used which consisted of 182 grade 8 pupils: 87 boys and 95 girls. Sport psychological skill levels were measured with the Athletic Copings Skills Inventory (ACSI-28). The Australian Talent Search Protocol was used to identify general sporting talent. The results of the beep test were used to identify the most talented potential distance runners. The top 30% (n=58) of the adolescents were assigned to group 1 (talented group) and the remaining adolescents to group 2 (n=107) (less talented). The results revealed that the talented group obtained significantly better results in 6 of the 8 variables which included adversity, pressure, goal-setting, concentration, coachability and the average coping ability (p<0.05). Moderate practical significance was found in 7 of the 8 variables which included adversity, pressure, goal-setting, concentration, confidence, coachability and coping ability, and a small practical significance was indicated for worry. It is therefore, important to consider psychological skill development in young long distance athletes to enhance their athletic performance.

- Abstract
Development of previously disadvantaged communities was identified in South Afria (SA) as a national priority and sport was indicated to be part of such a strategy. Farm schools are among the poorest with regards to financial resources and physical structures in SA and consequently learners are confronted with many constraints regarding sport participation. The aim of this study was to develop a sport development programme for sprinting and long jump that is time effective and requires inexpensive equipment for 10-15 year old black children from farm schools. A pre-test/post-test 2-group research design was used. All girls between the ages 10 and 15 from 2 schools (N=66) who consented to participate in the study were tested by means of the Australian Talent Search protocol and the most talented girls (top 30%) in each school were selected by rank order for further testing by means of a sport specific test battery for the motor abilities underlying successful participation in sprint and long jump. The intervention group (n=19) underwent a development programme for ten weeks conducted twice a week for 1.5 hours and their results were compared to that of a control group (n=18) who did not follow a development programme. The results were analysed by means of independent t-testing and the practical significance of differences was determined by means of effect size. Covariance analysis (ANCOVA) was performed to adjust for pre-testing differences. The intervention programme contributed to improved motor and physical abilities important for performance in both sprints and long jump, namely: flexibility, explosive power, muscle endurance, reaction time, speed, speed endurance, acceleration and long jump. The development programme can successfully develop motor abilities important for successful participation in sprinting and long jump despite various limitations South African farm schools have to deal with.

- Abstract
The most talented subjects (N = 39) were selected from 66 boys by means of a Talent Search testing protocol and then subjected to a sport specific test battery consisting of five anthropometric and 16 physical and motor variables. The results indicated that mean anaerobic power output, acceleration, body mass, reaction time, iliopsoas flexibility, speed endurance, sitting height, age and push-ups contributed to 86.5% of the total variance to performance in the 100 meter sprint. Horizontal jump, age, acceleration and ankle flexibility contributed to 81.5% of the total variance in the performance of the long jump. These anthropometric, physical and motor abilities can enable the coach and Sport Scientist to classify the talent of 10-15 year-old boys for sprinting and long-jumping athletes, and then to develop the potential of the athlete accordingly.

- Abstract
Sixty-two (N=62) boys between the age of 10 and 15 years from two different farm schools in the Potchefstroom district were subjected to a Talent Search testing protocol. Potentially talented athletes (n=21), with a mean age of 12.0 ± 1.67 years, at one of the farm schools were randomly assigned to the experimental group. A control group was selected in the same way consisting of equally talented boys from the other farm school, with an average age of 12.1 ± 1.26 years. The talented children in both groups then underwent a specific test battery designed for sprinting and long jump. Maturity was determined by means of a maturity questionnaire. The development programme contributed statistically significant to the improvement in flexibility, muscle endurance, 0-40 meter speed and long-jump ability. Explosive power, reaction time, speed endurance, acceleration and stride length did not improve. The results revealed that a development programme of 10 weeks had a positive effect on the conditioning of motor and physical abilities and skills for sprinting and long-jump in talented 10 to 15 year old boys, regardless of poor socioeconomic circumstances and a restricted environment.

