ENThe aim of the paper is to examine the characteristics of PA expression of the girls who do not do sports on weekdays in different seasons. The research sample included 24 adolescents – 8th formers who did not do sports. In the experimental group (hereinafter: Group E), the girls’ PA was increased by implementing an educational PA programme developed by the authors. The programme was implemented through different forms acceptable to the girls. The girls of the control group (hereinafter: Group C) did not participate in the events of the educational PA programme. The girls of both E and C groups participated in the classes of physical education. The sessions of the educational PA programme took place every Thursday, therefore, in the comparison of the PA averages of the Group E and C girls, physical activity on Thursdays was not taken into account. In our research, a PA tracking device–sensor Beurer AS 50 that records the number of steps was used. The studies of the girls’ PA were carried out in different seasons: autumn, winter, spring, and summer. The PA in Groups E and C was tested 4 times, each time for a fortnight: Test 1 in autumn (October 2012), Test 2 in winter (January 2013), Test 3 in spring (April 2013), and Test 4 in summer (June 2013). To avoid inexactitudes, other research methods were also applied: the respondents kept diaries, and the researcher monitored the process. To calculate the research data, SPSS for Windows 14 software was used: the arithmetic mean (X ) of the research outcomes, the arithmetic mean error (SX), and Student‘s t-test(t) were calculated. As established during Test 1, the girls of Group C were more physically active than the girls of Group E on Mondays, Tuesdays, Wednesdays, and Fridays (556 to 10,658 steps per day). However, on Thursdays, when PA educational sessions for group E took place, the PA in that group of 8th formers was better than in C group (p=0,013).In winter, the greatest PA (over 14,000 steps) was recorded in Group E on Thursdays. However, on other working days (Mondays, Tuesdays, and Wednesdays), no statistically significant differences between the groups were established. The lowest PA rate was recorded in Group C on Wednesday: about 10,000 steps per day on average. In spring, statistically significant differences were established between Groups E and C on all the working days of the week (p=from 0,000 to 0,025). The greatest PA of the Group E girls was observed on Thursdays and amounted to almost 20,000 steps per day. The 8th formers of Group E were much more active in spring than in autumn and summer, and the PA of the respondents of Group C (Test 3) increased insignificantly (by 794 steps per day) compared to their PA in winter. In summer, an evident increase in the PA of the girls of Group E was observed. The comparison of the outcomes of Groups E and C on working days resulted in significant differences on a daily basis, Mondays to Fridays. The greatest PA in Group E remained on Thursdays (over 17,000 steps per day), when the educational PA sessions took place. As witnessed by the analysis of the general PA amount on working days, the girls of Group E were most physically passive on Wednesdays. The outcome may have been affected by a tense timetable and the absence of a physical education class on that day. As established, the total PA of the girls in both groups during Tests 1 to 4 complied with the WHO recommendations (2010). However, the PA of the girls of Group E tended to increase and at the end of the academic year exceeded the outcome of the girls of C group by over 4,000 steps. [From the publication]
