Hormonal and biochemical profile in elite sportsmen during the preparation season

Concerns have been raised regarding the effects of short time intensive training on adolescent athletes. The aim of the present study was to investigate six weeks of volleyball training on hormonal and biochemical profile in elite high school male volleyball players in Golestan province (Iran) in pr...

The aim of the present study was to investigate six weeks of volleyball training on hormonal and biochemical profile in elite high school male volleyball players in Golestan province (Iran) in preparation season to take part in global competitions of champion school in France. Subjects of training group consisted of 12 elite volleyball players in premier league students and the control group consisted of 12 healthy and non-athlete boy students. The training group practiced at  60-85% maximum heart rate (MHR) for 6 weeks, 90 minutes per session, 6 sessions per week and 3 sessions a day (first session: technical practice, second session: tactical practices and third session: technical/tactical practices). Blood samples were taken following 12 hours of fasting both before and after the volleyball training. cortisol and lactate dehydrogenase concentrations significantly decreased in the training group following 6 weeks of Preparation training. With the exception of cortisol there was no significant difference between the groups regarding lactate dehydrogenase variable. Glucose concentration significantly increased in the training group following the 6 weeks Preparation training, also significant difference was observed between the control and training group. Testosterone, insulin and insulin resistance levels were increased and cortisol/testosterone ratio was decreased in the training subjects following the 6 weeks of Preparation training (P>0.05). However, the results revealed no significant difference between the two groups regarding these variables. Our results show that volleyball training during the 6 weeks in the preparation season can lead to abnormalities in indices of glucose homeostasis. Also the results suggest that along with the improvement of anaerobic and aerobic characteristics, training reduces the catabolic and inflammatory response to exercise.https://dergipark.org.tr/tr/pub/turkjkin/issue/23846/241661?publisher=turkjkincortisolglucoseinsulininsulin resistancetestestoronevoleyball player
