The Longitudinal Responses of Pulmonary Volumes and Capacities to Serum Cortisol in Young Wrestlers

Authors

Abstract

The purpose of this study was to examine the longitudinal responses of pulmonary volumes and capacities to serum cortisol in young wrestlers. For this purpose, 24 healthy young wrestlers (age 23.9±0.8 years, height 180.64±0.7 cm, weight 76.3±7.3 kg, BMI 23.4±8.5) volunteered to participate in this study. The subjects performed an incremental wrestling training up to 85% of MHR of the training, three times a week for 12 weeks. The pulmonary tests were performed at rest, first six weeks of training (intensity of 75%), second six weeks of training (intensity of 85%), and at the end of a one–week recovery period. Blood samples were collected to measure serum cotrisol by ELISA. The serum cortisol changes during 12 weeks of the high intensity wrestling training significantly affected FIV1 (P=0.001, stage 2), VC (P=0.037, stages 1,2), Tv/Ti (P=0.001, stage 2) so that a change in every unit of cotrisol were accompanied by a significant change in these pulmonary variables. The results of this study suggested that following 12 weeks of high intensity wrestling training, some pulmonary volumes and capacities of wrestlers changed due to the effect of serum cortisol. No such results have been reported so far.
