Abstract

The purpose of the study was to investigate the acute effect of different types of combined training movements on jump height, power and neuromuscular activation of vertical jump. Sixteen Division I collegiate volleyball players (height: 179.9 ± 9.24 cm, weight: 76.2 ± 11.65 kg) from the Chinese Culture University were participated in this study. Every subject received different treatment on each day by a counterbalanced design. The treatments included, weight training movement followed by plyometric training movement (W + P), plyometric training movement followed by weight training movement (P + W), weighted plyometric training movement (WPT), weight training movement (W), plyometric training movement (P) and unweighted (U). Within 4-min post-movement, jump height and power were measured by using NewTest-300. Synchronized neuromuscular EMG activities of vastus lateralis, vastus rectus and vastus medialis were recorded by Noraxon wireless EMG system. Motor unit recruitment was estimated by using the mean and peak of root mean squares of EMG (EMGrms). Data were analyzed by using one-way ANOVA with repeated measures. The results were shown as follows: 1. Jump height and power of weighted plyometric training movement was significantly higher than un-weighted (WPT: 57.0 ± 8.155 cm, 4,825.8 ± 381.5 Watt > U: 54.8 ± 7.67 cm, 4,692.6 ± 296.35 Watt; p < .05). The jump height of plyometric training movement was significantly higher than weight training movement followed by plyometric training movement, plyometric training movement followed by weight training movement and un-weighted (P: 57.8 ± 7.68 > W + P: 55.6 ± 7.52, P + W: 55.5 ± 9.38, U: 54.8 ± 7.67 cm; p < .05). 2. Peak EMG activities in vastus medialis after weight training movement followed by plyometric training movement, weight training movement and plyometric training movement were significantly higher than plyometric training movement followed by weight training movement (W + P: 178.4 ± 77.53, W: 174.8 ± 64.97, P: 197.1 ± 94.7 > P + W: 144.8 ± 61.32%; p < .05), and the peak EMG in quadriceps after plyometric training movement and unweighted group were significantly higher than plyometric training movement followed by weight training movement (P: 155.3 ± 41.77, U: 165.3 ± 52.54 > P + W: 129.6 ± 41.12%; p < .05). These results concluded that weighted plyometric training movement can promote the acute jumping ability and power. It is recommended that weighted plyometric training movement could be implementing before practice or competitions.
