The aim of this study was to analyse the differentiated role played by academic self-concept on teacher identity, taking into account the mediating role of teacher efficacy and the gender of the pre-service physical-education teachers. In this cross-sectional study, 478 master's degree students in Secondary Education Teacher Training participated (M ean = 27.09; SD = 6.32; 54.8% male, 44.8% female, 0.4% other). The following scales were used: academic self-concept, teaching identity, and teacher self-efficacy. After finding significant differences in academic effort, a structural equation analysis (SEM) with the multigroup option was conducted to answer the research objective. The results revealed that the women had significantly higher mean academic effort values than the men. In addition, the SEM, which showed excellent fit indices, revealed that, for the men, teacher efficacy acted as a mediating variable between academic confidence and teacher identity. In contrast, for the women, teacher efficacy acted as a mediator between academic effort and teacher identity. However, academic effort also acted as a direct predictor of teacher identity in male pre-service teachers. As a main conclusion, it can be said that the findings highlight the importance of academic self-concept in undertaking the master's degree by increasing teacher identity through the teaching efficacy of pre-service teacher educators.

Heart rate variability (HRV) is considered one of the most relevant indicators of physical well-being and relevant biomarker for preventing cardiovascular risks. More recently, a growing amount of research has tracked an association between HRV and cognitive functions (i.e., attention). Research is still scarce on spatial orientation, a basic capability in our daily lives. It is also an important indicator of memory performance, and its malfunctioning working as an early sign of dementia. In this study, a total of 43 female students (M Age = 18.76; SD = 2.02) were measured in their lnRMSSD using the photoplethysmography technique with the Welltory smartphone app. They were also tested in their spatial memory with The Boxes Room, a virtual navigation test. Measures of physical activity were obtained with the International Physical Activity Questionnaire (IPAQ). Correlation analyses and repeated measures ANOVA were performed, comparing participants with high / low lnRMSSD in their spatial performance. Results showed that, at an equal level of physical activity, participants with a higher lnRMSSD were more effective in the early trials of The Boxes Room, being more precise in estimating the correct position of the stimuli. Moreover, a subsequent simple linear regression showed that a higher lnRMSSD was related to a smaller number of errors at the beginning of the spatial task. Overly, these results outline the relationship between HRV and navigation performance in early stages of processing, where the environment is still unknown and the situation is more demanding., Competing Interests: Declaration of competing interest None., (Copyright © 2024.

High-intensity interval training is the gold standard for cardiac rehabilitation although current revascularization therapy focuses on the recovery of autonomic nervous system balance through heart rate variability (HRV). The main objective was to analyze the effect of HRV-guided training versus high-intensity interval training on cardiorespiratory fitness, heart rate variability, quality of life, and training volume at high intensity, as well as exercise adherence, safety, and feasibility in ischemic patients. This is an 8-week cluster randomized controlled trial with an HRV-based training group (HRV-G) and a traditional HIIT group (HIIT-G). Maximal oxygen consumption, heart rate, and blood pressure were measured during the Bruce protocol treadmill test. HRV was measured with the HRV4Training application, and quality of life with the MacNew QLMI. The repeated measures ANCOVA was used with the age and the baseline scores as covariables. Forty-six patients (mean age 55 ± 11.03 years) were randomized and assigned either to HRV-G (n = 23) or HIIT-G (n = 23). Both groups improved maximal oxygen consumption and METS (P > .05). However, the resting systolic blood pressure was lower in HRV-G (4.3 ± 1.2 mmHg, P = .05). In HRV-G, the resting diastolic, maximal diastolic, and systolic blood pressure decreased (5.4 ± 5.96 mmHg, P = .007; 11.4 ± 12.46 mmHg, P = .005; and 5 ± 5.98 mmHg, P = .013, respectively) whereas the recovery heart rate increased significantly (-21.5 ± 23.16 beats/min, P = .003). The LnrMSSDcv ([LnrMSSD SD /LnrMSSD MEAN ] × 100) was lower in HRV-G (1.23 ± 0.91 mmHg, P = .03) while the training volume at high intensity was higher in HIIT-G (31.4 ± 29.2 min, P = .024). HRV-guided training presents a better cardioprotective effect than HIIT-G at a lower high-intensity training volume., (© 2023. The Author(s), under exclusive licence to American Aging Association.)

