Fig. 2. Relationship between moment arm and oxygen consumption rate (Formula 8O2) in ml kg–1 min–1 at 16 km h–1. Dots are individual participants, the line is the best fit for the theoretical model y=ax–2+b, where x is moment arm in cm and y is Formula 8O2 in ml kg–1 min–1 at 16 km h–1 (a=–628.1, b=75.65, r=0.77). This model was derived from Eqn 7, assuming a linear spring (n=1). A very similar fit with r=0.76 can be obtained for the model y=cx–1.5+d, which is based on the assumption that n=2.
