Table 3. Means (±standard deviation) of the minimum distance of the lateral malleolus marker from obstacle for the leading and trailing limb and the distance of the heel marker from the obstacle during heel stance phase after and before the obstacle for the leading and trailing limb, respectively.
10% 20% p-value
Leading limb Minimum distance (cm) Before fatigue 17.0 (2.9) 15.8 (2.8) pf = .950
After fatigue 17.4 (3.7) 15.9 (4.7) ph = .004
5 minutes after fatigue 17.0 (4.8) 16.0 (5.1) pf×h = .927
Distance after obstacle (cm) Before fatigue 28.0 (6.7) 27.1 (7.1) pf = .216
After fatigue 31.0 (7.7) 28.2 (6.6) ph = .055
5 minutes after fatigue 28.9 (9.8) 26.4 (7.5) pf×h = .322
Trailing limb Minimum distance (cm) Before fatigue 10.7 (2.7) 8.3 (2.9) pf = .480
After fatigue 9.0 (5.7) 7.9 (3.6) ph = .027
5 minutes after fatigue 9.4 (3.1) 8.1 (3.9) pf×h = .644
Distance before obstacle (cm) Before fatigue 45. 8 (4.7) 44.7 (4.7) pf = .020
After fatigue 40.5 (8.3) 45.0 (4.5) ph = .146

pf, ph, and pf×h: significance level for the factors concerning fatigue (before, after and 5 minutes after), the obstacle height (10% and 20% of lower limb length), and their interaction, respectively.
