Predictive monitorscreen of overtraining by analysis of salivary cortisol, testosterone, IGA and their association with genetic polymorphisms in gymnastics.

It is well known that an excessive physical activity may stress the organism determining unbalanced hormonal orders that can negatively affect the state of optimal health and therefore the sporting output. In particular during physical exercise the serum Cortisol and Testosterone concentrations increase with the intensity of the exercise while IgA levels decrease. On this basis, there is the possibility the determine if the program of preset physical exercise evokes an abnormal reaction of adaptation of the organism. Since physical exercise and athletic performance are strongly related to individual genetic traits, we think that the possibility of customizing the athletic training on the basis both of genetic and of biomarkers involved in physical stress may be a tangible fact. In this study we evaluated the role of several sport-related gene polymorphisms in affecting the physical stress (monitored by salivary biomarkers) during a standard training session. Furthermore we evaluated the feasibility of salivary tests during training session both in terms of athlete’s discomfort both in terms of laboratory quality sample.
