Regular exercise will make your brain sharper

　　Published in the recent issue of nerve The research report in the journal Science stated that researchers from the University of Edinburgh in the United States conducted a study on 460 Scottish elderly people over the age of 79 who did not suffer from dementia.

Decades ago, when these seniors were just 11 years old, they took an intelligence test that included verbal reasoning and questions measuring numbers and space. The same intelligence test was repeated at age 79, and the seniors also took three fitness tests:

1. Walk nearly 20 feet within the time limit

2. Test the grip strength of your dominant hand (take the test three times and get the best result)

3. Lung function (amount of forceful expiration in one second)

Test results showed that the seniors with the highest fitness scores also had high intelligence test scores at age 11 and 79. This result remained true after adjusting for factors such as smoking, education, social status, and the ApoE gene that may later develop into Alzheimer's disease.

The researchers note that future studies should examine whether fitness can help with brain aging. At the same time, with the permission of your doctor, there is no reason not to exercise no matter your age.

disease The Centers for Disease Control and Prevention (CDC) recommends that all adults and adults engage in moderate exercise for 30 minutes a day at least five days a week; if you are just starting to exercise, you need to get approval from your doctor. The endurance, strength, balance and flexibility of aerobic exercise are very important for older adults. The fitness methods are as follows:

1. Aerobic exercise: walking, swimming, dancing, skating, walking, rolling a wheelchair, etc.

2. Intensity: Lift weights or cans, carry laundry or food, groceries, gardening, etc., and do stretches while sitting in a chair.

3. Flexibility: stretching, yoga or Tai Chi, etc.
