Beginning of preparatory phase (spring competition round) (N = 14) |
P |
|---|---|---|---|
| VO2max (mL/kg/min) | 60.8 (58.4 - 64.4) | 62.2 (60.0 - 64.4) | 0.551 |
| HRmax (beats/min) | 203 (189 - 209) | 189 (187 - 203) | 0.433 |
| AT (beats/min) | 165 (155 - 177) | 161 (154 - 174) | 0.683 |
| RQ | 1.06 (1.06 - 1.09) | 1.07 (1.06 - 1.09) | 0.382 |
| RC | 175 (172 - 192) | 172 (172 - 192) | 0.660 |
| VE (L/min) | 146.7 (122.0 - 156.7) | 156.4 (133.6 - 167.7) | 0.363 |
| MVV (L/min) | 184 (172 - 192) | 190 (183 - 200) | 0.363 |
| MET (mL/kg/min) | 17.3 (16.7 - 18.4) | 17.8 (17.1 - 18.7) | 0.510 |
| Rf | 58.0 (56.1 - 67.5) | 58.8 (56.8 - 66.7) | 0.975 |
| The table presents median (interquartile range) values. VO2max - maximum oxygen uptake. HRmax - maximum heart rate. AT - anaerobic threshold. RQ - respiratory quotient (volume ratio of emitted CO2 to oxygen uptake). RC - respiratory compensation. VE - minute ventilation. MVV - maximal voluntary ventilation. MET - metabolic equivalent. Rf - respiratory frequency. The difference was tested using the Wilcoxon matched pairs test. P < 0.05 was considered statistically significant. | |||
