Table 1 Between sex results (mean ± SD, lower and upper limits for 95% confidence interval, CI) for iSLR measures of hamstring extensibility (leg° max ), passive stiffness (Me max , Me grad ), and stretch tolerance (hamstring VAS;mm)

From: Lower hamstring extensibility in men compared to women is explained by differences in stretch tolerance

Variable Men (n = 45) Women (n = 45) p-value
Mean ± SD 95% CI Mean ± SD 95% CI
leg° max (°) 79.4 ± 17.8 73.5 to 85.4 89.4 ± 12.4 85.2 to 93.5 0.003
Me max (Nm) 43.6 ± 23.6 35.7 to 51.5 40.3 ± 14.6 35.4 to 45.1 0.42
Me grad (Nm.° -1 ) 0.47 ± 0.15 0.42 to 0.53 0.38 ± 0.21 0.32 to 0.46 0.025
Hamstring VAS (mm) 41 ± 26 32 to 49 24 ± 19 18 to 30 0.001
  1. Between-sex differences were observed for leg°max, Megrad, and VAS (t-test p-values presented in table).
