Öğe Effect of Zinc Supplementation on Antioxidant Activity in Young Wrestlers(HUMANA PRESS INC, 2010) Kara, Ersan; Günay, Mehmet; Cicioğlu, İbrahim; Özal, Mehmet; Kılıç, Mehmet; Moğulkoç, Rasim; Baltacı, Abdulkerim KasımThis study aims to examine the effect of zinc supplementation on free-radical formation and antioxidant system in individuals who are actively engaged in wrestling as a sport. The study registered a total of 40 male subjects, of whom 20 were wrestlers and 20 were sedentary individuals. The subjects were equally allocated to four groups: group 1, zinc-supplemented sportsmen group; group 2, sportsmen group without supplementation; group 3, zinc-supplemented sedentary group; group 4, sedentary group without supplementation. Blood samples were collected from all subjects twice, once at the beginning of the study and once again at the end of 8-week procedures. The blood samples collected were analyzed to determine the levels of malondialdehyde (MDA), serum glutathione (GSH), serum glutathione peroxidase (GPx) activity, serum superoxide dismutase (SOD) activity (ELISA colorimetric method) and zinc (colorimetric method). No difference was found between MDA levels of the study groups in the beginning of the study. The highest MDA value at the end of the study was obtained in group 4 (p < 0.01). MDA levels in group 2 were established to be significantly higher than those in groups 1 and 3 (p < 0.01). GSH level, GPx, and SOD activities and zinc level measured in the beginning of the study were not different between groups. Measurements performed at the end of the study showed that groups 1 and 3 (zinc-supplemented groups) had the highest GSH level, GPx, and SOD activities and zinc level (p < 0.01). These parameters were not different in the groups without supplementation (groups 2 and 4). Results obtained at the end of the study indicate that zinc supplementation prevents production of free radicals by activating the antioxidant system. In conclusion, physiologic doses of zinc supplementation to athletes may beneficially contribute to their health and performance.Öğe Effect of zinc supplementation on lipid peroxidation and lactate levels in rats with diabetes induced by streptozotocin and subjected to acute swimming exercise(COMENIUS UNIV, 2012) Biçer, Mürsel; Günay, Mehmet; Baltacı, Abdulkerim Kasım; Üney, Kamil; Moğulkoç, Rasim; Akil, MustafaObjective: The present study aims to explore the effect of zinc supplementation on lipid peroxidation and lactate levels in rats having diabetes induced by streptozotocin and subjected to acute swimming exercise Method: A total of 80 adult male rats of Sprague-Dawley type were equally allocated to 8 groups: Group 1, general control. Group 2, zinc-supplemented group. Group 3, zinc-supplemented, diabetic group. Group 4, swimming control group. Group 5, zinc-supplemented swimming group. Group 6, zinc-supplemented diabetic swimming group. Group 7, diabetic swimming group. Group 8, diabetic group. At the end of the 4-week study, blood samples were collected to determine MDA, GSH, GPx, SOD, lactate and zinc levels. Results: The highest MDA values were found in group 7 and 8 (p<0.001). GSH values in groups 5 and 6 were higher (p<0.001). The highest GPx values were established in groups 2, 5 and 6 (p<0.001). SOD values were the highest in groups 5 and 6 (p<0.001) and lowest in groups 2, 3 and 8 (p<0.001). The highest plasma lactate levels were found in group 7 (p<0.001). The highest zinc levels were obtained in groups 1,2 and 5 (p<0.001), and the lowest zinc levels were found in groups 7 and 8 (p<0.001). Conclusion: Results of the study reveal that zinc supplementation prevents the increase in free radical formation, suppression of antioxidant activity and muscle exhaustion, all of which result from diabetes and acute exercise. Zinc supplementation may contribute to health and performance in diabetes and acute exercise (Tab. 2, Fig. 1 Ref. 47).

Methods.-Two hundred and eighteen volunteer subjects at the age of 16, namely, 68 soccer players, 89 persons practising fitness and 70 sedentary have participated in the study. In the research, sitting height, crawl length, body width parameters, body environment and sonnatotypic parameters of the subjects are measured. In this work, the highest humeral width value is achieved by the soccer group, where it is found to be no different from the fitness group (P > 0.05) and to be significantly higher than the sedentary group (P < 0.05). When femur width parameter is examined, it is determined that the soccer group is higher than the other two groups and that the fitness group is significantly higher than the sedentary group. In the study, while the highest endomorph value is obtained from sedentary group, it is found to be significantly higher than the other two groups (P < 0.05). While the highest mesomorph value is achieved from soccer group and the lowest value is achieved from sedentary group, it is determined that each of these three groups is significantly different from one another (P < 0.05). While the highest ectomorph value is achieved from fitness group (P < 0.05), it is found to be significantly higher than the other two groups (P < 0.05). Conclusions.-Consequently, it can be said that the soccer players have more optimal dimension, environment and somatotypical structure when compared to those practising fitness and the sedentary group (P < 0.05).

