A hitter jumps two hundred times in a match and never once from a standstill. The approach loads the plant, the plant loads the floor, and the floor decides how much of that momentum gets turned back upward.
Hardwood is fast, then it is not
A sprung court is quick early. As the match goes on, the losses move into your shoe: compressed foam, a flattened insole, a platform that quietly stopped returning force somewhere in the second set.
- Count your jumps for one full match — most hitters guess low by half.
- Film your approach in set one and set four. Compare the last two steps, not the swing.
- Test block jumps off both legs after conditioning, not before it.
Repeat jump is a different quality
Max vertical is a single-attempt number. Volleyball rewards the athlete whose twelfth jump of a rally looks like the second. Train short-contact bounding and low-box rebounds, and give the foot a stable, thin platform for the hundreds of contacts you never write down.
