CHANGES IN SALIVARY CORTISOL LEVELS DURING SHORT-LASTING PRE- AND POST-CONTEST PERIOD IN MALE WRESTLERS
Journal Title: Medycyna Sportowa - Year 2009, Vol 25, Issue 6
Abstract
[b]Background.[/b] Studies on changes in cortisol levels in biological fluids; blood, saliva or urine are useful for estimation psychological or physical stress in humans. This study aimed to evaluate the behaviour of salivary cortisol prior to wrestling contests and during short-term post contests recovery.[b]Material and methods.[/b] Polish wresters (n=16) were examined during various occasions, once at rest condition, and twice during two-day Tournament. Saliva samples for determination of cortisol levels were taken at rest, before routine training session (-5 minutes), and before (-20, -5 min) and after (+5, +20 min) the first eliminatory (on the first day), and first final (on the second day) contest of an International Wrestling Tournament. The hormone was measured with using commercial kit.[b]Results.[/b] The mean basal cortisol level was significantly (p<0.005) lower than those recorded at all time points during competition. Post-contests cortisol levels within +5 and +20 min. were significantly (p<0.05) higher compared with those pre-exertions. Within short lasting period before contests, from -20 to -5 min, mean cortisol increased significantly (p<.0.01). Cortisolism expressed as area under curve (-20, -5, +5, +20) was significantly higher (p<0.01) on the second day of competition. Peak of cortisol appeared at +20 min of recovery.[b]Conclusions.[/b] Anticipation of an official, athletic combat is the main reason for higher cortisol prior to competition than to routine training. During short-lasting period directly prior to contests cortisolism elevated with time-to-event. We assume, that stronger anticipation of final combat against opponents of higher skills resulted in higher pre-event mean cortisol.