- Abstract
Investigation of essential competencies in present-day sport psychology practice is critical to keeping the training, education and regulation standards of applied sport psychology (ASP) practitioners at the forefront of research (Fletcher & Maher, 2013). Moreover, investigation is also needed to offer a new rationale for promoting academic inquiry in developed and developing contexts. This study identified essential competencies in contemporary sport psychology practice and explored the comparative views of a purposefully selected sample (n=9) of expert ASP practitioners/psychologists. Data were gathered by means of semi-structured interviews with stakeholders in South Africa (SA) and the United Kingdom (UK). Interview data were analyzed using thematic content analyses. Main findings suggested that a relational and dependable character, a client-centred focus, an all-encompassing counselling skills-set (facilitative and restorative), and explicit expertise in the domains of psychology, sport and sport science are indispensable to current sport psychology practice. Views generated by both stakeholders were remarkably similar and overlapped considerably, which indicated the advanced levels of sport psychology praxis in both contexts. It was recommended that behavioural indicators (personal character) and certain skills prerequisites merit special consideration for candidates entering ASP training and practice. An interdisciplinary training model in ASP with acquired competency in both kinesiology and psychology-based training should become the accepted standard in the training and development of practitioners for the purpose of garnering an inclusive capacity to render client-centred services

- Abstract
In the prediction of lower body explosive power (LBEP), very few researchers have investigated the possibility of making use of anthropometric variables to compile prediction models. Therefore the purpose of this study was to develop a LBEP prediction model from several anthropometric measurements for a cohort of adolescent boys and girls living in the Tlokwe local municipality of the Dr Kenneth Kaunda district in the North West Province, South Africa. This was a cross–sectional experimental design on a purposeively selected cohort of 214 adolescents (15.82±0.68 years) consisting of 88 boys and 126 girls who were part of the Physical Activity and Health Longitudinal Study (PAHLS). Data were obtained by means of skinfold (SF) and LBEP measurements as well as the calculation of maturity age. The results of the forward stepwise regression analysis shows that stature (57%), muscle mass percentage (10%) and maturation age (3%) were the anthropometric variables that served as significant (p

- Abstract
The objective of this study was to compare players' and coaches' perceptions on coaching effectiveness. A total of 155 participants from the Puk Rugby institute (PRI) were available for this study (players, n = 142; coaches, n =13) (age: 18-55 years). Coaches completed the Coaching efficacy scale (CES) and players completed the adapted CES. The CES consists of 24 items measuring four constructs namely motivation, game strategy, technique and character building. Each item was rated on a 10 point Likert scale ranging from 0 (not at all effective) to 9 (extremely effective). High Cronbach alpha values were established for all four constructs on this specific population. Mixed models results indicated a statistical significant difference (p ≤ 0.05) on all four constructs measured when the perceptions of coaches and players were compared. A statistical significant difference exists between the coaches and players' perception regarding the respective coaches' total coaching effectiveness. In view of the inconsistent pattern found between the coaches and players perceptions on coaching effectiveness, coaches and clubs need to be more aware of the impact that players' perceptions have regarding the outcome of coaching effectiveness.