Previous research has looked at the positive consequences generated by teacher-generated climates on the motivational experiences of pre-service teachers. However, there is scant research focusing on the adverse motivational consequences that affect the perceptions of future teachers during the training process. The objective of this study was to explore the dark side of Duda's multidimensional conceptualization, its influence on academic engagement, and the intention of pre-service teachers to be educators. A total of 1,410 university students in initial teacher training (including physical education pre-service teachers) (59.6% women; 40.3% men; 0.1% other; M age = 23.85; SD = 5.13) participated. The following scales were used: disempowering motivational climate, frustration of basic psychological needs, academic motivation, academic engagement, and the intention to choose teaching. The results of the structural equation model with latent variables show the positive prediction of the disempowering climate on the dark side and its negative influence on the intention to be a teacher. Controlled motivation preceded by academic engagement significantly mediates the relationship between a disempowering climate and the intention to be a teacher, increasing the total effect on the latter variable. Therefore, this research highlights for both teachers and researchers the impact of a disempowering motivational style, as well as its influence on the dark side as a negative promoter in trainee teachers regarding their intention to become teachers.

COVID-19 and the resulting confinement has had a great impact on the educational environment. Although research in initial teacher education has focused on studying the factors that lead to increased academic engagement, there is no evidence that examines the role of teacher interpersonal style and motivational classroom in a virtual learning context. The aim of this research was to analyze the mediating role of motivational climate between teacher interpersonal style (i.e., autonomy support and controlling style) and academic engagement climate in pre-service teachers in a resilient context. The research design was observational, descriptive, cross-sectional, and non-randomized. A total of 1,410 university students (pre-service teachers) participated ( M age = 23.85; SD = 5.13) (59.6% female; 40.3% male; 0.1% other). The scales of interpersonal teaching style, classroom motivational climate, academic commitment, and resilience were used, and a structural equation analysis with latent variables was carried out controlling resilience and gender. The results of the structural equation model show the importance of student perception of teacher autonomy support on academic engagement of the pre-service teachers, as well as the mediation of the mastery climate between autonomy support and academic engagement. For this reason, in order to increase academic engagement in pre-service teachers, it is recommended the use of motivating styles and instructional strategies focused on supporting the decision-making process, initiative, and significant learning., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 López-García, Carrasco-Poyatos, Burgueño and Granero-Gallegos.)

There are many consequences associated with having a stroke, all of which are important factors affecting long-term rehabilitation outcomes; these become important health issues for those of advanced age and require dedicated health strategies. High-intensity interval training (HIIT) is an effective training protocol used in cardiac rehabilitation programs; however, owing to the inter-individual variability in physiological responses to training associated with cardiovascular diseases, the exercise regimen given to each patient should be closely controlled and individualized to ensure the safety and efficiency of the exercise program. Heart rate variability (HRV) is currently being used for this purpose, as it is closely linked to parasympathetic nervous system activation, with high HRV scores associated with good cardiovascular adaptation. The objective of this protocol is to determine the effect of HIIT compared to HRV-guided training in terms of cardiorespiratory fitness, heart rate variability, functional parameters, body composition, quality of life, inflammatory markers, and cognitive function in patients who have had a stroke, as well as to assess the feasibility of patients undertaking an 8-week cardiac rehabilitation program, evaluating its safety and their adherence. The proposed protocol involved cluster-randomized controlled design in which the post-stroke patients are assigned either to an HRV-based training group (HRV-G) or a HIIT-based training group (HIIT-G). HIIT-G will train according to a predefined training program, whereas HRV-G will train depending on the patients' daily HRV. The outcomes considered are peak oxygen uptake (VO 2peak ), endothelial and work parameters, heart rate variability, functional parameters, relative weight and body fat distribution, quality of life, inflammatory markers and cognitive function, as well as exercise adherence, feasibility, and safety. It is expected that this HRV-guided training protocol will improve functional performance in patients following a stroke and be safer, more feasible, and generate improved adherence relative to HIIT, providing an improved strategy for to optimize cardiac rehabilitation interventions.

