Overtraining (OT) is a complex and multifactorial sport phenomenon, and there is no independent marker that can diagnose OT. Interestingly, some symptoms of OT are related to β-endorphin (β-end1-31) effects. Some of its effects, such as analgesia, increasing lactate tolerance, and exercise-induced euphoria, are important for training. These effects can be reverted by detraining or OT, which may cause decrease in performance, reduced load tolerance, and depression. The main stimulus for β-end1-31 secretion is to exercise because its secretion is volume/intensity dependent for both aerobic and anaerobic exercise. Excess training, however, may reduce β-end1-31 concentrations, thus altering its beneficial effects. Therefore, β-end1-31 could be used as an additional OT marker, mainly because its effects are strongly related to OT symptoms. copyright© ABE&M todos os direitos reservados.
