Summary: The purpose of this study was to compare the effects of variable-resistance complex training (VRCT) versus traditional complex training (TCT) on strength, power, speed, and leg stiffness (K-leg) in rugby league players. The results showed that both VRCT and TCT significantly improved 1RM back squat, countermovement jump peak power, and 5-m sprint time. VRCT and TCT can be implemented during the competitive season to improve strength, power, and 5-m sprint time, with VRCT potentially leading to greater improvements in reactive strength index and K-leg, and TCT enhancing 10- and 20-m sprint times.

Summary: This study compares the effects of two resistance training programs on 1RM, CMJ, and sprint, finding that load adjustment based on movement velocity can help control individual responses to training and improve the implementation of RT programs.

Summary: The study found that velocity-based training and traditional percentage-based training were equally effective in improving strength, jump, linear sprint, and change of direction speed, with no significant differences between the two methods.

Summary: This study investigated the associations between kinematic patterns of the torso segment and shoulder joint loading as well as pitching performance in youth pitchers. Specific torso movement patterns were found to be correlated with shoulder joint kinetics and ball speed, with excessive axial rotation potentially increasing shoulder joint loads. Targeted interventions could decrease joint kinetics while maintaining pitching performance.

Summary: This study describes the highest frequency and variability of tackle events in rugby league and investigates seasonal differences. The results suggest that there is a significant variability between different positions in terms of tackle events, ball carrier events, and tackler involvements. Coaches should consider separating players into positional groups for training. Furthermore, there was a significant increase in the number of tackle events in the 2020 season, possibly due to rule changes.

Summary: Current research on LLS is focused on diagnosis, management, graduated return to sports, and resumption of throwing. Studies have indicated a shift towards shorter periods of rest and gradual return to sports rather than complete cessation of throwing. The majority of participants were able to return to any sport participation after a period of rest, with a high proportion returning to their preinjury level of sport.

Summary: This study compared the effects of velocity-based resistance training (VBRT) and percentage-based resistance training (PBRT) on athletic performance in female basketball players. Results showed that VBRT led to significant improvements in various aspects of athletic performance, including vertical jump, squat jump, reactive strength, and jump height, compared to PBRT.

Summary: This study aims to investigate the effects of autoregulatory progressive resistance exercise (APRE) and velocity-based resistance training (VBRT) on the jumping ability of badminton athletes. The results showed that compared to VBRT, APRE can significantly improve the athletes' squat jump height and explosive power in a shorter period of time. These findings have practical implications for coaches seeking to enhance athletes' jumping performance in the short term.

Summary: This study aims to identify important characteristics that classify injurious and non-injurious tackles in rugby league. Six characteristics were found to have relative importance in classifying injurious tackles, including the twisting of the ball carrier's legs, head collision, and use of body weight by the tackler. These findings have implications for reducing injuries in rugby league.

Summary: This study compared the effects of variable-resistance complex training (VRCT) and traditional complex training (TCT) on muscle architecture in rugby league players during a 6-week mesocycle. The results showed that both VRCT and TCT can improve muscle thickness and fascicle length adaptations, but TCT may induce greater changes in muscle architecture, while VRCT has practical value due to the shorter rest interval between resistance and plyometric exercises.

Summary: This study compared the effects of velocity-based training (VBT) and percentage-based training (PBT) on strength, loaded countermovement jump (CMJ), and sprint performance. The results showed that VBT may be more beneficial for improvements in CMJ, sprint, and COD, while PBT may be slightly favorable for individuals focusing on maximal strength. Both training methods improved 1RM and COD times.
