Introduction and objective. Many studies have indicated numerous nutrition mistakes among school-aged children and adolescents in both urban and rural environments. The aim of this study was to assess the nutritional habits of the Polish population, consisting of 7,974 individuals aged 12–17, from rural and urban environments, as well as to identify environmental variations of these habits and to verify the existing information on the incorrect nutrition of school-age children and adolescents. Materials and method. The research covered a group of 7,974 respondents – school-age adolescents with a similar age structure (12–17 years). The study on subjects from secondary school grades 1 – 3 was conducted in randomly selected schools from 2 random Polish provinces; 5 counties were randomly selected, followed by a choice of 2 communes: one rural and one urban. The research technique was a self-designed survey questionnaire. The obtained results were subjected to statistical analysis using the Pearson Chi 2 and V Cramer test. Results. The research revealed environment-based differences in subjects’ nutrition. Breakfast was consumed daily by a statistically significantly fewer subjects from the rural environment (36.31%) than from the urban areas (51.32%); second breakfast was consumed by an insignificantly smaller proportion of respondents from the urban environment (40.00%) than from the rural one (46.00%); dinner was eaten daily by 86.00% of urban subjects and 82.00% of rural respondents; afternoon tea and supper were eaten rarely by respondents from both environments. The diet of respondents was dominated by anti-health behaviours. Conclusions. Most of the respondents displayed incorrect nutritional behaviours. Nutritional mistakes occurred among respondents from both rural and urban environments, with the predominance of the rural areas.

Objectives. The aim of this study was to discover the relationship between the performance of different mechanical movements of rowers, and define its effect on the motor programs of the cyclic movement in athletes living in rural and urban areas. Materials and method. Twenty-two male rowers participated in the experiment using a rowing ergometer (Concept2, USA). The experiment consisted of 3 tests examining the maximal power of the pull-ups (MPbpu). The movement mechanogram was registered with a specialized complex Noraxon’s 3D MyoMotion (Noraxon Inc., USA). The software of the complex allowed calculation of the values of the joint angles from the accelerometer data. The Origin Lab 8.5 program was used for the mathematical and statistical processing of the signals from the mechanograms. Results. It was found that all experiment participants had a stepped controlled increase in the power of single bar pull-ups leading to a corresponding proportional increase in the frequency of rowing – test 1 and, conversely, a stepped controlled increase in the rowing frequency accompanied by a proportional increase in the power of the bar pull-ups – test 2. The involuntary dependence of the power and the rate was due to the peculiarities of the central cyclic movement programming, according to which the forces and durations of the active and passive bar pull-ups phases were interconnected and regulated together. The voluntary power-rate dependence control led to the breakdown of these links in the motor program of cyclic movements and to the separate control of these parameters. Conclusions. Motor programs in cyclic movement may be created in the same pattern in tope level sport and recreation, as well in different environmental conditions – gym halls (movement simulators), professional and recreational water sport tracks.
