The objective of the current study is to determine the effects of regular wrestling exercise oxidative DNA damage and antioxidant parameters. The findings of the current study have shown that 8-hydroxy-2’-deoxyguanosine (8-OHdG) obtained from wrestlers in basal status were significantly lower than those of sedentary (p = .001). In contrast, Nitric oxide (NO) and Paraoxonase-1 (PON1) were remarkably higher in wrestlers in basal status than those of sedentary (respectively, p = .001, p = .024). While the NO of wrestlers increased immediately after a 1.5-h exercise compared with those before exercise (p = .002), no differences was found between before and immediately after a 1.5-h exercise in 8-OHdG and PON1 (respectively, p = .777, p = .408).Statistically significant correlations were found between the NO and PON1 in the wrestlers in basal status (r = .671, p = .002). In conclusion, our study suggests that wrestling exercise for a healthy life is important in that it reduces DNA damage as well as enhancing antioxidant parameters.

This study aims to investigate the effects of different levels of royal jelly supplementation on biochemical parameters in swimmers. Randomly selected 40 male swimmers aged 18 to 25 years attending the same trainings were recruited. Swimmers were assigned to 4 groups each with 10 subjects. Varying amounts of royal jelly (2, 1 g and 500 mg) were given to the 1st, 2nd and 3rd groups and placebo (corn starch) to the 4th group. Participants were trained by swimming totally 20 km in 2 h on 5 days a week for 4 weeks. Resting blood samples were taken before royal jelly administration and after 30 days of application. Then biochemical analyses were performed. Different levels of royal jelly were found to be ineffective on glucose, total cholesterol, high density lipoprotein (HDL) cholesterol, low density lipoprotein (LDL) cholesterol, lactate dehydrogenase (LDH), creatine kinase (CK), aspartate aminotransferase (AST), alanine aminotransferase (ALT) levels of the swimmers. Blood urea nitrogen (BUN) and creatinine levels increased after the training program, and BUN level was higher in the group receiving 500 mg royal jelly than those in the other groups. The increment in creatinine levels was higher in those groups receiving higher amounts of royal jelly after the training. A supplementation of 500 mg, 1 and 2 g/day of royal jelly throughout the 30 day-exercise program was not significantly effective in the swimmers. Also, due to its high amino acid content, BUN and creatinine levels tended to increase. Key words: Royal jelly, swimming, exercise, biochemical parameters, ergogenic aids.

The aim of this study was to investigate the effects of 12 min run test on oxidative stress, some antioxidant enzyme activities, and muscle and DNA damage. Twenty two healthy and well trained male athletes were recruited to this study. The12 min run test, cooper test, was applied to the participating athletes. The blood samples were taken before, immediately after and 24 h after the run test, and sera and plasma were separated and then stored at –80°C until the analysis. Serum MDA and NO levels as the indicators of oxidative damage; serum SOD and CAT, plasma GPx activities as the indicators of antioxidant defense system; serum 8-OHdG as the indicator of DNA damage, CK and LHD enzyme activities as the indicators of muscle damage, and glucose level were measured. Serum SOD, NO, CAT, and 8–OHdG levels showed no significant changes before, immediately after and 24 h after the run rest. There was a significant decrease in serum MDA level immediately after exercise, which is returned to baseline level after 24 h–rest period (p<0.05). Serum LHD (p<0.001) and CK activities (p<0.05) and glucose level (p<0.001) increased immediately after exercise but these increments returned to pre-exercise level after 24 h–rest period. Acute twelve minute endurance exercise increased CK, LDH and glucose decreased oxidative stress and whereas has no effect on antioxidant capacity and DNA damage in trained young men. Key words: Antioxidant enzymes, exercise, oxidative stress, twelve minute run test.

