What does the speed of repetition control primarily affect?

The speed at which you perform repetitions mainly determines how quickly the muscle must contract during each rep. Tempo sets how long the muscle has to shorten (concentric) and lengthen (eccentric) under load, so faster movements directly test and train the muscle’s ability to contract swiftly and generate force in a given time. While slower tempos can increase time under tension and other factors can influence heart rate or flexibility, the core effect of repetition speed is on the muscle’s contractile performance—the ability to contract efficiently and forcefully under the set pace.
