    Foot morphology of Turkish football players according to foot preference
    (ACADEMIC JOURNALS, 2011) Yamaner, Faruk; Karacabey, Kursat; Kavlak, Yasemin; Sevindi, Tarik
    Football is the most popular sport in the world. Foot morphology and foot preference are important factors in football player's performance. The aim of this cross-sectional study was to evaluate the foot morphology of elite football players with different foot preferences. 407 male football players participated in this study. 328 of them preferred their right foot, while 79 of them preferred the left one. Eleven anthropometric measurements were taken from each foot with standard anthropometric methods. Foot length, T1, T2, T3, T4 and T5 lengths, foot circumference of right and left feet and right foot width of right foot preference group were higher than those of left foot preference group, which is statistically significant (p < 0.05). Left foot measurements of right foot preference group were interestingly higher than those of the right side. It was suggested that these data may be useful to define the foot morphology of elite football players.

    Protective role of melatonin on blood parameters following irradiation in rat
    (ACADEMIC JOURNALS, 2011) Ozmerdivenli, Recep; Karacabey, Kursat; Gundogdu, Cemal; Sevindi, Tarik
    The aim of this study was to determine the preventive role of melatonin on several blood parameters after irradiation exposure in rats. A total of 100 adult Wistar albino rats were divided into five groups. One group was used as control and other groups were treated with 60, 90, 120 and 160 cGy/min of radiation, respectively. A dose of 4 mg/kg of melatonin was administered subcutaneously to 10 rats from each group exposed to different amounts of radiation. Saline was administered to 10 rats from the control group. 20 days after the completion of the 10-day experiment, the rats were sacrificed and blood samples were collected for determination of erythrocytes, leukocytes, hemoglobin, hematocrit and thrombocyte levels. In the group that received 60 cGy-radiation, the number of erythrocytes were similar to the control group, whereas the leukocyte and thrombocyte counts were increased. In the 90 cGy-radiation exposed rats, erythrocytes, hemoglobin and hematocrit values were low as compared to the controls. In the 120 to 160 cGy-radiation treated rats, leukocyte, hemoglobin, hematocrit and thrombocyte numbers were significantly different from the control groups (P<0.01). In the radiation-melatonin administrated rats, no difference was seen in the blood parameters as compared to the control group, except for the thrombocyte numbers. The thrombocyte numbers in all experimental groups were significantly higher than the controls (P<0.05). Melatonin was effective to reverse the deleterious effects of radiation on the blood parameters in rats and this effect was found to be dose-dependent.

    Some cellular immune components and C-reactive protein monitoring in female handball players during a competitive period
    (ACADEMIC JOURNALS, 2011) Sevindi, Tarik; Hazar, Serkan; Ibis, Serkan; Gokdemir, Kadir
    The aim of the study was to determine the effect of the competitive period training on leukocytes, some leukocyte subgroups and C-reactive protein (CRP) in sportswomen playing in the professional handball league. The average age of the group was 20.6 +/- 3.37 years, height average was 163 +/- 6.30 cm, weight average was 58.73 +/- 4.92 kg. Blood samples were taken before and after the training period of the competition. Subjects rested for 48 h until taking blood samples. Subsequently, leukocytes, some leukocyte subgroups and CRP were determined. Leukocytes and leukocyte subgroups were determined using a Roche Sismex 2000XL device. CRP was determined using Beckman immunochemistry systems in-vitro diagnostic kits and nephelometric methods (Beckman Coulter Array 360 System, USA). Statistical analysis was performed using a paired t-test. p values <0.05 were considered statistically significant. In this study no significant difference was found on WBC and granulocyte values between pre and post training period. However, significant differences in lymphocyte values were measured. After training period, lymphocytes declined (p<0.05), but no significant differences in monocyte levels were determined. CRP values after the training period were significantly decreased (p<0.05), as compared to pre training values. We can conclude that competition period training did not significantly affect the cellular immune elements, but caused a significant decrease on CRP values, which are markers in chronic inflammation.

    The effects of nutrition habits of secondary school students on their educational status
    (SILA SCIENCE, 2012) Sevindi, Tarik
    This study has been conducted to illustrate the improper food habits and its effects on school success among 250 secondary school students. Cognitive development of the children is affected from genetic and environmental factors. The potential of the cognitive development of children is genetic but it has been determined that sufficient nutrition and rich stimulants have positive effects on cognitive development. The factors such as nutrition, education, genetic, environmental factors, and illness prevalence are the elements that affect the growing and subsequent life of the children. The new studies on neurotic behaviors and human growing showed that nutrition has important effects on physical, sensoral, and cognitive development of the children. To determine the secondary school students' personal and nutritional features, we used The Statistical Packet for the Social Sciences (SPSS) 17.0 packet program. We used number and percentage to understand if there is a difference between the nutrition habits and socio-economic factors of the students, and chi-square test to determine the difference between two independent groups we used independent samples "t" test. As a result nutrition education should be considered as one of the elements of formal and common-public education. The affect of adequate and well balanced nutrition cannot be denied. The best indicator of the effect of adequate and balanced nutrition on learning is not to avoid or to pass the breakfast. Especially habit of having breakfast should be given to the children and schools should have breakfast programs. It can be said that to achieve the best quality in basic education, adequate and well balanced nutrition has a great effect on brain development and cognitive functions.
