Physiological responses to detection overtraining

Abstract

The excessive exercises allied with inadequate recovery periods can result in the overtraining which is characterized by a series of disturbs in metabolic and physiological parameters associated to a reduction on performance. The overtraining can be controlled by innumerous biomarkers that enable the real state of athlete. However, to characterize the overtraining is important that these biomarkers as hormonal, biochemistry, metabolic, VO2 max and heart variability be associated with declining in performance. Clinical test is important to diagnostic, to prevent and to treat the overtraining. Although there are many studies on overtraining, there are still contradictions in the literature about the best indicator. Thus, the aim of this review is to expound the main physiological responses caused by overtraining to researchers, trainers and athletes deepen their knowledge on the way to detect overtraining caused by inadequate program of training.
