Abstract
Objective: To investigate the effects of eccentric hamstring training on strength measures and vertical jumping performance.
Methods: 26 male basketball players aged 10–12 were divided into Nordic Hamstring Strength Training group (N=15) and control group (N=11). Training was conducted over a 5-week period during which both groups participated in basketball training. All participants underwent pre- and post-training testing comprising isokinetic concentric and eccentric knee extension and flexion strength and vertical jump performance.
Results: The NHST group exhibited significant increase in eccentric hamstring strength (p< 0.05) and vertical jumping ability (p< 0.01) whereas the performance of the control group remained unchanged during that period.
Conclusion: Including eccentric exercises into entire training program improve muscular strength and can help athletes to reach their highest potential so they produce greater muscular forces.
