The morphological appearance of rheumatoid synovitis and the serum MMP and TIMP-1 profile were correlated with the clinical activity of the disease, confirming the heterogeneity of RA. These associations also suggest that patients with different histological forms of RA might require different treatment regimens.

Purpose:The aim of the study was to determine the risks of activity by using Physical Activity Readiness Questionnaire (PAR-Q) and describe the PA profile using the short-version of the International Physical Activity Questionnaire (IPAQ-SF) among selected groups of sport science students. Material:The study covered 99 students -61 females aged 21.08 ± 1.43 and 38 males aged 21.24 ± 1.22 y. In order to asses and stratify the risk of PA the Polish short version of the IPAQ-SF was used. Results:The total level of physical activity of the male students was 3460.039±2502.207 MET-min/week and was higher than in the case of female students (3388,107±2204,290 MET-min/week). The dominant type physical activity of female and male students was intensive effort. Among 22 men and 39 women, risk factors for cardiac events, pulmonary and musculoskeletal injuries were reported. The relationship between PAR-Q results and the on the IPAQ-SF results was no statistically significant. Conclusions:This study demonstrates that students achieve the level of physical activity recommended by experts for the prevention of chronic diseases. This research allows sports science students to understand their own health issues through self-assessments of personal risk factors for cardiac events, pulmonary and musculoskeletal injury.
