Correlation test of variables
In order to verify the relationship between variables, Person correlation analysis was conducted for the data after intervention. The results showed that grip strength and standing on one foot with eyes closed respectively were significantly positively correlated with SWB, indicating that the better the physical fitness, the higher the SWB. There was a significant positive correlation between the sense of self-control and SWB. And inhibitory and updating function respectively were positively correlated with self-control (see in Table
