Table 2.
Fitness, BMI, and adherence for exercise groups.
| Mean (SD) | |||
|---|---|---|---|
| Variable | Baseline | 6 months | 12 months |
| FTB | |||
| VO2 max (ml/kg/min)a | 21.40 (4.13) | 21.28 (4.55) | 21.30 (4.39) |
| BMI | 28.35 (4.10) | 28.45 (4.39) | 28.49 (4.50) |
| Adherence | 83.38 (13.46) | 80.28 (13.50) | |
| WALKERS | |||
| VO2 max (ml/kg/min)a | 21.20 (4.13) | 21.53 (4.64) | 22.17 (5.05) |
| BMI (kg/m2) | 28.48 (4.42) | 28.10 (4.39) | 28.30 (4.66) |
| Adherence | 78.13 (14.31) | 76.00 (14.87) | |
aOnly VO2 max had a significant linear group × time interaction effect; p < 0.05, demonstrating that the intervention was effective in improving cardiorespiratory fitness; BMI, body mass index [BMI = (weight in kg)/(height in m2)]; adherence refers to percentage of exercise classes attended.
