doi: 10.3390/jfmk9040275
Figure Lengend Snippet: The relationship between the Apple Watch Series 9 and Parvo Medics on measures of energy expenditure (EE) for rest (panel A ; r = 0.495; p < 0.001), 0 min (panel B ; r = 0.095; p = 0.430), 2 min (panel C ; r = 0.261; p = 0.220), 4 min (panel D ; r = 0.535; p = 0.017), 6 min (panel E ; r = 0.585; p = 0.002), 8 min (panel F ; r = 0.554; p = 0.048), 10 min (panel G ; r = 0.520; p = 0.003), and post-rest (panel H ; r = 0.641; p < 0.001) in the participants in the study (N = 30). Data presented as values. * Statistical significance p < 0.05.
Article Snippet: Participants completed a 10 min treadmill protocol with varying speeds and inclines while wearing an Apple Watch Series 9, a two-way non-rebreathing mouthpiece connected to a Parvo Medics metabolic cart, and a Polar H7 chest strap to measure EE and HR.
