后退跑与走对中老年人心肺机能及冠心病的影响

Influences of backward run and walk on cardio-pulmonary function and coronary heart disease of middle and old aged people

研究后退跑与走对人体心肺机能及冠心病的影响。结果显示:后退跑比相应向前跑速度均为150m·min-1的NE、VO2、HR、血HL含量分别高112%、84 6%、47 3%、212 5%,并有显著差异。而在每分钟增加2%的坡度运动至力竭时,向前跑(150m·min-1)比后退跑(110m·min-1)的VE、VO2、HR、血HL要高,这就要求在机体恢复期内,可用后退跑和走的练习来促进组织的修复,提高心肺机能,减少冠心病的发病率,对延缓衰老具有一定作用。

The study of influences of backward run and walk on the cardio-pulmonary function and coronary heart disease of the middle and old aged people showed that the amount of NE,VO2,HR and blood HL of the backward run was higher by 112%,84.6%,47.3% and 212.5% than the normal run with the speed of 150?m/minute. While 2% slope exercise were increased until (exhaust) for the normal run got higher VE,VO2,HR and blood HL than those of the backward run. This indicated that during the period of recovery,backward run and walk could be used to promote the recovery of the tissue and the cardio-pulmonary function. It was helpful to reduce the occurrence of coronary heart disease and retard aging.
