摘要

騎乘自行車時的姿勢和舒適性有著密切的關係；騎乘姿勢與個人的身材特性與車種尺寸有關。本研究目的在探討自行車的把手與坐墊高度對於騎乘舒適度的影響。受試者為20位成年人(男女各半)，平均年齡24.6歲(SD=0.1)，在九種不同騎乘姿勢(三種把手高度*三種坐墊高度)下，收集其心搏率(heart rate)、把手與坐墊接觸力量與手部和臀部位移、身體各部位關節角度，以及主觀舒適度評量表。
實驗結果顯示，騎乘姿勢為自選把手和坐墊高度，有較低的主觀不舒適。此時軀幹角度趨近於38度性別差異會影響男性受試者的臀部與手部力量，顯著的大於女性。110%自選座墊高度會大幅的增加髖關節的外展角度與手腕力量，因此不舒適性增加。
110%坐墊自選高度造成臀部位移的距離較大，而在手部位移較無明顯。手腕在組合F(90%把手自選高度與110%坐墊自選高度)時手腕上的力量為6.1kg，而臀部在組合I(110%把手自選高度與90%坐墊自選高度)時，臀部上的力量高達16.8kg，主觀不舒適度都顯著的較高。

Bicycle riding posture and comfort are closely related; riding posture is related to personal characteristics and size of the vehicles. This study was aimsd at exploring the effects of the bike''s handle and seat height on riding comfort. Twenty adults (10 men and 10 women) with mean age 24.6 years (SD=0.1) were asked to perform 9 cycling tests in 9 different riding postures (3 handle heights *3 seat height). The heart rate, contact pressure on the handle and seat, displacement of hand and buttock, joint angles and subjective ratings of body comfort were collected.
The experimental results showed that the posture of free-choice handle and seat height had less uncomfortable feeling. This posture had about 38° in the upper body. The male participants had significantly greater strength on the buttock and the hand than the female. The 110% choice seat height could increased the adduction angle in the hip joint and the strength of hand ,resulting in more uncomfortable raings.
110% free-choice seat height had more displacement of buttock, but had no significantly more. The strength of the wrist is 6.1kg on wrist in combination F (90% height and 110% hand-demand choice seat height) and the hip of the strength of up to 16.8kg on combination I (110% hand-demand choice seat height and 90% height), ,subjective comfort are not significantly higher.
