After a hospital stay, high-intensity exercise improves fitness
Before leaving the hospital, 115 people with a chronic illness, ages 70-92 years, were randomly assigned to a high-intensity aerobic interval exercise program or low-intensity exercises and telephone support. After three months, both groups improved in scores on health-related quality of life and physical activity assessments. The high-intensity group significantly improved their scores on the Senior Fitness Test compared to those in the low-intensity group.
