The purpose of our study was to examine the monitoring capabilities of the Omron HJ-720ITC pedometer and determine the feasibility of using it in physical activity interventions.
Using data from an 8-week lifestyle-intervention study, we tested the capabilities of the pedometer for recording physical activity data. Data from a total of 28 subjects were used in our analysis. The total number of patient steps per day was recorded over the duration of an intervention, as well as "aerobic steps per day" (ie, those taken at a cadence of > 60 steps per minute for ≥ 10 consecutive minutes). Daily wear time was computed in order to ascertain participant compliance in wearing the pedometer. In addition, aerobic steps per minute were computed, providing an assessment of activity intensity during continuous walking bouts.
Total steps per day and aerobic steps per day increased from baseline assessment to Week 8. Participants exceeded 100 steps/minute for 89% of their aerobic minutes, suggesting that they were in the moderate-intensity range (3-6 metabolic equivalent tasks) when performing continuous bouts of walking (> 10 minutes).
The new pedometer is a reasonably priced, wearable activity monitor that is feasible for use in clinical and research settings.
我们研究的目的是检验 Omron HJ-720ITC 计步器的监测能力，并确定其在体力活动干预中的使用可行性。
我们使用来自 8 周生活方式干预研究的数据，测试了计步器记录体力活动数据的能力。我们的分析共使用了 28 位受试者的数据。在干预期间记录每天的总步数，以及“有氧运动步数”（即每分钟超过 60 步且连续 10 分钟以上的步数）。计算每日佩戴时间以确定参与者佩戴计步器的依从性。此外，计算了每分钟的有氧运动步数，以评估连续行走过程中的活动强度。
每天的总步数和有氧运动步数从基线评估增加到第 8 周。参与者的有氧运动分钟中有 89%超过 100 步/分钟，这表明他们在进行连续的行走（超过 10 分钟）时处于中等强度范围（3-6 代谢当量任务）。
新型计步器是一种价格合理、可穿戴的活动监测器，可在临床和研究环境中使用。
