The purpose of this study was to determine the influence of sex and height on sit-and-reach (S&R) flexibility. Women (n=22, height =169.0±8.0 cm) and men (n=22, height =180.8±7.2 cm) were measured for standing height and standard S&R flexibility. Height was not significantly related to S&R in either men (r = -0.04) or women (r = 0.22). Multiple regression was used to estimate S&R from height and sex (R2 = 0.14, p = 0.04). Standardized beta coefficients from linear regression indicated that 94% of the variance for flexibility was accounted for by sex and 6% of the variance for flexibility was accounted for by height. Therefore, height per se is not a major factor in S&R flexibility. Further analysis might include other dimensions such as arm length and arm-to-leg length ratio to determine contributions to S&R flexibility.
