Rear-Foot Motion in Soccer Players with Excessive Pronation under 4 Experimental Conditions

Abstract

Context:Soccer is a sport that includes running in several different directions. For this reason, it is important for the shoe to control the motion of the foot.Objective:This study was undertaken to compare rear-foot motion in high school soccer players with excessive pronation under the experimental conditions of barefoot (BF), experimental shoe (ESS), experimental shoe with arch support (ESSAS), and the experimental shoe with pronated lacing technique (ESSPLT).Design:1 × 4 factorial.Setting:Biomechanics laboratory.Patients or Other Participants:20 male and female subjects with excessive pronation in both feet (N = 40) as determined by navicular height and arch index.Interventions:The subjects were filmed with a 2D Peak Performance video system as they ran a specified course. Rear-foot motion was determined by rear-foot angle measurements from the point of foot-fat to heel off.Main Outcomes Measures:There would be a difference with rear-foot motion between the three experimental conditions.Results:Results of the study indicated significant (P≤ .05) differences between the conditions of BF and ESS, BF and ESSAS, BF and ESSPLT, and ESS and ESSPLT.Conclusions:In the experimental conditions, the shoe with the pronated lacing technique was superior in its effectiveness to control rear-foot motion.
