The 2018 Physical Activity Guidelines for Americans (PAGA) recommend 150 minutes of moderate intensity activity for adult (18 years and older) Americans to promote health. PAGA also recommends that older adults (65+) engage in multicomponent and balance exercises weekly as a way to reduce falls and injuries from falls. This recommendation includes yoga, however, the current research and recommendations on using yoga to meet moderate intensity activity guidelines is limited. This study will utilize heart rate monitoring to determine if certain styles of yoga can be used to meet the PAGA.
The 2018 Physical Activity Guidelines for Americans recommend 150 minutes of moderate intensity physical activity each week to promote health. The most recent scientific advisory committee had insufficient evidence to provide recommendations on how the physical practice of yoga fits into the physical activity guidelines. Currently, there have been few studies done on yoga and its relative intensity. Previous randomized, cross-over trial to determine the effects of room temperature (hot yoga versus thermo-neutral environment) on subjective and objective markers of exercise intensity. They concluded that using objective markers (%VO2max) both thermo-neutral and hot yoga would be considered light intensity activity. Previous investigation of power yoga, heart rate, skin temperature, and body mass to determine that power yoga could be considered a moderate-vigorous intensity activity. Currently, there is a gap in the research on understanding the intensity of exercise offered within a typical yoga studio including "flow", hatha/classical, and hot yoga. Most yoga classes are about 60 minutes in length, and yoga classes of that length have not been investigated. There is also minimal research done on whether wearable activity trackers and accelerometers are able to accurately assess heart rate, and therefore activity intensity level in a yoga setting.
