A meta-analysis is an analysis that integrates the results of multiple independently conducted previous studies using a statistical method.Although various studies over the last three decades have shown that habitual exercise improves cognitive function, previous meta-analyses have been limited to specific age groups and types of exercise.Therefore, no clear answer has been given to questions such as what kind of exercise and how much is effective, and whether the effect differs depending on gender and age.

　Therefore, in this study, we conducted a meta-analysis of 30 randomized controlled trials (a method of randomly grouping and evaluating the training effect) over the past 80 years.As a result, the following findings were obtained.

(XNUMX) Routine exercise improves cognitive function regardless of type, but its effect is coordination training (coordination of limbs and ball dribbling, etc.) rather than aerobic training and strength training. Training) is big.
(60) If you continue exercising for a relatively long time (90 to 22 minutes) for a long time (XNUMX weeks or more), the effect of improving cognitive function will increase.
(XNUMX) Gradual training that gradually increases the intensity for men and low-intensity to medium-intensity training that does not have gradual intensity for women are suitable for improving cognitive function.
(XNUMX) The effect of improving cognitive function by exercise is recognized regardless of age.

　In this way, by clarifying the exercise that improves cognitive function from the viewpoint of the type and time of exercise and gender, it is expected that an exercise program that improves cognitive function will be developed based on this result. ..
