Abstract

Male subjects (n = 220), ranging in age from 20 to 84 years, were administered three trials of the sit-and-reach (SR) and the modified sit-and- reach (MSR) tests. The MSR test incorporated a finger-to-box distance (FBD) to account for proportional differences between legs and arms. The FBD ranged from 15 to 37 centimeters, with a mean of 25 centimeters (± 4.3). The zero-order correlation between FBD and MSR was −0.06 (p > 0.05) and between FBD and SR was −0.40 (p 0.05), but a significant difference was found between the groups on SR performance (F = 16.4, p > 0.01). The results indicate that the MSR procedure eliminates concern about disproportionate limb length bias.
