Effects of Training in Strength Shoes on 40,Yard Dash Time, Jumping Ability, and Calf Girth

Abstract

This Study was done to determine the effectiveness of training in Strength Shoes. Seventy-two college-age men were randomized into either a control group (CG), a Strength Shoe group (SSG), or regular shoe group (RSG). SSG and RSG trained 3 times a week for 10 weeks and followed identical programs as prescribed by the manufacturer. SSG wore the Strength Shoe while RSG wore their own shoes. All subjects were pre- and posttested for 40-yd dash time, vertical jump, standing broad jump, and right and left calf girth. Of the 72 subjects, 52 completed the study: 22 CG, 14 SSG, and 16 RSG. Seven SSG and 1 RSG dropped out due to injury. Repeated measures ANOVA revealed that SSG had significant increases in girth, but these changes were not significantly different from either CG or RSG. There were no within- or between-group differences for the other variables as a result of training. These results indicate there was a tendency for the type of training used in the present study to improve performance; however, these improvements were independent of the type of shoe worn in training. Additionally, undergoing this type of training in Strength Shoes resulted in an increased rate of injury compared to training in regular athletic shoes.
