Abstract


The study aim is to examine the relationships between self-rated physical activity (PA), health related subjective and objective variables and psychological determinants derived from the Transtheoretical and Social Cognitive theories. The study sample includes 359 respondents aged 60 to 75 years. The short form of the International Physical Activity Questionnaire (IPAQ-SF) was used to assess the level of PA. As a subjective measure of health status it was used The Short Form Health Survey (SF-36v2). For objective health determinants were used the Heart Health consulting room cardiovascular risk factors assessment data. Multidimensional Outcome Exercise Expectation Scale (MOEES) data show the beliefs about the benefits of exercise. To detect the involvement in regular PA it was used the Exercise Stages of Change – a short form. The results show that 20.6% of respondents have “low” PA level, 30.4% are “moderate” and 49.0% are ”high” physically active. Nevertheless, only 19.7% exercise regularly more than 6 months and 49.9% do not even plan to engage regular activities in the next 6 months. MOEES data show that outcome expectations decrease with the age, the same as PA. These results influence a subjective health assessment, because more than half of respondents are rated below the General Population Norm of SF-36v2 survey. Moreover, poor adherence to exercise is closely related to higher cardiovascular illness risk (p<0.01).
