For muscular power training that involves multiple efforts, a rest period of 2 to 5 minutes is advised to allow for adequate recovery between sets. This time frame is crucial because the primary goal of power training is to maximize the output strength and speed during each effort.

Shorter rest periods, such as 30-60 seconds, would not provide sufficient recovery for the neuromuscular system, leading to fatigue that could negatively impact performance on subsequent efforts. Similarly, while rest periods of 5-10 minutes could potentially be beneficial, they typically extend beyond the necessary recovery time for most power training protocols, which can interrupt training efficiency. Resting for 10-15 minutes is excessive and generally unnecessary for muscular power training, as it may lead to a significant decrease in engagement and readiness to perform subsequent sets.

Thus, the 2-5 minutes of rest strikes an appropriate balance, facilitating sufficient recovery while maintaining training intensity and effectiveness.
