Health-enhancing physical activities (PA) performed outdoors could markedly contribute to the adoption of a healthy lifestyle in adolescence. The differences between PA preferences and actual opportunities for these PA are an issue that has received frequent attention. To date, the extent to which these differences are reflected in adolescents meeting PA recommendations and their well-being has not been explored. In total, 10,086 respondents took part in an on-line research project regarding PA preferences. Of them, 2446 also completed the International Physical Activity Questionnaire (Long Form) and the World Health Organization (WHO) W-5 questionnaire to assess well-being. Finally, 1278 of these respondents were involved in objective PA monitoring using pedometers. The study aimed to explore the prevalence and trends regarding outdoor PA. Moreover, we assessed whether the agreement between preferred PA and PA actually undertaken was associated with higher odds for meeting PA recommendations and achieving a higher level of well-being. Of a selection of outdoor activities, Czech and Polish boys preferred cycling, swimming, and downhill skiing, while girls preferred swimming activities, skating, and cycling. The agreement between preferred and PA actually undertaken was associated with higher odds for meeting the weekly PA recommendations and higher levels of well-being both in boys and girls. Evaluation of outdoor PA preferences and taking these preferred activities into account when forming conditions for them was important in the efficient promotion of the physical and mental health of adolescents.

OBJECTIVE: To assess the prevalence and intensity of musculoskeletal pain and to estimate probability of developing playing-related musculoskeletal disorders, depending on risk factors, including gender, years of playing the musical instrument, frequency of practice (number of days per week), average daily practice time, and habitual physical activity level, in young instrumentalists. METHODS: A total of 225 instrumentalists aged 10–18 years, including 107 string-players, 64 keyboardists, and 54 wind-players, were investigated. The Nordic Musculoskeletal Questionnaire (NMQ) together with a numerical visual-analogue pain intensity scale (VAS) was used to assess the participants’ musculoskeletal pain. RESULTS: The young instrumentalists most often complained of pain located in the neck (60.4%), wrists (44.4%), and upper (41.7%) and lower back (38.2%) areas. Girls complained of musculoskeletal pain significantly more often than the boys. A probability of the pain symptoms was increased with each consecutive year of practice (OR 1.135; 95%CI 1.021–1.261). CONCLUSIONS: Musculoskeletal pain in various body parts had already commenced at a young age in our sample of music students, and there was a gender difference (girls were more often affected). Results of our study suggest that an early prophylaxis of playing-related musculoskeletal disorders is needed among young musicians playing the various instruments.

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 × 4 min bouts at 90% of vVO2max-hyp) is an effective training means for improving aerobic capacity at sea level in basketball players.

Aerobic Capacity of Students with Different Levels of Physical Activity as Assessed by IPAQ 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.

Meeting leisure-time physical activity recommendations (especially the criterion of vigorous physical activity) is significantly related to higher self-assessed ability to work among white-collar workers.
