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 | \( \frac{{\Delta W}_{\mathrm{ext}}}{{\Delta E}_{\mathrm{tot}}} \) |