As early as 1994, and with transformation in mind, the African National Congress (ANC) identified the development of the previously disadvantaged communities in South Africa as a national priority. In so doing, sport, among others, was used in this strategy as a medium to improve and change the circumstances of people in disadvantaged communities. Sports development in disadvantaged communities is essential, if taken into consideration that without such further support of the sport talent of some of these children, the needs of these talented children cannot be met and their potential will remain undeveloped. Talent identification (TID), which is based on scientific principles and forms the first step in sports development, still is relatively new in South Africa. Historically, coaches used their own knowledge and experience of the characteristics, which should lead to success in sport as well as participation in competitions in order to do TID. To date, very little research has been done on talent identification and development in sprints and long-jump, especially pertaining to young boy and girl athletes, and in particular concerning athletes from disadvantaged communities. The first and second objectives of this study were to implement sport specific athletics development programmes aimed at improving sprinting and long-jump ability and to determine its effect on the abilities and skills of talented 10 to 15 year-old girls and boys with talent for sprints and long-jump. The third and fourth objectives of this study were to establish which kinanthropometric, physical and motor components will play such a role in 10 to 15 year-olds that it can predict performance ability in sprints and long-jump in girls and boys at this age. The "Australian Talent Search" protocol was used to identify general sport talent in the children (66 girls and 62 boys) who were identified for the study. The talented children (19 girls and 21 boys) from the initial group of were then subjected to a sport specific test battery for sprints and long-jump. The maturation level of the boys was determined by means of a maturity questionnaire, based on the 5 Tanner stages. By using the Statistica and SAS computer programmes, independent t-testing, covariance analyses, correlation coefficients, effect sizes, descriptive statistics as well as a stepwise multiple regression analysis were used to analyze the data with regard to the above-mentioned objectives. A p-value smaller than or equal to 0.05 was accepted as significant. From the results of the study it is evident that the development programmes contributed to the improvement of physical and motor abilities and skills important for performance in both sprints and long-jump in girls (n=19) and boys (n=21) respectively. Among the girls, flexibility, explosive power, muscle endurance, reaction time, speed, speed endurance, acceleration and long-jump showed statistically significant improvement, while abdominal muscle strength and stride length showed no improvement. Secondly, it was established that the development programme contributed statistically significantly to an improvement in flexibility, muscle endurance, 0-40 metres speed and long-jump ability in boys. However, some components did not show improvement, among them explosive power, reaction time, speed endurance, acceleration and stride length. A stepwise multiple regression analysis was used to analyze the third and fourth objectives. It indicated that, in respect to the 100 metres sprint, 7 variables, namely long-jump, push-ups to the point of exhaustion, 7-level abdominal strength, 0-5 metres speed, ankle dorsiflexion, body length and age contributed 84.0% to the total variance in girls. As for long-jump, 7 variables, namely 0-100 metres speed, body length, 7-level abdominal strength, push-ups, ankle dorsiflexion, standing long-jump and body mass proved to be the most important contributors to performance in these items with a total contribution of 79% to the total variance. The fourth objective indicated that average anaerobic power output, acceleration and body mass contributed statistically significantly to performance in the 100 metres sprint in boys with a contribution of 86.5% to the total variance. Horizontal jump, age and acceleration contributed statistically significantly to long-jump performance with a contribution of 81 5% to the total variance. It is evident from this study that sport specific development programmes can successfully be implemented on girls and boys at ages 10-15 in order to improve sprinting and long-jump ability, regardless of poverty-stricken circumstances and poor infrastructure. Furthermore, the study brought to light that specific kinanthropometric, physical and motor abilities exist which can be used to predict performance in sprints and long-jump in girls and boys separately at ages 10 to 15.

- Abstract
Thesis (M.Sc.)--North-West University, Potchefstroom Campus, 2004. The importance of studies on a complete anthropometric profile is stressed due to the lack of literature and due to the fact that athletes' morphological composition is one of the factors that contribute to performance. The purpose of this study was firstly to describe the body composition and somatotypes of international male elite javelin throwers and to identify which variables distinguish the world's elite javelin throwers (n=6) (Group A) from the sub elite throwers (n=13) (Group B) and which variables contribute to their performance. The anthropometrical variables are primarily as described in Norton et al. (1996). Elite javelin throwers were found to have an average body mass of 97.0 kg, stature of 187.5 cm, percentage body fat of 11.9% and percentage muscle mass of 40.4%. The javelin throwers had an average value of 11.2 kg for skeletal mass and expressed as a percentage, an average of 11.7%. The average acromial-radial length (humerus) was 35.5 cm with the radial-stilion length (forearm) 28.7 cm. The javelin throwers had an average bi-iliocristale breadth of 31.9 cm, bi-acromiae breadth of 45.5 cm, A-P chest depth of 21.9 cm and a chest breadth of 33.8 cm. The average wrist breadth was 6.0 cm, ankle breadth 8.1 cm, femur breadth 10.2 and humerus breadth 7.4 cm. The javelin throwers had an average flexed arm girth of 38.3 cm, forearm girth of 30.5 cm, thigh girth of 64.1 cm and calf girth of 40.8 cm. The average somatotypes for the javelin throwers were 2.5-5.9-1.4. Seven variables that best discriminate between the javelin throwers in Group A and the javelin throwers in Group B were determined by using discriminant analysis. The variables were age, body mass, mesomorph, muscle mass, A-P chest depth, chest breadth and arm-span. The forward step-wise discriminant analysis found the variables that best discriminate between the two groups to be age (F=10.53, P

