How exercise can keep your brain young and sharp

How exercise can keep your brain young and sharp

More evidence has been found proving that what is good for your heart is good for your head. New studies reveal that those of us who swim, run or do other decent exercises have brains that look, roughly 10 years younger than the brains of the lazier bunch out there.

"Our study showed that for older people, getting regular exercise may be protective, helping them keep their cognitive abilities longer," said Dr. Clinton Wright of the University of Miami, who led the study.

 “But it's not necessarily easy. Walking, golfing, bowling and yoga didn't count, and people need to start before they begin showing memory loss, Wright's team reported in the “reports Writes team”.

The case study of nearly 900 individuals indicated that 90% where categorised into the low-intensity group. These folks are part of a larger group taking part in a more superior study known as the Northern Manhattan Study.  They were questioned as to how long and how often had a workout during the past 14 days, or 2 weeks. 7 years later, they were tested for memory and thinking skills and got a brain MRI. Five years later, they reiterated these tests.

The 10 percent who said they took part in moderate - to high-intensity exercise scored better on the tests 12 years later. These included running, racquetball, aerobics, or calisthenics.

"We found that those with moderate-heavy activity had higher baseline scores and slower decline in comparison to inactive patients," the team wrote”. "The degree of decline was equivalent to the expected decline associated with approximately 10 years of cognitive aging." And if people already had signs of memory loss or mild cognitive impairment on their first exam, the exercise did not seem to help, the team found.

Many studies have shown that exercise may not prevent Alzheimer's but may delay it.

The results are in line with some research that found 2 years of physical training; healthier eating and brain exercise can greatly improve one’s memory.

Studies also show that even a little exercise, such as a quick walk to a nearby shop can help.
