Theoretical maximal vertical force (intercept) production extrapolated from the linear loaded countermovement jump F-v relationship |
Absolute F_{0} (N) Relative F_{0} (N.kg^{-1}) |
Maximal concentric force output in the vertical direction per unit of body mass. Describes the athlete’s force capability to project the centre of mass in the vertical direction. |

Theoretical maximal movement velocity (intercept) extrapolated from the linear loaded countermovement jump F-v relationship |
v_{0} (m.s^{-1}) |
Maximal movement velocity in the vertical direction during the countermovement jump. Describes the athlete’s ability to produce force at high velocities in the vertical direction. |

Maximal mechanical external power output in the vertical direction (P_{max} = F_{0} x v_{0}/4) |
Absolute P_{MAX} (W) Relative P_{MAX} (W.kg^{-1}) |
Maximal external power-output capability during the concentric action of the countermovement jump per unit of body mass. |

Slope of the force-velocity relationship |
Absolute S_{FV} (N.s.m^{-1}) Relative S_{FV} (N.s.m^{-1}.kg^{-1}) |
Index of an athlete’s individual balance between force and velocity capabilities. The more negative the value, and steeper the F-v slope, the more force-dominant the athlete is. |

Jump height |
JH (m) |
The maximal centre of mass displacement achieved during the flight phase of the countermovement jump. |

Flight time |
FT (sec) |
Ariel time of the athlete between ‘take-off’ until ‘landing’ in the countermovement jump. |

Take-off velocity |
TOV (m.s^{-1}) |
The maximal movement velocity at the conclusion of the propulsion phase |
