摘要
目的 探讨最大运动负荷后的运动后过量氧耗与血乳酸、血糖及氨基酸代谢的变化关系 .方法 10名男子健康大学生 .通过活动跑台Bruce的方法进行渐增负荷跑 ,至力竭为止 .并测定气体代谢和血液中血乳酸、血糖及丙氨酸各指标 .结果 运动结束 30分钟恢复后 ,VO2 恢复到安静时水平 ,但血La浓度仍然比安静时水平高 ,丙氨酸在运动中上升 ,运动结束 30分钟恢复后减少 ,但并未恢复到安静时的水平 .结论 运动后过量氧耗与用于La的代谢之比 。
Objective The purpose of this study was to investigate the relationship between oxygen consumption (VO 2) on the recovery from incremental maximal exercise and the levels of the blood lactate (HLa), glucose and alanine metabolism.Methods The VO 2,HLa and plasma alanine were obtained using a modified version of Bruce's protocol until 30 min after exhaustion for 10 men.Results The VO 2 on recovery had returned to the pre-exercise, but the HLa concentrations and plasma alanine were significantly increased from rest to maximal exercise, and were significantly decreased thereafter, but remained above resting values for 30 min after maximal stage.Conclusions We conclude that oxygen consumption after exhaustive maximal exercise is related to glucose resynthesis through alanine metabolism, as compared with that from lactate metabolism.
