摘要
目的探讨大鼠负重爬梯抗阻实验装置的改进,观察改进装置的方法学、训练学和生物学效果。方法36只SPF级雄性SD大鼠随机分为安静对照组和训练组。对爬梯装置和负重装置进行分别改进后建立新的大鼠负重爬梯抗阻训练实验装置,实验组大鼠用改进装置进行8周负重递增训练。观察改进后的训练装置操作效果;动态观察实验组大鼠8周训练的平均最大负重变化;比较负重爬梯训练对两组大鼠体重的影响。结果改进后爬梯装置具有稳定性高、承重性好、易清洁的特性,负重装置具有结实耐用、计算简易的特点,实验员可单人操作完成训练全过程;用改进装置训练大鼠8周后的平均最大负重可达756 g;用改进装置训练大鼠体重比安静对照组显著降低(P<0.05)。结论改进的大鼠负重爬梯抗阻训练实验装置可为大鼠力量训练研究提供长期、反复的实验条件,建议推广使用。
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.
