This mouse study suggests long-term aerobic exercise may support healthier heart aging.
Long-term cardio and the senolytic combo dasatinib plus quercetin each cut the number of worn-out zombie cells in aging mouse hearts. Mice got nine months of treatment starting in middle age, and both approaches helped their hearts relax and pump better. For anyone who does regular cardio, this hints that exercise may rival a drug here, though combining both gave no reported extra boost. This was only in mice, and whole-heart aging and inflammation markers did not change with any treatment.
