Table 3.
Follow-up one-way repeated measures ANOVAs of center of mass (CoM) trajectory and velocity (section CoM trajectories and velocities) with preparatory posture [three levels: preferred preparatory posture before the imposed postures' trials (PT1), preferred preparatory posture after the imposed postures' trials (PT2), and stance width equal to 75% leg length (SW75) as a factor.
| Variables | PT1 | PT2 | SW75 | P-value (partial eta2) | |
|---|---|---|---|---|---|
| High dives | Horizontal distance traveled by CoM between CPF and IPF | 59.55 cm | 63.50 cm | 68.72 cm | 0.001 (0.58) |
| Vertical distance traveled by CoM between CPF and IPF | 10.25 cm | 9.88 cm | 15.19 cm | 0.009 (0.49) | |
| Countermovement range | 14.11 cm | 11.61 cm | 8.22 cm | 0.001 (0.58) | |
| Average horizontal CoM velocity at contralateral push-off | 1.07 m·s−1 | 1.17 m·s−1 | 1.43 m·s−1 | 0.003 (0.52) | |
| Average vertical CoM velocity at contralateral push-off | −0.27 m·s−1 | −0.25 m·s−1 | 0.01 m·s−1 | 0.006 (0.52) | |
| Low dives | Horizontal distance traveled by CoM from dive onset to CPF | 20.95 cm | 23.94 cm | 32.84 cm | 0.004 (0.51) |
| Vertical distance traveled by CoM from dive onset to IPF | 18.04 cm | 15.94 cm | 12.39 cm | 0.008 (0.45) | |
| Average horizontal CoM velocity at contralateral push-off | 0.59 m·s−1 | 0.68 m·s−1 | 0.96 m·s−1 | 0.005 (0.49) | |
| Vertical CoM velocity range | 0.92 m·s−1 | 0.88 m·s−1 | 0.72 m·s−1 | 0.02 (0.385) |
Only the tests with a significant result are reported in this table. CPF, contralateral peak force; IPF, ipsilateral peak force.
