Parkour is a growing sport that mostly involves jumping, vaulting over obstacles, and climbing in a non dedicated setting. The authors gathered all known relevant literature across miscellaneaous academic fields in order to define parkour with regards to other sports disciplines.Parkour is a lifestyle sport, and as such provides an alternative to mainstream ones, away from strict rules, standardized settings, and necessary competitions. Traceurs (parkour adepts) consider the city as a playground and as an outlet for their creativity, but they also have a strong taste for hard and individualized challenges. They usually train on non specific structures, at ground level. Although their social background is not clear, they are mostly young and male.Traceurs are stronger than recreational athletes, especially in eccentric exercises. However, their endurance skills may be below average. One of the core specificities of parkour is its precision constraint at landing, which turns a standing long jump into a precision jump, regulated on-line so as to prepare for landing. The running precision jump follows the same landing pattern, and its flight phase contrasts with long jump techniques. Injuries, which are not more frequent than in other sports, often occur at reception and on lower limb extremities. This risk is coped with targeting the landing area with the forefoot instead of letting the heel hit the ground like in gymnastics, or with rolling in order to dissipate the impact. Overall, parkour focuses on adaptability to new environments, which leads to specific techniques that have not yet been extensively addressed by the literature.

We present a methodology to simulate the impact of the atmospheric models in the background particle flux on ground detectors using the Global Data Assimilation System. The methodology was within the ARTI simulation framework developed by the Latin American Giant Observatory Collaboration. The ground level secondary flux simulations were performed with a tropical climate at the city of Bucaramanga, Colombia. To validate our methodology, we built monthly profiles over Malargüe between 2006 and 2011, comparing the maximum atmospheric depth, X<sub>max</sub>, with those calculated with the Auger atmospheric option in CORSIKA. The results show significant differences between the predefined CORSIKA atmospheres and their corresponding Global Data Assimilation System atmospheric profiles.

The Impact

The main purpose of this study was to determine the impact of somatotypic profile and body mass index on the physical conditions of 12-14 year-old students, based on the results of tests for assessment to motor skills included in assessment system at the Physical education and sports in schools. The 64 young men and 70 girls we will explore are from two different schools in Blagoevgrad, which subsequently were divided into four groups: two groups for the boys and two for the girls. The study groups have antropometrichal parameters: height - 161.5 ± 8.2 cm, weight - 55.25 ± 18.26, and BMI of 21.01 ± 5.82 (M ± SD) for the boys and height 159.7 ± 7.22 cm, weight 52.02 ± 10.66 and BMI (kg / m2) 20.36 ± 3.85 (M ± SD) for the girls. The participants of this study completed 4 tests to determine the level of physical fitness, which are included in the System for Control and Assessment of the Achievements of the Students in Physical Education and Sports, used in the second stage of the primary education in Bulgaria until 2019 year. The functional tests were: for boys they are: 50m (sec) sprint running; 600 m (sec) for endurance; throwing a medicine ball 3 kg (cm) and standing long jump with both feet. For the girls: 50m (sec) sprint; 300m (sec) for endurance; sit ups (pc) and standing long jump with both feet (cm). The Score are from 1 to 5, depending on the value of the result. The somatotype was measured using the Heath-Carter method. The results show mean values for endomorph of 4.44 ± 1.47, for mesomorph of 4.94 ± 2.4, and for ectomorph of 3.12 ± 1.57 for the girls (mesomorph-endomorph) and values (M ± SD) of 3, 50 ± 1.58 for endomorphism, 5.74 ± 3.04 for mesomorphy and 3.28 ± 1.77 ectomorphy for the boys (balanced-mesomorph). We used GraphPad Prism version 3.0, for statistical analysis. The correlations between somatotype index, body mass index, and results of functional tests were calculated by coefficient of Pearson (p<0,05). We checked all possible relationships between ectomorphic, mesomorphic, and ectomorphic index with condition test results. Only 6 of them having significant correlation: between mesomorph and result of 50 m at Male7 r = 0.331, p = 0.048; between the ectomorph and the result of 50 m at Female7 r = -0.346, p = 0.045; between endomorph and 50 m result at Female7 r = 0.459, p = 0.006; between the endomorph and the result of a jump from the site at F7 r = -0.414, p = 0.0015; between mesomorphs and the result of a standing long jump of Female7 r = -0.519, p = 0.0016; between ectomorphs and a score of 50 m at Female1 r = -0.3359, p = 0.043 (Pearson). The most significant correlation was found between the BMI index and the 50 m result at Male7 r = 0.832, p <0.0001 (Pearson). We identified 11 of a total of 64 possible combinations; five of which between functional capability, BMI and six with somatotype index; five were low correlations (0.3–0.5) in the range r = 0.300– 0.340; only three high positive correlations were found in the range r = 0.693 - 0.832, p <0.0001 (Pearson); seven correlation dependencies were established with the result of the test for 50 m (sec); three with a jump test (cm) and one with 600 m (sec). In conclusion we can say that our hypothesis is not confirmed, because despite the normal weight, BMI and good somatotypic profile of the subjects , they have no statistically significant effect on the functional capabilities of students.

