What is the target contact time for reactive jumps?

For maximum RSI, elite athletes target 300 ms indicate the athlete is using the drop jump as a countermovement jump (slow SSC) rather than a reactive jump (fast SSC).

How does drop height affect contact time?

Increasing box height increases impact force, requiring longer GCT to control landing. If the athlete cannot maintain GCT targets, the box height is too high for their current reactive strength. Progress height only when GCT remains below target.
