The purpose of this study is to identify the attitude of students of sport high schools and those of other high schools towards physical activities and their levels of satisfaction with life and to examine whether there are differences between these two student groups. In the study, 3 different scales were used on 368 students in total, who were studying in Sivas province in 2017-2018 Educational Year, found by convenience sampling method. The first scale is “the Personal Information Form”, which consists of 8 articles, for identifying the demographical characteristics of the participants; the second scale is “the Cognitive Behavioral Physical Activity Questionnaire (CBPA)”, which was developed by Schembre et al., (2015) and was adapted to Turkish by the validity and reliability study done by Eskiler et al., (2016), for identifying the participants’ attitudes towards physical activities. The third scale is “the Satisfaction with Life Scale”, which was developed by Diener et. al (2002) and prepared as 5-statement 5-point likert type, for identifying the participants’ levels of satisfaction with life. SPSS 25 package software was used in data analysis. The data were reflected as values of percentage, frequency, and average standard deviation. 180 sport high school students and 188 other high school students were participated in the study, when looked at the findings acquired. It was found that the attitude levels of sport high school students towards physical activities are higher than those of other high school students, and in parallel, it was seen that they have higher levels of satisfaction with life. As a result, it can be said that regular physical activity positively increases the individual’s satisfaction with life. Thus, regular physical activity is recommended.
