Description
Summary:The purpose of this study was to investigate the role of physical fitness on the FRAN CrossFit® workout time-trial. Twenty male athletes were divided into a fast group (FG) and a slow group (SG) according to the median value of the FRAN time-trial. Measurements included the FRAN time-trial, body composition analysis, isometric handgrip and isometric mid-thigh pull strength, countermovement jump (CMJ), 30 s continuous jumping test (CJ30), and one repetition maximum (1-RM) strength in the squat, thrusters, snatch, clean and jerk, and dead-lift. The FG had significantly lower body fat (p < 0.018), higher CMJ (p < 0.05), lower percentage decrement in CJ30 height (p = 0.023), and higher 1-RM strength (p < 0.05) compared to the SG. A significant correlation was found between the FRAN time-trial with percentage body fat (r = 0.512, p = 0.021) and with percentage decrement in CJ30 height (r = 0.454, p = 0.044). Performance in the FRAN time-trial was also correlated with CMJ variables (r ranged from 0.634 to 0.663, p < 0.05) and 1-RM strength (r ranged from 0.510 to 0.701, p < 0.05). These results suggest that the FG has a higher tolerance to fatigue and is stronger, more powerful, and has less body fat compared to the SG. Consequently, body fat, 1-RM strength, power, and anaerobic capacity may predict the FRAN time-trial in CrossFit® athletes.
