Cheerleader Positional Differences In Balance Performance While Wearing New And Old Cheer Shoes

Abstract

Unilateral stance on the dominant, and non-dominant limb on the force plate, and foam pad. The average sway velocity (VEL) and root-mean-square (RMS) of the center of pressure was used to quantify balance in the anterior-posterior (AP) and medial-lateral (ML) directions. Paired samples t-tests were used to analyze the results, with an alpha level of 0.05, and cohen's d was reported as a measure of effect size. RESULTS: Analyses revealed no statistically significant differences for balance measures between footwear (all p > 0.05). However, results suggest moderate effect sizes in the non-dominant foam pad condition for APRMS (d = 0.58) and MLRMS (d = 0.48) suggesting balance decrements in the new shoes. CONCLUSIONS: While not statistically significant, findings may suggest balance decrements in the new cheer shoes. These findings may be due to the novel aspect of the new shoes compared to the older shoes the participants may be more familiar with. Because of the novelty of the new shoes participants may have attempted to rely more on proprioceptive input during balance compared to the old shoes. If participants relied more on proprioceptive information on the unstable foam pad surface that may partially explain the increased postural sway. Future research should examine varying ages of shoes to potentially identify when cheer footwear begins to break down and cause balance decrements.
