Abstract
前言：自行車為一相當特殊的競技運動，不只在奧運中有許多不同項目的比賽(公路、越野、場地)，也是日常生活中相當普及的交通工具，而滾筒訓練台為選手訓練時常使用之工具，但就連選手初次使用訓練台都因其特殊的騎乘方式而無法馬上駕輕就熟於訓練台上保持平衡，而是什麼樣的因素會影響於訓練台上騎乘自行車的技能表現呢?本研究以操控不同工作限制的方式探討影響自行車於滾筒訓練台上騎乘之平衡與踩踏表現的因素。方法：召集八名受試者分別在不同目標速度與負荷量下於滾筒訓練台上騎乘動力曲柄自行車與一般自行車並將之技能表現量化，進行自行車騎乘技能表現之分析。結果: 影響自行車技能表現的因素除了目標速度外，負荷量於極端的目標速度下也會改變騎乘自行車於滾筒訓練台之技能表現，操弄負荷量與目標速度可以探討自行車技能表現。
Bicycle riding is a special activity. People not only compete in the many different bicycle events in the Olympics, but also ride the bicycle in daily life. Bicycle is an important vehicle for transportation. Roller bike trainer is regularly used for athletic training, but it takes some skill to balance on the bike when the athlete riding on it for the first time. what kind of factors that affect the riding performance on the roller bike trainer was the main purpose of this study. Method: Eight healthy males who have experience of riding on a roller bike trainer were recruited to ride the ordinary bicycle and the power crank bicycle in different velocity and inertial load on the roller bike trainer. Riding performance was analyzed with 2-way repeated measure ANOVA. Results: In addition to velocity, the extreme inertial load also affected the riding performance on the roller bike trainer.