In order to actively respond to the government’s call to scientifically create campus football culture, combine the characteristics of football sports, and improve people’s understanding of the mental and intellectual functions of football, this article focuses on the impact of football training on physical function and football technology. Based on the understanding of related theories, the experiment on the impact of football training on physical function and football technology was carried out. The experimental results showed that the weight, height, and BMI increased significantly during the period of football training ( P < 0.05 ). The independent sample T test showed that there were no significant differences in height, weight, and BMI between the two groups before and after training; the standing long jump performance of the control group after training showed an upward trend, but the significance level was not statistically significant. Three months later, the time for the experimental team to complete the eight-character dribble test in football training was reduced from 20.51 seconds to 15.57 seconds. The independent sample T test found that there was no significant difference in the physical fitness of the two groups before training and the changes in football skills of the subjects before and after training. Then, the clustering algorithm in the big data was used to analyze the data of the experimental group. The standing long jump has the highest performance; the second category belongs to the third level, and the third category belongs to the second level.

Research in preschool children that investigates the impact of different exercise interventions on physical fitness is limited. This pre–post study was aimed at determining if participation in a nine-month structured multisport program (MSG; n = 38) could enhance physical fitness components compared to a formal exercise program (control group (CG); n = 36) among preschool children. Physical fitness was assessed using standardized tests (the standing long jump, sit and reach, 20 m sprint, sit-ups for 30 s, bent-arm hang, medicine ball throw (MBT), grip strength, 4 × 10 m shuttle run, and 20 m shuttle run tests). The structured multisport program involved fundamental/gross and fine motor skills and ball game-based exercises twice a week. The control group was free of any programmed exercise except for the obligatory program in kindergartens. A mixed ANOVA demonstrated significant group-by-time interaction effects for the 4 × 10 m shuttle run, standing long jump, sit-ups, bent-arm hang, grip strength, and sit and reach tests (p < 0.05). There was no significant group-by-time interaction effect for the 20 m sprint test (p = 0.794) or for the 20 m shuttle run test (p = 0.549). Moreover, the MSG and CG performance in the MBT and 20 m shuttle run tests improved to a similar extent from pre- to post-test. Our results indicate that compared to the formal plan, the structured multisport program led to a sustained improvement in physical fitness in healthy 5-to-6-year old children.

The paper provides an overview and review of the use, knowledge and importance of cannabidiol (CBD) on stakeholders in the sports system, on the example of members of the Sports Community of the City of Zadar. In particular, a review is given of the possible harmfulness of taking substances that contain prohibited amounts and ingredients for athletes, ie unfounded and unconfirmed independent research. The method and purpose of taking cannabidiol by the stakeholders of the sports system are presented, with special reference to athletes in the field of recreation. The survey, through a questionnaire, determined whether athletes and sports professionals are sufficiently aware of what are cannabidiols, and what is the impact on the health status of athletes when using cannabidiol and the possible harm to the health of athletes in uncontrolled cannabidiol intake. In conclusion, research has shown that athletes and sports professionals do not know enough about what are cannabidiols, and what is the impact of their use on athletes and recreational athletes. Therefore, the conclusion is that it is necessary to educate these stakeholders in sports and conduct future research.

