Abstract

Limited research exists examining the influence of age on the passive mechanical properties of the muscle-tendon unit. The purpose of the present study was to 1) investigate the age-related differences in maximum range of motion (MRoM), stretch tolerance (maximal tolerable torque), and the dissipation coefficient (DC), and 2) examine the influence of plantarflexor muscle size and quality on the age-related differences in the DC.
