Brief Summary

The prevalence, low cost, and low burden of wearable devices that provide quantitative and qualitative feedback on a subject's activity level present an opportunity for the use of these devices in clinical and observational studies. However, the accuracy and reproducibility of any given device may vary with device design and algorithm implementation. Therefore, validation of emerging technologies against known standards such as analysis of exhaled breath and currently available medical devices is critical. This is a single center, two-cohort, single period, open-label, methodology study. No investigational product will be used in this study. Eligible subjects will wear 2 generations of SenseWear Armband devices, 2 ActiGraph GT9x devices (one on the wrist and one on the waist) and a Garmin Vivofit 2 activity tracker wristband for up to 24 hours per day. Subjects who consent to participate in an optional sub-study will wear a SOMNOwatch Plus EEG-6 device while sleeping. Subjects will perform a variety of laboratory and field-based exercise tests and strength exercises using Latex-Free Therabands.The co-primary objectives of this study are firstly to compare the outputs of the test devices (SenseWear Armband Gecko and Actigraph GT9x) to those of the SenseWear Armband MF and secondly to assess the sensitivity and accuracy of the test devices in subjects with COPD or asthma while performing laboratory-based exercise testing.

Outcome Measures

Primary Outcomes (3)

• Energy expenditure [kilocalories per minute]

  Energy expenditure will be assessed by test devices at various levels of exertion during field-based and laboratory-based exercise tests. Graphical and/or statistical comparisons will be made between test devices and with information derived from indirect calorimetry obtained by exhaled gas analysis, where available.

  Up to Day 2

• Energy expenditure [metabolic equivalents]

  Energy expenditure will be assessed by test devices at various levels of exertion during field-based and laboratory-based exercise tests. Graphical and/or statistical comparisons will be made between test devices and with information derived from indirect calorimetry obtained by exhaled gas analysis, where available.

  Up to Day 2

• Step counts [total number of steps taken]

  Step counts will be collected by test devices at various levels of exertion during field-based and laboratory-based exercise tests. Graphical and/or statistical comparisons will be made between devices and with manually counted steps, where available.

  Up to Day 2

Secondary Outcomes (5)

• Number of subjects with adverse events (AE) or serious adverse events (SAE).

• Number of subjects with abnormal vital signs related to interventions.

  Screening and Days 1 and 2

• Forced Expiratory Volume in 1 second (FEV1)

  Screening
