Relationship Between Individual and Composite FMS™ Scores with the Anthropometric and Physical Characteristics of Elite Touch (Rugby) Players

Abstract

Purpose

To describe and compare the movement patterns, anthropometric and physical characteristics of male and female Touch players; and examine the relationships between Functional Movement Screening (FMS^™) scores and the anthropometric and physical characteristics.

Methods

This was a cross-sectional study with 35 elite Touch players (18 males, age = 24.7 ± 4.9 years; 17 females, age = 26.7 ± 5.2 years). Anthropometric (stature, body mass) and physical characteristics (sprint times, glycolytic change-of-direction test, and countermovement jump (CMJ) flight time and peak power) were assessed alongside movement patterns using the FMS^™ battery. Data were analysed for between-sex differences (independent t-test, Mann–Whitney U) and relationships (Spearman’s correlation coefficient).

Results

Between-sex differences in body mass (t = 6.082, P < 0.001), stature (t = 9.247, P < 0.001), CMJ flight time (t = 3.576, P = 0.001), relative CMJ peak power (t = 6.578, P < 0.001), 10 m sprint time (t = 15.861, P < 0.001), glycolytic change of direction test time (t = − 11.831, P < 0.001) and Yo–Yo IR1 (t = 6.842, P < 0.001) were observed. There were  minimal differences for deep squat (Z = − 1.036, P = 0.443), in-line lunge (Z = − 1.284, P = 0.303), shoulder mobility (Z = − 0.173, P = 0.883), trunk stability push-up (Z = − 0.896, P = 0.483) and rotary stability (Z = − 1.537, P = 0.273). The correlation between total and individual FMS^™ scores with anthropometric and physical characteristics ranged from trivial-to-moderate (r = − 0.502 to 0.488).

Conclusion

The lack of difference for the FMS^™ composite score and small-to-trivial differences in individual scores allows a comparison between mixed populations within Touch. Whilst many of the correlations were trivial-to-small, there were differences between sexes in the associations and evidence that improvements in functional deficiencies could translate into improved physical performance.
