Research published in the British Journal of Sports Medicine suggests that regular exercise can improve cognitive function in older adults. The study found that higher cardiorespiratory fitness levels were associated with better performance across multiple cognitive domains, including processing speed and executive function.
The researchers assessed 648 individuals between the ages of 65 and 80 and used a treadmill running test to measure peak oxygen consumption. They then evaluated cognitive ability using standardized neuropsychological tests. The results showed that higher cardiorespiratory fitness levels were positively correlated with better performance across all cognitive domains, even when controlling for age, gender, education years, and weight.
The benefits of exercise on cognitive function were particularly notable in women, those with less education, and those taking beta-blockers. Increasing moderate-to-vigorous levels of aerobic activities, such as brisk walking or jogging, can help improve cardiorespiratory fitness and support overall health.
Experts recommend that older adults aim to engage in at least 150 minutes of moderate aerobic activity per week, along with two strength training exercises per week. Group classes, outdoor activities, and setting achievable goals through fitness trackers can also provide motivation and make exercise more enjoyable.
While the study is observational and cannot definitively establish a cause-and-effect relationship, it highlights the importance of individualized exercise programs that consider cardiorespiratory fitness in optimizing cognitive health as we age.
