Abstract

This study aimed to 1) assess the reliability of the FMS protocol and 2) to establish changes in both FMS and tests of physical performance throughout a season. The reliability of the FMS components (12 in total) was assessed via a non-parametric statistical approach, based on two trials, separated by one week. Score on the FMS, strength (3 RM full-squat, 1 RM bench press), running speed (10 & 40 m) and jump height of 12 elite male under-19 rugby league players was monitored at pre-, mid- and late-season periods. There was no bias (P > 0.05) found between trials for the FMS, with the majority of components reaching 100% ‘perfect agreement’, reflecting the good reliability of the FMS tool. There were no effects (P > 0.05) of season stage on any of the FMS components; however, an improvement (P < 0.05) between the pre- and both mid- and late-season periods was apparent in every component of fitness, such as 1 RM bench-press (112.92 ± 24.54 kg; 125.83 ± 21.41 kg; 125.98 ± 24.48 kg) and 40 m sprint time (5.69 ± 0.35 s; 5.62 ± 0.31 s; 5.64 ± 0.27 s). Our findings demonstrate that the FMS can be reliably administered to elite rugby league players but will not change in accordance with physical performance across a competitive season. Our findings should not necessarily deter practitioners from using the FMS but begin to question the specific qualities that are being assessed through its administration.
