| Summary: | <p>Dynamic warm-up is pre-exercise event which helps to prevent muscle cramp or injury due to over extension. However, the intensities used during dynamic warm up session can be manipulated using weighted vest. Hence, this study was conducted to determine the effects of dynamic warm-up protocol with three different loading schemes on speed and power performance among female varsity athletes. Forty female university athletes, age between 20-21 years old were recruited randomly. Participants were asked to perform general warm up before dynamic warm up with three different loadings; i) wearing weighted vest with 6% body weight (DV6), ii) wearing weighted vest with 12% body weight (DV12) and iii) not wearing weighted vest (D) in random order. Then participant were asked to perform vertical jump (VJ), standing broad jump (SBJ), and seated medicine ball toss (SMBT) and 20m sprint to measure the speed and power performance. The score were recorded and the data were analyzed using One-Way Repeated Measure Analysis of Variances (ANOVA). The result showed that there were significant difference of speed and power performance score when performing dynamic warm up with and without weighted vest (p<0.05). VJ, SBJ, 20m sprint test and SMBT showed a significant difference when compare DV12 and DV6 to D, with F(2,38)=18.39; F(2,38)=24.2; F(1.03,40.32)=1.83, and F (2, 38)=51.25,when p<0.05. There were no significant difference between DV6 and DV12 in all test except SMBT where p>0.05. As a conclusion, manipulating the intensity during dynamic warm up helps to improve speed and power performance especially when weighted vest with 12% body weight were used. In this research, vertical jump (VJ), standing broad jump (SBJ), seated medicine ball toss (SMBT) and 20m sprint performance enhanced about 8% , 6%, 10% and 5% after DV12, as compared with D. As implication of the study, weighted vest was proved to help the athletes and coaches as a part of their strategies to improve power and speed performance as the result showed the improvement beyond the intensity load.</p> |
