Cabre HE, Schuster JG, Hickner RC, Chow GM, Shelton A, Ormsbee MJ. Characterization of the Relationship Between Workload and Collegiate Track and Field Performances: A Pilot Study. JEPonline 2021;24(5):48-57. This study determined the relationship between the acute:chronic workload ratio (ACWR) and the 100 m and the 200 m race time performances. Season long retrospective analysis was used to evaluate the ACWR via Session-Rate of Perceived Exertion (sRPE) among seven division 1 NCAA collegiate track and field sprinters. Pearson correlations were used to characterize the relationship between average best time and the average acute:chronic workload ratio (aACWR). Secondarily, explanatory variance was assessed by squaring the Pearson correlation between the aACWR and the average 100 m and the 200 m best times. Positive correlations between the aACWR and the average 200 m best time (r = 0.765; P = 0.235) were observed. The aACWR explained 8.76% of the variance in the 100 m race times and 58.52% of the variance in the 200 m race times. The ACWR using sRPE may be a useful measure for evaluating performance in Track and Field. Key Words: Athletics, Peak Performance, Sprinters
INTRODUCTION Positive physiological adaptations are stimulated by progressive exercise loads over the training period that have a direct and subsequent impact on athletic performance (1,9). In modern sport, techniques for [...]
