In our experiment, the ability of proton-translocation across mitochondrial membrane and the activity of ribonucleotide reductase were determined in skeletal muscle mitochondria and myocardial mitochondria in trained rat (60 min/day, 7 days) after unloading swimming for 60 min.
本实验通过对有氧运动训练 (无负重游泳 6 0分钟 /天 ,7天 )大鼠游泳运动后的骨骼肌、心肌线粒体质子跨膜转运能力及核糖核苷二磷酸还原酶活性的测定 ,发现有氧运动训练的大鼠在定量运动负荷后 (6 0分钟无负重游泳 ) ,骨骼肌线粒体的质子跨膜转运能力显著提高 (P <0 0 5 ) ,以及线粒体的核糖核苷二磷酸还原酶活性明显高于对照组 (未经训练之大鼠 ,P <0 0 0 1)。
