To study the effects of training at moderate altitude on muscle metabolism; we defined the lowest altitude which affected the aerobic capacity in man, and we studied the differences between training at an altitude of 2300 m and at sea level, both at the same relative (to the VO2max) and absolute intensity of work. We confirmed that at 1200 m the VO2max is decreased in sedentary and well-trained persons. Elite athletes already at 900 m decrease their VO2max. We have found an increase in myoglobin, oxidative enzyme activities and endurance capacity and a decrease in some glycolytic enzyme activities associated with simulated altitude training. We conclude that when the amount of training performed at altitude is similar to the amount at sea level, the stimulus of hypoxia associated with the training stimulus induces improvements in the muscle oxidative enzymes and myoglobin.
为研究中等海拔训练对肌肉代谢的影响；我们确定了影响人体有氧能力的最低海拔高度，并研究了在2300米海拔和海平面进行训练的差异，两者训练强度均为相同的相对（相对于最大摄氧量）和绝对强度。我们证实，在1200米海拔时，久坐不动者和训练有素者的最大摄氧量均会下降。优秀运动员在海拔900米时最大摄氧量就会下降。我们发现，与模拟海拔训练相关的肌红蛋白、氧化酶活性和耐力能力有所增加，一些糖酵解酶活性有所下降。我们得出结论，当在海拔进行的训练量与在海平面进行的训练量相似时，与训练刺激相关的缺氧刺激会促使肌肉氧化酶和肌红蛋白得到改善。
