Dynamic or Static Stretch to Increase 40-Yard Dash Speed
Abstract
The purpose of the study was to determine if there was a significant difference in the performance of subjects when they engaged in a dynamic stretching routine verses a static stretching routine prior to executing the 40-yard dash. A sample group of thirty-nine subjects, (20 males and 19 females) completed the study. Measurements were taken on two different days of the week. They performed the static stretching routine and prior to sprint on day 1, followed by a day of rest. On day 3 the dynamic stretching routine was performed prior to the sprints. The paired-samples t-test indicated that 40-yard dash scores were not significantly different between subjects undergoing a static stretch routine (M = 6.19 seconds, SD = .90) compared to subjects undergoing a dynamic stretch routine (M = 6.17 seconds, SD = .89), t(39) = .33, p =.74, p > .05, df = 38 Pearson's correlation was statistically significant, r(39) = .90, p < .05, indicating the presence of a strong statistically significant positive relationship between speed results after static and dynamic stretching routines. ANOVA results showed significant differences between males and females on 40-yard dash speeds following static stretching routines, F (1, 37) =11.83, p = .001, and dynamic stretching routines, R (1, 37) = 9.15, p .004. Following static stretching, males were faster (M = 5.76 seconds) than females (M = 6.64 seconds); likewise, following dynamic stretching, males were faster (M = 5.79 seconds) than females (M = 6.57 seconds). The study found there was not a significant difference in the 40-yard dash time of an individual after they performed static and dynamic stretching. This has implications for further study and review regarding impact of static or dynamic stretching routines on balance or reaction time.
