Purpose: The aim of the study is to assess the determinants, level and type of physical activity undertaken by adults in relation to the recommendations on physical activity. Basic procedures: The study group consisted of 225 people aged 18-68 years. Selection of the sample was stratified. As the research technique the Polish version of the International Physical Activity Questionnaire (IPAQ) was used, short version. For statistical analysis, Statistica 10 PL was used. In all analyses considered relevant were those effects, for which the level of test probability p was lower than the assumed relevance level a = 0.05 (p <0.05). Main findings: The study shows that women practice less intensively and for shorter time than men. As in the case of gender and physical activity, there is a significant difference (p=0.0170) as far as the type of education, and frequency of undertaking intense and moderate physical activity are concerned. People with a secondary education undertake both intense and moderate physical activity more often and for longer periods of time, in comparison to people with higher and primary education. The research shows that physical activity levels do not increase with the education level. There is not a statistically significant difference between profession and the degree of intensity of exercise. Conclusions: There is a significant correlation between gender and education, and performed physical activity. Age and profession are not factors determining the level of physical activity.
