This study investigated athletic performance and homocysteine (Hcy) levels in relation to the methylenetetrahydrofolate reductase (MTHFR) C677T mutation and explored the relationship between this mutation and other cardiac risk factors in soccer players and sedentary individuals. The study groups consisted of randomly selected soccer players (n=48) from the Turkish Super and Major League and sedentary male students (n=48) aged 18-27. Anthropometric variables, aerobic and anaerobic thresholds were measured, furthermore, biochemical assays were performed. The level of HDL cholesterol, LDL cholesterol, triglyceride, Hcy, folate, vitamin B12, hemogram and MTHFR C677T was investigated. The results showed that there was a statistical difference between the two groups in terms of body mass, body fat, the BMI, the aerobic threshold heart rate (ATHR), aerobic threshold velocity (ATVL) and anaerobic threshold velocity (ANTVL). The soccer players were found to have lower levels of triglyceride, total cholesterol and LDL cholesterol, and higher levels of folate than the sedentary participants. The analysis of the alleles of the MTHFR C677T polymorphism showed that the participants that carried TT genotypes had a lower level of vitamin B12 and folate, and a higher level of Hcy than the participants carrying CC and CT genotypes. In conclusion, the baseline homocysteine and cardiovascular fitness levels of healthy young males with the TT genotypes of the MTHFR C677T genotype were found to strongly correlate with their levels of Hcy.

Objective: The purpose of this study is to investigate effects of resistance training on IL-6, IL-8, TNF-α, blood hematocrit and cortisol levels. Materials and Methods: Thirteen players from Manisa Celal Bayar University soccer team and 14 sedentary male students were used as the study subjects. The subjects, whose average age was 18-24 years old, were healthy and free of any cardiovascular diseases. Anthropometrics measurements and blood samples were obtained from all the subjects. Blood samples were obtained basal sample (before the exercise), immediately after the training program (post-exercise), and 2 hours after the training program (2h post-exercise). All subjects participated in the training program in which intensity prescribed individually in 10 different exercises; seated leg press, knee extension, knee flexion, chest press, chest flys, lat pull down, shoulder press, triceps extension, biceps curl and sit-ups. Three sets of intensity of the each exercise were arranged according to pyramidal system at 70-80 % of the each participant. The volume of resistance training was 50-60 minutes. Results: Post exercise IL-6 (p= 0,05) and IL-8 (p= 0,04) concentration of athletes were statistically lower compared to that of sedentary group. Furthermore, serum cortisol concentrations were found to be decreased in both study groups in post exercise and 2h post exercise samples compared to basal values (p<0,05). Post exercise IL-8 (p=0,04) and TNF-α (p=0,04) values of sedentary group increased significantly compared to values at 2h post exercise. Conclusion: IL-6, IL-8, and TNF-α responses to resistance training vary depending on the recruitment of different muscle fiber types by the trained individuals during the resistance training and the recovery of glycogen storage, which is found to be different from that of sedentary individuals.

A AB BS ST TR RA AC CT T: : O Ob bj je ec ct ti iv ve e: : This study was aimed to investigate the relationship between anthropometric, physical, technique components and three agility tasks; planned (PAT), unplanned (UNAT) and unplanned soccer specific reactive agility test (USRAT). Eighteen sub-elite soccer players (age 18±1.28 years) attended to the this study. M Ma at te er ri ia al l a an nd d M Me et th ho od ds s: : Anthropometric measurements, linear sprint speed tests (10m static sprint, flying 20m sprint), leg muscle strength tests (depth jump, isokinetic strength test), and running technique tests (zig-zag test) were performed. Planned agility, unplanned agility and agility with one unplanned change of direction with dribbling were used to evaluate agility performances. To investigate the relationship between PAT, UNAT, USRAT and anthropometric, physical, technique components; Pearson or Spearman correlation analysis were used depending on normal distribution. R Re es su ul lt ts s: : Static 10m sprint and PAT showed a statistically significant correlation (r=0.604). UNAT was significantly correlated to flying 20 m test (r=0.513). None of drop jumps components had significant correlations with the agility tests (p>0,05). Moreover, USRAT showed statistically significant correlation (r=-0.502), (p<0.05) with the number of steps taken at the turn movement and no significant relationship with isokinetic variables (p>0.05). C Co on nc cl lu us si io on n: : In conclusion, if a soccer-specific task is involved in an agility test, it may be reported that the performance is most likely to be affected by player's technical skill. Moreover, the results of running technique analysis indicate that to be better at agility task players have to be better at making decisions instead of getting closer to the ground at the turning movement.K Ke ey yw wo or rd ds s: : Planned agility; reactive agility; running technique; soccer Ö ÖZ ZE ET T: : A Am ma aç ç: : Çalışmanın amacı, antropometrik, fiziksel, teknik bileşenler ile önceden planlanmış (ÖPÇT), önceden planlanmamış (PÇT) ve futbola özgü reaktif çeviklik testi (FÖRÇT) arasındaki ilişkiyi incelemektir.
