研究有氧耐力练习对小鼠肌肉组织自由基损伤的影响。方法是测定游泳练习小鼠肌肉组织中的丙二醛(MDA)的生成量和谷胱甘肽过氧化氢酶(GSH PX)活力,同时用急性剧烈运动的小鼠肌肉组织中MDA的生成量和GSH PX的活力作对照。结果表明,经过游泳练习的小鼠比急性剧烈运动的小鼠肌肉组织中MDA显著降低(P<0.05),而两种状况下小鼠骨骼肌与平滑肌组织中GSH PX活性差异有显著性(P<0.05),从而得出结论,有氧耐力练习的小鼠比急性剧烈运动的小鼠肌肉组织中抗自由基损伤的能力增强。  相似文献

Shoe cleat position during cycling and its effect on subsequent running performance in triathletes     

Tomas Viker 《Journal of sports sciences》2013,31(9):1007-1014

Abstract

Research with cyclists suggests a decreased load on the lower limbs by placing the shoe cleat more posteriorly, which may benefit subsequent running in a triathlon. This study investigated the effect of shoe cleat position during cycling on subsequent running. Following bike-run training sessions with both aft and traditional cleat positions, 13 well-trained triathletes completed a 30?min simulated draft-legal triathlon cycling leg, followed by a maximal 5?km run on two occasions, once with aft-placed and once with traditionally placed cleats. Oxygen consumption, breath frequency, heart rate, cadence and power output were measured during cycling, while heart rate, contact time, 200?m lap time and total time were measured during running. Cardiovascular measures did not differ between aft and traditional cleat placement during the cycling protocol. The 5?km run time was similar for aft and traditional cleat placement, at 1084?±?80?s and 1072?±?64?s, respectively, as was contact time during km 1 and 5, and heart rate and running speed for km 5 for the two cleat positions. Running speed during km 1 was 2.1%?±?1.8 faster (P?<?0.05) for the traditional cleat placement. There are no beneficial effects of an aft cleat position on subsequent running in a short distance triathlon.  相似文献
