摘要： 目的探讨不同上下台阶方式对能量消耗的影响。方法用气体分析装置K4测定10名健康者(平均年龄32.2岁)在4种上下台阶方式(即双脚一阶前方、双脚一阶侧方、双脚一阶斜方、单脚一阶前方)下的氧耗量、二氧化碳消耗量、换气量、呼吸频率和心率,计算消耗的能量。上下台阶的频率为1秒1阶。结果氧耗量为双脚一阶斜方上和双脚一阶前方下最低,单脚一阶前方上下最高;心率为双脚一阶前方上下最低,单脚一阶前方上下最高;换气量为双脚一阶前方上下最低,单脚一阶前方上下最高;呼吸频率为双脚一阶斜方上和双脚一阶前方下最低,单脚一阶前方上下最高。结论不同上下台阶方式消耗的能量不同;双脚一阶前方和斜方上下适用于老年人和残疾人。

Abstract: ObjectiveTo study energy consumption in different patterns of ascending and descending the stairs.Methods10 healthy individuals (with an average age of 32.2) were examined with four patterns of ascending and descending the stairs. They were common pattern (one step on one stair step, and the next step on the next stair step), side-pattern (side-stepping), oblique pattern (subject will ascend/descend at 45° angle), and two-step-one stair pattern (subjects will walk one step at a time in single stair step before proceeding to the next stair step). Meantime, SaO2, heart rate, respiration rate, and ventilation rate were measured.ResultsDuring investigation it was found out that SaO2 and heart rate with normal pattern was the highest. No difference was noticed in SaO2 between side-pattern, oblique pattern,and two-step-one stair pattern. Heart rate with two-step-one stair pattern was found to be the lowest.Conclusion Two-step-one stair pattern and oblique pattern were suitable for aged and handicapped persons.
