Abstract
INTRODUCTION: lumbo-sacral posture and the sit-andreach score have been proposed as measures of hamstring extensibility. However, the validity is influenced by sample characteristics. OBJECTIVE: to determine the validity of lumbo-horizontal angle and score in the sit-and-reach test as measures of hamstring extensibility in older women. METHOD: a hundred and twenty older women performed the straight leg raise test with both leg, and the sit-and-reach test (SR) in a random order. For the sitand- reach test, the score and the lumbo-sacral posture in bending (lumbo-horizontal angle, L-Hfx) were measured. RESULTS AND DISCUSSION: the mean values of straight leg raise in left and right leg were 81.70 ± 13.83º and 82.10 ± 14.36º, respectively. The mean value of EPR of both legs was 81.90 ± 12.70º. The mean values of SR score and L-Hfx were -1.54 ± 8.09 cm and 91.08º ± 9.32º, respectively. The correlation values between the mean straight leg raise test with respect to lumbo-sacral posture and SR score were moderate (L-Hfx: r = -0.72, p < 0.01; SR: r = 0.70, p < 0.01). Both variables independently explained about 50% of the variance (L-Hfx: R2 = 0.52, p < 0,001; SR: R2 = 0.49, p < 0,001). CONCLUSIONS: the validity of lumbo-sacral posture in bending as measure of hamstring muscle extensibility on older women is moderate, with similar values than SR score.
