Table 1 Mechanical efficiency indices utilized in the present study and their interpretations

From: A Comparison of Methodological Approaches to Measuring Cycling Mechanical Efficiency

Indicator Interpretation Definition
GE Mechanical efficiency of a whole body \( \frac{W_{\mathrm{ext}}}{E_{\mathrm{tot}}} \)
T Rough indicator for GE \( \frac{{\mathrm{VO}}_2}{P_{\mathrm{out}}} \)
NE Mechanical efficiency for everything that can have adaptations \( \frac{W_{\mathrm{ext}}}{E_{\mathrm{tot}}-{E}_{\mathrm{rest}}} \)
WE Mechanical efficiency of an isolated musculoskeletal system \( \frac{W_{\mathrm{ext}}}{E_{\mathrm{tot}}-{E}_0} \)
DE Averaged mechanical efficiency of an isolated musculoskeletal system \( \frac{{\Delta W}_{\mathrm{ext}}}{{\Delta E}_{\mathrm{tot}}} \)
