The effect of physical exercise duration on mental health, anxiety (), and depression () of the older adults () had a positive effect. Among them, the intervention effect on mental health (d = −2.51) and depression (d = −2.67) of the older adults when the single exercise duration less than 30 minutes is the largest, and the intervention effect on anxiety of the older adults was the largest when the exercise duration is 30–60 minutes (d = −1.21) (Table 7).