Development of the e-commerce sector in Poland over the last decade has been extremely dynamic. Both its value and share in GDP have increased, and the growth rate of on-line retail sales in Poland is currently one of the highest in Europe. The market development is driven either by changes in the behavior of consumers who are increasingly shopping online, as well as by growing number of e-stores. The main objective of this article is to identify the key factors determining purchasing decisions in the e-commerce sector in Poland by assessing the impact of differences in the characteristics of generations on their preferences regarding e-commerce. Each generation is significantly different from each other in terms of work, education, security, success in professional and personal life, as well as in terms of consumption. The characteristics of individual generations and the level of their digital competence have a significant impact on the way in which a given generation makes purchases and what is expected in the purchasing process. In order to establish the key determinants of on-line purchasing decision, a method of on-line survey was used. The quota sample included three generations of Polish Internet users: 260 people at the age between 25-37 (generation Y); 200 people at the ages between 38-50 (Generation X) and 100 people at the age between 51-70 (baby boomers generation). The structure of the article includes a presentation of the problem against the background of relevant literature, theoretical assumptions of the research, its findings, discussion and conclusions.

ned: 1) the smallest increase in the standing long jump was observed in the group in which there were trainings with elastic training bands – 4,3 cm; in the group where isometric exercises were used, the increase in standing long jump was 10,9 cm; in the group in which students trained with weights, the increase in the standing long jump was 14 cm; 2) the increase of the leg press index at an angle of 45° in the group that used elastic training bands as a means of weighting was the lowest, i.e. 14 kg; in the group performing isometric exercises it was the highest – 19,5 kg; in the group that used weights – 18 kg. Purpose: to research the effectiveness of elastic training bands (resistance bands) application to develope explosive strength in a comparative aspect. Material and methods: theoretical material for the article has been taken from the research of Ukrainian and foreign scholars and experts. The basis for the study was a research laboratory of functional diagnostics and physical rehabilitation. The study involved 60 18-19-year-old students (40 girls and 20 boys), young people with excellent, very good or good health status. The main methods used for the experiment and the article were comparison, questionnaires, final tests, statistical analysis (parametric and nonparametric analysis, systematization, creation of varieties (arrays), determination of Student’s t-test and Pearson’s χ2 test). Results: the questionnaire of students on the expected effectiveness of various ways of explosive strength training revealed that the lowest result was expected from isometric exercises (5%), the average one was found out from the use of weights (61,67%), and the highest result was shown from the application of elastic training (resistant) bands (65%). According to the results of the experiment the following data has been obtained: 1) the smallest increase in the standing long jump was observed in the group in which there were trainings with elastic training bands – 4,3 cm; in the group where isometric exercises were applied, the increase in standing long jump was 10,9 cm; in the group in which students trained with weights, the gain in the standing long jump was 14 cm; 2) the increase of the leg press index at an angle of 45° in the group that used elastic training bands as a means of weighting was the lowest, i.e. 14 kg; in the group performing isometric exercises it turned out to be the highest – 19,5 kg; in the group that used weights – 18 kg. Conclusion: our experiment involved comparing the impact on the explosive strength development of different means of weighting: elastic training bands, isometric exercises and weighting objects. Despite the expectations of the respondents it was demonstrated that the application of the elastic training bands does not have a significant advantage over other means of weighting. The resistance bands application show lower results compared to the training with the isometric weighting and weighting of objects. The application of exercises in the isometric mode of weighting showed a significant gain in explosive strength, although the expected results were not met. The application of objects’ weighting showed the expected high results. Therefore, the prediction of the high efficiency of elastic training bands as a means of weighting turned out to be spurious
