Imagine completing considerably fewer squat repetitions and improving your jumping performance MORE.
That's exactly what happened in an eight-week experiment involving 22 young men.
One group stopped their squat sets when repetition speed dropped by 20%. The other continued until a 40% loss of speed.
The first group completed approximately 40% fewer repetitions.
Their countermovement jump improved by 9.5%, compared with 3.5% in the other group.
And here's another interesting detail: both groups improved their squat strength.
This brings us to an important coaching question.
If I'm programming squats for you because you want to jump higher, sprint faster or develop explosive power, how much fatigue should I allow you to accumulate during each set?
The faster repetitions and the slower repetitions impose different demands. We have to consider those differences when designing the training.
A later review found a small average advantage for lower velocity loss in jump and sprint outcomes, although the evidence doesn't give us one universally optimal stopping percentage.
The lesson I take into coaching is straightforward: decide what adaptation you're training for, then programme the load, repetitions, speed and fatigue accordingly.

Do your squat sets usually end because you've reached the prescribed repetitions, or because the quality of your repetitions is dropping?
