Table 3.
Difference in gait speed, balance performance, and self-rated health between high exercise (HE) and low exercise (LE) groups at baseline and at follow-up

High exercise group = physical activity 5 times/week or more for more than 30 min each time. Low exercise group (all others) = physical activity 1–4 times/week or less for 30 min or less each time
