<b><i>Objective: </i></b>The aim of the present study is to examine the differences in fat and carbohydrate (CHO) oxidation during walking and running between normal-weight and overweight/obese young adult men. <b><i>Methods: </i></b>19 healthy, normal-weight (age = 21.9 ± 0.7 years, BMI = 22.6 ± 0.4 kg, n = 10) and overweight (age = 21.4 ± 0.6 years, BMI = 31.6 ± 1.1, n = 9) young men volunteered to participate in this study. Body composition was assessed by bioelectrical impedance. Maximal oxygen uptake and maximal fat oxidation rate were determined with indirect calorimetry by using an incremental exercise test on a motor-driven treadmill. The participants’ individual preferred transition speeds between walking and running were determined. Indirect calorimetry was used to calculate fat and CHO oxidation during the resting, walking and running tests.<b><i> Results: </i></b>Maximal fat oxidation rates during the graded exercise test were not significantly different between the groups. Changes in CHO and fat oxidation in the resting, walking and running tests were similar in the normal-weight and overweight groups. <b><i>Conclusion: </i></b>The study results suggest that with regard to changes in CHO and fat oxidation, normal-weight and overweight/obese individuals have similar responses to walking and running at preferred speeds, despite significant differences in oxygen uptake during activity and body composition.

The Relationship between Social Media Addiction and Depression: "A Survey among University Youth" Today, social media is widely common and increasingly popular medium among young people. If any of social media that enables people to display their personal interests on personal pages, communicate with each other through various applications, obtain information, make friendships, share photos and images with other people, and provide data to people about personal information, is used extremely and unconsciously, it can be addictive. There are many factors associated with social media addiction as a type of behavioral addiction. In this study, the relationship between social media addiction and depression is examined. A field survey method is used in the study and the data is obtained from 303 face to face interviews with some university students. As a result of the research, it is found that there is a positive correlation between social media dependence and depression. The ones who have severe depression symptoms; have higher social media addiction scores than those with normal and mild depression. Depression, duration and frequency of using social media are defined as the determinants of social media dependence.

Kodokan officially published the first refereeing rules in 1955 before the World Championship in 1956. Since then International Judo Federation (IJF) has implemented many changes such as contest area size, judo uniform colour, weight categories, classi-fication of penalties and scores, hantei (determination of the winner by referees at the end of the match with flag), golden score with limited time and golden score with unlimited time. [1][2][3] Especially during the last decade, refereeing rules have been changed a lot to
