| Research Abstract |
To understand the motor control during standing, this study investigated the motor performance and muscle activities of lower limbs in healthy youths and elders by using the visually guided tracking task on the force platform. The motor performance was influenced by the movement direction, the amplitude and the velocity of the motor task. Especially, there was the U shape relation between the motor performance and the motor velocity, and the optimum motor velocity for the motor task was shown in both groups. Age differences were confirmed in muscle activities of knee flexors which were biarticular muscles. This suggested that the functional loss of biarticular muscles might narrow elder's range of choice for the postural strategy by aging.
