不同騎乘姿勢對原地腳踏車運動攝氧量與肌電圖反應之影響

The Effects of Different Upper Body Positions on Oxygen Uptake and the Electromyographic Responses during Incremental Test on the Cycle Ergometer

摘要


This study compared the physiological responses and root mean square electromyography (rms EMG) in the upright position (UP), the drop position (DP) and the aero position (AP) during the incremental test on cycle ergometer. Twelve healthy males (aged 23.30±0.97 yrs; height 175.62±6.66cm; weight 72.63±7.32kg) completed these three incremental tests on different positions respectively by counter-balance design. During these tests, we assessed the physiological responses at 150W, 200W and exhaustion and compared normalized slope of rms EMG and oxygen uptake (VO2) versus normalized power output. The results showed that: There were significant (p<.05) differences in oxygen uptake (VO2) at 150W workload, AP> UP, at exhaustion, UP>DP>AP. There were no significant differences in rms EMG at 150W and 200W. There were significant (p<.05) differences in the time to exhaustion, UP>DP and UP>AP. For normalized slope data, there were no significant differences among three positions for the oxygen uptake (VO2) versus the power output. There was a significant difference in rms EMG versus the power output, DP >AP. Different body positions affected physiological responses during the incremental test on the cycle ergometer. Vastus lateralis recruitment was proportional to exercise intensity in DP. Moreover, the closer the body to the horizontal position, the more likely the human working functions to the limited and thus the more reduced exercise performance on the cycle ergometer.
