Assessing The Feasibility Of Pedometers For Quantifying The Volume Of Impacts During Varsity Athletic Practices

Abstract

The purpose of the current investigation was to test the feasibility of utilizing pedometer data collected during game-like practices to quantify the number of impacts experienced by varsity athletes. Forty-four varsity basketball and soccer athletes wore pedometers and the total number of steps and practice time were recorded during two different practices of similar intensity. The normalized step count, calculated as the total numbers of steps divided by the practice time, was obtained from the first practice and was used to estimate the step count for the second practice. The estimated step count was then compared to the actual step count, as determined from the pedometers. The mean percent difference between actual and estimated step counts was under 25% for approximately 75% of all athletes with no significant difference between the estimated and actual number of steps. The presented results suggest that the pedometer-based method presented here is a feasible method for estimating the number of steps experienced by university varsity athletes.