There is a lack of studies that analyze the interaction between risk variables as predictors of back pain (BP) in adolescents. The objectives of this study were to examine the relationship between BP and several risk variables, and to analyze the effect of the mediation of gender in this association. This cross-sectional study included n = 617 adolescents (mean age: 14.10 ± 1.18 years old) who completed the BP Adolescent Survey and who performed the bench trunk curl (BTC) and Sorensen (SOR) tests. Males showed a significantly lower prevalence (OR: 0.67) and frequency (contingency coefficient: 1.73) of BP than females, less participation in leisure-time sedentary behaviors (LRSBs) per day of more than 2 h (Cramer's V: 0.110), a higher sufficient Physical Activity (PA) (Cramer's V: 0.323) and a higher score in the BTC test (Contingency coefficient: 0.346). A high BTC score indicated significantly lower risk of BP than mid (OR: 1.74; p = 0.025) or low (OR: 1.62; p = 0.022) BTC. The mediation analysis showed a significant indirect effect with a significant value for the Sobel test (z = 7.45 ± 0.111). When the BTC test value was included in the equations, the connection between gender and BP was no longer significant. There was a difference in the prevalence between gender in BP and LRSB and PA. BP was associated with the SOR test. The association between BP and gender was mediated by SOR results.

Purpose: To analyze the training structure following a heart rate variability (HRV) -guided training or traditional training protocol, determining their effects on the cardiovascular performance of professional endurance runners, and describing the vagal modulation interaction., Methods: This was an 8-week cluster-randomized controlled trial. Twelve professional endurance runners were randomly assigned to an HRV-guided training group (HRV-G; n = 6) or a traditional training group (TRAD-G; n = 6). The training methodology followed by the HRV-G was determined by their daily HRV scores. Training intensities were recorded daily. HRV4Training was used to register the rMSSD every morning and during a 60-second period. Cardiovascular outcomes were obtained through an incremental treadmill test. The primary outcome was the maximal oxygen uptake (VO 2max )., Results: Total training volume was significantly higher in TRAD-G, but moderate intensity training was significantly higher in HRV-G (X ± SD Dif =1.98 ± 0.1%; P = 0.006; d = 1.22) and low intensity training in TRAD-G (X ± SD Dif =2.03 ± 0.74%; P = 0.004; d = 1.36). The maximal velocity increased significantly in HRV-G (P = 0.027, d = 0.66), while the respiratory exchange ratio increased in TRAD-G (P = 0.017, d = 1). There was a small effect on the LnRMSSD increment (P = 0.365, d = 0.4) in HRV-G. There were statistical inter-group differences in the ∆maximal heart rate when ∆LnrMSSD was considered as a covariable (F = 7.58; P = 0.025; d = 0.487). There were significant and indirect correlations of LnRMSSD TEST with VO 2max (r =-0.656, P = 0.02), ∆LnrMSSD with ∆VO 2max (r = -0.606, P = 0.037), and ∆LnrMSSD CV with ∆VENT (r = -0.790, P = 0.002)., Conclusions: higher HRV scores suggest better cardiovascular adaptations due to higher training intensities, favoring HRV as a measure to optimize individualized training in professional runners., (Copyright © 2021 Elsevier Inc.

A systematic review with meta-analysis was conducted to evaluate the effects of circuit resistance training (CRT) on cardiorespiratory fitness, strength, and body composition in middle-aged and older women. Sixteen studies were included in the meta-analysis. The CRT interventions led to a significant decrease in weight, body mass index, and fat mass along with an increase in muscle mass. Significant differences were found in the fat mass and a trend to develop muscle mass when compared with the control group. CRT led to a significant increase in VO2max, walking endurance, and time to exhaustion; likewise, significant differences were observed when compared with the control group. CRT had a moderate and large favorable effect on arm, trunk, and lower limb strength. Furthermore, the increases in strength observed in the CRT were significantly greater than the changes observed in the control group. In middle-aged and older women, CRT improved cardiorespiratory fitness and strength and optimized body composition.

This review aimed to synthesize evidence regarding interventions based on heart rate variability (HRV)-guided training for VO 2max improvements in endurance athletes and address the issues that impact this performance enhancement. The Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, CINAHL Complete, the Web of Science Core Collection, Global Health, Current Contents Connect, and the SciELO citation index were searched. Inclusion criteria were: randomized controlled trials; studies with trained athletes enrolled in any regular endurance training; studies that recruited men, women, and both sexes combined; studies on endurance training controlled by HRV; studies that measured performance with VO 2max . A random-effects meta-analysis calculating the effect size (ES) was used. Moderator analyses (according to the athlete's level and gender) and metaregression (according to the number of participants in each group) were undertaken to examine differences in ES. HRV-guided training and control training enhanced the athletes' VO 2max ( p < 0.0001), but the ES for the HRV-guided training group was significantly higher ( p < 0.0001; ES HRVG-CG = 0.187). The amateur level and female subgroup reported better and significant results ( p < 0.0001) for VO 2max . HRV-guided training had a small (ES = 0.402) but positive effect on endurance athlete performance (VO 2max ), conditioned by the athlete's level and sex.

