摘要：

背景：关于不同运动强度对机体的影响早有研究，并且取得了不少有价值的成果。但是对于不同运动强度对线粒体Na+,K+-ATP酶、Ca2+-ATP酶活性以及线粒体肿胀程度影响的研究较少。
目的：观察不同运动强度对大鼠骨骼肌线粒体Na+，K+-ATP酶和Ca2+-ATP酶以及线粒体肿胀的影响。
方法：将24只SD大鼠随机分为正常对照组，中等强度运动组和高强度运动组。正常对照组大鼠正常笼内生活，不运动。另2组游泳训练方式，分别建立中强度和高强度运动模型，进行相应的运动锻炼，训练4周。
结果与结论：中强度运动组线粒体Na+,K+-ATP酶、Ca2+-ATP酶活性与正常对照组相比均增高(P < 0.05)，线粒体肿胀程度降低(P < 0.05)；而高强度运动组线粒体Na+,K+-ATP酶、Ca2+-ATP酶活性与正常对照组相比均降低(P < 0.05)，线粒体肿胀程度增大(P < 0.05)。实验结果表明中强度运动可以保护线粒体Na+,K+-ATP酶、Ca2+-ATP酶的活性，提高线粒体功能；而高强度运动则降低了线粒体的功能。

Abstract:

BACKGROUND: There are many studies on the effects of different exercise intensities on the body, but studies about the effects of different exercise intensities on the activity of mitochondrial Na+, K+-adenosine triphosphatase (ATPase), Ca2+-ATPase and mitochondrial swelling are few.
OBJECTIVE: To investigate the effects of different exercise intensities on the activity of mitochondrial Na+, K+-ATPase and Ca2+-ATPase, as well as mitochondrial swelling.
METHODS: Twenty-four Sprague Dawley rats were randomly separated into three groups, namely, control, mid-intensity, high-intensity exercise groups. The control rats did not undergo swimming training, while the other two groups were given 4-week swimming exercises of different intensities.
RESULTS AND CONCLUSION: Compared with the control group, the Na+, K+-ATPase and Ca2+-ATPase activities increased (P < 0.05) and the extent of mitochondrial swelling decreased (P < 0.05) in the mid-intensity exercise group, but opposite in the high-intensity exercise group. These findings indicate that mid-intensity exercise can protect the activity of mitochondrial Na+, K+-ATPase and Ca2+-ATPase and increase the function of mitochondria, but high-intensity exercise can decrease the function of mitochondria.
