Context: Lower extremity muscular strength may vary by different sport participation during growth process.
Objective: To investigate effect of sport participation and growth by comparing strength of the hamstrings, quadriceps, and hamstrings to quadriceps strength ratio (H:Q ratio) between young female figure skaters and soccer players.
Design: Cross-sectional.
Settings: Laboratory affiliated with regional sports medicine center.
Participants: pediatric and adolescent female athletes.
Procedures: Isometric hamstrings and quadriceps strength were measured.
Main outcome measures: Strength of the hamstrings, quadriceps, and hamstrings to quadriceps strength ratio (H:Q ratio).
Statistical analysis: Effect of sport participation and growth was analyzed through a two-way (two sports: figure skaters and soccer players; three age groups: <12 years, 13-16 years, and >17 years) analysis of covariance.
Results: Hamstrings strength was significantly greater in figure skaters than soccer players. Also, hamstring strength of 13-16 years and >17 years was higher compared to <12 years. Additionally, significantly higher H:Q ratio in figure skaters compared to soccer players.
Conclusions: There is effect of growth on hamstrings strength among 13-16 years and >17 years compared to <12 years. Figure skaters showed greater hamstrings strength and H:Q ratio than female soccer players.
