大鼠负重爬梯抗阻训练实验装置的改进
Improvement of the resistance exercise apparatus of climbing ladder with load on rats
摘要
Abstract
Objective To improve the resistance exercise apparatus of climbing ladder with load on rats, and to observe the technological, athletic training and biological response to the improved experimental apparatus.Methods Thirty-six healthy SPF male Sprague-Dawley were randomly divided into control and exercise groups.The climbing ladder and weight bearing device were separately improved to develop a new resistance exercise apparatus of climbing ladder with load on rats.The exercise group took an 8-week incremental exercise program using this improved device.To observe the operation effect of this improved exercise apparatus.To observe the dynamic changes of average maximum load on SD rats from the exercise group during 8 weeks.To compare the effect of climbing ladder exercise with load on body weights of SD rats between the two groups.Results The improved climbing ladder was marked by the prioritization technique of architecture stabilization, weight bearing and easy cleaning.The improved bearing device has the advantages of being sturdy and durable, and simplemethod to calculating load.Moreover, the new experimental apparatus can be operated by one person during the exercise program.The average maximum load was successfully increased to 756 g after an 8-week exercise using the improved apparatus.Compared with the control group, the body weights of SD rats from the exercise group after training were significantly reduced (P<0.05).Conclusions The improved resistance exercise apparatus of climbing ladder with load can provide a more endurable and repeatable process in the study of rat strength training and it is recommended to use this new device in future experimental research.关键词