Physiological training responses depend on sympathetic (SNS) and parasympathetic nervous system (PNS) balance. This activity can be measured using heart rate variability (HRV). Such a measurement method can favor individualized training planning to improve athletes' performance. Recently, HRV-guided training has been implemented both on professional and amateur sportsmen and sportswomen with varied results. There is a dearth of studies involving professional endurance athletes following a defined HRV-guided training protocol. The objectives of the proposed protocol are: (i) to determine changes in the performance of high-level athletes after following an HRV-guided or a traditional training period and (ii) to determine differences in the athletes' performance after following both training protocols. This will be a 12-week cluster-randomized controlled protocol in which professional athletes will be assigned to an HRV-based training group (HRV-G) or a traditional-based training group (TRAD-G). TRAD-G will train according to a predefined training program. HRV-G training will depend on the athletes' daily HRV. The maximal oxygen uptake (VO 2max ) attained in an incremental treadmill test will be considered as the primary outcome. It is expected that this HRV-guided training protocol will improve functional performance in the high-level athletes, achieving better results than a traditional training method, and thus providing a good strategy for coaches of high-level athletes.

High-intensity interval training (HIIT) has similar or better effects than moderate-intensity continuous training (MICT) in increasing peak oxygen consumption (VO 2max ), however, it has not been studied when HIIT is applied in a circuit (HIICT). The aim of this study was to compare the effects of a HIICT versus MICT on VO 2max estimated (VO 2max -ES), heart rate (HR) and blood pressure (BP) of middle-aged and older women. A quasi-experimental randomized controlled trial was used. Fifty-four women (67.8 ± 6.2 years) were randomized to either HIICT ( n = 18), MICT ( n = 18) or non-exercise control group (CG; n = 18) for 18 weeks. Participants in HIICT and MICT trained two days/week (one hour/session). Forty-one participants were assessed (HIICT; n = 17, MICT; n = 12, CG; n = 12). Five adverse events were reported. Cardiorespiratory fitness, HR and BP were measured. The tests were performed before and after the exercise intervention programs. VO 2max -ES showed significant training x group interaction, in which HIICT and MICT were statistically superior to CG. Moreover, HIICT and MICT were statistically better than CG in the diastolic blood pressure after exercise (DBP ex ) interaction. For the systolic blood pressure after exercise (SBP ex ), HIICT was statistically better than CG. In conclusion, both HIICT and MICT generated adaptations in VO 2max -ES and DBP ex . Furthermore, only HIICT generated positive effects on the SBP ex . Therefore, both training methods can be considered for use in exercise programs involving middle-aged and older women.

Background: The neuromuscular decline impact in the functional independence of older women is determining the necessity of implementing new strategies focused on core strength training and postural stability maintenance to promote healthy aging., Objectives: To define whether Pilates or resistance training is better at improving (a) core isometric and isokinetic muscular strength, and (b) static and dynamic balance, in older women., Methods: This was a cluster randomized controlled trial. Physically independent older women (60-80 years) from day centers were randomly allocated to Pilates, Muscular and Control Groups (PG, MG and CG) using a block randomization method. Only the research staff performing the assessment and statistical analysis were blinded. Exercise groups trained twice a week (1 h per session) for 18 weeks in a moderate-to-vigorous intensity. Core strength (primary outcome): trunk and hip isometric and hip isokinetic muscular strength (Biodex System III Pro Isokinetic Dynamometer), alongside one leg static balance (portable force platform Kistler 9286AA) and dynamic balance (timed up and go (TUG)) were assessed., Results: A total of 60 participants were randomized (PG, n = 20; MG, n = 20; CG, n = 20) and 49 completed the trial (PG, n = 16; MG, n = 19; CG, n = 14). Regarding hip isometric extension strength, PG was statistically better than CG ( P = 0.004). There were no differences between groups regarding isokinetic strength or balance. Intra-group comparisons showed significant improvements ( P < 0.05) in the dynamic balance and trunk and hip isometric extension strength for PG and MG, whereas every hip isokinetic measurement was improved in MG. Exercise programs did not produce any adverse event., Conclusions: The Pilates training program was more effective for improving isometric hip and trunk extension strength, while the Muscular training program generated greater benefits on trunk and hip isokinetic strength. Moreover, both training programs showed moderate effects for the TUG., Clinical Trial Registration: The trial was registered at ClinicalTrials.gov (identifier: NCT02506491)., Competing Interests: The authors declare that they have no competing interests., (© 2019 Carrasco-Poyatos et al.)

