Background: The aim of this study was to assess the relationship between the number of steps a day and biological (body fat, lean body mass, BMI and estimated VO2 max) and psychological (self-efficacy, enjoyment of PA and self-perception of body image) factors in 16-18-year-old girls. Material/Methods: The study included data from 60 girls, aged 16-18. Voluntary participants were selected from a public high school in Poland. Number of steps was measured with a pedometer Yamax Digi-Walker, model SW 701, during 7 days. Girls were classified into three groups: low active, slightly active and active (5,000-7,499; 7,500-9,999; ≥ 10,000 steps/day, respectively). The levels of psychological factors were determined by means of a questionnaire survey. Estimated VO2 max was assessed by a 1-mile walk test. The percentage of body fat and lean body mass was evaluated using Bodystat 1,500, bio-impedance method. Results: Analysis of variance showed no statistically significant differences in the biological and psychological variables among low active, slightly active and active girls. Conclusions: Girls in the study performed approximately from 5,000 to 12,500 steps a day. To explain better relationships between daily step counts and psychological and biological variables future research should additionally involve girls with less than 5,000 steps a day and more than 12,500 steps a day.

Study aim: the aim of this study was to assess the step counts of children and adolescents with different BMIs and to present the results in relation to the step count recommendation. Material and methods: the study included data from 175 girls, aged 12–18 (45 participants from primary school, 69 participants from junior high school and 61 participants from high school). Voluntary participants were recruited from public schools in Poland. Step counts were measured using pedometers (Yamax Digi-Walker SW 701) over seven consecutive days. Results: the recommended level of 12000 steps per day was achieved by only 14.9% of participants. The step counts performed by girls, especially at the primary school age, are currently insufficient. Participants’ achievement of the recommended step count level correlated with a lower BMI. Conclusions: few female children and adolescents are meeting daily step recommendations, which highlights the importance of school and community-based programmes designed to increase daily activity patterns.

Study aim: To assess the intensities of three types of physical education (PE) classes corresponding to the phases of the teaching/learning process: Type 1 - acquiring and developing skills, Type 2 - selecting and applying skills, tactics and compositional principles and Type 3 - evaluating and improving performance skills.Material and methods: A cohort of 350 schoolchildren, aged 13 years, from 3 selected urban schools in Poznań participated in the study. A total of 202 PE lessons was involved using heart rate (HR) monitors, one randomly selected subject per every class. Four intensity zones were assumed (<140, 140 - 159, 160 - 179, ≥180) and exercising time spent within each zone was measured.Results: Type 2 classes induced the most pronounced cardio-respiratory responses irrespectively of the kind of sport activities thus enhancing the cardio-respiratory fitness.Conclusions: Type 2 activities ought to be taken into consideration when designing PE curricula in order to avoid long runs of inadequate physiological stimuli.
