Traditional strength training is not the most effective way to maintain power; you need to incorporate specific power training that focuses on moving weight at higher speeds.

For power training, it is recommended to use lighter loads, around 20-30% of your one-rep max, to prioritize speed and reduce injury risk.

The 'use it or lose it' principle applies directly to motor units, as research shows exercise only preserves the motor units in the specific muscles being used.

As we age, we lose our fastest motor units first, which specifically impairs our ability to react and move quickly, even if basic strength seems fine.

Surprisingly, your ability to generate force quickly (power) declines more rapidly with age than your ability to move heavy weight (strength).

A recent study of nearly 4,000 people found that muscle power is a better predictor of mortality risk than muscle strength.

In power training, the movement should be fast and explosive during the concentric (lifting) phase, but slow and controlled during the eccentric (lowering) phase.
