Abstract:
A randomized controlled trial about the effects of exercise on cognitive function in elderly was conducted by searching the five major electronic databases at home and abroad. According to the evidence level of Oxford Centre for Evidence-Based Medicine, the included literatures were classified, and the effects of physical exercise variables on cognitive function were analyzed.An expert consensus on the dose-effect relationship of physical exercise delaying cognitive decline was written.Aerobic exercise has a better effect on practical function. The recommended program is 3 times a week with moderate intensity, 30-60 minutes each time, and 12-24 weeks duration.Resistance exercise has a better effect on practical function, with the recommended program 2 times a week with moderate and high intensity, 60 minutes each time, and 24 weeks duration. Multi-component exercise has a better effect on the global cognitive function, memory function and executive function, with the recommended program 3-4 times a week with moderate intensity, 30-60 minutes each time, and 12-24 weeks duration.Traditional Chinese national sports have better effects on the global cognitive function and the recommended program is more than 3-5 times a week with moderate intensity, 30-60 minutes each time, and 12-24 weeks duration.
