    BACKGROUND: The purpose of this study was to examine tree 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 16:00 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 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.

    The effect of active vs passive recovery and use of compression garments following a single bout of muscle-damaging exercise
    (Ios Press, 2022) Sahin, Fatma Beyza; Kafkas, Armagan Sahin; Kafkas, Muhammed Emin; Taskapan, Mehmet Cagatay; Jones, Andrew Mark
    BACKGROUND: Some recovery strategies are needed to reduce or eliminate the effect of negative symptoms caused by exercise. OBJECTIVE: The aim of this study was to determine the effect of different types of recovery after single-bout strength exercises on biomarkers of muscle damage, cytokine release and lactate elimination. METHODS: Following familiarization, 10 male volunteers performed four randomized recovery protocols (passive or active recovery with or without compression garments) following a single bout of resistance exercise (squat and deadlift exercises). The blood creatine kinase (CK), lactate dehydrogenase (LDH), interleukine-6 (IL-6), and tumor necrosis factor-alfa (TNF-alpha) values were measured before and after exercise, and after 24, 48, 72 hours. RESULTS: The CK analysis showed that all protocols significantly increased (p < 0.05) CK activity compared to the pre and 24 h post time points. Interestingly, protocol 3 and 4 significantly decreased (p < 0.05) CK activity compared 24 and 72 h post-exercise. LDH, IL-6, and TNF values did not show significant difference (p > 0.05) at the time points tested. CONCLUSIONS: Active recovery is an effective method for reducing the severity and duration of muscle damage and for accelerating the clearance of blood lactate (BLa) following a single bout of strength training. There is no added benefit of using compression garments.
