| 摘 要： | 利用Sensormedics2900型呼吸代谢仪,通过观察女子400米短跑优秀运动员完成递增负荷过程中呼吸代谢机能的变化,结果发现：呼吸代谢机能具有阶段性变化特征,呼吸商在递增负荷运动初期呈“V”型变化,假稳定状态阶段VE及RR指标均呈闽值性变化,其变化特征与神经及体液调节密切相关。

| Abstract: | This experiment for respiratory metabolic function varations by Sensormedics 2900 respiratory metabolic instrument. Excellent short - distance runners was selected as subjects to complete increment exercises. The results show: respiratory metabolic function has phase characteristic, respiratory quotient (RQ) variation appears "V' shape, and the indexes of VE and RR both varies in threshold at false stabe state. These change charateristics are closely related to nervous regulations and hormonal regulation. |