Background and Study Aim: Among products used as ergogenic substances by sportsmen, royal jelly and honey have attracted attention in recent years. This study was carried out to determine the effect of royal-jelly and honey mixture on weight lifting performances and some hormone test of athletes. Material and Methods: Randomly selected healthy 29 athletes, aged between 20 and 25 years, were divided into two groups. Placebo (corn starch) was given to the Control Group and 5 grams of royal jelly + 45 grams of honey mixture was given to the experimental group for eight weeks. After one week of weight adjustment workout; maximum weight (bench press, shoulder press, squat, deadlift and arm curl movements) that each athlete can lift was determined and hormones (Free T4, Free T3, Cortisol, Insulin, Total Testosterone and ACHT, TSH, Growth Hormone, Prolocatin, FSH, LH) were examined at pro-exercise, after four weeks of exercise, and after eight weeks of exercise. Results: As a result of the study, a statistical increase in the weights lifted in the bench press, squat, arm curl, deadlifts and shoulder press movements in the second and third measurements with respect to the first measurement was determined within both groups (p 0.05), but there was significant difference in free T4 value in 2. measurements of groups (p = 0.030) and between the 2. and 3. measurements in the test group in the variable of insulin hormone (p <0.001). Conclusions: In conclusion, it is thought that in young males performing maximal strength workout, royal jelly + honey supplement does not affect the increase in weight lifted, this increase is due to the weight training applied, but it causes some hormone changes.

Bu çalışmada, düzenli olarak eğitsel oyunlara katılan 7-8 yaş erkek ilköğretim öğrencilerinin, denge, reaksiyon süresi ve çeviklik değerlerinin incelenmesi amaçlanmıştır. Çalışmaya, Kayseri Kızılören Osman Kulaç İÖO’daki, 7-8 yaşlarda 28 erkek öğrenci gönüllü olarak katıldı. Deney grubunu oluşturan 14 öğrenci eğitsel oyun faaliyetine katılırken, kontrol grubunu oluşturan 14 öğrenci eğitsel oyunlar faaliyetine katılmadı. Katılımcıların, el ve ayak reaksiyon testi reaksiyon cetveli ile, denge testi flamingo denge aleti ile ve çeviklik testi fotosel ile ön testleri testleri yapıldı. Sekiz hafta sonra, haftada üç gün eğitsel oyunlara katılan deney grubu ile kontrol grubunun son test ölçümleri yapıldı. Elde edilen veriler aritmetik ortalama ve standart sapma olarak sunuldu. Bağımsız grupların karşılaştırılmasında indepedent sample t test ve bağımlı grupların karşılaştırmasında paired sample t test kullanıldı. Anlamlılık düzeyi p<0.05 olarak alındı. Deney ve kontrol grupları arasında son test ölçüm sonuçlarına göre el reaksiyon, ayak reaksiyon, denge ve çeviklik test değerleri arasında istatistiksel olarak anlamlı farklılıklar görülürken (p0.05). Deney grubunun test öncesi ve sonrası el reaksiyon, ayak reaksiyon, denge ve çeviklik test değerleri arasında istatistiksel olarak anlamlı farklılıklar görülürken (p0.05). Eğitsel oyunlara katılımın, 7-8 yaş çocuklarda el ve ayak reaksiyon sürelerinde, denge ve çeviklik üzerine olumlu etkileri olduğu görüldü. Eğitim kurumlarının çocuklara yönelik eğitsel oyun faaliyetlerinin belirlenmesi, belediyelerce ilköğretim öğrencilerinin eğitsel oyun oynayabileceği parklar yapılması ve okul çağındaki çocukların mümkün olduğunca eğitsel oyun faaliyetlerine katılması önerilmektedir.

The present study is aimed at comparing the effects of ice massage versus cold-water immersion on creatinekinase (CK) levels and delayed-onset muscle soreness (DOMS) values of elite wrestlers. To achieve the objectives of the research twenty elite wrestlers participated in the study. Participants were separated into two groups (ice massage vs. cold water immersion) of whose weights were equal. Between the sets, experiment group was applied ice message for 8 minutes while control group was given cold-water immersion. Blood samples of the subjects were taken before and after the exercises. Groups’ differences were determined with “Repeated Measures Analysis of Variance”. Significant differences were observed within both groups at all times (0.05). Including competition and training for athletes, ice massage as a recovery strategy is expected to shorten the recovery time in athletes.
