“…It could be that the lack of effects of resistance exercise programs on CoD performance in some studies [ 30 , 31 ] was observed because EXT and FLX strength training was overemphasized at the expense of other muscle groups. Accordingly, based on the increases in CoD test times following trunk muscle fatigue protocol, Roth et al [ 32 ] have suggested that trunk strength should not be neglected when aiming at improving CoD ability, although leg fatiguing did induce even larger negative effects. Moreover, it was shown that lateral pelvic tilt range during the change of direction cutting maneuver was associated (r = 0.55) with worse performance times.…”

Change-of-direction (CoD) ability is an important determinant of athletic performance. Muscle strength is among the most important determinants of CoD ability. However, previous studies investigating the relationship between CoD ability and muscle strength focused mostly on flexor and extensor muscle groups, or used multi-joint exercises, such as jumps, squats or mid-thigh pull. The purpose of the present study was to investigate the relationship between CoD ability and strength of ankle, knee, hip and trunk maximal and explosive strength. The participants (n = 327), consisting of male and female basketball players, tennis players and long-distance runners completed isometric strength assessments and CoD testing (90° and 180° turn tests). The times of both CoD tests were associated with muscle strength (peak torques and the rate of torque development variables), with correlation coefficients being mostly weak to moderate (r = 0.2–0.6). Strength variables explained 33%, 62% and 48% of the variance in the 90° turn task, and 42%, 36% and 59% of the variance in the 180° turn task, in basketball players, long-distance runners and tennis players, respectively. Hip and trunk muscle strength variables were the most prevalent in the regression models, especially hip adduction and abduction strength. Our results suggest that the strength of several lower limb muscles, in particular of the hip abductors and adductors, and trunk muscles, but also hip rotators, extensors and flexors, as well as knee and ankle flexors and extensors should be considered when aiming to improve CoD performance.

Introduction Athletes are prone to local muscle fatigue due to high-intensity training and to long-term accumulation of musculoskeletal injuries. Musculoskeletal complications represent a large proportion of occupational health problems and, for this reason, have received increased attention from the sports industry. In this sense, studies on muscle fatigue should be intensified. Objective Verify muscle fatigue and injury involving the strain characteristics of lower limb joints in the eccentric and centripetal contraction of the jump. Methods A total of 691 individuals aged 20 to 40 years were selected. Fatigue was caused by active muscle contraction. The characteristic curves of active muscle contraction in different isometric, isotonic, and isokinetic training were analyzed. The degree of fatigue caused by three different sports states was tested by experimentation. The corresponding active muscle contraction characteristics were also analyzed. The potential for homeostasis at different ages was compared. Results The delay in recovery to fatigue is directly proportional to the athlete’s age. The return to post-exercise relief proportion from fatigue gradually decreases. Conclusion The experimental results showed that active muscle contraction could reduce exercise fatigue to some extent. This beneficial biochemical property of active muscle contraction is not found in people with advanced age. The findings have a guiding potential for the relief of sports fatigue. Evidence Level II; Therapeutic Studies - Investigating the result.

This study aims to identify the talents of prospective athletes aged 11-15 years through anthropometric, fundamental skills, and biomotor. Researchers conducted an assessment of these three factors to decide whether the candidate was a gifted athlete. The method used is survey and percentage analysis. The participants who took part in this study were 408 (242 males and 166 females) aged 11-15 years. The results of the assessment from the city of Salatiga showed that there were no very talented participants, 2% of participants were declared talented, 12% quite talented, 44% less talented, and 42% not talented. The percentage analysis showed that there were no very talented participants; less than 1% were talented; 3% were moderately talented; 22% were less talented, and 75% were not talented. There is a difference in catch indicators for male and female participants with a percentage of 30.11%. Talent identification that can be decided in this study, based on the results of anthropometry, fundamental skills, and biomotor measurements is in the javelin throw, sprint 100 meters, 200 meters and long jump. The results of this study conclude that the assessment of anthropometry, fundamental skills, and bimotor can be used to identify the talent of athletes at a young age. It could be concluded that biomotor and anthropometry aspects are more dominantly used to identify athletes but need to be added to other skills performance assessments to support this decision. Future research should focus on identifying the determinants of talent and developing assessment instruments.
