The physiological demands of Singing for Lung Health compared to treadmill walking

Abstract

Participating in singing is considered to have a range of social and psychological benefits. However, the physiological demands of singing, whether it can be considered exercise, and its intensity as a physical activity are not well understood. We therefore compared cardiorespiratory parameters while completing components of Singing for Lung Health (SLH) sessions, with treadmill walking at differing speeds (2, 4, and 6km/hr). Eight healthy adults were included, none of whom reported regular participation in formal singing activities. Singing induced physiological responses that were consistent with moderate intensity activity (METS: median 4.12, IQR 2.72 - 4.78), with oxygen consumption, heart rate, and volume per breath above those seen walking at 4km/hr. Minute ventilation was higher during singing (median 22.42L/min, IQR 16.83 - 30.54) than at rest (11L/min, 9 - 13), lower than 6km/hr walking (30.35L/min, 26.94 - 41.11), but not statistically different from 2km/hr (18.77L/min, 16.89 - 21.35) or 4km/hr (23.27L/min, 20.09 - 26.37) walking. Our findings suggest the metabolic demands of singing may contribute to the health and wellbeing benefits attributed to participation. However, if physical training benefits result remains uncertain. Further research including different singing styles, singers, and physical performance impacts when used as a training modality is encouraged.
