Changes in cardiorespiratory fitness for control group and intervention group.
| Pre-intervention | Post-intervention | Difference (Post-Pre) | p b | |
|---|---|---|---|---|
| Stages completed in 20mSRT | ||||
| CG | 6.4 ± 1.7 | 6.5 ± 1.7 | 0.1 ± 0.8 | 0.151 |
| IG | 6.6 ± 1.8 | 8.2 ± 1.9 | 1.6 ± 1.0 | <0.001 |
| Difference (IC-CG) | 0.2 ± 2.1 | 1.7 ± 2.3 | ||
| P a | 0.213 | <0.001 | ||
| Estimated VO2max (ml/kg/min) in 20mSRT | ||||
| CG | 39.7 ± 5.2 | 40.1 ± 5.2 | 0.4 ± 2.5 | 0.213 |
| IG | 40.3 ± 5.4 | 45.1 ± 5.6 | 4.8 ± 3.0 | <0.001 |
| Difference (IC-CG) | 0.6 ± 2.5 | 5.0 ± 7.3 | ||
| p a | 0.151 | <0.001 |
Values are means ± standard deviation (SD). CG = control group; IG = intervention group. p a -value (read in vertical) for comparison between groups by one-way analysis of covariance (ANCOVA) adjusted by age and sex. p b -value (read in horizontal) for comparison within groups by paired t-test. p significant level was set at p < 0.050.
