The Key Moments of a Countermovement Jump are:
| Key Moment | Description |
| Start of Movement | Point where a 20N threshold is exceeded. |
| Start of Braking Phase | Minimum force until end of eccentric phase. |
| Start of Deceleration Phase | Peak eccentric velocity until end of eccentric phase. |
| Start of Concentric Phase | Zero Velocity until take-off. |
| Start of Max. RFD | Point of steepest concentric force*. |
| End of Max. RFD | Peak take off force*. |
| Peak Take-off Force | Highest force value obtained during the jump (eccentric/concentric phase). |
| Take-off | Point where force is below 30N. |
| Landing | Point where force rises above 30N. |
| Peak Landing Force | Highest force obtained during landing phase. |
The key Phases of a Countermovement Jump are:
| Phase | Description |
| Weighing Phase | Steady phase for weight to be recorded. |
| Eccentric Phase | Phase containing negative velocity. |
| Braking Phase | Sub-phase within eccentric phase: minimum force until end of eccentric phase. |
| Deceleration Phase | Sub-phase within eccentric phase: peak eccentric velocity until end of eccentric phase. |
| Concentric Phase | Zero velocity until take-off. |
| Flight Phase | From take-off until landing. |
| Landing Phase | Point where force rises above 30N, then eventually returns to bodyweight. |