The literature suggests that high-intensity interval training (HIIT) is more effective than moderate-intensity continuous training (MICT) to improve functional ability. However, there is no evidence on including HIIT in a circuit programme (HIICT). Our objective was to determine what type of training (HIICT or MICT) induces greater adaptations in the functional ability and body mass index of middle-aged and older women. The study used a quasi-experimental randomized controlled trial with 54 participants (age = 67.8 ± 6.2 years). Participants were randomly allocated to HIICT ( n = 18), MICT ( n = 18) or a non-exercise control group (CG; n = 18). The participants in the HIICT or MICT groups trained twice a week (1 h/session) for 18 weeks. Forty-one subjects were analysed (HIICT; n = 17, MICT; n = 12, CG; n = 12). Five subjects presented adverse events during the study. Strength, gait, cardiorespiratory fitness, balance and body mass index were measured. A significant training x group interaction was found in the arm curl test, where HIICT was statistically better than MICT and CG. Likewise, HIICT was statistically better than the CG in the BMI interaction. In lower limb strength, gait/dynamic balance and cardiorespiratory fitness, both HIICT and MICT were statistically better than the CG. In conclusion, HIICT generated better adaptations in upper limb strength than MICT. Likewise, HIICT generated better adaptations in body mass index than CG. Finally, both HIICT and MICT had a similar influence on strength, cardiorespiratory fitness and gait/dynamic balance.

Background: and purpose. Trunk endurance and extensibility are the main physical condition factors related to back pain. The goal was to analyse the effectiveness of a 6-week Pilates programme on trunk endurance and extensibility in adolescents with a history of back pain, determining the influence of sex., Materials and Methods: Fifty-two students with a history of back pain were randomly assigned to the Pilates group (PG; n = 26) or the control group (CG; n = 26). Trunk flexion (BTC test) and extension (SOR test), and hamstring extensibility (TT test) were measured., Results: PG improved significantly BTC, SOR, and TT test. Statistical differences (p = 0.005) were found between the PG and the CG for the SOR test., Conclusion: The Pilates programme enhanced trunk endurance and extensibility in adolescents with a history of back pain. Trunk flexor endurance was better in the PG. Results were not influenced by sex., (Copyright © 2019 Elsevier Ltd. All rights reserved.)

Objectives: The goal was to analyze the effect of two different training programs on functional autonomy, balance, and body composition in aged women and to determine the influence of their cognitive function., Methods: Older women aged between 60 to 80 years old were invited to participate in the study. A block randomisation method was used to allocate participants to the Pilates group (PEP), the Muscular group (MEP) and the control group (CG) with equal sample sizes (n = 20). PEP or MEP were required to train twice a week (1 hour/session) in a moderate to vigorous intensity for 18 weeks. Functional autonomy was assessed with the GDLAM protocol. The cognitive function, withthe Mini-Mental State (MMS). Static balance, with a force platform (Kistler 9286AA). Body composition, with a dual-energy X-ray bone densitometry. Research staff performing the assessment and statistical analysis was blinded., Results: Eighty participants were randomized, 16 women did not meet the inclusion criteria and 4 refused to participate. 60 participants were analysed. Either Pilates or Muscular group improved significantly (P ≤ 0.05) in every GDLAM test. Pilates had a better general functional condition index (IG) than the Muscular group (P = 0.042). There was a significant interaction (P ≤ 0.05) between the cognitive function and two items of the GDLAM test. The amplitude of displacement of the center of pressure in the antero-posterior plane decreased significantly in the Muscular group (P = 0.04). The total lean body increased in the Pilates (P =< .001) and the Muscular groups (P = 0.05)., Conclusions: Pilates should be recommended for improving the general functional condition of older women, while the Muscular exercise is effective for enhancing the static balance. Both exercise programs are effective for increasing the total lean body. The cognitive function interacts with some functional autonomy parameters Trial registration: ClinicalTrials.gov (identifier: NCT02506491; available from https://clinicaltrials.gov/show/NCT02506491)., (Copyright © 2018 Elsevier Inc.

