High-Intensity Exercise Boosts Memory in Seniors

A study from McMaster University found high-intensity treadmill workouts can significantly boost memory function in seniors, reports Forbes . The researchers included 64 seniors between 60 and 88 in the 12-week study. Participants engaged in moderate treadmill exercises that raised their heart rates up to 70 percent to 75 percent of their maximum for their age, or to 90 percent to 95 percent using shorter bursts of time, or performed gentle stretching exercises. Seniors in the high-intensity exercise group showed significant improvement on memory tests of up to 30 percent after the program, while those in the other groups exhibited no average improvement in memory. "The test looks at the ability to remember the details of new memories without mixing things up," said McMaster Professor Jennifer Heisz. She recommended that people exercise in ways that they love, "but if you are starting late and want to see results fast, our research suggests you may need to increase the intensity of your exercise." Heisz added that "exercise helps reduce the risk of dementia and mitigates some dementia symptoms, including improving activities of daily living and mobility and it may improve general cognition and balance."
