Model | Expression of VO_{2}max | In terms of linear dimensions (L) | Comment to model |

1 | L·min^{−1} | L^{3}·L^{−1} thus L^{2} | Not scaled for body size |

2 | mL·min^{−1}·kg^{−1} | L^{3}·L^{−1}·L^{−3} thus L^{−1}. | The traditional scale ratio |

3 | mL·min^{−1}·kg^{−0.67} | L^{3}·L^{−1}·L^{−2} thus L^{0}. | Using the theoretical mass exponent of 2/3 based on dimensional analysis6 8 |

4 | Women: mL·min^{−1}·kg ^{−0.52} Men: mL·min^{−1}·kg ^{−0.76} | L^{3}·L^{−1}·L^{−2} thus L^{0}. | Using sex-specific exponents derived from large population samples9 |

5 | mL·min^{−1}·height^{−2} | L^{3}·L^{−1}·L^{−2} thus L^{0} | Using height as body size measure for scaling8 19 |

6 | mL·min^{−1}·(kg^{1}·height^{−1})^{−1} | L^{3}·L^{−1}·(L^{3}·L^{−1})^{−1} thus L^{0} | |

7 | mL·min^{−1}·WC^{−2} | L^{3}·L^{−1}·L^{−2} thus L^{0} | Using waist circumference and height as body size measure for scaling |

8 | mL·min^{−1}·(WC^{3}·height^{−1})^{−1} | L^{3}·L^{−1}·(L^{3}·L^{−1})^{−1} thus L^{0} |
