摘要：The aim of the research was to determine, based on a systematic review of published studies that dealt with barriers to physical activity in adolescents, which are the most common barriers that stop adolescents from engaging in physical activity. Within the research original scientific studies are included, the ones that had male and female adolescents as a sample of respondents, studies related to the analysis of barriers that occur in adolescents, in which assessments were made on the basis of a questionnaire related to barriers. The research included studies from January 1, 2003 to July 2020. The final analysis, based on the set criteria, included 11 studies that were processed and presented. Most studies have shown that more internal barriers than external ones occur in girls comparing to boys, while external barriers are more common causes of not engaging in physical activity in boys. The three most common barriers among boys were: lack of company, lack of time and school obligations. Among girls, the most commonly reported barrier was "I'd rather do some other activities" and reporting a lack of time. The significance of this research is that it provides information on barriers in respondents who are adolescents, ie the reasons why their physical activity is reduced or they do not engage in physical activity at all.
