Supercompensation

First put forth by Russian scientist Nikolai N. Yakovlev in 1949–1959,[2] this theory is a basic principle of athletic training.

If the next workout takes place during the supercompensation period, the body will advance to a higher level of fitness.

If the next workout takes place after the supercompensation period, the body will remain at its base level.

Although this process is postulated as a model for recovery, some of its parameters are not fully understood from a fundamental perspective.

In classical sport science, the yearly (sometimes multi-yearly) period is divided into micro and macro cycles, where each microcycle is responsible for the development of a specific (sometimes several) basic training function and parameter, whereas macrocycles are responsible for the development of complex parameters/functions (such as muscle strength).

Heterochronism of supercompensation : Different parameters require different amounts of time to recover after strain. Tendons and bone tissue require considerably longer to adapt than muscle tissue.
