Exercise boosts brain and body in frail seniors, study hopes

This study tests whether 3 months of aerobic and resistance training can improve physical reserve—the body's ability to handle stress—in 224 frail older adults living in the community. Researchers want to see if this exercise program helps preserve both physical mobility and cognitive function, even in people with signs of brain aging. Participants will do supervised exercises like jogging on the spot, agility drills, and weight training, and be compared to those receiving usual care.
