| 11 | 4↓ | – | 0.52↓ |
| 14 | 4↓ | – | 0.52↓ |
| 16 | 8↓ | – | 0.54↑ |
| 18 | 7↓ | – | 0.60↑ |
| 22 | 12 | – | 0.55↑ |
| 23 | 7↓ | – | 0.52 |
| 24 | 20↑ | – | 0.53 |
| 25 | 16 | – | 0.51↓ |
| 26 | 28↑ | 2↑ | 0.54 |
| Mean ± SD | 14.1 ± 11.1 | 0.3 ± 0.8 | 0.53 ± 0.03 |
| Team mean ± SD | 6.3 ± 6.0 | 0.0 ± 0.3 | 0.51 ± 0.03 |
HI accel, high-intensity accelerations; n, number; RHAA, repeated high acceleration ability; Ave accel, average acceleration; ↓, output lower than smallest worthwhile change; ↑, output greater than smallest worthwhile change; SD, standard deviation.
