It is well known that punching force is highly important to boxers for winning and one of the key components of amateur boxing. Boxing needs also get blocking position, after throwing a punch to not receive a punch.The aim of the study was to determine the dominant internal-external shoulder muscles and dominant extension-flexion leg muscles strength of the elite boxers at 60° and 180° sec-1. In the study, 10 male elite boxers 22.10 ± 1.37 years, height 174.60 ± 6.41 cm and 72.60 ± 10.74 kg participated in the study. The isokinetic knee and shoulder strength tests were performed with an isokinetic dynamometer (Cybex, Humac Norm 2004) in the kinanthropometry laboratory of Selcuk University. Statistical analysis of the data was performed using SPSS 22 package program. Descriptive data of the participants were given as mean, minimum, maximum and standard deviation. it was determined that the peak dominant leg strength of elite boxers were found for extension 224.900 nM (60 °/s) and 135.70 nM (180 °/s ). The peak dominant leg strength of elite boxers found for flexion 120.50 nM and 72.30 nM at 60 °/s and 180 °/s respectively. Elite boxers’ leg strength was similar to literatur. As a result of the study, it can be said that the internal muscle group of boxers produce more power than external muscle group. It can be concluded that the boxers have better punching strength than defense.

ABSTRACT Aim: The aim of this study is to investigate the communication skills and happiness levels of athletes engaged in different sports branches. Material and Method: In the research, 240 amateur and professional athletes, who are active in the province of Kirsehir and volunteer, participated in the study. The questionnaire, which was formed in order to determine the characteristics of the athletes, "Communication Skills Assessment Scale (CSAS)" developed by Korkut (1996) and Happiness Scale developed by Demirci (2017) were used in data collection. Findings: When the happiness levels of the participants were examined according to gender, it was observed that the happiness levels of women were statistically significant compared to men (p>0.05), but there was no difference between communication skills according to gender (p>0.05). It was observed that professional athletes had higher levels of communication skills and happiness than amateur athletes (p <0.05). In the study, it was seen that the communication and happiness levels of the athletes who have 10 years or more sports experience are higher than the athletes who have less experience (p <0.05). It was seen that the happiness level of the participants who had 3 or more siblings were higher than the participants with 1-2 siblings (p <0.05). Result: As a result of the research, it was seen that female athletes' happiness levels were higher than those of male athletes, but there was no difference in communication skills of male and female participants. Professional athletes have higher communication skills and happiness levels than amateur athletes and the communication skills and happiness levels of the athletes who have 10 years or more sports experience are higher than those who have less experience. The happiness level of the participants who had 3 or more siblings were higher than the participants with 1-2 siblings.

The purpose of this study was to examine the acute effect of different stretching protocols on flexibility, Yo-Yo IR-1 and repeated sprint performance. The sample group of this study consists of 15 male (age: 21.80±1.37 years, stature: 1.77±.032 cm, body mass: 69.09±6.65 kg, body mass index (BMI) 21.94±2.01 (kg/m 2 ), body fat ratio (BFR) 10.87±3.98 (%)) who were doing regular exercise at least 3 years. This group performed 5 different stretching protocols on non-consecutive days. Stretching protocols were determined as follows: light jogging for only 5 minutes (NS), light jogging and static strectching (SS), light jogging and dynamic stretching (DS), light jogging and static + dynamic stretching (SDS), light jogging and dynamic + static stretching (DSS). Altough participants did not have a statistically significant effect on flexibility performance (p> 0.05), the best flexibility value was SS. Repeated sprint performance (best) values of different stretching protocols did not have statistically significant effect on repeated sprint performance (moderate, worst, decline, post fatigue index) values (p> 0.05). Repeated sprint performance was found to have a statistically significant effect on Borg values and HR mean values (p <0.05). It was found that Yo-Yo IR-1 has a statistically significant effect on BORG values, Yo-Yo IR-1 performance HR (pre) values, Yo-Yo IR-1 performance HR (middle) values and Yo-Yo IR-1 performance lactate values (p<0.05). According to the findings obtained as a result of the research; it has been observed that different stretching protocols have different effects in terms of repeated sprint, flexibility and Yo-Yo IR-1 performance parameters. Overall, these results suggest that flexibility performance may be improve after static stretching exercise.

ABSTRACT The aim of our study is to investigate the dietary habits of amateur and professional football players and their differences. A hundred football players actively playing football during the 2013-2014 football season in 2nd League A Category, 2nd League B Category, 3rd League, 1st Amateur and 2nd Amateur Leagues participated in our study. A questionnaire that consists of 17 personal information and nutritional habits questions was developed based on the literature and was filled out by the players to determine their nutritional habits. There were statistically significant differences between the groups at p<0.01 level across their education level on nutrition issues, number of meals, alcohol and cigarette use, daily fluid intake, pre-game fluid intake, pre-game foods consumed, liquids and food consumed outside of three regular meals, late-time meals, regular supplementary products and last food before games. There were statistically significant differences between the groups at p<0.05 level across information resource on nutrition issues, skipped meals, fluid intake during training, late time meals, attention to expiration dates while shopping. In conclusion, consistent with previous studies in the literature it is found that amateur and professional football players don’t have good nutrition information and habits. Clubs, coaches and athletes looking for success on a national and international level should consult and collaborate with a nutritionist. We believe that it will be very useful to train athletes and coaches, with seminars, courses, panels, etc. and to have an expert dietitian in sports clubs, and to emphasize the importance of this issue in written and visual media.

