Training Adaptation and Growth

Training adaptation is the process by which the body, given adequate recovery, rebuilds to a slightly higher capacity after the stress of each session, so the same demand feels easier next time.

Adaptation is specific to what is trained, is lost when training stops and varies from person to person. For sport and exercise medicine (SEM) these principles explain how training is programmed and progressed, why managing load matters for both performance and injury, and how training interacts with growth and maturation in young athletes.
