摘要
简介:像Apple Watch这样的腕带设备已经成为追踪身体活动的技术。本研究的目的是分析Apple Watch Series 7 (AW7)在跑步机上进行最大有氧能力测试时的最大心率(MHR)和最大能量消耗(MEE)。AW7测量值将与极地心率监测器(Polar)和PARVO代谢车(PARVO)进行比较。方法:22例健康活跃的受试者(平均±SD:年龄23.8±4.0岁;BMI(23.0±5.9 kg/m2)自愿参加研究。受试者确认了他们的活动、健康状况,并测量了身体成分和有氧能力。结果:PARVO组(109.6±41.7 kcal)与AW7组(98.7±24.3 kcal)的MEE差异无统计学意义;T (21)=1.5, p = 0.153。此外,PARVO组(186.2±16.2 BPM)与AW7组(189.3±8.5 BPM)的MHR差异无统计学意义;T (21)=-0.9, p = 0.379。结论:本研究的主要发现表明,与PARVO相比,AW7之间的MEE和MHR没有差异。
Measuring Energy Expenditure and Heart Rate during Maximum Aerobic Testing with the Apple Watch Series 7
Introduction: Wrist-worn devices such as the Apple Watch have emerged as technology for tracking physical activity. The aim of this research study is to analyze the Apple Watch Series 7 (AW7) with measurements of the maximum heart rate (MHR) and maximum energy expenditure (MEE) during a maximal aerobic capacity test on the treadmill. AW7 measurements will be compared to the Polar Heart Rate Monitor (Polar) and the PARVO Metabolic Cart (PARVO).
Methods: 22 healthy and active subjects (mean ± SD: age 23.8 ± 4.0 years; BMI 23.0 ± 5.9 kg/m2) volunteered for the study. The subjects confirmed their activity, health status, and were measured for body composition and aerobic capacity.
Results: No significant difference was found in MEE between PARVO (109.6 ± 41.7 kcal) and AW7 (98.7 ± 24.3 kcal) conditions; t(21)=1.5, p = 0.153. In addition, there was no significant difference in MHR between PARVO (186.2 ± 16.2 BPM) and AW7 (189.3 ± 8.5 BPM) conditions; t(21)=-0.9, p = 0.379.
Conclusions: The main findings of this study show that the MEE as well as the MHR between the AW7 compared to the PARVO are not different.