Introduction and Objectives: High-interval intensity training (HIT) has been suggested to improve peak VO 2 in cardiac rehabilitation programs. However, the optimal HIT protocol is unknown. The objective of this study was to identify the most effective doses of HIT to optimize peak VO 2 in coronary artery disease (CAD) and heart failure (HF) patients., Methods: A search was conducted in 6 databases (MEDLINE, Web of Science, LILACS, CINAHL, Academic Search Complete, and SportDiscus). Studies using a HIT protocol in CAD or HF patients and measuring peak VO 2 were included. The PEDro Scale and Cochrane Collaboration tools were used., Results: Analyses reported significant improvements in peak VO 2 after HIT in both diseases (P = .000001), with a higher increase in HF patients (P = .03). Nevertheless, in HF patients, there were no improvements when the intensity recovery was ≤ 40% of peak VO 2 (P = .19) and the frequency of training was ≤ 2 d/wk (P = .07). There were significant differences regarding duration in CAD patients, with greater improvements in peak VO 2 when the duration was < 12 weeks (P = .05). In HF, programs lasting < 12 weeks did not significantly improve peak VO 2 (P = .1)., Conclusions: The HIT is an effective method for improving peak VO 2 in HF and CAD, with a significantly greater increase in HF patients. The recovery intervals should be active and be between 40% and 60% of peak VO 2 in HF patients. Training frequency should be ≥ 2 d/wk for CAD patients and ≥ 3 d/wk for HF patients., (Copyright © 2018 Sociedad Española de Cardiología. Published by Elsevier España, S.L.U. All rights reserved.)

Introduction: Being physically active is related to a better physical functioning in older people, but daily physical activity impact in specific outcomes such as osteoporosis or sarcopenia is still not clear., Objective: The main objective of this study is to determine the impact of daily physical activity (DPA) in the bone mineral density and grip strength of old women. The secondary objective is to distinguish between weekday and weekend day scores., Methods: Forty-two women between 65 and 79 years participated. DPA was monitored with the accelerometer ActiGraph GT3X (Pensacola, FL, USA) placed on the dominant hand wrist. Bone mineral density was measured with dual-energy X-ray absorptiometry (AccuDEXA, SHICK, USA) in the central finger of the dominant hand; and grip strength, with a Takei dynamometer (TKK 5001)., Results: There were statistical differences between moderate and vigorous DPA in age, T-score, physical activity counts/min and min/day, and grip strength. Weekend minutes correlated significantly with all the variables. Age was a confounding factor., Conclusions: Higher DPA intensities accomplished by our old women sample preserve T-score (bone standard deviations respect to young, healthy people) and grip strength in a normal range. These results are strongly influenced by weekend scores. Age should be controlled by shorter ranks.

Introduction: Low energy intake may lead to the loss of muscle mass, menstrual dysfunction, increased risk of fatigue, injures and the need for prolonged recovery process., Objectives: 1) To analyse the adherence to the Mediterranean diet of a elite female athletes futsal population, 2) To analyse the relationship between the Dietary Mediterranean index, body composition and sport performance, and 3) To analyse if the differences in the index of adherence to the Mediterranean diet generates test differences in sports performance and body composition., Methods: The adherence to a Mediterranean Diet, body composition test, isokinetic test, vertical jump test (CMJ and SJ), kicking ball, speed test and test Repeated Sprint Ability (RSA) was measured., Results: we found that 7 out of 12 players (58.33%) showed a low index and 5 of the 12 players (41.67%) showed a means index. We found that 7 out of 12 players (58.33%) showed a low index and 5 of the 12 players (41.67%) below the optimum index. Moreover, this adhesion index did not correlate with the values of the body composition or athletic performance test. No significant differences between the players that scored below the optimal index with those with a low level of adhesion were observed. However, mass fat (%) correlated to the ability to repeat sprint., Conclusions: Low levels of adherence to the Mediterranean diet was observed in futsal players, the values shown in the KIDMED questionnaire did not correlate with the performance of the players nor body composition., (Copyright AULA MEDICA EDICIONES 2014.
