Introduction: Lower back pain is a very common symptom in people of all ages. Various known and unknown pathologies and diseases can affect pain. Trunk muscle endurance is an important indicator of our back health and also an important predictor of lower back pain. Purpose: The purpose of the thesis was to determine a possible link between the endurance of the trunk muscles and the lower back pain in people with a sedentary workplace. Methods: We searched the PubMed electronic database for articles to be included in the review of professional and scientific literature. Keywords combination was ((trunk muscle endurance) OR (back muscle function) AND (sedentary) AND (back)). Results: In the literature review we included five studies that were no older than fifteen years. In four of five studies, which used different measuring tools to asses lower back pain was found that pain may worsen during prolonged sitting or standing. Participants with lower back pain had visibly lower trunk muscle endurance in two out of five studies (p < 0.05) than those without lower back pain. In two studies measuring the activity of the trunk muscles, they found a significantly lower (p < 0.05) activity of the trunk muscles during sitting compared to other standing positions. Discussion and conclusion: Based on the reviewed research, we can conclude that lower back pain is associated with lower endurance of the trunk muscles. All authors agree that pain can reduce physical activity, which in turn affects the lower capacity of the trunk muscles. For further research it would be necessary to carry out studies that would compare people with lower back pain and people without lower back pain. Equal representation of sexes would also be important and since lower back pain occurs in all age groups it would be necessary to divide the participants into age groups.
