Efficacy of a 6-week VR exergame for older adults with essential hypertension: A randomized controlled pilot trial

This randomized controlled pilot study compared the effects of virtual reality-based exergame training versus conventional group training on blood pressure, body composition, lung function, physical working capacity, and mobility in 35 older adults with essential hypertension. As part of the study, changes in FEV1, FVC, and FEV1/FVC ratio were measured using a Vitalograph Micro spirometer.
