Exercise could have a powerful effect on maintaining the health of patients with kidney disease, according to a study led by Dr. Cassianne Robinson-Cohen of the University of Washington Kidney Research Institute and the University of Washington School of Public Health. Dr. Robinson-Cohen and colleagues previously demonstrated a link between physical inactivity and the decline of kidney function in older adults. This study, published in the Journal of the American Society of Nephrology, was conducted to see if physical activity might help maintain the health of patients with chronic kidney disease – a condition affecting about 60 million people globally.
