Background and Study Aim. The aim of this study is to determine the effect of e-sports on physical activity level and body composition. Material and Methods.  The athletes who participated in the study were 19.92± 2.21 years of age, 1.73±0.04 m body height and 78.35±6.52 kg body weight. A total of 137 athletes participated in the study, including 27 from Turkey, 47 from South Korea and 63 from the United States (USA). The data was collected by e-mail from the sports clubs. The athletes who representing their country in international competitions involved in the study. The data obtained were evaluated in the SPSS program. Results.  According to the findings of the study, the body mass index (BMI) of e-sport athletes is 26.03±1.85, the number of physical activity steps is 6646±3400 and the daily e-sport hours are 9.34±1.12. The BMI was determined as USA 26.12, South Korea 26.02 and Turkey 25.84 respectively. The number of physical activity steps was identified as 5255 steps in the US, 7785 steps in South Korea and 7909 steps in Turkey. The daily e-sports hour is set at US 9.63 hours, Turkey 9.29 hours and South Korea 8.97 hours. In comparison of country-based athletes, there was a significant difference between physical activity level and daily e-sports hours at p<0.05. The value of BMI is not different. Although it is not statistically related to the physical activity level and BMI. There was no statistically significant relationship between daily e-sports hours and BMI and physical activity step counts. However, as the time of e-sports increases, BMI increases and the number of physical activity steps decreases. Conclusions.  As a result it is seen in the findings of the research that athletes dealing with e-sports are included in the fat group as a body composition and their daily physical activity steps are low. In addition, according to the results of the research, e-sports are thought to have negative effects on physical health. Thanks to the physical activity programs to be applied to these athletes, it is thought that their body composition and physical activity levels can be improved.

Background and Study Aim. The aim of this study is to determine the effect of functional movement screen and lower extremity training on hamstring/quadriceps (H/Q) ratio in football players. Material and Methods. 11 players from Sivas Belediyespor, affiliated to the Turkish Football Federation, participated in this study. The average age of the players involved in the study was 25.75±4.45, height averages 178.49±8.72 cm, and body weight averages 69.83±6.47 kg. Players who participated in the study had previously suffered a knee area injury. In addition to team training for 8 weeks, extra exercises to strengthen their hamstring and quadriceps muscles were conducted 3 times a week. Isokinetic force tests and Functional Movement Screen (FMS) tests were conducted in the study. Data obtained were evaluated in SPSS package 24 program. Results: There was a significant difference in the total score of FMS at the level of p<0.05. Deep squat 13.5%, hurdle step 10.49%, in line lunge 9%, shoulder mobility 3.44%, active straight 6.84%, trunk stability push up 6.84%, rotatuar stability 14.73% and FMS total score 17.24% showed improvement. There was a significant difference in the H/Q ratio between both the right knee and left knee pre-test and post-test at p<0.01 level. The right knee developed at a rate of 600 H/Q at a rate of 17.24% and the left knee developed at a rate of 600 H/Q. Conclusions: As a result, 8 weeks of extra lower extremity exercises can be said to increase the H/Q ratio of football players. It is also seen that the FMS score has increased. Thus, it is thought that the risk of football players having a sports injury again is reduced.

The aim of this study was to compare life quality of people living in İstanbul, Ankara and İzmir having higher population density to those living in cities having lower population density. 2060 people from İstanbul, Ankara and İzmir, 5892 people from other cities, totally 7952 people, were participated in the study. Turkish version of WHOQOL-BREF scale consisting 27 items, developed by World Health Organization with the participation of 15 collaboration centers was used to determine life quality of participants. WHOQOL-BREF scale includes four dimensions; physical, psychological, social relations, and environment SPSS 16.0 was used to analyzed collected data. Descriptive analyze was used to determine characteristics of participants, Independent t test was used to compare cities having different populations densities, crosstab and chi square tests were used to analyze items not included in scoring. Significant differences were found between people from cities having different population density in terms of physical and environmental field (p<0.05), and psychological field (p<0.01). No significant difference was found in terms of social field (p>0.05). Consequently, according to higher level of life quality scores of people living in high population density than those living low population densities in terms of physical, psychological, social and environmental field, it can be said that it is a positive reflection of life to life quality in cities having higher population density.

The purpose of this study is to analyze the level of life quality of students in terms of social, psychological, environmental and health areas. In order to collect data for the study, the Whoqol-bref short scale adapted to Turkish by Fidaner in 1999 was used. 5264 students volunteered to participate in the study. An online survey was created through Google drive. With the purpose of making the survey which was created in the online environment reach individuals by promoting it on social media and preventing them from taking the survey more than once, the survey was sent to individuals' mail addresses to be answered. The SPSS program was used in the evaluation of study data. When the physical area was analyzed as a result of the evaluations, a statistically significant difference was found in the p<0,001 level in terms of gender and p<0,01 level in terms of environmental area. A significant difference was not seen in the p>0,05 level in terms of gender between psychological and social areas. A positive relationship was observed between the perception of life quality and being content with health and physical, social, environmental and psychological areas. A negative significant relationship was observed between the level of difficulties experienced with people whom individuals feel close to in their lives and physical, social, psychological and environmental areas. As a result, the level of life quality of men was determined to be higher compared to women. In summary, it can be stated that physical, mental and social situations which might be effective in the lives of individuals influence individuals' lives.
