Current physical activity guidelines recommend physical activity of at least moderate intensity to gain health benefits. Previous studies have recommended a moderate-intensity walking cadence of 100 steps per minute for adults, but the influence of height or stride length has not been investigated.
the purpose of the current study was to determine the role of height and stride length in moderate-intensity walking cadence in adults.
seventy-five adults completed three treadmill walking trials and three overground walking trials at slow, medium, and fast walking speeds while V˙O2 was measured using indirect calorimetry. Five stride length-related variables were also measured.
mixed model regression analysis demonstrated that height explained as much variability in walking intensity at a given cadence as did two different measures of leg length and two different stride length tests.
the previous general recommendations of 100 steps per minute were supported for use where a simple public health message is needed. Depending on height, moderate-intensity walking cadence can vary by more than 20 steps per minute, from 90 to 113 steps per minute for adults 198 to 152 cm tall, respectively. Height should therefore be taken into consideration for more precise evaluation or prescription of walking cadence in adults to provide health benefits.
目前的身体活动指南建议至少进行中等强度的身体活动以获得健康益处。先前的研究建议成年人的中等强度步行步频为 100 步/分钟，但身高或步长的影响尚未得到研究。
本研究的目的是确定身高和步长在成年人中等强度步行步频中的作用。
75 名成年人在慢、中、快步行速度下完成了三次跑步机行走试验和三次地面行走试验，同时使用间接测热法测量 V˙O2。还测量了五个与步长相关的变量。
混合模型回归分析表明，身高对给定步频的行走强度的可变性解释与两种不同的腿长测量值和两种不同的步长测试一样多。
之前的一般建议 100 步/分钟得到了支持，适用于需要简单公共卫生信息的情况。根据身高的不同，成年人的中等强度步行步频可以相差超过 20 步/分钟，分别为 198 至 152 厘米高的成年人的 90 至 113 步/分钟。因此，身高应在评估或规定成年人的步行步频以提供健康益处时加以考虑。
