The aims of this study were to describe the amount of non-ambulatory physical activity (PA) undertaken by a sample of Australian workers, and to evaluate different methods of accounting for non-ambulatory activities when using pedometers to measure physical activity.
Adults age 18 to 64 y (N = 204) wore a pedometer and recorded steps and non-step activity in a logbook for 7 d. Non-ambulatory activity was recorded by 28% of the participants (N = 52) with cycling and swimming the most frequently reported.
The mean time reported for non-ambulatory activities was 82.8 (standard deviation 80.0) min/wk. On average, participants recorded 8873 (standard deviation 2757) steps/d. Time in non-ambulatory activities was converted to steps equivalents using three different conversion methods. Use of the three methods added 333 to 721 steps/d in the whole sample, but 1153 to 2566 steps/d for those who reported non-ambulatory activity.
Suggestions are provided for accounting for non-ambulatory activities in interventions which rely on step count measures.
本研究旨在描述澳大利亚工人样本中进行的非步行身体活动（PA）量，并评估在使用计步器测量身体活动时计算非步行活动的不同方法。
18至64岁的成年人（N = 204）佩戴计步器，并在日志中记录步数和非步数活动，为期7天。28%的参与者（N = 52）记录了非步行活动，其中骑自行车和游泳是最常报告的活动。
报告的非步行活动平均时间为82.8（标准差80.0）分钟/周。参与者平均每天记录8873（标准差2757）步。使用三种不同的转换方法将非步行活动时间转换为等效步数。在整个样本中，使用这三种方法每天增加333至721步，但对于报告非步行活动的人来说，每天增加1153至2566步。
针对依赖步数测量的干预措施中计算非步行活动提供了建议。
