Acute effect of different volume of dynamic stretching on vertical jump perfomance among university volleyball athletes/ Allan Ivan Mauming

The objective ofthis study was to assess the acute effect of different volumes of dynamic stretching on vertical jump performance which are the vertical jump height (cm), power (N) and force (W/kg). Twelve university volleyball male athletes (age 20.6 ± .515 years) were separated into two groups which are 6 minutes of dynamic stretching (n=6) group and double volume of dynamic stretching group (12 minutes; n=6). The dynamic stretching has 11 exercises focusing on the hip and thigh muscles. The vertical jump performance was measured by using the force-platform machine which can measure jump height (cm) jump power (N) and jump force (W/kg). Pre- test data were collected during familiarization session and post-test data were collected immediately after the intervention.
