RESUMO
OBJECTIVES: The aim of this study was to present the somatotype features of young individuals without any symptoms and to identify whether isokinetic knee muscle strength and dynamic balance scores are affected by somatotype difference. PATIENTS AND METHODS: A total of 146 participants (88 males, 58 females; mean age 22.5±1.9 years; range 19 to 28 years) who had no symptoms were included in this study. Somatotypes of the participants were calculated using the Heath-Carter formula, and anthropometric measurements were taken from each participant. Knee flexion and extension muscle strengths at angular speeds of 90°/sec, 120°/sec and 150°/ sec were measured from the dominant and non-dominant limbs of the participants. Total balance, anterior/posterior balance, and medial/ lateral measurements were made to evaluate dynamic balance performances. RESULTS: Six different somatotypes were found. Endomorphic mesomorph was the most common somatotype in 56 participants. There was no significant somatotype difference in men and women for dominant and non-dominant knee extension and flexion peak strength values at angular speeds of 90°/sec, 120°/sec and 150°/sec (p>0.05). No significant difference was found between the balance scores of men and women who had different somatotypes (p>0.05). CONCLUSION: Anatomic structure of the body, which is suitable for the sports branch, has an increasing effect on performance.
RESUMO
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.
