Summary:ABSTRACTFitzgerald, JS, Peterson, BJ, Warpeha, JM, Johnson, SC, and Ingraham, SJ. Association between vitamin D status and maximal-intensity exercise performance in junior and collegiate hockey players. J Strength Cond Res 29(9)2513–2521, 2015—Recent evidence suggests that athletes are at risk for poor vitamin D status. This study used a cross-sectional design to investigate the strength of association between 25-hydroxyvitamin D (25(OH)D) concentration and measures of maximal-intensity exercise performance in competitive hockey players. Fifty-three collegiate and junior male ice hockey players training near Minneapolis, MN (44.9° N latitude) participated in the study during the off-season (May 16–June 28). Circulating 25(OH)D concentration, grip strength, vertical jump performance, and power production during the Wingate Anaerobic Test (WAnT) were evaluated. Despite no athletes with 25(OH)D concentration indicative of deficiency (
