A comparison of a standard warm-up model and a dynamic warm-up model on flexibility, strength, vertical jump height, and vertical jump power

Objective. To compare the acute effects of a dynamic warm up and standard warm up on hamstring, quadriceps, and hip flexor flexibility, quadriceps and hamstring strength, and vertical jump height and power. Design and setting. An experimental research design was used to compare a standard warm up (n=15), a dynamic warm up (n=15), and a control group (n=15) on acute changes after a single bout of warm up. Subjects. Forty-five physically active recreational soccer players (age = 22.13 +/- 2.77 years, ht = 68.47 +/- 3.77 in, wt = 73.59 +/- 14.53 kg) volunteered to participate. Measurements. Flexibility, strength, vertical jump height, and vertical jump power were evaluated. A mixed model analysis of variance was used for statistical analyses. Results. The dynamic warm up significantly increased hamstring flexibility from pre test measures (p < 0.0001) and significantly increased eccentric quadriceps peak torque (p = 0.012). Furthermore, a trend indicated that the dynamic warm up increased concentric quadriceps peak torque from pre to post-test measures. No other variables were significantly impacted by any warm up group. Conclusion. Our results suggest that an acute bout of a dynamic warm up improves hamstring flexibility and eccentric quadriceps strength. Future research should investigate the effects of a dynamic warm up on reducing muscular injury rates.