FatihKüresellesme, gün geçtikçe artan uluslararası rekabet ve teknolojideki hızlı gelismeler, hayatın diger alanlarında oldugu gibi çalısma hayatında da bir takım yenilikleri ve degisiklikleri beraberinde getirmistir. Küresellesme, uluslar arası rekabet ve yeni teknolojik gelismeler, isgücüne gereksinimi azaltmıs ayrıca isverenler ve isçiler arasında normal tipteki is iliskilerinden farklı esneklik temeline dayanan yeni tipte is iliskileri ortaya çıkmıstır. Esneklik temeline dayanarak ortaya çıkan yeni tipteki is iliskilerinden bir tanesi de ödünç is iliskisidir. Ödünç is iliskisi; bir isverenin kendisine hizmet sözlesmesiyle baglı isçisini, onun da rızasını almak kosuluyla belirli ve geçici bir süreligine is görme edimini yerine getirmek üzere baska bir isverenin emrine vermesiyle olusan is iliskisidir. Bu tezde 4857 sayılı is Kanunu hükümleri çerçevesinde ?Ödünç iş iliskisi? kavramı ele alınacak ve bu iliskinin kurulması, hüküm ve sonuçlarıyla birlikte açıklanacaktır.Öğe Protective effect of melatonin on lipid peroxidation in various tissues of diabetic rats subjected to an acute swimming exercise(COMENIUS UNIV, 2012) Biçer, Mürsel; Akil, Mustafa; Baltacı, Abdulkerim Kasım; Moğulkoç, Rasim; Sivrikaya, Abdullah; Günay, Mehmet; Akkuş, HasanBackground: The present study aimed to explore the effect of melatonin administration on lipid peroxidation in various tissues of rats with streptozocin induced diabetes and subjected to an acute swimming exercise. Methods: The study used 80 adult male rats, which were equally allocated to 8 groups: Group 1, general control; Group 2, melatonin-administered control; Group 3, melatonin-administered diabetic control; Group 4, swimming control; Group 5, melatonin-administered swimming; Group 6, melatonin-administered diabetic swimming; Group 7, diabetic swimming; Group 8, diabetic control. Diabetic rats were administered 3 mg/kg/day ip melatonin for 4 weeks. At the end of the study, the animals were decapitated to collect samples from liver, lung and spleen tissues, which were then analyzed to determine levels of liver MDA (nmol/gram/protein) and GSH (mg/g/protein). Results: The highest MDA values in liver, lung and spleen tissues were obtained in the Group 7. The values in the Group 8 were lower than those in the Group 7, but higher than in all other groups. The Group 5 and 6 had the highest liver, lung and spleen GSH values. Conclusion: Results obtained from the study indicate that the increase in free radical production and the inhibition of antioxidant activity in diabetes and acute exercise are both prevented by melatonin administration (Tab. 2, Ref. 30).

Gereç ve Yöntem: Araştırmaya, test protokolünün uygulamasını engelleyecek veya kısıtlayabilecek sağlık problemi olmayan, 57'si kadın 50'si erkek olmak üzere toplam 107 kişi gönüllü olarak katılmıştır. Katılımcıların yaş grupları 60-69, 70-79 ve 80 ve üzeri olarak belirlenerek üç grup oluşturulmuştur. Araştırmaya katılan gruplara bazı fiziksel uygunluk testleri ile FPT uygulanmıştır. Bulgular: Verilerin analizi sonucunda; yaşlanma ile birlikte özellikle kadınlarda fiziksel uygunluk değerlerinde anlamlı düşüşlerin olduğu, aynı yaş gurubundaki erkek-kadın karşılaştırılması sonucunda, kan basınçları ile istirahat kalp atım sayıları dışındaki diğer parametrelerde 0.05 anlamlılık düzeyinde genellikle erkek grupların daha iyi olduğu, 70-79 yaş grubu kadınların esneklik değerlerinin ise aynı yaş grubundaki erkeklere göre anlamlı düzeyde yüksek olduğu tespit edilmiştir (p0.05). 80 ve üzeri yaşlardaki kadınlarda toplam FPT puanının diğer yaş gruplarına göre anlamlı derecede düşük olduğu belirlenmiştir (p0.05). Sonuç: Yaş ilerledikçe fiziksel uygunluğa ait yetilerin azaldığı ve bu kayıpların kadınlarda erkeklerden daha fazla olduğu gözlenmiştir.
