OBJECTIVES: Low energy balance is the consequence of decrease physical activity (PA), sedentary lifestyle, and inappropriate dietary habits in modern societies, while the most important indicator of energy transmission is PA. Several research point out the gender-related differences in PA where data on women are worse: they do sports less and choose less physical activity in their free-time than men. The aim of our research was to map the Hungarian adult’s vigorous physical activity examining gender differences. METHODS: Data were collected in Summer 2014. The representative (by age & gender) sample consisted of 1059 adults. The research was carried out in two Hungarian counties, Baranya and Zala. We developed a tablet-based survey to examine PA. Using the IPAQ long questionnaire, we examined nutrition habits by the Food Frequency Questionnaire; and gathered anthropometric data with body composition monitors. Data analysis was carried out by SPSS 22.0 for Windows. RESULTS: The sample size of adult participants was 1059 (female(F)=53.1%, male(M)=46.9%), their mean age was 48±17.54 years. The self-rated health index of the low PA group of the adults is significantly lower than medium of high PA groups, especially for women (p=0,024).  We found significant difference between the vigorous physical activity (VPA) carried out by men and women as on average men carry out 37.73 minutes more VPA compared to women (mean_F=77.97, mean_M=40.24 min/week, p<0.001). According to the age groups the VPA level of women after the age of 40 showed stability on a lower level while the reduction of VPA of men is continuous until the age of 60 when gender gap of VPA disappears (p<0.001). CONCLUSIONS: Regarding gender differences, women were less active than men in PA, carrying out significantly less vigorous PA. The results of the observational research confirmed the need for a well-aimed intervention to emphasize PA among women.
