BACKGROUND
This study aimed to investigate the validity and reliability of the energy expenditure (EE) estimation of Apple Watch® among college students.
METHODS
Thirty college students completed two sets of three 10-minute treadmill walking and running trials while wearing three Apple watches and being connected to indirect calorimetry. The walking trials were at speeds of 54, 80, and 107 m·min-1 while the running trials were at 134, 161, 188 m·min-1. Energy expenditure comparisons were made using Two-way ANOVA with repeated measures. Reliability was analyzed by Intraclass Correlation.
RESULTS
There was no significant device x speed interactions (F (15, 696)=1.113, P=0.341) between the indirect calorimetry (criterion) and Apple Watch®. The lowest Inter-Class Correlation (ICC) scores were 0.49 (95%CI) at 54 while the highest were 0.72 (95%CI) at 107 and 134 m·min-1.
CONCLUSIONS
Apple Watch® demonstrated a low to moderate validity and reliability on measuring EE.
背景
本研究旨在调查苹果手表在大学生中能量消耗（EE）估计的有效性和可靠性。
方法
30名大学生戴着三只苹果手表并连接间接测热法，完成两组三次10分钟的跑步机步行和跑步试验。步行试验速度分别为54、80和107米·分钟-1，跑步试验速度分别为134、161和188米·分钟-1。使用重复测量的双向方差分析进行能量消耗比较。通过组内相关分析可靠性。
结果
间接测热法（标准）与苹果手表之间没有显著的设备×速度交互作用（F(15, 696)=1.113，P=0.341）。组内相关系数（ICC）得分最低为54米·分钟-1时的0.49（95%CI），最高为107和134米·分钟-1时的0.72（95%CI）。
结论
苹果手表在测量能量消耗方面表现出低到中等的有效性和可靠性。
