Journal Title: Medycyna Sportowa - Year 2016, Vol 32, Issue 1
Abstract
[b]Background. [/b]Competition in the sport of modern pentathlon lasts the whole day, from morning to evening, and comprises of four successive events. This study aimed to explore changes in blood cortisol (C), testosterone (T), growth hormone (GH) and lactate (La) levels triggered by the prolonged competitive stress in male and female athletes.[b]Material and methods.[/b] Four male and four female Polish competitors participated in an international tournament of modern pentathlon. Capillary blood was drawn before and after the fencing, swimming, combined event and riding events. Plasma C, T, GH and La were subsequently determined. Ratings of perceived exertions were also declared after the fencing, swimming and combined events.[b]Results.[/b] The female competitors demonstrated significantly higher mean levels of C and GH, but similar La responses in comparison to their male counterparts. Each type of event triggered an acute rise in C and GH. In males, T tended to decrease over time and female T levels did not show this change. Excluding early morning hours, C levels remained high across the day and did not show any diurnal rhythm. Post effort La levels indicated that the most intensive efforts were swimming and combined event.[b]Conclusions.[/b] Participation in a modern pentathlon competition (lasting the whole day and consisted of several efforts) led to modifications in the hormonal and metabolic status in male and female athletes. Sexual dimorphism was also demonstrated, as indicated by different behaviors in C, T and GH.
