title: Acute physiological changes in elite free-style wrestlers during a one-day tournament.
abstract: BACKGROUND
  The purpose of this study was to examine free radical production, muscle damage and inflammation responses of well-trained wrestlers to a simulated one-day tournament of free-style wrestling.
  
  
  METHODS
  Twelve elite competitive wrestlers with mean age (±SD) of 24.09±6.20 years, body mass 74.09±11.50 kg, and body height 174.90±8.8 cm and who had competed for national teams completed five matches according to the official Olympic wrestling tournament regulations. Blood sampling was collected before and after fifth match. Baseline blood testing was measured at 10:00 a.m. and then matches started at 12:00. Each match was implemented within one hour. Also, the resting time was 45 minutes following each match. The measurements were analyzed by Wilcoxon Signed Ranks Test, which is used to test for significant differences between pre- and post-test.
  
  
  RESULTS
  The post-match lactate dehydrogenase (LDH), creatine kinase (CK), and interleukin (IL)-6 levels were significantly increased compared with the baseline status. However, baseline malondialdehyde levels were not found significantly different compared with post-match.
  
  
  CONCLUSIONS
  The current study ensured that one-day Free-Style wrestling tournament brings about significantly increasing on CK, LDH of muscle damage markers. Also, inflammatory status showed a progressive worsening during the course of one-day tournament. The study showed enhanced muscle damage markers and inflammatory status after one-day Free-Style wrestling tournament. Therefore, it appears that one-day free-style wrestling tournament imposes significant physiological demands on wrestlers that may adversely affect their performance and inflammatory status, thereby putting the athletes in a greater risk for injury.
