The paper aims to examine the interaction between lumber back pain and physical activity in the daily lives of young people who are 18-24 years old. The study included 200 subjects who did not use medication and who did not have any systemic chronic disease. IPAQ Short Form (International Physical Activity Questionnaire) and the Oswestry Low Back Pain Disability Questionnaire (ODQ) were used for data collection. The average age is 21,48. The surveys measured the impact of LBP in daily life and the Metabolic Equivalent (MET) values corresponding to the physical activity values alongside the frequency of daily activities. The medium age of the respondents was 21.48. 98 (49%) of them were male and 102 (5%) of them were female. We have determined a medium level positive correlation between the increase in physical activity and the negative impacts of the back pain and the correlation was 0,503. In other words, the results suggest that the activity level of the people with LBP did not decrease. Having said that, the results also suggest that as the MET level denoting the physical activity in daily life increases, the negative impact of the LBP in daily life also increases. LBP is a pain that limits activities and makes it difficult to stand up and even sitting down in some cases. 80% of the individuals having an active life have complaints with regard to LBP at some point in their lives.
