其他摘要：Team Volleyball requires not only technical and tactical skills but also great deal of physical fitness. The aim of this study was to investigate the changes in physical parameters produced during an in-season resistance training (RT) program and detraining phase in 12 top TVP competing in the elite Portuguese league. Moreover, differences in the adaptive responses between players who played most of the times (starters: S) and players that were mainly used as substitutes (non starters: NS) were analysed. Twelve elite healthy male TVP voluntarily participated to the study. We monitored the squad throughout a 12-week competitive in-season consisting of 14 games using a longitudinal study design. Apart from normal technical/tactical practice sessions (2-3 hours per day) and weekend competitions, all underwent 12 weeks of RT program. Upper and lower body maximal dynamic strength, jump and ball throw distance were tested at three intervals: before the experimental period (T1) and after the 12-week experimental period (T12). Of the grate interest of this research was the lack of any interactions for group (S or NS) by time effects for any of the tests, except for bench press. Here, S demonstrated superior upper body strength values after 12 weeks (p=0.025), indicating that both groups responded similarly to the training program. The combination of a RT and volleyball training resulted in larger improvements in both groups. Thus, while no differences appear to exist in performance between starters and non-starters, it was shown that most performance variables for ST and NS can be improved with a comprehensive strength and conditioning program for top volleyball players.
