The conclusion of the study is that it is important to include at least the recommended amount of physical activity every day, i.e., an hour a day. The benefits of the physical activity are not stored which is why high school students should be guided to make physical activity as a part of their daily routine. Physical activity that promotes well-being and prevents school burnout is meaningful for the students and takes into account the total workload.
