In many sports, practitioners must reach their maximal jump height (h_max) under time constraints. This requires a reduction of the countermovement depth and so of the push-off distance (h_PO). The purpose of this study was to investigate how h_PO influences force–velocity (F–v) profiles (${\overline{F}}_0$, ${\overline{v}}_0$, ${\overline{\mathrm{P}}}_{\max }$, and S_Fv) and performance. Eleven participants (age: 26 [5] y, height: 175.6 [11.2] cm, mass: 76 [15] kg; squat 1RM: 129 [34] kg) performed maximal countermovement jumps. Kinetic and kinematic measurements were used to assess individual F–v profiles for 3 different h_PO conditions (h_PO-SMALL, h_PO-MEDIUM, h_PO-LARGE) from countermovement jumps performed under different load conditions (bodyweight [BW], BW + 8 kg, BW + 17 kg, BW + 40%1RM, BW + 70%1RM). Results indicated that ${\overline{F}}_0$ and ${\overline{\mathrm{P}}}_{\max }$ changed across h_PO conditions, while ${\overline{v}}_0$ remained constant. A lower h_PO led to a significantly higher ${\overline{F}}_0$ and ${\overline{\mathrm{P}}}_{\max }$. These changes resulted in a steeper S_Fv leading to a more force-oriented profile, a lower optimal S_Fv and a greater F–v imbalance. Reducing h_PO and modifying F–v profile led, to some extent, to a reduction in h_max. Performance is a compromise between h_PO, ${\overline{\mathrm{P}}}_{\max }$, and F–v imbalance, all influenced by countermovement depth. This explains why reducing countermovement depth to meet time constraint may lower performance.
