Table 1.

R2 values for model fits at each velocity for all slopes.

Pmet vs. Ptrail
 Pmet vs. Plead
1.00m/s 1.25m/s 1.50m/s 1.00m/s 1.25m/s 1.50m/s
Linear 0.58* 0.59* 0.52* 0.56* 0.54* 0.58*
Quadratic 0.65* 0.65* 0.57* 0.76* 0.72* 0.71*

Linear and quadratic models describe the correlation between metabolic power (Pmet) and trailing (Ptrail) or leading (Plead) leg mechanical power. All models yielded significant correlations (P<0.05). We determined the best fit from the highest R2 values (indicated in bold).
