Table 2: Within-group differences in muscle and physical performance (Mean(SD)).
Mid: completion half training session (18 sessions); Post: completion all training session (36 sessions); WBV: whole body vibration group; CON: control group; CSA: cross-sectional area; VM; vastus medialis; TUG: Timed up-and-go test; 5STS: Five-repetition sit-to-stand test; 10MWT: 10-meter walking test. The p values were within-group comparisons versus baseline; * p<0.05 and ** p<0.01.
