Evaluating Differential Basic Resistive Skills Training Effects on Sprint, Jump, and Agility in Young Basketball Athletes.

Abstract

Objectives: This study examined how differential basic resistive skills training influences basketball players' physical performance. Methods: Seventeen young male athletes completed two weekly sessions of bodyweight strength exercises based on movement variability for 6 weeks. Countermovement jump (CMJ), sprinting, and change of direction (COD) tests were used to evaluate performance before and after the intervention and after a retention phase. Based on previous research, the experimental group followed a differential strength training protocol incorporating movement fluctuations to promote adaptability alongside basketball training. The control group only engaged in standard basketball training. Results: Bayesian analysis showed moderate improvements in sprint performance (0-20 m and 10-20 m sprinting times) for the experimental group, though these gains were not sustained during the retention phase. Slight, non-significant increases in CMJ left leg height were observed, and no significant differences were found in COD performance. Conclusions: The findings suggest that differential strength training may enhance sprint performance and adaptability in young athletes. However, the findings suggest that modifications to the training protocol, such as increasing training volume (e.g., from one set to three sets of 10 repetitions) or incorporating external resistance (e.g., medicine balls, kettlebells, and barbells), may further optimize performance outcomes. This study highlights the potential of differential training methods to address the multidirectional and dynamic demands of youth basketball. Future research should explore refined protocols and their long-term impact on athletic performance and retention.
