But while water-based exercises are shown to have benefits for other aspects of health, until now there’s been limited evidence on whether it’s as beneficial on reducing cardiovascular disease risk for older adults and improving their heart health. Our latest study explored the long-term effects of regular, water-based aerobic exercise on cardiovascular health. We proved for the first time that they’re as effective as other types of aerobic exercise for lowering cardiovascular disease risk for older people. Our study enrolled …
