To compare immediate effect of static and dynamic stretching on sprint and jump performance in healthy school children

Abstract

The aims of this study were to compare the immediate effects of stretching static and dynamic stretching on sprinting and vertical jump performance of healthy school children. Ninety healthy school children (mean age = 11 yrs, range8–15 yrs) were randomly assigned into three groups: Static(SS), Dynamic (DS) and control group(NS) pre- and post-treatment immediately tests were performed to examine the effects of stretching on 10 m sprint run(10SR), Sargent vertical jump test (VJH). Following the warm-up period, subjects immediately began their stretching program. Subjects performed 5 sets of static (30 sec on alternate leg 2 repetitions) in (SS) and dynamic stretching (20 sec on alternate leg 10 repetitions) in (DS); in the control condition they do not performed stretching. Results from one way ANOVA revealed a significant difference on 10m sprint test (p<0.0307). Static stretching hindered 10SR and VJH by 1.07% and 1.3% respectively, Dynamic stretching improved 10SR and VMJ by 6.7% and 1.31% respectively, in control group 10SR and VMJ hindered by 4.5% and 4.55% respectively. In conclusion, the use of dynamic stretching is preferable for its immediate effect on jumping and sprint performance in healthy school children.
