Background. The aim of ­this ­study was to inves­ti­gate the ­acute hor­mo­nal ­response of tes­tos­te­rone, ­free tes­tos­te­rone, cor­ti­sol and ­free tes­tos­te­rone: cor­ti­sol ­ratio to 2000 ­metre row­ing ergom­e­ter dis­tance in high­ly ­trained ­male row­ers.
Methods. Twelve ­male nation­al stan­dard row­ers (age 20.5±3.0 ­years, ­height 187.9±6.1 cm, ­body ­mass 87.1±8.3 kg, per­cent ­body fat 10.4±3.2%) ­took ­part in ­this inves­ti­ga­tion. The row­ers ­were ­asked to cov­er 2000 ­metre row­ing ergom­e­ter dis­tance as ­least ­time as pos­sible and the ­blood was col­lect­ed ­from anti­cu­bi­tal ­vein ­before, imme­di­ate­ly ­after and 30 min ­after exer­cise. Testosterone, cor­ti­sol and sex hor­mone bind­ing glob­u­lin ­were meas­ured and ­free tes­tos­te­rone and the ­free tes­tos­te­rone: cor­ti­sol ­ratio cal­cu­lat­ed.
Results. Immediately ­after the exer­cise, tes­tos­te­rone, cor­ti­sol and ­free tes­tos­te­rone ­were sig­nif­i­cant­ly ­increased, ­while ­free tes­tos­te­rone: cor­ti­sol ­ratio ­remained ­unchanged. Thirty min­utes ­after the exer­cise a fur­ther sig­nif­i­cant ­decrease in tes­tos­te­rone and ­free tes­tos­te­rone: cor­ti­sol ­ratio, ­increase in cor­ti­sol and no ­change in ­free tes­tos­te­rone val­ues ­occurred. Free tes­tos­te­rone: cor­ti­sol ­ratio was sig­nif­i­cant­ly relat­ed to the ­time (r=-0.65) and ­mean pow­er (r=0.66) of 2000 ­m row­ing ergom­e­ter ­race. In addi­tion, the ­increased post­ex­er­cise cor­ti­sol con­cen­tra­tion was sig­nif­i­cant­ly relat­ed to 2000 ­m row­ing ergom­e­ter per­for­mance ­time (r=0.63) and ­mean pow­er (r=-0.64).
Conclusions. The ­results of our ­study sug­gest ­that the rel­a­tive­ly ­short ­high inten­sity row­ing exer­cise sig­nif­i­cant­ly chang­es the ana­bol­ic and cat­a­bol­ic hor­mone lev­els in high­ly ­trained ­male row­ers. Rowing ergom­e­ter per­for­mance is sig­nif­i­cant­ly relat­ed to the post­ex­er­cise ­free tes­tos­te­rone: cor­ti­sol ­ratio.
