Overrated sport!

The aging of society, the decline of cognitive ability in the elderly, and the increasing incidence of dementia have stimulated people's interest in delaying aging or preventing diseases.

Compared with short-term physical activity, long-term physical activity may be related to a greater improvement in cognitive performance.

Nevertheless, a longitudinal study published by UCLA researchers in "JAMA" shows that for middle-aged women, exercise has many health benefits, but it may not help maintain long-term cognitive function.

In this study, women’s cognitive abilities were tested in three key areas: cognitive processing speed (the speed at which the brain works), verbal memory (the ability to recall stories), and working memory (the ability to manipulate information).

The study found that in 21 years, women’s cognitive processing speed dropped by 8%, about 0.

Exercise level was positively correlated with the speech memory test score (EBMT-D), but not positively correlated with the decrease of EBMT-D score.

Exercise level has nothing to do with the annual decline rate of working memory score (DSB), and there are statistically significant differences in DSB scores of different races.

Outcomes and variables at follow-up

Researchers found that cognitive processing speed began to decline at the age of 51, and the decline accelerated after the age of 61.

However, Greendale pointed out that this study does not tell us whether increasing physical activity to a higher level helps maintain cognition.
