  • Purpose. To investigate the validity of the Sense Wear Pro Armband (SWA) to measure energy expenditure (EE) in healthy participants using wheelchair ergometry as an exercise modality.

    Method. Minute by minute EE was measured simultaneously using the SWA and indirect calorimetry(IC) during three different wheeling speeds including self-selected speed (0.81 m/s), moderate speed (1.11 m/s), and fast speed (1.73 m/s).

    Results. Twenty healthy volunteers (age = 34.0 (5.8) years)participated. The intraclass correlation coefficients (ICCs) were 0.50 (p=0.010), 0.59 (p=0.003), and 0.68 (p=0.000) for the self-selected speed, moderate speed, and fast speed wheeling, respectively. The SWA overestimated EE 57.8%, 57.4 %, and 63.7% for self-selected speed, moderate speed, and fast speed, respectively.

    Conclusions. The SWA failed to provide an accurate estimate of EE as measured by indirect calorimetry for wheelchair ergometry exercise in healthy subjects. The SWA overestimated EE for all exercise intensities.
