Abstract

INTRODUCTION: The sport of cheerleading requires that athletes perform with a high degree of flexibility, strength, endurance, and balance. The leading injury in cheerleading is a lateral, inversion, ankle sprain. As footwear serves as an interface between the foot and the surrounding environment, characteristics of shoes should be monitored to determine the effects on proprioceptive communication. No previous literature was found that examined the biomechanical differences between “Old” and “New” shoes in collegiate cheerleaders. PURPOSE: The purpose of this study was to examine the biomechanical differences exhibited by collegiate cheerleaders while performing balance testing and step-down, landing tasks in “old” and “new” cheer shoes. METHODS: Participants included 5 male and 20 female collegiate cheerleaders (19.88 ± 1.36 years; 61.94 ± 9.33 kg; 162.70 ± 6.68 cm). Sixteen anatomical retroreflective markers were placed on each participants’ lower extremities. Participants completed randomized trials of ten balance conditions as well as step-down tasks consisting of a leveled and a tilted platform. Data collected from two days of testing was used for analysis. RESULTS: Analyses revealed no statistical significance for postural sway measures between “Old” and “New” shoes (p>.05). Analyses revealed a statistically significant interaction between shoe and condition when examining the ankle joint angle during step-down tasks (F(1,24)=12.070, p=.002). Further investigation revealed main effects of both shoe (F(1,24)=85.541, p
