Introduction:
The study of health-related quality of life is an indication of the tendencies of modern medical-social sciences on preventive activities related to health promotion.. Such studies supplement objective health indicators of a medical character with subjective feelings of the subjects. Most of the research results presented in publications in this field concern mainly patients suffering from different diseases. In the context of promoting healthy behaviors, it is particularly important to study the quality of life of healthy people involved in physical activity.

Material and methods:
75 adult people were involved in the study (women = 24; men = 51). They were members of associations promoting physical activity in the area of Zaglebie Dabrowskie (Poland). The Short Form Health Survey (SF-36v2) was used to assess health-related quality of life.

Results:
The physical aspect of quality of life (70.0 ± 5.0 points) was less favourably appraised than the psychological aspect (87.0 ± 14.9 points). A statistically significant difference between women (61.0 ± 4.6 points) and men (64.0 ± 3.3 points) was observed on the subscale: role limitation – physical problems. The average results of the surveyed people’s health-related quality of life were higher than the mean general population results.

Conclusions:
People involved in associations promoting physical activity and a healthy lifestyle attain higher average results in health-related quality of life than the norms of the general population. The high assessment of mental health maybe connected with the positive relationship between physical activity and well-being. It may also be suggested that people involved in associations promoting a healthy lifestyle establish positive relationships with each other, which may favor a high assessment of social functioning.
