克莱梅斯 (CLEMES)、S.A. 和 R.A. 帕克 (R.A. Parker)。增加我们对成人对计步器反应的了解。医学。科学。体育锻炼，卷。 41，第 3 期，第 674-680 页，2009 年。目的：调查佩戴密封和非密封计步器是否存在反应（如果有）。有或没有步数记录。方法：在第一次访问实验室时，为 63 名参与者（41 名女性和 22 名男性；年龄 = 23.6 +/- 9.6 岁。体重指数 = 22.7 +/- 3.0 kg.m(-2)）提供了一个密封的计步器（New Lifestyles NL-1000），并告知其是“身体姿势监测器”（秘密监测）。参与者在 1 周的清醒时间内佩戴计步器。返回实验室后，存储的步数被下载，参与者被告知该设备是计步器。参与者在另外三种条件下佩戴计步器——密封、未密封和未密封加上在所有活动日记中记录每日步数——每个条件持续时间为一周。每个条件（密封/未密封/日记）的参与顺序在参与者之间是平衡的。使用重复测量方差分析比较四种条件下记录的平均每日步数。结果：条件具有显着的总体影响（P < 0.001；隐蔽监测 = 每天 8362 +/- 2600 步；密封条件 = 每天 8832 +/- 2845 步；未密封条件 = 每天 9176 +/- 3299 步；日记条件 = 每天 9635 +/- 2709 步），后锄头分析显示平均步数明显更高日记条件下的结果高于秘密条件和密封条件下报告的结果（P < 0.003）。没有观察到显着的性别影响（P = 0.33）。结论：步数的最大增加出现在日记条件下的红色，这表明当要求参与者佩戴所有未密封的计步器并记录其步数时，对计步器的反应最大。这对于调查习惯性自由生活活动的短期计步器研究具有有效性意义，这些研究要求参与者提供每日步数日志。
CLEMES, S. A., and R. A. PARKER. Increasing Our Understanding of Reactivity to Pedometers in Adults. Med. Sci. Sports Exerc., Vol. 41, No. 3, pp. 674-680, 2009. Purpose: To investigate the presence of reactivity, if any, to wearing sealed and unsealed pedometers,. with and without step count recording. Methods: On the first visit to the laboratory, 63 participants (41 females and 22 males; age = 23.6 +/- 9.6 yr. body mass index = 22.7 +/- 3.0 kg.m(-2)), blinded to the study aim, were provided with a sealed pedometer (New Lifestyles NL-1000) and informed that it was a "body posture monitor" (covert monitoring). Participants wore the pedometer throughout waking hours for 1 wk. On return to the laboratory, stored step counts were downloaded, and participants were informed that the device was a pedometer. Participants wore the pedometer under three more conditions-sealed, unsealed, and unsealed plus logging daily steps in all activity diary-each having a duration of I wk. The order of participation in each condition (sealed/unsealed/diary) was balanced across participants. Mean daily step counts recorded during the four conditions were compared using a repeated-measures ANOVA. Results: There was a significant overall effect of condition (P < 0.001; covert monitoring = 8362 +/- 2600 steps per day; sealed condition = 8832 +/- 2845 steps per day; unsealed condition = 9176 +/- 3299 steps per day; diary condition = 9635 +/- 2709 steps per day), with post hoe analyses revealing that mean step counts were significantly higher in the diary condition than those reported during both the covert and sealed conditions (both P < 0.003). No significant gender effects were observed (P = 0.33). Conclusion: The greatest increase in Step Counts occur-red in the diary condition, suggesting that reactivity to pedometers is greatest when participants are requested to wear all unsealed pedometer and record their step counts. This has validity implications for short-term pedometer studies investigating habitual free-living activity that require participants to provide a daily log of their step counts.
