When training for strength and power, athlete should aim to apply as much intent as possible to their movements. By trying to lift weights as explosively as possible, an athlete will accelerate and increase the recruitment of their largest, most powerful type II motor units through the Henneman Size Principle. This higher effort and intent in training in turn increases rate of force development, preferential type II fibre hypertrophy through the SAID principle.Until recently, tracking this intent relied on a keen coaches eye and subjective feedback methods. The ability to track and monitor objective metrics such as velocity and power has become a key coaching tool for providing motivation to athletes, improving training adaptations and reinforcing this higher intent to training.
