The study course “Sport” at Riga Technical University (RTU) is a compulsory study course, which eliminates several obstacles that students face to be physically active. However, students often submit medical certificates with conclusions on sicknesses for the exemption from sports activities, although the promotion of physical activity of the population is an essential part of chronic disease treatment. In Latvia, problems related to medical certificates for the exemption from sports activities at school have been studied, but no research has been conducted on the reasons of exemptions from sports activities among students. The aim of the study: to evaluate the content of medical certificates for the exemption from “Sport” and the information provided by the doctor to the student and sports specialist on the necessary load frequency, duration and intensity of physical activity in the cases of most common diseases, as well as the attitude of students with irregular attendance of “Sport” towards sports activities at school. Methods: scientific information source analysis, document analysis (medical certificates), surveying, mathematical statistics. The study lasted for 5 years and involved 1249 students (730 men, 519 women, age 19.2±0.7). Results and conclusions: 50% of students have submitted medical certificates to a sports specialist with conclusions on sickness for exemption from “Sport”. In 34.8% of the cases the medicalcertificates did not include a diagnosis. The content of medical certificates is inconsistent, it does not provide the student and sports specialist with information on the necessary load frequency, duration and intensity of physical activity in the cases of most common diseases. Key words: medical certificates for the exemption from study course “Sport”, students’ attitude towards sports activities