ABSTRACT Studies in sport genetics have increased nowadays and the identification of genotype and allelic distributions of candidate genes in different athletes has provided important information to sports scientists. One of the candidate genes studied in sports genetics is the hypoxia-inducible factor 1-alpha (HIF1A) gene, which is associated with the endurance phenotype. In our study, we aimed to determine the genotypic and allelic distribution of HIF1A rs11549465 polymorphism in Turkish Elite Ski Runners. 34 (23 male, 11 female) athletes were included in the study, and 1 cc of blood samples taken for routine analysis after the approval of the ethics committee was used for DNA isolation. The commercial kit was used for DNA isolation and genotyping was performed by Real-time PCR method. The number and percentage of CC, CT and TT genotypes of the HIF1A rs11549465 polymorphism were 24 (72.72%), 8 (24.24%) and 1 (3.03), respectively. In male skiers CC, CT and TT genotype numbers and percentages were determined as 17 (55.51%), 4 (12.12%) and 1 (3.03%) respectively. In female, CC and TT genotypes were determined as 7 (21.21%) and 4 (12.12%). We detected no TT genotype in female athletes. When we look at allel numbers, C allele was determined as 56 (84.84%) and T allele was determined as 10 (15.15%). This is the first study on HIF1A rs11549465 polymorphism on Turkish elite ski runners. The higher prevalence of CC genotype and C allele in the athlete group is similar to the previous studies on different groups of athletes. We believe that this study will be an important reference for further studies.

Abstract It is known that anabolic steroids are used by athletes to increase their performance and cause many health problems. This study aims to analyze the effects of methenolone enanthate supplement with exercise on rats’ bones. The study was conducted with 28 28-day-old Wistar male rats obtained from the Chair of the Experimental Medicine Researc h and Application Center of Selc uk University. The rats were allocated into four groups: C (control, n:6), E (exercise, n:7), M (methenolone enanthate, n:7) and ME (methenolone enanthate+exercise, n:8). The required doses were arranged weekly depending on the rats’ live weight for the groups given methenolone enanthate. The rats’ front and back extremity bones were dissected, and the humerus and femur bones were dried. Each bone’s length, corpus thickness, cortex thickness and medullary diameter points were determined. The results were presented as mean±SD. ANOVA and Duncan's test were used for inter-group comparison of the data. The threshold for statistical significance was p 0.05). It was concluded based on the study results that methenolone enanthate supplement causes early epiphyseal closure in rats’ femur and humerus bones and stops the increase in these bones’ length. In addition, exercise was found not to reduce this negative effect of methenolone enanthate. Although the prohibited substances classified as anabolics are considered to increase performance by some athletes, these substances are not recommended for use due to their negative effects on athletes’ health.

ABSTRACT The aim of this study was to compare the health perception and life satisfaction levels of the individuals doing recreational sports according to various demographic variables and to determine the relationship. This study was conducted on the basis of survey model; Individuals attending recreational fitness centers in Konya participated on a voluntary basis. “Health Perception Scale” which was developed by Diamond et al. (2007) and adapted to Turkish by Kadioglu and Yildiz; and “Life Satisfaction Scale” which was developed by Diener et al. and adapted to Turkish by Koker (1991) were used. SPSS 20 package program was used to analyze the data. In the evaluation of the data, complementary statistical methods like standard deviation (sd) frequency (f) percentage (%) average (M) and since normal distribution conditions were not met Kruskal Wallis Test and Mann-Whitney U test, which are non-parametric tests, were used. Spearman Correlation coefficient test was used to reveal the relationship between them. Results were evaluated at 0.05 significance level. As a result of the study, when the health perception scale and life satisfaction scale were compared according to the variables of gender, age and educational status, statistically significant differences were found and it was found that the relationship between life satisfaction and health perception scale had low positive correlation levels with each other. In this context, health perception and life satisfaction can be evaluated as factors affecting each other.

ABSTRACT The aim of this study was to examine the effects of 8 weeks beta-hydroxy-beta-methylbutyrate (HMB) supplementation with resistance training on some components of physical fitness and body composition in young males. Twenty healthy young men volunteered to participate for the study and divided into two groups and performed 8-week resistance training while supplementing with either HMB or placebo (3 g per day). The subjects were evaluated for 1 repetition maximum (1RM) bench press and leg press, vertical jump (VJ), anaerobic power (RAST) prior to and after training intervention. In addition, body composition variables such as percent body fat, and BMI were assessed per and post training period. Both the groups showed significant increases in 1RM bench press and leg press, VJ, and anaerobic power (RAST), and also the HMB supplementation group showed greater gains compared with the placebo. In addition, percent body fat decreased significantly in HMB and placebo groups. BMI enhancements were greater for the HMB supplementation group indicated gains in body weight. The results indicated that resistance training improved physical performance and HMB supplementation induced greater gains and therefore it could be recommend to coaches and athletes who use this supplementation to greater gains in physical fitness variables.

ABSTRACT The aim of the study is to compare the agility, vertical jump and velocity parameters in children between 6-12 years of age. One hundred thirty-six children (61 girls, 74 boys) participated as volunteers. The t-test was applied to the participants as a measure of agility test. Vertical jump and 20 meters speed test were applied. Statistics were performed using by SPSS package program. The data were evaluated by the Shapiro-Wilk test for normal distribution. Mann Whitney U test was used for intergroup comparisons. Accordingly, there is a significant difference in favor of males in the vertical jump in the 10-year age group (p<0.05). There is a significant difference between males and females in the 9 and 10 age groups in favor of males in vertical jump and speed (p<0.05). There was no statistically significant difference in the agility test, but the data showed that men performed better.
