- Abstract
The purpose of this study was to determine the effectiveness of different warm-up protocols on the flexibility and jumping performance in boys (13 - 14 yr). Twenty participants (49.7 ± 9.7 kg; 162.2 ± 10.7 cm) who have been taking basketball classes completed 4 different warm-up protocols. The participants performed each warm-up protocol on nonconsecutive days, and the order in which the protocols were performed was randomized. Each warm-up protocol consisted of a 5-minute moderate- intensity jog followed by either: no stretching (NS), static stretching (SS) dynamic exercises (DY1), or dynamic exercises plus 5 drop jumps from 30-cm boxes (DY2). The results indicated that dynamic warm-up protocols resulted in a significantly greater jumping performance than static stretching conditions. The vertical jump performance was significantly greater after DY1 (38.8 ± 8.0cm) and DY2 (36.6 ± 8.3cm) compared to SS (34.9 ± 7.7cm), and the long jump performance was significantly greater after DY1 (206.7 ± 33.9cm) and DY2 (199.5 ± 35.5cm) compared to SS (187.7 ± 30.5cm). No significant differences between DY1, DY2 and SS were observed for flexibility performance. These findings indicated that moderate-intensity dynamic exercises may be the most effective warm-up protocol for enhancing jumping performance in boys.
