中文摘要

本研究目的在於探討前腳掌在不同足背屈角度下對C艇選手下肢關節角度變化、關節活動度、划槳距離及划槳作用力之影響,並比較前腳的脛前肌、腓腸肌、股直肌、股二頭肌肌肉活性之差異。受試對象為臺北市立體育學院水上運動學系C艇專長的五名選手,隨機分別以前腳平踏0°、足背屈5°、10°、15°、20°等五種角度進行15秒鐘全力衝刺划槳;以motion analysis system(100Hz)擷取前腳下肢的踝、膝、髖關節的活動角度,將張力計裝置測功儀上收集划槳的動力輸出,並利用Biovision表面肌電儀(1,000Hz)收集前腳下肢肌群的肌肉活性。結果顯示雖然划槳距離不會因為足背屈的角度變大而減短,但前腳腳踏板為20°時有較大的踝與膝關節的活動範圍;10°時有較大的划槳力量峰值;脛前肌、腓腸肌與股二頭肌在前腳踏板角度小時有較大的肌肉活性,股四頭肌則是在前腳踏板角度大時有較大的肌肉活性。因此,本研究認為C艇選手划槳時,前腳應將原有的平踏0°改為約10°-20°,以改變下肢關節活動度與肌群收縮模式,進而促使較佳的划槳表現。

英文摘要

This study investigated the effects of the plantar flexion angle of the front foot on the joint angle of the lower extremity, the range of motion, the stroke distance, the stroke force, as well as the muscle activities of the tibialis anterior, gastrocnemius, quadriceps, and biceps femoris. Five Canadian canoe athletes were recruited from Taipei Physical Education College as the participants for this study. All subjects conducted a 15-second stroke with the maximum effort under the angle of the front foot at 0° 5°, 10°, 15°, and 20°, respectively. Ten cameras with the 100 Hz of motion analysis system, a load cell, and the surface EMG electrodes were used to collect the kinematics, kinetics and muscle activity parameters. The results revealed that the knee and ankle joints had a bigger range of motion at 20°. The stroke distance only slightly changed with the increasing plantar flexion angle. The peak stroke force lowered to 10°. The mEMG of quadriceps increased and muscle activities of other muscle groups decreased, when the front foot of the plantar flexion angle was bigger. The finding of this study suggested that the canoe athletes could get a good stroke performance through changing the range of motion and the pattern of muscle contraction of the lower extremity, which resulted from the front foot of the change of the plantar flexion angle.
