Developing the awareness of one's level of physical activity is an important prerequisite to change one's lifestyle into a more physically active and healthy style of living. The aim of the study is to verify the efficacy of pedometers in educational environments and to specify the differences between physical activity in boys and girls aged 17. Twenty seven boys and thirty seven girls from randomly selected classes in two high schools in Katowice, Poland participated in the study. Students wore Yamax SW-700 pedometers for three weeks, continuously recorded data from the pedometers, and used the motivational feedback booklets. The three-week intervention using pedometers was complemented with the IPAQ questionnaire to assess their physical activity during the last seven days.For statistical analysis, we used basic statistical characteristics, Mann-Whitney test, repeated ANOVA, "effect size" coefficient ω2 (Tolson, 1980), and other partial analysis programs in Statistica 6 and SPSS 15.Both boys and girls were less physically active on weekend days during the analyzed period. The use of pedometers did not decrease the difference between physical activity on school days and weekend days. No significant differences were found in the average number of steps per day between boys and girls, as well as no significant differences were identified in the interaction of gender vs. school and weekend days.Additional study is necessary to confirm whether the use of pedometers in physical education classes can help decrease the differences in physical activity between boys and girls.

Intoduction: The aim of the thesis was to research the influence of level and frequency of the taken activity on health related somatic features of middle-aged and elderly women. Materials and methods: The research was carried out among 80 women aged 46-81, who were auditors of the Universities of the Third Age in Katowice and Chorzów. The analysis of body composition has been made with the method of bioelectrical impedance analysis, using the Inbody 720 device. As health related somatic features, the following parameters have been found: (BMI- kg/m2) - body mass index, (BFMI- kg/m2) - body fat mass index, (FFMI- kg/m2) - fat-free mass index, (WHR) - waist-hip ratio and (VFA-cm2) visceral fat area. The level and intensity of physical activity have been measured with the use ActiGraph GT1M device. The differences between average variables analyzed have been compared with the use of an analysis of variance (ANOVA) and the level of p <0,05 have been taken as statistically significant. Results: The research show that 60% of women achieved the recommended limit of 10000 steps a day, but the results of the most active group which performed on the average above 12500 steps were the closest to the correct body composition indexes (BFMI - 8,71 kg/m2, VFA - 116,94 cm2). The differences between average variables of BMI, BMFI, VFA, WHR of women who achieved and did not achieve the minimum of 30 minutes of physical activity with the intensity of 3-6 MET at least 5 times a week were not statistically significant and the results in both groups exceeded the scope of norms. Physical activity defined by the amount of days a week (≤2, 3-4, ≥5), when the women exceeded 10000 steps a day has statistically significantly differentiated all the variables describing the level of body adiposity and the results approach to the scope of norms. Conclusions: The level of the physical activity defined by the number of steps performed (<7500, 7500-9999, 10000-12500, >12500), statistically significantly differentiates all health related somatic features (BMI, BFMI, FFMI, VFA, WHR) of the women. Frequency of the physical activity has statistically significantly differentiated all the variables describing the level of body adiposity (BMI, BFMI, VFA, WHR). Monitoring the amount of the steps performed with the use of motion sensors can be an effective tool of control and evaluation of physical activity.

Available evidence suggests that interest and participation, especially in vigorous physical activity, declines with age during adolescence. This negative attitude toward vigorous physical activity is especially prevalent among female adolescents. This study investigates how increasing intensity levels of aerobic dance, a popular physical education choice of female students, influence the attitude of female high school students toward the activity.A total of 313 female high school students from eight schools (age 16.32±1.74; weight-kg 53.73±7.58; height-cm 164.37±5.61; BMI-kg/m2 19.87±2.55) participated in the study. Student intensity levels during the aerobic dance lesson were monitored using heart rate monitors, accelerometers and pedometers, and the influence of intensity level on attitude toward aerobic dance was measured by use of a standardized questionnaire. The results clearly show that increasing intensity levels did not diminish the positive attitude of female students toward aerobic dance.
