Abstract

The aim of this study was to determine the acute effects of static stretching and dynamic warm-up exercises on vertical jump performance. Sixty-four children (mean age 13.3 ± 0.5 years) were assigned randomly to 3 different warm-up routines on non-consecutive days. The warm-up methods used were 5 minutes of jogging and 5 minutes of static stretching (SS), 5 minutes of jogging and 10 minutes of dynamic exercises (DYN), and finally only 5 minutes of jogging as the control (NS). After each warm-up session, all the children were made to undertake a vertical jump test. Data were analysed using repeated measures analyses of variance (ANOVA), and a statistically significant difference between the NS, SS and DYN groups with regards to vertical jump performance was established (p<0.05). Based on these results, static stretching performed after aerobic exercises of mild intensity was found to hinder vertical jump performance, while dynamic warm-up was found to have a positive effect.
