Cover Story: While some information is known about the physiological determinants of performance in CrossFit, little is known about these determinants without the influence of CrossFit experience. This study examined the predictive value of aerobic fitness, total body strength, and body composition on performance in two distinct, standardized CrossFit workouts in 22 CrossFit-naive individuals. We found that total body strength predicted performance in a time-scored workout involving weightlifting, while absolute VO2 peak predicted performance in a longer workout scored by total repetitions completed. These results reveal the physiological complexity of training for a sport like CrossFit, and the distinct factors that influence performance in specific CrossFit workouts. View this paper
