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.

The analysis of existing information on physical activity and fitness as elements of health and well-being reveals that they are achieved particularly effectively in contact with nature. Physical education lessons outdoors, as a form of healthy training, have been performed in numerous countries for years, providing a response to the traditional indoor model of this kind of education. The purpose of this paper is to clarify the relationship between the participation of students in outdoor and indoor lesson activities and the change in their physical fitness. 220 students participated in an experimental study. The experimental group, which did exercise usually in open spaces, included 49 boys and 54 girls. The control group, which exercised inside school, consisted of 63 boys and 54 girls. The study period lasted two years and involved the fifth and sixth form of primary school. Experimental group subjects were 11.26 years old (±0.32) during the initial test, and the control group individuals were 11.28 years (±0.32). During the final test, the average ages of experimental group subjects was 12.96 years (±0.32), and 12.98 years (±0.32) in the control group. The International Physical Activity Test was applied in the study. The differences between the levels of particular components of physical fitness were not statistically significant during the initial measurement (p-values ranged from p = 0.340 to p = 0.884). After two years of outdoor physical education lessons, there was revealed a considerable increase in the speed, jumping ability, and aerobic endurance of the students. Statistically significant differences were observed in these three tests, including running speed (p = 0.001), legs power (p = 0.001), and endurance (p = 0.000). The findings encourage one to continue pedagogical experiments regarding physical activity in outdoor natural environments.

Objectives. The aim of the study is to determine the level and to compare the physical activity of students of the Medical University (MU) in Lublin and the University of Technology (BUT) in Bialystok, Poland, and the University of Beira Interior (UBI) in Covilhã, Portugal. Materials and method. A group of 823 people were examined: 108 students of the Medical University of Lublin, 118 students of Bialystok University of Technology, and 597 students of the University of Beira Interior in Covilhã. The study examined the level of student activity using the IPAQ questionnaire. Results. With reference to people (both women and men) studying at the MU in Lublin and at UBI in Portugal, the activity level was high, 60.2% and 51.8% respectively. In the group of BUT students sufficient activity prevailed-30.5% of the respondents. Insufficient activity level was characterized by 2.8% of MU students, 23.7% of BUT students and 12.7% of surveyed Portuguese students. Considering the gender of respondents, statistically significant differences in activity levels among Portuguese students were observed. A sufficient level of physical activity was characterized by a higher percentage of men than women, 37.5% and 33.8%, respectively. Conclusions. Students of the Medical University (MU), as well as Portuguese students, were characterized by a high level of physical activity, while students of the Bialystok University of Technology (BUT) had an adequate level of physical activity. Among women studying at MU, BUT and UBI in Portugal, the highest average energy expenditure values were related to walking effort. Among both women and men studying at MU, BUT and at UBI in Portugal, the lowest average values of energy consumption were for moderate activity. Students from MU spent less time sitting during one working day than BUT andUBI Portuguese students.

Introduction and objective. The WHO term 'physical activity' refers to all body movements produced by skeletal muscles which require energy expenditure. The ways to be active include daily activities, exertion in the performance of work, or active recreation. The objective of the study is to compare physical activity of the students of
