Title: Effect of Core Strength on the Measure of Power in the Extremities
Authors: Shinkle, Justin
Issue Date: 16-Mar-2011
Abstract: The purpose of this study was to determine the effects of core strength on the transfer and production of forces in the extremities. Twenty-five division 1 collegiate football players performed a series of medicine ball throws in the forward, reverse, right and left directions in a static and dynamic position. The results of the medicine ball throws were compared to several athletic performance measurements including: push press power, 1RM squat, 1RM bench press, countermovement vertical jump, broad jump, 40 yard dash, 20 yard dash, pro agility to the right and left, and the L drill. Several strong correlations were found in both the static and dynamic medicine ball throw positions when compared to the performance measures. Static reverse correlated with vertical jump (CMJ) (r=0.44), broad jump (BRD)(r=0.5) and push press power (PWR)(r=0.46). Static left (StL) and static right (StRi) correlated with PWR (r=0.59), (r=0.65) respectively, and Vel (r=0.52)(r=0.6), respectively. Fewer dynamic throws correlated significantly with the performance variables. Dynamic left (DyL) and Dynamic right (DyRi) correlated with PWR (r=0.53), (r=0.63) respectively, and Vel (r=0.55),(r=0.61) respectively. Dynamic forward (DyFw) correlated with the 1RM squat (r=0.45). A stepwise regression for push press power prediction reveals that 1RM squat is the best predictor of push press power. The results indicate that core strength does have a significant effect on the ability of an athlete to create and transfer forces in the extremities.
