To compare acute neuromuscular, metabolic, and perceptual responses to a Brazilian jiu-jitsu specific training model (BJJ-STM) in relation to a simulated match (SM). Ten male adults and experienced BJJ athletes (aged: 22.6 ± 3.1 years, body mass: 81.6 ± 11.0 kg), were randomized to STM or SM, with an interval of five to seven days between sessions. The STM protocol was composed of 5 s of loaded (40% of their body mass) countermovement jumps (LCMJ) interspersed by movements following the BJJ temporal structure (25 s of low-intensity: 5 s of high-intensity). Both conditions (BJJ-STM and SM) lasted 10-min. Before and after each protocol, muscular strength, power, and endurance tests were applied, and physiological (blood lactate and heart rate-HR) and perceptive (rating of perceived exertion-RPE) measures were collected. Blood lactate raised significantly (P < 0.001), while CMJ (P = 0.01), sit-ups, and push-ups in 1 minute (both P < 0.001) decreased after both BJJ-STM and SM. For between-conditions, isometric handgrip strength (minimum and maximum) showed significantly lower responses after SM (P = 0.01 and P = 0.02, respectively). HR-related variables (P = 0.50), and medicine ball throw (P = 0.47) did not differ between protocols. Perceived recovery (TQR) was identical between conditions and RPE was higher after the STM (P = 0.008). The specific training proposed here seems to closely mimic the effects of a BJJ SM. However, the choice of exercises is essential to modulate training responses. [ABSTRACT FROM AUTHOR]

The purpose of this study was to compare the dominant and non-dominant legs in respect of dynamic and static balance and to examine the effect of sport type, sportive experience and BMI on the static and dynamic balance of adolescent male judoists and wrestlers. The results of the study could be beneficial for the prevention of injury to the athletes and could be applied to training management. The study included 54 healthy, male, adolescent wrestlers and judoists (mean age: 15.81 ± 0.87 years; height: 165.01 ± 8.73 cm; weight: 62.01 ± 11.94 kg). Static and dynamic balance were assessed using the flamingo balance test (FBT) and the star excursion balance test (SEBT) in an institution-based sports sciences department. No statistically significant differences were determined between the dominant and non-dominant leg in the normalized SEBT reach distances (P > 0.05). The static balance performance scores were compared between the groups and the judoists were found to have higher static balance performance than the wrestlers (P < 0.05). Both adolescent judoists and wrestlers were found to have higher static and dynamic balance scores compared to other sports branches, and the judoists were determined to have better static and dynamic balance performances than the wrestlers.

Although there are reports in the recent literature demonstrating the epidemiology of injuries in the wrestler population, no study could be found which has investigated the effect of posture on the functional movement patterns in wrestlers. This study was planned to investigate the effect of posture on the Functional Movement Screen (FMS) scores in wrestlers. The study included 68 male (30 greco-roman and 38 freestyle) wrestlers. Spine posture and flexibility were measured via Spinal Mouse (SM). The New York Posture Rating (NYPR) and FMS Test Kits were used to evaluate overall body posture and functional movement patterns, respectively. Significant weak correlations were found between the FMS sub-parameters, SM sub-parameters and NYPR total score (ρ = −0.265–0.297; P < 0.05). There was a significant weak to moderate relationship between FMS and SM spine-check sub-parameters (ρ = −0.262–0.372; P < 0.05). A significant weak to moderate correlation was found between NYPR sub-parameters for abdominal, chest, foot, shoulder and head postures and all FMS sub-parameters excluding rotation stability (ρ = 0.329–0.504; P < 0.05). There was no relationship between FMS, SM and NYPR total scores. Postural deviations in wrestlers especially in the columna vertebralis may disrupt the biomechanical alignment of the upper and lower extremities, causing the joints to fail to perform arthrokinematic and osteokinematic movements at the appropriate angles, increasing the risk of injury to the wrestlers. The results of this study, in which the general body postures of wrestlers were evaluated and monitored, showed that the effects of posture on functional movements patterns help to predict the risk of injury and can play a protective role in wrestlers.

Abstract: Introduction: The goal of this study was to verify if cortisol could be used as an indicator of work load during a mixed aerobic and anaerobic training. Results: Throughout a 15-week training period in 12 young wrestlers, salivary cortisol was assayed every three weeks and the explosive stength was evaluated on weeks 4 and 15. The results show that the wrestlers who have the highest mean levels of cortisol are those which progress less in explosive force (r =−0.72, P <0.01). Conclusion: It seems that the follow-up of cortisol should be an indicator of the load of training. [Copyright &y& Elsevier]
