Abstract

The overtraining syndrome (OS) reduces the performance of human and equine athletes. It is caused by an imbalance between training sessions and recovery periods. Some studies have used rodents to study the OS and the syndrome may be associated with behavioral, neuroendocrine, and metabolic disorders. Despite the high prevalence in athletes, there are few clinical and laboratory tests available for the prevention and diagnosis of OS. This study proposes to investigate (1) the behavior and (2) muscle biomarkes in Wistar rats that have been experimentally induced to OS on a treadmill. One hundred young male rats weighing between 150 and 250g will be used. The animals are going to be distributed in the control groups (CT), trained (TR), high performance (AD) and low performance (BD). The duration of the OS induction protocol will be 11 weeks distributed in 5 phases. Phases 1 and 2 will consist of a single daily workout. Subsequently, the following phases will consist of increased training intensity and reduced recovery time. Performance tests will be conducted before the training and after the 4th, 8th, 9th, 10th and 11th weeks. Two additional performance tests will be conducted in the weeks of recovery. Rats will be subjected to behavioral tests such as open field and elevated plus maze. Plasma corticosterone and lactate measurements will be performed. Muscle and cardiac biomarkers such as myoglobin, creatine kinase, aspartate aminotransferase, CK-MB and expression of the MCT4 and MCT1 isoforms will also be quantified. For all possible comparisons, the analysis of variance (ANOVA) and the paired and unpaired "Student" t test will be used as needed. (AU)
