Abstract
Objective:To observe the effect of two different aerobic exercise modes (stair‐machine exercise and treadmill exercise) on cardiorespiratory fitness in healthy people .Methods:Thirty‐two healthy college students as subjects were divided into two groups randomly :walking group given walk exercise on treadmill (n=16) and stair‐climbing group given stair‐climbing exercise on stair‐machine (n=16) .The subjects from the walking group walked on the treadmill ,30 min per term ,5 terms per week ,and 5 days in all .The subjects from stair‐climbing group climbed stairs on the stair‐machine with the same frequency as that in the walking group .Results:There were sig‐nificant differences in MVV ,FEV1 ,FEV1/FVC ,PEF and 6MWD (P< 0 .05) ,but no significant difference in FVC in stair‐climbing group before and after exercise .There were significant differences (P< 0 .05) in FVC , FEV1 ,FEV1/FVC ,PEF and 6MWD ,but no significant difference in MVV in walking group before and after exer‐cise .There were significant differences (P<0 .05) in the range of increases of MVV ,FEV1/FVC ,PEF and 6MWD between two groups .Conclusion:Two aerobic exercise modes have significant effects on cardiorespiratory fitness , but stair‐climbing exercise has better effects on range of increases of MVV ,FEV1/FVC ,PEF and 6MWD than treadmill exercise in healthy people in short exercise term .关键词
