Background and objectives: Boxing is a popular combat sport that requires high intensity and cooperation. However, there are limited data about the influence of boxing matches on blood parameters. The purpose of the present study was to investigate the match-induced changes in the metabolic, hormonal, and inflammatory status in male elite boxers. Materials and methods: High-level 20 male boxers with more than 5 years experience in boxing voluntarily participated in this study. Venous blood samples of the boxers, before and after combat, were taken for determination of the plasma parameters. Results: Our results indicated that a 9-min boxing match caused significant increases in plasma energy fuels (glucose and lactate), metabolic hormones (insulin, adrenocorticotropic hormone (ACTH), cortisol, and growth hormone), inflammatory markers (interleukin-1β (IL-1β), interleukin-6 (IL-6) and tumor necrosis factor alpha (TNF-α)), muscle damage indicators (alanine aminotransferase (ALT) and aspartate aminotransferase (AST)), and oxidative stress marker (SOD). A decrease in total oxidant status (TOS) was also considered. However, there were no significant alterations in the plasma levels of androgenic hormone (free and total testosterone), anabolic hormone (IGF-1), lipids (total cholesterol, triglyceride, high-density lipoprotein (HDL), and low-density lipoprotein (LDL)), kidney function markers (creatinine and urea), and minerals (iron (Fe) and magnesium (Mg)). Conclusion: Elevations in the level of energy fuels and metabolic hormones of the boxers could be taken as a reflection of high-energy turnover during combat performance. The increases in inflammatory and tissue damage indicators may possibly be an indication of traumatic injury. Understanding the biochemical changes that occur during boxing match could be valuable to optimize the performance improvement of the athletes.
The aim of this study is to compare according to different positions the mean right and left knee Q angle of footballers and wrestlers. In this study, found the female soccer and wrestlers mean age 20.51 ± 3.47 years, height 165.43 ± 4.82 cm, weight 58.23 ± 5.18 kg. Male soccer and wrestlers has with mean age 21.30 ± 3.45 years, height 173.28 ± 5.45 cm, weight 65.66 ± 5.73 kg. One-way ANOVA, Student t, and Duncan post hoc test were used for statistical analysis. In this study, found that the mean right and left knee Q angles of male athletes were 15.08 ± 1.79° and 14.49 ± 1.82° for the standing position, 14.26 ± 1.84° and 13.29 ± 1.82° for the supine position.The mean right and left knee Q angles of Female athletes were 18.11 ± 1.32° and 17.90 ± 1.35° for the standing position, 17.52 ± 1.36°and 16.82 ± 1.29° for the supine position. In this study, were found abnormal results. The difference between the Q angle values of footballers and wrestlers was found to be statistically significant (p <0.001). The Q angle values for male soccer players were found 15.35 for standing right Q angle and 15.12 degrees for standing left Q angle and same values 14.80 and 13.86 degrees in the male wrestlers. Q angle values for women footballers were found 17.32 decrees for standing right Q angle and 17.22 degrees for standing left Q angle, and same values 18.90 and 18.58 degrees in the women wrestlers. Standing and supine Q angle values of Wrestlers in both men and women were found to be wider than the Q angle values of soccer athletes (p<0.001). The right Q- angle values of the athletes in the standing and supine position were found higher than the left Q-angle values (p <0.05).Conclusion: The Q angles were within the normal range for footballers and wrestlers. In standing positions Q angle is higher than from supine positions Q angle. Athlete's sex, pelvic width, tibia and femur length and dominant foot may increase the quadriceps Q angle.
The aim of this study was to determinate the effects of 12 weeks pilates and aerobic exercise on blood pressure, heart rates, and blood serum lipids in sedentary females. 18 sedentary women with an average age of 45.52 years, height of 161.14 cm and weight of 72.5 kg have been selected and put through a plates and aerobic exercise programmer one hour a day for three days a week. Exercises in each training session were arranged in such a way as to make each woman’s heart rate to reach a level of 130-140 a minute. The waist and hip circumferences were measured using a measuring tape. BMI and waist hip ratio were calculated by standard formulas. Triglyceride (TG), Total Cholesterol (TC), High density lipoprotein (HDL-C) and Low density lipoprotein (LDL-C) levels were determined by Hitachi 717 auto analyzer. Analysis was performed on SPSS 21 version. Paired-t tests were done statistical analysis. Body Weight found before 12 weeks plates and aerobic exercise 72.5 kg and after 63.8 kg. At the end of the 12 weeks exercise program, a decrease of %12.00 in body weight, %14.03 in systolic, %3.96 in diastolic, %13.85 in cholesterol, %25.30 in Triglyceride, and %22.33 in LDL-C have been registered. However, there were increases of %16.34 in HDL-C. The effects of aerobic exercise is on Triglyceride, HDL-C, LDL-C and total cholesterol since (p<0.01). At the end of the 12 weeks exercise program, a decrease %13.34 hip circumference and %4.19 waist circumference. Waist to hip ratio found before 12 weeks plates and aerobic exercise 0.87 cm and after 0.78 cm. The effects of aerobic exercise is on Body weight, Systolic blood pressure, Heart rate, hip and waist circumference since (p<0.05; p<0.01). In this study, together Pilates and aerobic exercise was effective in sedentary women with initially high total cholesterol, triglyceride, and Low density lipoprotein levels. At end of the cycles of 12 weeks Pilates and aerobic exercises, has a positive effect of waist to hip ratio, blood pressure, and heart beats in sedentary females. Risk of heart and vascular disease is reduced. Pilates and aerobic exercises are recommended for decrease risk.
