The physical activity attitude scale for secondary school students developed by Yildizer et al., (2019) was used (PAAS). PAAS consists of 5 sub-dimensions and 25 items. The necessary permissions were obtained for the scale method used in this study, with the decision of the Scientific Research and Publication Ethics Committee of Mardin Artuklu University, dated 08.06.2022 and numbered 2022/6-4. The sample group of the research consisted of 305 students, and the data obtained were analyzed with the SPSS 25.0 software. Independent sample T Test and One-Way ANOVA tests were used in the analysis of the data obtained from the participants. In the study, it was determined that the physical activity levels of female students were higher than male students. In the analyses performed in the research, a difference was found in the grade level of the secondary school students, and there was a decrease in the level of physical activity as the grade level increased. Also, "Pearson correlation analysis" was conducted in order to determine the level and direction of the relationship between dependent variables. In the correlation analysis, it was seen that the strongest relationship was between "PAAS" and the love sub-dimension (r= 0.807; p<0.05). As a result of the research, it was seen that the jobs of the mothers and fathers of the students, the number of siblings of the students, and the place of residence of the students did not lead to a difference in their attitudes towards physical activity.

With the effect of facilitating factors such as developing technology, variety of transportation vehicles, today's people act much less than in the past, leading to the problem we call "sedentary" life. Since the general rhythm of daily life in the past consisted of functions such as walking, climbing, bending over, crouching, and carrying loads, our entire movement system is naturally full of adaptations to such a lifestyle. Technology has separated physical activity from most occupations in our industrialized society. For the completely sedentary professional, activities consisting of only commuting have been the only source of exercise. In this way of life, the quality of life of people is negatively affected. As in developed countries, the interest in physical activity is increasing in our country. The biggest indicator of our body's adaptation to movement is seen in childhood. Children are generally very active, constantly under the influence of the motives of play, movement, and displacement (Canan, 2020). Physical activities are the activities that result from the energy consumption of the individual's continuous movements with the help of muscles and joints, resulting in increased heart and respiratory rate and varying levels of fatigue. For this reason, work activities in daily life (climbing stairs instead of elevators, walking to work, etc.) are also included in the category of physical activities (Guler and Agaoglu, 2021). Physical activity is the energy consumption resulting from any movement of the body made with skeletal muscles (Oze, 2015). Physical activities include various exercises, sports branches, games, dances, and daily activities that include bodily movements such as swimming, walking, running, jumping, cycling, head-neck movements, and arm-leg movements (Karaca et al., 2000). In today's society, it is emphasized that it is very important to be interested in physical activity in order to increase the life satisfaction of people and to be healthy. Physical activity emerges as a very important issue in the process of ensuring the normal growth and development of children (Demir and Filiz, 2004). Physical activity has psychological, physiological, and affective impacts that will affect the child's health in adulthood and childhood. Approximately 50% of obese children at the age of six and over may become obese in later years, and if a child is
