Exploration of the Optimal Riding Seat Position of Recumbent Exercise Bikes

This study used recumbent exercise bikes as the target of investigation and adopted the subjective comfort leveland fatigue level assessment resultsfor users to determine the optimal riding seat position for recumbent exercise bikes. The results showed that: (1) the ridingcomfort levels of the participants and the fatigue levels of their body parts at different seat positions are significantly different; (2) the shank, knee and thigh are the body parts with higher fatigue levels, and the effects of the seat position on the fatigue level and comfort level of the above body parts are significantly greater; (3)by using regression analysis, the optimal seat position for the user with various lower bodylengthswhen riding was derived as follows: seat center position from the crankshaft center (horizontal distance; mm) is equal to 269.15+3.50×lower bodylength (cm), and seat center position fromthe crankshaft center (vertical distance; mm) is equal to 58.58+0.71×lower body length (cm).

本研究以斜躺式健身車為探究對象，期藉由騎乘者實際騎乘後的主觀舒適度及各身體部位之疲勞度之評量結果，據以找出騎乘者最適騎乘的座椅位置。結果顯示：（1）不同座椅位置下受測者的騎乘舒適度及各身體部位之疲勞度達顯著差異；（2）各身體部位中以小腿、膝蓋及大腿是騎乘疲勞度較高之部位，且騎乘座椅位置對上述部位之疲勞度及舒適度之影響明顯較大；（3）經由迴歸分析推導出不同下半身長度之使用者之適合騎乘的座椅位置分別為：座椅中心點位置距曲柄軸中心之水平距離（mm）=269.15+3.50*下半身長度（cm），座椅中心點位置距曲柄軸中心之垂直距離（mm）=58.58+0.71*下半身長度（cm）。
