目的：本研究的目的是比较多个品牌的计步器在24小时内的步值。本研究评估了以下13种电子计步器：Accusplit联盟15 10（AC），自由式步行者专业版（FR），移动中的科罗拉多（CO），肯兹Lifecorder（KZ），新生活方式NL-2000（NL），欧姆龙HJ-105（OM），俄勒冈州科学PE 316 CA（OR），运动线330（SL 330）和345（SL 345），Walk4Life LS 2525（WL）、Yamax Digi-Walker EM-180（SK）、Yamax Digi-Walker SW-200（YX 200）和Yamax Digi-Walker SW-701（YX 701）。方法：10名男性（39.5 +/- 16.6岁，平均值+/-，SD）和10名女性（43.3 +/- 16.6岁），BMI范围为19.8至35.4 kg（.）m（-2）佩戴两个计步器24 h。标准计步器（YX 200）佩戴在身体左侧，对比计步器佩戴在右侧。在一天结束时，记录13个计步器中每一个的每种设备计数的步数。结果：受试者平均走了9244步。d（-1）。KZ、YX 200、NL、YX 701和SL 330产生的平均值与标准无显著差异。与标准相比，FR、AC、SK、CO和SL 345显著低估了步数（P < 0.05），WL、OM和OR显著高估了步数（P < 0.05）。此外，一些计步器低估了25%，而另一些则高估了45%。结论：KZ、YX 200、NL和YX 701似乎适合于大多数研究目的。鉴于计步器在体力活动研究中的潜力，有必要在测量“每天步数”时保持研究的一致性。"
Purpose: The purpose of this study was to compare the step values of multiple brands of pedometers over a 24-h period. The following 13 electronic pedometers were assessed in the study: Accusplit Alliance 15 10 (AC), Freestyle Pacer Pro (FR), Colorado on the Move (CO), Kenz Lifecorder (KZ), New-Lifestyles NL-2000 (NL), Omron HJ-105 (OM), Oregon Scientific PE316CA (OR), Sportline 330 (SL330) and 345 (SL345), Walk4Life LS 2525 (WL), Yamax Skeletone EM-180 (SK), Yamax Digi-Walker SW-200 (YX200), and the Yamax Digi-Walker SW-701 (YX701). Methods: Ten males (39.5 +/- 16.6 yr, mean +/-, SD) and 10 females (43.3 +/- 16.6 yr) ranging in BMI from 19.8 to 35.4 kg(.)m(-2) wore two pedometers for a 24-h period. The criterion pedometer (YX200) was worn on the left side of the body, and a comparison pedometer was worn on the right. Steps counted by each device were recorded at the end of the day for each of the thirteen pedometers. Results: Subjects took an average of 9244 steps(.)d(-1). The KZ, YX200, NL, YX701, and SL330 yielded mean values that were not significantly different from the criterion. The FR, AC, SK, CO, and SL345 significantly underestimated steps (P < 0.05) and the WL, OM, and OR significantly overestimated steps (P < 0.05) when compared with the criterion. In addition, some pedometers underestimated by 25% whereas others overestimated by 45%. Conclusion: The KZ, YX200, NL, and YX701 appear to be suitable for most research purposes. Given the potential for pedometers in physical activity research, it is necessary that there be consistency across studies in the measurement of "steps per day."
