Methods: Students (n=217) observed an experimental study on frog heart and they prepared an observation report at the end of this practice. Other students (n=196) watched the video recordings of the same experiment. They also prepared an observation report. Grades were given from the reports. All students were answered a Likert type questionnaire about what they learnt one year after the practice. The answers were compared in two groups by Mann Whitney U test and Chi-squire test. Results: No difference was determined between the answers about to understand the cardiac function (p=0.980), the effects of ions on cardiac function (p=0.709), knowledge about pace makers and conduction system of the heart (p=0,474) in two groups. Grades were higher for the students who were watched the video recording...

Method: Sixteen inactive medical faculty students aged 18-24 years old were participated voluntarily in this study. Participants were separated in two groups as oral exercise education (OE) or applied and oral exercise education (AOE) groups. Physical activities were recorded during seven days following the measurement of maximal oxygen consumption (VO2max). OE was given during 30 minutes in both groups. Applied education was done during 15 minutes in AOE group. Recording of physical activity before and after education were compared in groups. Results: Mean age, BMI and VO2max levels were similar in two groups. Daily energy expenditure was higher when compared during three days before and after education in AOE group (428,1 (345,8-476,6) vs 525,8 (382,8-637,8) Kcal/day, p=0.01). Increased daily step count has b...

The role of voluntary physical activity in these alterations is not known clearly. The aim of this study was to investigate the possible improving effects of voluntary physical activity in rats that were feeding with a fructose-rich diet. Spraque-Dawley female rats were separated as control (C;n=7), voluntary physical activity (A;n=7), fructose (F;n=7) and fructose+activity (F+A;n=7) groups. A and FA groups were kept in cages with running wheels during six weeks. F and FA groups were fed with adding 20% fructose in drinking water. Body weight was measured weekly and Lee Index was used to determine obesity. At the end of the feeding period serum glucose, insulin and lipid levels were measured by enzymatic method and blood pressure was determined with the tail-cuff method. Daily voluntary walking distance in F+A and A groups were ...

They have filled out Exercise Dependency Scale-21 and by dint of the scale they have been categorized into 3 following groups: “Dependent”, “Non Dependent Symptomatic” and “Non Dependent Asymptomatic”. The participants’ medical conditions and traits of cycling were determined by an evaluation form and compared in between the groups. For the data acquired, Kruskal Wallis test was used for the comparison in between the groups; Mann-Whitney-U test was used to compare the data of two groups. This study was approved by the local ethics board. Results: When the data analyzed with Exercise Dependency Scale-21, it was determined that there were 9 (5.5%) people who were “dependent”, 107 (67.8%) people who were “non dependent symptomatic” and 49 (29.7%) peopl...

We aimed to investigate the effect of a high-fructose diet (HFD) on GLUT5 and AQP7 levels in the rat heart subjected to exercise. Male Sprague-Dawley rats were allocated to control (C; n=11), exercise (E; n=10), HFD (n=12), and HFD plus exercise (HFD-E; n=12) groups. HFD was started 28 days before euthanasia. From day 24 to 27, rats were subjected to moderate exercise, followed by vigorous exercise on day 28 (groups E and HFD-E). Cardiac GLUT5 and AQP7 mRNA levels were determined using RT-PCR. The protein contents of GLUT5 and AQP7 were immunohistochemically assessed. Paired-t, ANOVA with Bonferroni, Kruskal-Wallis, and Bonferroni-corrected Mann-Whitney U tests were used for statistical analysis. GLUT5 mRNA expression and protein content did not differ between the groups. AQP7 mRNA levels significantly increased (4.8-fold) in gro...

A total number of 224 female athletes from Edirne city participated in our study. Eating attitudes test (EAT 40) and a self-administered questionnaire were used to assess disordered eating behavior and menstrual status respectively. The participants having both disordered eating and amenorrhea were performed dual energy x-ray absorptiometry to evaluate bone mineral density. Thirty seven subjects (16.8%) had disordered eating behavior and 22 subjects (9.8%) were reported to have amenorrhea. Six athletes (2.7%) met two criteria (disordered eating and amenorrhea) of the triad. Of these, only three athletes met all components of the triad. We have found that the prevalence rate of female athlete triad was 1.36% among young Turkish female athletes. Fe...

Eight female (age = 16.2 ± 1.1 yrs) and 8 male (age = 17.3 ± 0.9 yrs) wrestlers from the Turkish cadet and junior national team participated in this study. Fat free mass (FFM) and percent fat mass (%FM) were carried out through electric bioimpedance. Anaerobic performance was assessed by the Wingate test (load was calculated as 0.090 kg x.kg(-1) body mass). FFM was greater in male wrestlers [65.4 ± 12.3 (kg)] than female wrestlers (45.1 ± 4.6 (kg) p < 0.01). %FM was lower in male wrestlers (9.7 ± 6.3) than female wrestlers (18.5 ± 2.8; p < 0.01). Peak power was significantly higher in male wrestlers than female wrestlers (8.5 ± 1.0 W·kg(-1) vs. 6.8 ± 0.6 W·kg(-1); p < 0.01). Mean power was significantly correlated with FFM in both genders (r = 0.73 p < 0.05 in female; r= 0.90 p < 0.05 in male). No relationship was obtained b...

Thirteen volunteer male physical education students completed the Turkish version of State Anxiety Inventory and performed Wingate anaerobic test for three times: (1) following a full-night of habitual sleep (baseline measurements), (2) following 30 hours of sleep deprivation, and (3) following partial-night sleep deprivation. Baseline measurements were performed the day before total sleep deprivation. Measurements following partial sleep deprivation were made 2 weeks later than total sleep deprivation measurements. State anxiety was measured prior to each Wingate test. The mean state anxiety following total sleep deprivation was higher than the baseline measurement (44.9 ± 12.9 vs. 27.6 ± 4.2, respectively, p = 0.02) whereas anaerobic performance parameters remained unchanged. Neither anaerobic parameters nor state anxiety levels were affected by one night partial sle...

The study population consisted of 22 non-smoker subjects divided into two groups. First group comprised 12 patients (4 male, 8 female, mean age: 48±4 years, range 36 to 65) with SX. Ten healthy subject (4 men, 6 female, mean age: 45±3 years, range 34 to 58) were served as control group. Volumetric pulmonary functions, including DLCO were also performed before lung scintigraphy. Alveolar epithelial permeability was assessed by measuring the pulmonary clearance of an inhaled (99m)Tc-DTPA using a gamma camera. Spirometric data was comparable in both groups. Although volumetric pulmonary measurements were similar, DLCO values of SX patients were l...

The QT and JT intervals are measured to estimate the duration of the ventricular repolarization. As new repolarization parameters, the time intervals between the J point to the apex of the T wave (JTa), the apex and the end of T wave (TaTe) may be associated with arrhythmogenesis in clinical conditions. The aim of this study was to compare ventricular repolarization parameters in overweight and normal weight healthy young men. Thirty-six overweight men (BMI--26.3+/-1.5 kg/m2, mean age--20.6+/-1.5 years) and 149 men within normal limits (BMI--21.9+/-1.5 kg/m2, mean age--20.4+/-1.4 yrs) were included in this cross-sectional controlled study. The body mass index of 25 to 29.9 kg/m2 was defined as overweight and scores of 18.5 to 24.9 kg/m2 were accepted as normal. Ventricular repolarization parameters including QT, JT, JTa, TaTe, RR intervals duration and heart rate-correcte...
