This study compared the validity of a new Omron HJ-303 piezoelectric pedometer and 2 other pedometers (Sportline Traq and Yamax SW200).
To examine the effect of speed, 60 subjects walked on a treadmill at 2, 3, and 4 mph. Twenty subjects also ran at 6, 7, and 8 mph. To test lifestyle activities, 60 subjects performed front-back-side-side stepping, elliptical machine and stair climbing/descending. Twenty others performed ballroom dancing. Sixty participants completed 5 100-step trials while wearing 5 different sets of the devices tested device reliability. Actual steps were determined using a hand tally counter.
Significant differences existed among pedometers (P < .05). For walking, the Omron pedometers were the most valid. The Sportline overestimated and the Yamax underestimated steps (P < .05). Worn on the waist or in the backpack, the Omron device and Sportline were valid for running. The Omron was valid for 3 activities (elliptical machine, ascending and descending stairs). The Sportline overestimated all of these activities, and Yamax was only valid for descending stairs. The Omron andYamax were both valid and reliable in the 100-step trials.
The Omron HJ-303, worn on the waist, appeared to be the most valid of the 3 pedometers.
本研究比较了新的欧姆龙 HJ-303 压电计和另外两种计步器（Sportline Traq 和 Yamax SW200）的有效性。
为了检验速度的影响，60 名受试者在跑步机上以 2、3 和 4 英里/小时的速度行走。20 名受试者还以 6、7 和 8 英里/小时的速度跑步。为了测试生活方式活动，60 名受试者进行了前后左右踏步、椭圆机和上下楼梯。另外 20 名受试者进行了交际舞。60 名参与者穿着 5 套不同的测试设备完成了 5 次 1000 步的测试，以测试设备的可靠性。实际步数通过手动计数器确定。
计步器之间存在显著差异（P <.05）。对于步行，欧姆龙计步器最准确。Sportline 计步器高估了步数，而 Yamax 计步器低估了步数（P <.05）。戴在腰部或背包上，欧姆龙和 Sportline 设备对跑步是有效的。欧姆龙对 3 种活动（椭圆机、上下楼梯）是有效的。Sportline 高估了所有这些活动，而 Yamax 只对下楼梯有效。在 100 步试验中，欧姆龙和 Yamax 都是有效且可靠的。
戴在腰部的欧姆龙 HJ-303 似乎是这 3 种计步器中最准确的。
