In this study, it was aimed to investigate the relationship between 8-week-old zumba and step-aerobic exercises with serum leptin and serum ghrelin. Semi-experimental method used in qualitative and quantitative research was used in the study. The experimental group consisted of 26 women who voluntarily participated in the study, with an average age of 41.40 +/- 9.90 years, who did not smoke or drink alcohol, do not exercise regularly, and lead a sedentary life. The experiment group was performed zumba and step-aerobic exercises with various choreographies for 3 weeks, 2 hours each, for 8 weeks. Blood samples were taken to determine the levels of hormone levels of the serum leptin and serum ghrelin three times before the exercise program, the 4th week of the exercise program and the end of the exercise program. Blood samples were taken in the morning hours after 8-10 hours of fasting. The data obtained as a result of the measurements were transferred to the computer environment. SPSS 20 package program was used in the analysis of these data. As a result of the analysis on the normal distribution of data, it was revealed that it showed a normal distribution. In the analysis of these data, Single Factor Variance Analysis (ANOVA) was used. Significance levels were evaluated according to p <0.05. As a result of the statistical analysis of the findings obtained in the research; The participants in the study were found to be statistically insignificant (p> 0.05) although there was a decrease in leptin and ghrelin levels. As a result, regular zumba and stepa-erobic exercises were found to cause a decrease in serum leptin and ghrelin levels in sedentary women, although not statistically significant.

In this study, it was aimed to examine the effect of protein and carbohydrate consumption on repetitive maximal strength and body composition during the 10-week strength training. The mean age and height of the groups are as follows; experimental group CAR: (n=10) 20.04 +/- 1.38 years, 173.44 +/- 4.62 cm, PR (n=10) 21.29 +/- 2.44 years, 177.24 +/- 4.22 cm and placebo group; PLA (n=10) 20.14 +/- 2.19 years, 174.15 +/- 5.12 cm in total and 30 inactive male individuals participated in the evaluation. The research was conducted as a single blind study. Scitec Isolate Whey Protein and Hardline Carbopure supplementation was given to the experimental groups under the researcher supervision for 10 weeks in appropriate for daily use type and dose. 0.75 g/kg protein was given to the PR group two hours before the training, 0.75 g/kg protein was given immediately after the training and totally 1.5 g/kg 500ml water and protein supplement was given on the days of training. In carbohydrate supplementation, carbohydrate supplements were applied as 3.0 g/kg two hours before the training and 3.0 g/kg immediately after the training, and a total of 6 g/kg 500m1 water on the days of training. In the research, synthetic colorant, which does not increase blood sugar, was given to the PLA group with 500m1 water in equal amounts to the given supplement. As a result; while the use of carbohydrate and protein supplements in the 10-week strength training performed 4 days a week provided positive improvements on body composition and 1MT, especially the use of protein provided more positive developments on fat percentage and lean body mass.

This is the first study to determine the effects of strenght exercises on irisin and correlation of bady composition and irisin. The purpose of this study was to determine the effects on body composition and irisin of static strength exercises with Tera-Bant (R) in elite boxers. 9 volunteered elite male boxers participate in the study who are nonsmokers and did not use any nutritional supplements. Boxers were instructed to perform strength exercises with Thera-Band for 3 days a week for 8 weeks. Blood samples were taken before exercises (resting), after the first exercise (acute) and after 8 weeks following the last exercise (chronic), and measurement of body fats were made at the same time. Irisin levels of blood were examined. Statistical analyses were carried out using the SPSS 22 for Windows. The data were found to not be distributed normally. Thus, Friedman, Wilcoxon, Mann-Whitney U and Speraman's correlations tests were used. The results were evaluated using an alpha level of .05. Body Fat Percentage (BFP) and Fat Mass (FM) levels of athletes increased, Lean Mass (LM) decreased relatively both after a single session and after 8 weeks. While irisin concentration increased after a single session, (correlation in pre exercise and after a single exercise. Static strength exercise is effective on body fat both acutely and chronically, and effective on irisin only acute. Farther, the body fat and irisin are related to the negative.

The aim of this study is to determine the speech anxiety levels of physical education and sports department students and to examine them in terms of different variables. The research was carried out with 202 students (66 female and 136 male) studying in different departments of Erzurum Ataturk University Faculty of Sports Sciences in 2108/2019 academic year. The data related to the study were collected by Speech Anxiety Scale developed by Yaman and Sofu (2013) and the Demographic Information Form determined by the researchers. Frequency distribution was used to determine the students' demographic characteristics, Independent Samples T-test was used to examine the differentiation between two independent variables and speech anxiety and One-Way ANOVA analysis was used to examine the differentiation between more than two variables and speech anxiety. All these tests were analyzed in SPSS 21 package program and the significance level was accepted as p <0.05. As a result of the research, it was determined that there was no significant difference between the students' demographic characteristics, sporting activities and speech anxiety levels. Although there was no significant difference, it was also observed that the male students' total score of speech anxiety was lower than that of female students numerically. It was observed that, regarding the students' family structure variable, those who had a fragmented family, who had a monthly personal income level of over 1501 TL, who studied in the department of management, did sports activities and performed both sports as regards their sports activity type, had numerically a low level of speaking anxiety when compared to other variable groups. In the light of these results, it is suggested that students should be encouraged to participate in sports activities and to engage in different social activities in order to reduce their speech anxiety levels. Apart from this study, it is recommended to investigate using different variables and to determine the variables that may have a positive or negative effect on speech anxiety.

The aim of this study was to determine whether there is a relationship between strength, speed, flexibility, agility, and anaerobic power in elite athletes. In various sport branches 29 active male athletes participated in this study with an average age of 21.14 +/- 1.98 years who without any health problems. Back and leg strength were measured by dynamometer (Takei), speed was measured by 20 meters test, agility was measured by T test, flexibility was measured by sit and reach test, vertical jump sit-reach test by Jumpmeter (Takei) anaerobic power was calculated by the Lewis formula. The data were analyzed in SPSS 22.0 for Windows package program. Bivariate - Pearson Correlation test was used to determine the relationship between strength, speed, flexibility, agility, and anaerobic power. The results were interpreted as .05 significance level. We were found positive and significant relationships between the back and leg force, between anaerobic power and vertical jumping, between anaerobic power and back force, between anaerobic power and leg strength, and between flexibility and vertical jumping. And also, there was a negative and significant relationship between flexibility and agility, between speed and vertical jump, and between agility and vertical jump. In this study, it was concluded that strength, vertical jump and anaerobic power was related both each other and the other. For this reason, we recommend that the trainings cover all motoric characteristics.

The aim of this study is to determine whether there is a relationship between hand/arm and leg flexion and extension strengths of elite athletes as well as back and general leg strengths and reaction times. From various branches, 29 healthy elite male athletes between 18-25 years old participated in the study. Flexion and extension strengths in hand/arm and leg, back and general leg strengths were measured with Lafayette Manuel muscle test device, while back and general leg strengths were measured with TAKKEI (brand) dynamometer, and reaction times were measured with the device developed by Agirbas et. al. (2019). The relationship between the values of the athletes was examined with Bivarite - Pearson Corelattion test. The results were interpreted at the significance level of .05. Statistically, significant relationships were determined between right-hand extension strengths and right-hand visual reaction times of the athletes while sitting, between left-hand flexion strengths and left-hand auditory reaction times while sitting, and between general leg strengths and all reaction times. In the study, it was concluded that flexion and extension strengths do not affect reaction time but there is a negative-sided strong relationship between general leg strengths considered as the resultant Strengths and all the leg reaction times.
