Abstract
The purpose of this study is to examine the effects of ankle fixation during pedaling to learn the skill to develop the performance of cycling. Three experiments were conducted to measure the cycling performance under the condition of the settled power (250W), the effects of ankle movement under the fixed crank position, and the maximum power in the maximum effort for 10 seconds. The results that effects of ankle fixation are as follows; 1) Joint power slightly increased in hip and decrease in knee, although there was no significance. 2) Joint torque was not changed in knee and hip. 3) Angular velocity significantly increased in both flexion and extension of hip across all trials, and significantly decreased in extension of knee. 4) Maximum power tended to slightly decrease but not significant. These results suggests that the ankle fixation is useful technique to learn the effective pattern of joint movement, because the change of angular velocity by ankle fixation leads the change of joint power and promotes activities of hip movement during pedaling. But it was also indicated that this technique did not improve the maximum power directly.
