ACUTE EFFECTS OF WARM-UP COMBINED WITH DYNAMIC STRETCHING ON VERTICAL JUMP, SPRINT AND AGILITY IN YOUNG MALE SOCCER PLAYERS

The objective of this study was to investigate the acute effect of warm up combined with dynamic stretching on vertical jump, sprint and agility performance. Eighteen young male soccer players (age: 16.72 ± 0.22 years; height: 172.50 ± 1.49 cm; weight: 67.16 ± 3.00 kg) performed 2 warm-up conditions:  warm-up alone (WU) and warm-up with dynamic stretching (WU+DS) in a counterbalance sequence, on the different day, interspersed by a minimum of 48 hours of rest.  Warm-up was preceded by a 600 meter jogging. Dynamic stretching comprised of butt kicks, high-knee run, hip rolls, calf raise, straight march and kick back swing. Each movement was carried out 12 times for 2 sets with frequency 60 beats/min. Vertical jump, 20-m sprint time and agility time were measured following each intervention. Results revealed that young male soccer players performed a superior performance of vertical jump, sprint and agility in the WU+DS condition compared to the WU condition. Thus, the dynamic stretching play a potential role in enhancing the performance of young male soccer payers.
