COMPOUND TRAINING: A STUDY ON THE INFLUENCE ON THE BOUNCING FORCE OF VOLLEYBALL PLAYERS WHEN THEY JUMP AND SPIKE THE BALL

Abstract

Objective: This paper aims to investigate the impact of compound training (CT) on the jumping spike performance of volleyball players. Methods: Twenty athletes were randomly assigned to either the CT group or the resistance training (RT) group. After eight weeks of training, the results for in-situ jump and reach, run-up jump and reach, as well as squat jump (SJ), counter-movement jump (CMJ), and run-up jump measured using the Just Jump test system were compared between the two groups. Results: Prior to the experiment, there were no significant differences in any of the test parameters between the two groups ([Formula: see text]). Following the experiment, the one-repetition maximum (1RM) weighted deep squat result for the CT group was [Formula: see text][Formula: see text]kg, the in-situ jump and reach height was [Formula: see text][Formula: see text]m, and the run-up jump and reach height was [Formula: see text][Formula: see text]m, all with [Formula: see text] compared to pre-experiment values and the RT group. Additionally, the duration and height of flight of SJ in the CT group were [Formula: see text][Formula: see text]s and [Formula: see text][Formula: see text]cm, respectively; the duration and height of flight of CMJ were [Formula: see text][Formula: see text]s and [Formula: see text][Formula: see text]cm, respectively; the duration and height of flight of run-up jumps were [Formula: see text][Formula: see text]s and [Formula: see text][Formula: see text]cm, respectively. All of the above results were significantly higher than those before the experiment and those of the RT group ([Formula: see text]). Conclusion: The superior results observed in the CT group’s jumping tests suggest that the effects of CT on bouncing force are more pronounced, making it a viable approach for practical training.
