Abstract
Context: The primary objective of this study was to examine the effects of a non-traditional lacrosse fall season on functional movement and stability in both male and female collegiate lacrosse athletes.
Methods: We recruited 50 male (age=19.38+1.24 years, height=182.63+6.16 cm, mass=82.37+8.46 kg) and 22 female (age=19.68+1.17 years, height=165.10+6.88 cm, mass=64.09+8.72 kg) volunteers from National Collegiate Athletic Association Division III lacrosse teams for the study. Independent variable was time (pre, post). Main outcome measures included pre- and postseason extremity measurements for the Y-Balance Test (YBT, reliability=0.67-0.96) as well as dorsiflexion (right, left) range of motion (ROM) via goniometer. Data files were split by sex then analyzed using a 1-way repeated measure ANOVA.
Results: Male YBT right leg scores improved significantly from preseason (mean=102.47+1.31) to postseason (mean=105.64±1.54; F1,49=11.78, P=0.001, ƞ2=0.19). Time significantly improved male left leg scores from preseason (mean=102.41+1.29) to postseason (mean=104.32+1.37; F1,49=5.08, P=0.029, ƞ2=0.09). Time significantly decreased male right dorsiflexion ROM from preseason (mean=34.36cm+1.09) to postseason (mean=30.26cm+0.90; F1,49=24.98, P2=0.34) as well as left dorsiflexion ROM from preseason (mean=34.70cm+0.85) to postseason (mean=30.34cm+0.74; F1,49=34.21, P2=0.41). No differences were found in lower extremity measurements for females (P>0.05)
Conclusion: Functional stability may change over the course of a season, resulting in a possible increased risk of injury later in season due to compensatory patterns, hypomobility or hypermobility or altered proprioception, balance and range of motion (ROM). Therefore, dorsiflexion ROM should be considered when developing in-season strength, conditioning and flexibility programs for male lacrosse athletes.