The Bull’s Mental Skills Questionnaire, developed in the United Kingdom, is being more extensively used across various South African sport and exercise settings. It comprises seven mental skill subscales: imagery, mental preparation (goal-setting), self-confidence, anxiety and worry management, concentration, relaxation and motivation. Individual subscale scores are calculated and combined into a total score. Previous research has recommended establishment of local sport code norms. The aim of this study was to establish preliminary South African university norms for rugby, cricket, soccer, athletics, hockey and netball. The sample consisted of 121 university students from a South African institution. Norms are presented in means and standard deviations. Sports code norms are compared. Norms are compared with previous studies using similar samples. Recommendations for future research with the scale are made.

- Abstract
The aim of this study was to develop a lower body explosive power (LBEP) prediction model from various physical and motor performance components among a cohort of male and female adolescents living in the Tlokwe local municipality of the North-West Province. A cross-sectional experimental research design was employed with 214 15-year-old adolescents (88 males; 126 females; mean age: 15.8±0.68 years), from six schools, two from the Potchefstroom city area and four from the Ikageng area. They were measured over a 7-day period. Informed consent and demographic questionnaires were completed followed by seven physical and 14 motor performance tests. Regression analyses indicated that gender and 10m-speed formed a significant component-derived prediction model for LBEP values in 15- year-old adolescents, with gender contributing 39% (R2=0.39) and 10m-speed contributing 7% (R2=0.07). Results show that 46% (R2=0.46) of the LBEP can be predicted by speed and gender components of adolescents. Variables other than physical and motor performance components contributed 54% to LBEP prediction in adolescents. The results could be used to identify adolescents who show potential to excel in LBEP performance driven sport. [ABSTRACT FROM AUTHOR]

- Abstract
This study analysed the growth profiles stature, mass, arm span, sitting height and sitting-height-ratio ofboys during the growth spurt within the mid-adolescent phase. A convenience sample of 73 Grade 8-10 boys (13.58-15.57 years) participated. Measurements were repeated three times annually, four months apart and sitting height ratio was calculated (sitting height/stature X 100). Protocols of the International Standards for Anthropometric Assessment (ISAK) and the Canadian Sports for Life were applied. Repeated measures over time ANO VA with a Bonferonni post hoc correction was use to analyse the data. The most significant increases (p=0.000) in stature, mass, arm span and sitting height occurred between 13.58 and 14.58 years while sitting-height-ratio showed the greatest change (p=0.002) between 14.58 and 15.57 years. Stature, mass and arm span exhibited parallel development up to 15 years after which further development levelled off, while no levelling off occurred in mass increase. The boys in this study entered the growth spurt in height on average prior to 13.58 years, but significant anthropometrical, motor and physical changes still occurred during their first year ofhigh school (Grade 8), where high individual variability in growth changes were still evident.

- Abstract
The purpose of this study was to determine the contribution of selected stressors to the level of stress experienced by South African soccer officials. Forty-two South African Football Association (SAFA) accredited officials, attending a training camp in Potchefstroom, participated in this study. The group comprised of 40 male and two female officials. The average age of the officials was 37.52 (±6.09) years, and the period for which they were accredited as a SAFA official ranged from 2 to 27 years. The Ontario Soccer Officials' Survey (OSOS) was used to determine the perceived levels of stress. The results indicated that fitness concerns were rated as the highest contributor to the stress experienced followed by role-culture conflicts, fear of failure, peer conflicts, interpersonal conflict, time pressures and lastly, fear of physical harm. The Spearman Rank Order Correlation showed a high correlation between the number of years the officials were accredited with SAFA and the total level of stress they experienced. Furthermore, the results indicated that 60% of the officials, who served as an accredited official for longer than 12 years, experienced five to seven stressors, which contributed to the total level of perceived stress.

