Table 1. Personal characteristics of the four practice groups: One–day monotonous (ODM), three-week monotonous (TWM), one-day seat-height (ODS) and one-day feedback (ODF).
| Study | Duration | Dose: | Test-nature | Age(yrs) | Height(m) | Weight(kg) | n-total | n-IFI | n-ISI |
| ODM | 1-day | 80 min | Monotonous | 22.0 (2.0) | 1.89 (0.11) | 81.1 (19.4) | 10 | 8 | 2 |
| TWM | 3-week | 80 min | Monotonous | 22.8 (3.9) | 1.89 (0.07) | 83.8 (11.6) | 13 | 8 | 5 |
| ODS | 1-day | 80 min | Variable(seat height) | 23.3 (2.6) | 1.86 (0.07) | 80.4 (14.0) | 10 | 6 | 4 |
| ODF | 1-day | 80 min | Variable(feedback) | 23.3 (4.1) | 1.84 (0.04) | 74.8 (6.1) | 6 | 4 | 2 |
| total | 22.9 (3.2) | 1.87 (0.07) | 80.0 (12.8) | 39 | 26 | 13 |
ISI are the ISI, i.e. the participants that increased less or equal to 10% in mechanical efficiency.
IFI are the IFI, i.e. the participants that increased more then 10% in mechanical efficiency.
