Study aim: To improve the teaching of football techniques by applying cognitive and imagery techniques.Material and methods: Four groups of subjects, n = 32 each, were studied: male and female physical education students aged 20 - 21 years, not engaged previously in football training; male juniors and minors, aged 16 and 13 years, respectively, attending mastery School of Sports (football); their training experience amounted to 6 and 3 years, respectively. Every group was divided into two subgroups (n = 16 each) - control and experimental. All subjects underwent a course consisting of 40 sessions lasting 90 min each, once weekly. Before and at the end of study period the participants were subjected to 3 specific tests assessing their knowledge, motor fitness and game skills.Results: Subjects from all experimental groups achieved significantly (mostly p<0. 001) better results than the respective control groups in all three areas - knowledge, motor fitness and game skills. The levels of acquired knowledge significantly (p<0. 05 - 0. 001) correlated with specific motor fitness and game skills in all groups of subjects.Conclusions: Cognitive approach improves the results teaching football techniques and may serve as a valuable tool in training.

Contemporary sport is becoming more and more commercialized, hence the players strive to win at all costs, and to achieve this goal, they consider all means to be allowed. In order to be constantly on top, competitors change their training methods, use various aids, and finally direct their interests towards doping. Doping is considered to be the use of substances and all means intended to artificially increase physical fitness during sports competitions, which may be harmful to the ethics of sport or cause mental and physical harm to athletes. The aim of the research is to assess the knowledge of the problem and attitudes of young people practicing sports games towards the dangers of doping. Assessment of knowledge on the effects of the use of illicit means, and analysis of opinion on the use of doping and strengthening mechanisms for the adoption of pharmacological agents. Research on the knowledge about the use of support measures and doping in sport was carried out among talented youth practicing team sports games in randomly selected clubs of Małopolska, Silesia, Podkarpacie and Opole. Continuation studies were conducted in 2018-2020, they covered 60 girls and 60 boys, aged 16 years. The research was carried out using a questionnaire, the questions of which concerned the following problems: knowledge of the essence of sports doping, the relationship between doping and the principle of fair play in sport, support used in physical recreation, reasons for the use of doping, moral and criminal liability in the use of doping. When analyzing the results of the research, it should be noted that the use of doping in sport is negatively perceived by the examined youth. However, it can be assumed that the knowledge about the support and the problem of doping in sport is insufficient. Setting the main goal - sports success and the related financial rewards, as well as the willingness to be the best in the opinion of the respondents may narrow the boundaries, which may facilitate the decision to use support and doping. These observations seem to be very disturbing, as the analysis of research data concerns young people practicing sports at the stage of education and the utilitarian nature of physical activity.

The paper presents an application of phosphatidylcholine 45% (PC 45) and polyvinylpyrrolidone (PVP) in formulations of magnesium salts such as Mg(VitB6) and Mg(VitB6Arg) prepared by solid dispersion (SD) techniques. The evaluation of influence of the selected carriers on some physicochemical properties of solid dispersions and on the absorption process of Mg +2 ions in vitro were made. An infrared (IR) spectra study suggested creation of a hydrogen bond between the carriers and the examined magnesium salts. The results of the following thermal analysis: differential thermal analysis (DTA), thermogravimetry (TG), and differential scanning calorimetry (DSC) showed that application of PVP into SD lower the temperature of the decomposition process. However, in the case of PC 45 into SD the characteristic thermal effects of higher temperatures were observed. Moreover, values of the enthalpy SD of decomposition process were decreased. The results of these studies on absorption process of Mg2+ ions in vitro showed the positive influence of the applied carriers on the partition coefficient values (log P) in the examined formulation.

Proper planning of the training process based on individual LT and AT metabolic thresholds is essential to improve athletic performance. Development of endurance in soccer players is mainly based on continuous runs and variable-intensity runs, supplemented with strength conditioning and sport-specific training. The aim of the study was to analyse selected parameters of physical capacity of soccer players after 8-week variable-intensity running training and circuit training. The experiment was carried out in a group of 34 soccer players aged 21 to 26 years. The athletes were divided into two groups: 17 people in the experimental group and 17 people in the control group. The experimental group was involved in 30-minute tempo runs two times a week for 8 weeks with variable intensity at AT. In the same period, the control group performed two 60-minute continuous runs at the intensity of 70-75%HRmax. The determination of metabolic thresholds used two indirect tests: the multistage shuttle run test (beep test) and maximal lactate steady state test (MLSS) with author's own modification. In order to evaluate maximal heart rate (HRmax), the research procedure was started from the beep test (distance: 20 m). The speed at the first level was 8.5 km/h and increased with each level by 0.5 km/h. Training of the experimental group where variable exercise intensity was used caused a statistically significant increase in HRmax (by 1.9%) and blood lactate levels at the AT (by 20.5%). The training in the experimental group led to the statistically significant (p < 0.05) increase in the parameters of the following variables: HRmax (by 1.9%); lactate level (by 7.85); HR at the AT (by 1,9%); lactate level at the AT (by 20.5%). The assumptions of the experimental training did not cause statistically significant changes in pretest vs. posttest HRmax and blood lactate levels for the LT. Endurance training with high intensity is more effective in soccer players compared to training with moderate intensity. Development of special endurance in soccer should also assume the intensity and method of working similar to the method used during sport competition.
