Harvard Medical School links brain health to this exercise …
(Erin Brodwin, Business Insider) A wealth of recent research suggests that any type of exercise that raises your heart rate and gets you moving and sweating for a sustained period has a significant, beneficial effect on the brain.
“Aerobic exercise is key for your head, just as it is for your heart,” says an article in a Harvard Medical School blog.
The results suggested that as little as one hour of exercise each week helped shield people against depressive episodes.
Notably, that exercise did not need to be aerobic — even participants who got moving without becoming breathless (perhaps with an activity like a long, moderately paced walk) were significantly less likely to report symptoms of depression compared with those who did no exercise.
A study in people with severe depression found that just 30 minutes of treadmill walking for 10 consecutive days was “sufficient to produce a clinically relevant and statistically significant reduction in depression.”
Remarkable overall results for age 50+
In older people, the best way to protect against age-related brain decline seems to be aerobic workouts.
A study found that in adults ages 60 to 88, walking for 30 minutes four days a week for 12 weeks appeared to strengthen connectivity in a region of the brain linked with memory.
The best overall health results — mental and physical — for people over 50 appear to come from a combination of aerobic workouts and resistance training (strengthening work like lifting weights or doing squats).
Joe Northey, an exercise scientist at the University of Canberra, said his research suggested that anyone in good health over age 50 should do 45 minutes to an hour of aerobic exercise “on as many days of the week as feasible.” SEE THE FULL STORY AT BUSINESS INSIDER.
