HR kinetics parameters during two repeated 1000 m bouts on the rowing ergometer, separated by 1.5 min (INT1.5), 3 min (INT3) and 6 min (INT6). Baseline: HR before the start of each bout; A1: amplitude and τ1: time constant of the primary component, respectively. Data are means (SE).
| Bout | Baseline (b·min-1) | A1 (b·min-1) | τ1 (s) | |
| INT1.5 | 1 | 106 (6) | 78 (6) | 12.6 (0.5) |
| 2 | 143 (7)* | 46 (6)* | 11.8 (1.2) | |
| INT3 | 1 | 105 (9) | 79 (7) | 12.9 (0.9) |
| 2 | 131 (5)* | 58 (4)* | 14.6 (1.6) | |
| INT6 | 1 | 105 (8) | 81 (7) | 13.3 (1.0) |
| 2 | 125 (3)* | 62 (4)* | 16.9 (1.5) |
* p < 0.05 compared with bout 1.
