The term for increasing the number of motor units recruited during muscle contraction is known as recruitment. Recruitment refers to the process by which additional motor units are activated to produce more force when a muscle is required to generate greater tension. This is essential in strength training and physical activity where varying levels of force are demanded from the muscles.

As exercise intensity increases, the body progressively engages more motor units to meet the required force output. This ensures that the muscle can adapt to different loads and maintain efficiency during contraction. The ability to recruit more motor units contributes to overall strength and performance.

In contrast to recruitment, the force-velocity relationship describes how the velocity of muscle contraction changes with the load, which is not directly about the number of motor units. Summation involves a process where successive muscle twitches combine to create a larger force, but it focuses more on the timing of stimuli rather than the activation of additional motor units. Inhibition refers to the suppression of muscle activity, counteracting recruitment rather than promoting it. Understanding the concept of recruitment is fundamental in training as it underpins strength gains and adaptation in muscle performance.
