摘要
目的:探讨在海拔2260m高原低氧环境下对大鼠进行跑台递增负荷训练后,辅以不同增压氧恢复手段对大鼠力竭运动能力的影响。方法:6组(每组8只)雌性Wistar大鼠进行持续6天的跑台递增负荷训练,其中F组和G组在模拟海拔4500m高度下进行跑台训练,训练后即刻辅以不同模式的增压氧恢复手段,第7天进行力竭运动并记录运动时间。结果:施加不同增压氧辅助手段后C组、D组、E组和G组大鼠的力竭运动能力好于未进行增压氧辅助手段的B组和F组,与F组相比差异显著(P<0.05),并以0.2MPa/h加压方式对于提高大鼠抗缺氧和抗疲劳能力的效果明显。结论:采用不同增压辅助恢复手段可有效提高大鼠的抗疲劳能力,进而提高运动能力,并以0.2MPa/h增压辅助手段效果最为明显,但针对人体有明显抗疲劳、抗缺氧效果的增压强度和时间模式尚需进一步研究。
Objective： the paper discusses the effects of different auxiliary booster recovery on the rats＇ exhausted movement ability changes after increasing load training on treadmill under the hypoxia plateau （2260m）. Methods： Six groups（n=8）, the Waster rats have treadmill incremental training for 6 days, Group F and Group G are having treadmill training at the altitude of 4500re,all of them have the different auxiliary booster recovery methods after training. At the seventh day, let them have exhausted movement, at the same time make the records. Results： the capacity of C, D group, E group and G group rats are much better than group B and F group which has no auxiliary booster recovery, and had the significant difference （P〈0.05）. the effect of anti-anoxia and anti-fatigue of the group having recovery methods especially 0.2MPal for 1 hour per day are helpful to improve rats＇ anti-anoxia and anti-fatigue abilities, The results show that： different auxiliary booster recovery methods can improve the anti- fatigue ability, further to increase the exercise ability and the 0.2Mpa/h auxiliary booster recovery method is the most effective, however the effects for human beings need further researches.
