| pre-CR | post-CR | |
|---|---|---|
| AT-WR (W) | 36.1 ± 18.0 | 40.0 ± 19.9 |
| AT (ml/min/kg) | 10.2 ± 2.5 | 11.2 ± 3.1* |
| peak WR (W) | 68.8 ± 22.6 | 76.3 ± 31.9 |
| peak VO2 (ml/min/kg) | 15.2 ± 4.8 | 17.1 ± 6.0* |
| VE vs. VCO2 slope | 35.9 ± 12.0 | 34.2 ± 11.8 |
| VO2/WR | 8.6 ± 2.4 | 8.6 ± 3.6 |
pre-CR: before phase II cardiac rehabilitation program; post-CR: after phase II cardiac rehabilitation program; AT: anaerobic threshold; WR: work rate; VO2: oxygen uptake; VE: minute ventilation; VCO2: carbon dioxide output. Pre-CR and post-CR data were compared using Wilcoxon signed-rank test. *p<0.05. Values are means ± SD, n=12
