The aim of this study was to investigate the development of concepts, levels of physical fitness related to health and physical activity patterns provided by the Physical Education (PE) classes. The sample consisted of 40 students (24 boys, 16 girls) high school students. Physical fitness was measured by the sit and reach test, running in 9 minutes and abdominal strength in 1 minute, belonging to the battery of tests PROESP. The knowledge was determined by theoretical test. The physical activity score was estimated by the International Physical Activity Questionnaire (IPAQ). In 30 PE classes the teaching contents were related to the concepts of stretching and gym exercises: Interval fitness and running. There were significant changes in abdominal strength, flexibility and knowledge to both sexes and aerobic endurance for girls, indicating that classes, worked through teaching procedures aimed at health promotion can modify the concepts and health-related physical fitness of high school students.
