Abstract
To investigate the effects of plyometric training on lower limb biomechanics and explosive power in male college basketball players, and to provide a theoretical basis for optimizing basketball-specific training.
Eighteen male college basketball players were selected and randomly divided into an experimental group (receiving plyometric training) and a control group (receiving traditional resistance training), with 9 participants in each group. Before and after the training, the kinetic indices of lower limb explosive power (including muscle RMS (root mean square) values, contribution rates, joint torque, and stiffness), kinematic indices (motion angles and angular velocities of the ankle, knee, and hip joints), and training indices (jumping performance and movement performance) were tested and analyzed in both groups.
After plyometric training, in terms of major lower limb muscle activation, the experimental group exhibited very significant differences (P<0.01) in RMS values of the rectus femoris, medial gastrocnemius, and lateral gastrocnemius compared with the control group; the RMS value of the long head of biceps femoris was lower than that of the control group, with a significant difference (P<0.05), and its contribution rate decreased by approximately 3.72%. At the joint stiffness level, lower limb stiffness in the experimental group increased significantly (P<0.05), with an increment of 6.4 BW/m; the maximum angle and maximum angular velocity of the ankle joint during the support phase both increased significantly (P<0.05). The experimental group demonstrated superior explosive power performance compared with the control group, with significant improvements (P<0.05) in standing long jump, stationary double-leg jump and reach, and running single-leg jump and reach; in terms of movement performance, the "T" test shuttle run and "V" dribble shuttle layup times improved by 1.09 s and 2.68 s respectively, both showing significant differences (P<0.05); there was no significant difference between groups in the 10-yard sprint (P>0.05).
This study demonstrates that plyometric training is more effective than traditional resistance training in improving lower limb explosive power in male college basketball players and is worthy of widespread promotion in basketball-specific training.