Long distance running is a moderate to high-power activity supported by aerobic energy (Ward-Smith, 1999). Apart from the importance of aerobic conditioning, long distance running requires a great deal of mental toughness. The purpose of this study was to compare talented, with less talented distance runners, in order to identify the psychological characteristics exhibited by talented distance runners. A cross-sectional study design was used which consisted of 182 grade 8 pupils: 87 boys and 95 girls. Sport psychological skill levels were measured with the Athletic Copings Skills Inventory (ACSI-28). The Australian Talent Search Protocol was used to identify general sporting talent. The results of the beep test were used to identify the most talented potential distance runners. The top 30% (n=58) of the adolescents were assigned to group 1 (talented group) and the remaining adolescents to group 2 (n=107) (less talented). The results revealed that the talented group obtained significantly better results in 6 of the 8 variables which included adversity, pressure, goal-setting, concentration, coachability and the average coping ability (p<0.05). Moderate practical significance was found in 7 of the 8 variables which included adversity, pressure, goal-setting, concentration, confidence, coachability and coping ability, and a small practical significance was indicated for worry. It is therefore, important to consider psychological skill development in young long distance athletes to enhance their athletic performance. [ABSTRACT FROM AUTHOR]

Development of previously disadvantaged communities was identified in South Afria (SA) as a national priority and sport was indicated to be part of such a strategy. Farm schools are among the poorest with regards to financial resources and physical structures in SA and consequently learners are confronted with many constraints regarding sport participation. The aim of this study was to develop a sport development programme for sprinting and long jump that is time effective and requires inexpensive equipment for 10-15 year old black children from farm schools. A pre-test/post-test 2-group research design was used. All girls between the ages 10 and 15 from 2 schools (N=66) who consented to participate in the study were tested by means of the Australian Talent Search protocol and the most talented girls (top 30%) in each school were selected by rank order for further testing by means of a sport specific test battery for the motor abilities underlying successful participation in sprint and long jump. The intervention group (n=19) underwent a development programme for ten weeks conducted twice a week for 1.5 hours and their results were compared to that of a control group (n=18) who did not follow a development programme. The results were analysed by means of independent t-testing and the practical significance of differences was determined by means of effect size. Covariance analysis (ANCOVA) was performed to adjust for pre-testing differences. The intervention programme contributed to improved motor and physical abilities important for performance in both sprints and long jump, namely: flexibility, explosive power, muscle endurance, reaction time, speed, speed endurance, acceleration and long jump. The development programme can successfully develop motor abilities important for successful participation in sprinting and long jump despite various limitations South African farm schools have to deal with.

- Abstract
Sixty-two (N=62) boys between the age of 10 and 15 years from two different farm schools in the Potchefstroom district were subjected to a Talent Search testing protocol. Potentially talented athletes (n=21), with a mean age of 12.0 ± 1.67 years, at one of the farm schools were randomly assigned to the experimental group. A control group was selected in the same way consisting of equally talented boys from the other farm school, with an average age of 12.1 ± 1.26 years. The talented children in both groups then underwent a specific test battery designed for sprinting and long jump. Maturity was determined by means of a maturity questionnaire. The development programme contributed statistically significant to the improvement in flexibility, muscle endurance, 0-40 meter speed and long-jump ability. Explosive power, reaction time, speed endurance, acceleration and stride length did not improve. The results revealed that a development programme of 10 weeks had a positive effect on the conditioning of motor and physical abilities and skills for sprinting and long-jump in talented 10 to 15 year old boys, regardless of poor socioeconomic circumstances and a restricted environment.
