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.

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.

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.

The aim of the present study was to evaluate the efficacy of 3-week high intensity interval training in normobaric hypoxia (IHT) on aerobic capacity in basketball players. Twelve male well trained basketball players, randomly divided into a hypoxia (H) group (n=6; age: 22±1.6 years; VO2max: 52.6±3.9 ml/kg/min; body height - BH: 188.8±6.1 cm; body mass - BM: 83.9±7.2 kg; % of body fat - FAT%: 11.2±3.1%), and a control (C) group (n=6; age: 22±2.4 years; VO2max: 53.0±5.2 ml/kg/min; BH: 194.3 ± 6.6 cm; BM: 99.9±11.1 kg; FAT% 11.0±2.8 %) took part in the study. The training program applied during the study was the same for both groups, but with different environmental conditions during the selected interval training sessions. For 3 weeks, all subjects performed three high intensity interval training sessions per week. During the interval training sessions, the H group trained in a normobaric hypoxic chamber at a simulated altitude of 2500 m, while the group C performed interval training sessions under normoxia conditions also inside the chamber. Each interval running training sessions consisted of four to five 4 min bouts at 90% of VO2max velocity determined in hypoxia (vVO2max-hyp) for the H group and 90% of velocity at VO2max determined in normoxia for the group C. The statistical post-hoc analysis showed that the training in hypoxia caused a significant (p<0.001) increase (10%) in total distance during the ramp test protocol (the speed was increased linearly by 1 km/h per 1min until volitional exhaustion), as well as increased (p<0.01) absolute (4.5%) and relative (6.2%) maximal workload (WRmax). Also, the absolute and relative values of VO2max in this group increased significantly (p<0.001) by 6.5% and 7.8%. Significant, yet minor changes were also observed in the group C, where training in normoxia caused an increase (p<0.05) in relative values of WRmax by 2.8%, as well as an increase (p<0.05) in the absolute (1.3%) and relative (2.1%) values of VO2max. This data suggest that an intermittent hypoxic training protocol with high intensity intervals (4 to 5 x 4 min bouts at 90% of vVO2max-hyp) is an effective training means for improving aerobic capacity at sea level in basketball players.
