Study aim: To assess the physical activity of male and female adolescents from Poland living in a town (Czechowice-Dziedzice) and in a city (Katowice).Material and methods: The research involved 431 high school students aged 16-18 years (249 from Czechowice-Dziedzice and 182 from Katowice). Physical activity was measured by the short form of the International Physical Activity Questionnaire (IPAQ). The volume of the different levels of physical activity was calculated in units of MET min/wk.Results: The total volume of weekly physical activity was higher among high school students living in a town (Czechowice-Dziedzice) than students living in a city (Katowice). Only 31.5% of the students met the criteria for recommended physical activity.Conclusions: The level of physical activity varies by place of residence. Students living in towns are more physically active than youth living in cities. Most high school students (64%) included in the research can be considered to be insufficiently physically active.

International Physical Activity Questionnaire (IPAQ) has become one of the world's most valuable tools for measuring physical activity in different groups or populations.The relationship between regular, moderate-intensity physical activity and health parameters including physical fitness and aerobic capacity has been clearly proven by numerous investigations throughout the world.The aim of the present study was to determine the magnitude of differences in absolute & relative (lxmin-1, mlxkg-1xmin-1) VO2 max, by using the Astrand-Ryhming normogram in students aged 19 to 24 years, depending on their weekly energy expenditure (METminxweek-1), as diagnosed with IPAQ.The significance of differences in aerobic capacity between highly and moderately active students was evaluated. The Pearson correlation coefficient was calculated as a measure of the strength of the correlation between the above parameters in female and male groups.VO2 max was significantly higher in male and female participants, with a high level of physical activity, as determined through IPAQ criteria.

The aim of the present study was the evaluation of habitual physical activity in adult members of health promoting associations in compliance with selected health recommendations. Physical activity was monitored for 7 consecutive days using accelerometer ActiGraph GT3X+. It was observed that the percentages of individuals with sufficient physical activity differ depending on healthoriented recommendation used in the evaluation. The results indicated that despite appropriate weekly volume of physical activity expressed in energy expenditure (on the average, twice as high as the recommended minimum) and the number of steps taken daily, the prevailing majority of participants (60%) demonstrated an inadequate level of it when assessed in the context of recommendation by World Health Organization.

The differences in human motor development are determined by predispositions and living conditions. The aim of the present study was to examine relationships between motor fitness of children and adolescents aged 8-16 years (277 boys and 247 girls), and their somatic build and quality of life of their families. Body height, body mass and skinfold thickness were measured. On the basis of these measurements body mass index (BMI), Rohrer's index and lean body mass (LBM) were calculated. The subjects' physical fitness was also assessed with motor tests: speed of arm movement (plate tapping), agility (10 × 5 m shuttle run), explosive strength of the legs (standing broad jump), trunk strength (situps), explosive strength of the trunk and shoulder girdle (1-kg medicine ball throw), and flexibility (sit and reach) regarded as a morpho-functional predisposition of motor abilities. The standing broad jump results were then used to calculate maximal anaerobic power (MPA). The examination was completed with a questionnaire survey of the children's parents concerning their families' quality of life. On the basis of the parents' answers to the questionnaire, two quality of life indices were constructed: objective quality of life index and subjective quality of life index. Due to the wide age bracket of subjects the sample was divided into two age groups: 8-12 and 13-16-year-olds. The relationships between subjects' motor development, somatic traits and their families' quality of life were examined with the use of multivariate comparative analysis. The level of motor development of studied children was more strongly determined by their somatic build than the quality of life of their families. The most important somatic determinants of the subjects' motor abilities were body height and subcutaneous adiposity. These determinants primarily affected speed and strength abilities of younger school children. Objective quality of life of children's families determined the development of some strength abilities in children aged 8-12 years. No correlations between the subjects' motor development and subjective quality of life of their families were found.

Backround: The aim of this study was the assessment of energy expenditure (EE) and the intensity of physical activity (PA) of adult women during the interactive dance video game (IDVG) Dance Central on Xbox 360 Kinect in the context of health recommendations. Methods: Twenty eight intentionally selected women (mean ± SD age: 21.8±1.1 years, body height: 167.3±6.1cm, body mass: 59.3±5.9 kg, body mass index: 21.2±1.3) met the inclusion criteria and took part in to the experiment. Heart rate monitor, accelerometer, and pedometer were used as measurement tools. Participants performed the same easy dance routine three times (for a total of 10 min.). Trials consisted of imitating the motions presented by the virtual dancer. Results: The data from accelerometer and heart rate monitor were similar, and indicated the moderate intensity of interactive dance video game (IDVG) Dance Central. However, energy expenditure assessed by pedometer was significantly lower. Conclusion: IDVG Dance Central may be useful in increasing the daily dose of physical activity of adult women and meet the health-related recommendations provided its regular practice.

Study aim: the objective was to assess and compare the energy expenditure (EE) and exercise heart rate (EHR) during Nordic Walking (NW), and conventional walking (W) in physical education and tourism/recreation university students. Material and methods: a total of 53 women and 65 men, students at the Academy of Physical Education in Katowice, and Polytechnic in Opole, in Poland, were investigated to assess the EE of Nordic Walking and conventional walking, and to measure the EHR, a uniaxial accelerometer – Caltrac Monitor, and a pulsometer – Polar RS 400 SD were used. After a standard warm-up, the participants (joined group) were marching with poles for 30 minutes, at a speed regulated by the group’s leader, who used footpod’s indications: 5.5–6.5 km/h – in Katowice, and 7.5–8.5 km/h – in Opole. After a break, during which the participants’ heart rate decreased below 100 bpm, the above actions and measurements were repeated, during normal walking. Results: energy expenditure during Nordic Walking (EE NW), expressed in kcals and METs, was in women and in men, at both analyzed speeds, significantly higher (p < 0.05) than during conventional walking (EE W). EHR was higher during NW, compared to W, and the statistically significant differences were revealed both in female’s and male’s groups. Conclusions: our study data have shown that EE and EHR during Nordic Walking, have been significantly higher than during conventional walking, regardless of the moving speed and gender. NW might present a useful modality in prevention of hypokinetic disorders.
