摘要：The purpose of this study was to examine the magnitude and direction of the effects of short-term CrossFit (CF) participation on measures of health and fitness. Six male participants completed 4 wks of CF training with outcomes assessed pre- and post-intervention. Statistical methods consisted of both traditional significance testing and evaluation of magnitude-based inferences. Beneficial effects are noted for the majority of the health and fitness parameters assessed. However, with negative perturbations in inflammatory status and mood states performance, these subjects may have reached a state of functional overreaching. With training intensity not monitored, continuous participation in CF may result in an overtrained individual. Moving forward, research on CF must investigate the utility of improved CF performance outside the gym and integrating appropriate monitoring strategies to improve participant recovery and adaptation while maintaining the integrity of the original programming philosophies.
