AB  - This study aimed to evaluate changes in pre- to postseason power output, fatigue, 
      and recovery during a repeated sprint test. Twenty National Collegiate Athletic 
      Association Division I men's hockey athletes performed identical sessions of 
      repeated sprint work pre- and postseason. The repeated sprint test consisted of 5 
      sets of 45 seconds of repeated sprint work with 90 seconds of rest in between 
      each series of sprints. Power output (W), decrement, and recovery scores (RECs) 
      were determined using raw data from a nonmotorized treadmill. Ratings of 
      perceived exertion were recorded after, and perceived readiness (PR) recorded 
      before, each series of sprints. Mean power was significantly higher in preseason 
      vs. postseason performance during sprint 1 (760.6 vs. 691.3 W; p = 0.03), sprint 
      2 (719.9 vs 657.0 W; p = 0.05), sprint 4 (648.4 vs 588.9 W; p = 0.04), and sprint 
      5 (656.6 vs. 586.8 W, p = 0.04). Ratings of perceived exertion were significantly 
      higher during sprints 3, 4, and 5 postseason with PR significantly higher 
      (indicating less readiness) before sprints 3 and 4. There were no significant 
      differences in REC or decrement score. Overall, athletes were unable to maintain 
      power during subsequent repeated sprint work during postseason. The degree to 
      which the athletes fatigued and recovered between sprints did not change between 
      pre- and postseason testing, however, athletes exhibit increased perceptual 
      strain during the repeated sprint work. These data indicate meaningful 
      performance and perceptual differences throughout the competitive season in 
      collegiate-level hockey players.
