The Claim

Overtraining syndrome is a pathological condition in athletes caused by a chronic imbalance between training stress and recovery, resulting in persistent performance decrements that last for weeks to months despite rest, and it is positioned on a fatigue continuum that includes acute fatigue, functional overreaching, nonfunctional overreaching, and overtraining syndrome in individuals who train excessively and recover inadequately.

Description
1 study reviewed
In plain English

If athletes push themselves too hard for too long without enough rest, they can develop a serious condition called overtraining syndrome, where their performance gets worse and just won't improve — even after taking time off.

See the scientific wording

Overtraining syndrome is a pathological condition resulting from chronic imbalance between training stress and recovery, leading to persistent performance decrements lasting weeks to months despite rest, and it exists on a fatigue continuum that includes acute fatigue, functional overreaching, nonfunctional overreaching, and overtraining syndrome in athletes who train excessively and recover inadequately.

What the research says

1 study
  1. Study: From Fatigue to Overtraining: Beyond the Dichotomy of Structure and Function

    The study agrees with the claim: when athletes train too much and don’t recover enough, their performance can drop for a long time, and this is part of a bigger pattern of increasing fatigue that can become serious.
