Comparison of chosen physical fitness characteristics of turkish professional basketball players by division and playing position

The purpose of the present study was to compare chosen physical fitness characteristics of Turkish professional basketball players in different divisions (first and second division) and playing positions. Forty-five professional male basketball players (14 guards, 15 forwards, 16 centers) participated in this study voluntarily. For each player, anthropometric measurements were performed, as well as a multi-stage 20 m shuttle run, isokinetic leg strength, squat jump (SJ), countermovement jump (CMJ), 10-30 meter single-sprint and T-drill agility tests. The differences in terms of division were evaluated by independent t-test and the differences by playing position were evaluated by one-way ANOVA with Post Hoc Tukey test. First division players' CMJ measurements were significantly higher than those of second division players' (p≤0.05), whereas second division players' 10 m sprint times were significantly better than those of first division players' (p≤0.05). In addition, forwards and centers were significantly taller than guards. Centers were significantly heavier and their T-drill test performances were inferior to those of forwards and guards (p≤0.05). Moreover, guards had a significantly higher maximal oxygen uptake (VO2 max) than centers. Guards and forwards showed significantly better performance in the 10 and 30 m sprint tests than centers (p≤0.05). Forwards and centers had significantly better left leg flexor strength at 180°.s-1(p≤0.05). In conclusion, the findings of the present study indicated that physical performance of professional basketball players differed among guards, forwards and centers, whereas there were not significant differences between first and second division players. According to the present study, court positions have different demands and physical attributes which are specific to each playing position in professional basketball players. Therefore, these results suggest that coaches should tailor fitness programs according to specific positions on the court. © Editorial Committee of Journal of Human Kinetics

Data mining models for selection of the best spectral reflectance indices in estimation of crop yields and classification of maize hybrid types using spectroradiometer data

2017 European Conference on Electrical Engineering and Computer Science, EECS 2017 --17 November 2017 through 19 November 2017 -- --This study purposes data mining models to estimate the amounts of crop yields using the relationships between the numeric valued crop yield attributes and the numeric valued spectral reflectance indices attributes calculated using different range of canopy reflectance. Data mining models uses knowledge and data technology to find the best spectral reflectance indices subset selection in estimation of crop yields for spectroradiometer reflectance measurements in 220 nm to 1100 nm range. Crop traits are estimated by use of linear regression models as data mining models in terms of computed values of spectral reflectance indices. Data mining classification method with high performance algorithm is used to classify different types of maize hybrids using the numeric valued crop yield attributes with respect to the nominal valued attributes corresponding to different conditions in this study. © 2017 IEEE

PubMed ID: 27511346Background/aim: Broad-spectrum antibiotics have become available for use only with the approval of infectious disease specialists (IDSs) since 2003 in Turkey. This study aimed to analyze the tendencies of doctors who are not disease specialists (non-IDSs) towards the restriction of antibiotics. Materials and methods: A questionnaire form was prepared, which included a total of 22 questions about the impact of antibiotic restriction (AR) policy, the role of IDSs in the restriction, and the perception of this change in antibiotic consumption. The questionnaire was completed by each participating physician. Results: A total of 1906 specialists from 20 cities in Turkey participated in the study. Of those who participated, 1271 (67.5%) had ?5 years of occupational experience (junior specialists = JSs) and 942 (49.4%) of them were physicians. Specialists having >5 years of occupational experience in their branch expressed that they followed the antibiotic guidelines more strictly than the JSs (P < 0.05) and 755 of physicians (88%) and 720 of surgeons (84.6%) thought that the AR policy was necessary and useful (P < 0.05). Conclusion: This study indicated that the AR policy was supported by most of the specialists. Physicians supported this restriction policy more so than surgeons did. © TÜBITAK

Supplementary Material for: A Retrospective analysis of 83 patients with testicular mass who underwent testis-sparing surgery: The Eurasian Uro-oncology Association Multicenter Study*

ABSTRACT Introduction: Herein,we analyzed the histopathological, oncologic and functional outcomes of TSS in patient with distinct risk for testicular cancer. Methods: This is a multicenter retrospective study on consecutive patients who underwent TSS. Patients were categorized in high- or low-risk Testicular Germ Cell Tumor(TGCT) according to the presence/absence of features compatible with Testicular Dysgenesis Syndrome(TDS). Histology was categorized per size and risk groups. Results: TSS was performed in 83 patients(86 tumors) of them, 27 in the high-risk group. Fifty-nine patients had a non-tumoral contralateral testis present. Sixty masses and 26 mases were benign and TGCTs respectively. No statistical differences were observed in mean age(30.9±10.32 years), pathological tumor size(14.67 ± 6.7 mm) between risk groups or between benign and malignant tumors(p=0.608). When categorized per risk groups 22(73.3%) and 4(7.1%) of the TSS specimens were malignant in the high- and low-risk patient groups respectively.Univariate analysis showed that the only independent variable significantly related to malignant outcome was previous history of TGCT. During a mean follow-up of 25.5±22.7 months no patient developed systemic disease. Local recurrence was detected in 5 patients and received RO. Postoperative testosterone levels remained normal in 88% of those patients with normal preoperative level. No ED was reported in patients with benign lesions. Conclusion: TSS is a safe and feasible approach with adequate cancer control and preservation of sexual function is possible in 2/3 of patients harboring malignancy. Incidence of TGCT varies extremely between patients at high and low risk for TGCT requiring a careful consideration and counseling
