What is the minimal rest time needed between vertical jump assessments so that the depleted ATP is fully replenished?

The replenishment of ATP (adenosine triphosphate) is critical for activities such as vertical jumps, which primarily rely on the phosphagen system for energy. During high-intensity efforts like these, ATP stores are rapidly depleted, and recovery time is required for full replenishment.

Research indicates that it takes about 3 to 5 minutes for ATP stores to fully recover after they have been significantly depleted during such high-intensity exertion. However, in practical terms, while some recovery can begin within the first 30 to 60 seconds, it’s generally accepted that a longer rest period is beneficial for allowing sufficient recovery of not just ATP but also phosphocreatine levels.

In this context, the answer indicating 90 seconds is appropriate as it strikes a balance, providing enough time for a significant portion of ATP to be restored, leading to potentially improved performance in subsequent assessments. It ensures that the athlete does not undertake subsequent jumps with residual fatigue from incomplete energy recovery, which can compromise results and risk injury.
