No abnormal results were found in this study. The mean right and left knee Q-angle values of male and female athletes were negatively correlated with femur bicondylar diameter, trochanter diameter, body weight, body height, and calf circumferen...

Bireysel sporlarla uğraşan yıldızlar kategorisindeki sporcuların solunum fonksiyonlarının karşılaştırılması

Objectives: It was aimed to research pulmonary functions of sedentary males and athletes who engaged in different individual sports branches in the same age group. Methods: 50 male athletes in 15-16 age group in the star category participated from each of the branches of judo, athletics, wrestling, taekwondo, table tennis and swimming and 50 sedentary males participated as well; being in total 350 subjects. Among respiratory functions tests; vital capacity (VC), forced vital capacity (FVC) and maximum voluntary ventilation (MVV) values were measured. Results were compared. Results: As a result of measurement, VC values of wrestlers, swimmer and taekwondo athletes were significantly higher than the values of sedentary males in statistical size (p<0.05 and p<0.01). VC values of swimmers were significantly higher than athletes of judo, track and field and table tennis athletes (p<0.01). It was determined that FVC and FEV1 values of swimmers and wrestlers have significantly higher values than sedentary subjects (p<0.05). FVIC values of swimmers were significantly higher than athletes, table tennis players and sedanters (p<0.05 and p<0.01). MVV values of swimmers were significantly higher than judo, track and field and table tennis athletes (p<0.05). When the respiration rate (RR) was analyzed, RR value of table tennis players were significantly higher than wrestlers (p<0.05). Conclusion: As a result it was determined that respiratory functions were higher among subjects who do exercise compared to those who do not. That the respiratory parameters of athletes doing exercise from different branches of star category are higher than those who do not shows the effect of training on respiratory system. In addition to this, the difference of respiratory functions between branches shows that the sport branch influences the respiratory capacity.

The Effects of Acute Aerobic and Anaerobic Exercise on Blood Parameters

Abstract The study attempts to investigate the effect of acute aerobic and anaerobic exercise on blood parameters and to determine whether blood parameters change between aerobic and anaerobic exercise. To achieve the objectives of this study, 25 male athletes participated in the research. Aerobic (Shuttle run test) and anaerobic (Running aerobic) Sprint test (RAST) exercise test were applied to the test subjects with a one-week interval. Before the exercise (resting), 1 minute and 60 minutes after both exercises’ protocol, subjects’ blood samples were taken to determine the blood hematologic values. A rise in the values was observed in 1 minute after the exercise, but 60 minutes after the exercise it was observed that most of the hematologic parameters returned to the resting levels. It was found out that the effect of aerobic and anaerobic exercise on hematologic blood parameters was mostly similar.

Effects of Exercise on Levels of Depression

Abstract The aim of this study was to investigate the effect of exercise on depression levels. Beck Depression Inventory (BDI) was applied to a total of 605 subjects at different exercise levels. The BDI score of non-exercising group was 13.18, while the average score of those who exercise was found to be 8.93. Non-exercising group showed higher depressive symptoms than the exercising group. Gender had no significant difference on the levels of depression (p>.05). Non-exercising group was found to be more depressive than the exercising group (p<.01). It was observed that exercising resulted in a low level of depression and the level of depression was reduced as the exercise time was increased. It can be said that exercise had a positive effect on reducing depression. People should be motivated and encouraged for having the habit of regular exercise to improve the quality of life.

Comparison of Leadership Levels of Students at the Faculty of Sport Sciences and Other Faculties.

Leadership has a great significance in creating high performance and building team loyalty in sport. The purpose of this study is to compare the leadership levels of students studying at the Faculty of Sports Sciences and other faculties. In addition, leadership qualities were examined in terms of the variables of gender and place of stay. A total of 200 students studying at the Faculty of Sports Sciences (n=100; age 21.75±1.99 years) and other faculties (n=100 age; 20.49±1.52 years) participated in this study voluntarily. “Leadership Orientations Questionnaire” developed by Bolman and Deal [1] and adapted into Turkish by Dereli [2] to assess the leadership qualities of students was used as data collection tool. In the sub-dimensions of structural, transformational and charismatic leadership, the scores of faculty of sport sciences students were found to be significantly higher than the scores of the students in other faculties (p<0.01). The average scores of men were found to be higher than those of women in the sub-dimensions of transformational and charismatic leadership (p<0.05). It was concluded that the students studying at the Faculty of Sport Sciences had higher leadership qualities, with men having better leadership qualities.

Endurance performance according to Circadian Cycle

ABSTRACT The aim of this study was to investigate the endurance performance according to the Circadian Cycle. For this aim, 38 male students studying at the Faculty of Sports Sciences (age between 20-27 years) participated in the study. 20 m Shuttle Run test was used to measure the aerobic endurance of the performance. The measurements were taken in the morning (09:00am), afternoon (2:00pm) or evening (7:00pm) time. The test sessions were performed in a random order. For the statistical analysis Friedman Two Way Variance analyses and Wilcoxon Signed Rank test were used. The results of the study showed that the number of shuttles were found to be higher in the afternoon than in the morning time (p<0.0167). Although there is no statistically significant difference, the number of shuttles were found more in the afternoon than the number of shuttles in the evening. As a conclusion, the best aerobic performance was performed in the afternoon. Due to the presence of such a difference, the measurement times have been noted for future scientific studies.

Effects of Different Durations of Static Stretching on Flexibility, Jumping, Speed and Agility Performance

Abstract The aim of this paper was to research the effect of different static stretching time on some physical performance parameters. A total of 25 male volunteers who were actively involved in sports participated in the study. Flexibility, jumping, speed and agility performances of all the participants were measured after static stretching exercises on 5 different days and within different durations (no stretching, 10 seconds, 20 seconds, 30 seconds, 40 seconds). After static stretching performed in all durations, the value of flexibility was discovered to be higher than the state in which no stretching is performed (p<0.01). The jumping height after static stretching exercises performed in different durations is lower than the state in which no stretching is performed (p<0.01). 20 m running time and agility performance did not differ among the five trials. It was found that the length of static stretching duration increased in flexibility. Also, static stretching decreased vertical jumping performance and did not affect speed and agility.

Investigation of the Changes in Performance Measurements Based on Circadian Rhythm

Abstract The aim of this study was to investigate the circadian changes in some physical performance measurements. A total of 25 male volunteer university students (athletes) participated in the study. The athletes were subjected to simple and multiple reaction time, flexibility, vertical jump, dynamic and static balance tests on three different days and periods of time (09.00am, 14.00 pm and 19.00 pm). Oral body temperatures of the subjects were measured prior to each test. As a conclusion, when visual simple and multiple reaction time values were analyzed, the best results were at 09.00. For flexibility and jumping parameters, a gradual increase was seen between morning and evening with an increase in body temperature. In addition, it can be said that in studies conducted on athletes, measurement hours should be chosen carefully based on the parameters to be measured in order to get more correct and reliable results.
