Abstract
In this study, the in vivo force-velocity relationship was estimated at the tendon level, comparing triceps brachii muscles (TB) with biceps brachii muscles (BB). Fifteen male students (21.2±1.4yr.) performed elbow flexion and extension using a modified Wilkie's ergometer with various loads as a % of isometric force (Fmax). In the tendon force-tendon velocity relationship between the muscles, TB showed significantly greater V' than BB (TB>BB) under the same relative loads. Also, the tendon force was greater TB than BB. These results suggest that tendon force-tendon velocity relationships in the flexor and extensor of the elbow may be to reflect more the architecture of skeletal muscles than the muscle fiber composition.
