Bilateral difference in hamstrings to quadriceps ratio in healthy males and females

摘要: Abstract Objective To compare the isometric and isokinetic hamstrings to quadriceps (H:Q) ratio 1) between dominant (D) non-dominant (ND) legs, 2) healthy males females. Design Cross-sectional. Setting University research laboratory. Quadriceps strength were assessed by maximum contractions at six angles (40°, 50°, 60°, 70°, 80°, 90°) concentric three angular velocities (60°s −1 , 180°s 300°s ). Participants Forty physically active adults (25 males). Main outcome measures Peak torques of hamstrings, corresponding H:Q ratios. Results Isometric increased with greater knee extension ( P Conclusions When setting rehabilitation goals, it may be appropriate adjust leg based on uninvolved consideration dominance. Gender-related differences do not explain discrepancy in literature regarding bilateral ratio. Other subject characteristics such as age training more relevant.
