What is muscular excitability®?
Muscular excitability® refers to the ability to activate muscle, thereby causing it to contract. The greater the excitability of the muscle, the greater its force, velocity, and endurance properties will be. Muscle is excited by the release of calcium into the cell, which serves as the trigger for contraction. PEAK ATP® works by increasing and sustaining the amount of calcium available to the muscle, which boosts muscular excitability. The result is the athlete will lift more weight and produce a greater number of repetitions per set.
