The aim of the work was to define the differences between boys selected for football training and their peers at the beginning stage of different team sports training, as well as those that do not practice any sports discipline. The research material consisted of 97 schoolboys at the age of 10 selected to practice team sports, including football, and 39 non-training boys. All boys attended Szczecin primary schools. Apart from the basic anthropometric characteristics, the following motor skills were analyzed: kinesthetic differentiation, reaction speed, movement frequency, spatial orientation, static balance, maximal lactic anaerobic power, maximal nonlactic anaerobic power, fast muscle activation, aerobic endurance and absolute muscle strength. Not all test results are expressed in SI units. Data obtained through the applied method served as the grounds for defining a profile of a “young football player” as the premise to improve the process of preliminary selection for football. Candidates selected for soccer training presented higher level of kinesthetic differentiation than all other examined boys. They also presented higher level of movement frequency than volleyball players and higher level of space orientation than the not-trained boys. Soccer players nevertheless presented lover level of time of reaction than the candidates selected for basketball training. Results of all condition abilities tests obtained by soccer players were statistically significant better than the one obtained by the untrained boys (p ≤ 0.001) and the candidates for volleyball training (p ≤ 0.05, p ≤ 0.001). The greatest differences were noticed in tests of aerobic endurance and maximal non-lactic and lactic anaerobic power.

Introduction. Carrying out the investigation of community integration (CI) seems to be important part of research in rehabilitation in persons with spinal cord injury (SCI). Researchers point out the need for continuing study of the factors which may modifie level of CI in this group. Aim of Study. The main purpose of this study was to assess the CI level in SCI athletes, participating in individual sports (IS), and team sports (TS). The additional purpose was to identify other variables that determine the level of CI. Material and Methods. The study participants (n = 30) were divided due to practiced sport, into two groups: IS (n = 15), and TS (n = 15). Athletes completed measures of CI: Community Integration Questionnaire (CIQ), and demographic questionnaire (containing information about such variables, as: age in the day of study, time elapsed from injury, level of injury, and level of physical activity – measured by number of hours spent for training per week). Results. There were no significant difference between level of CI in SCI athletes participating in IS, and TS. There were significant difference between physical activity level (measured by number of hours spend for training per week) and one of three subscales, that contains to CIQ. Conclusions. The study results confirmed the need to increase level of physical activity in persons with SCI, and extend research about determinants of CI.

Peroxisome proliferator-activated receptor α (PPARα) is a transcription factor that regulates lipid and glucose metabolism. Accumulating evidence suggests that the intron 7 C allele of the PPARA gene rs4253778 G/C polymorphism has an advantage for power-oriented athletes, presumably due to the hypertrophic effects on skeletal muscle and increase in glucose utilization in response to anaerobic exercise. The G allele, however, is said to be favorable for the endurance-oriented athletes. The metabolic demands of team sports involve aerobic and anaerobic energy pathways, as a result of the intermittent physical activity. The aim of the present study was to investigate the association between the PPARA gene polymorphism and team-sport athletic status. A total of 665 Russian athletes from 14 team sports and 1,706 controls were involved in the case-control study. We found that the frequency of the PPARA C allele was significantly higher in athletes compared to controls (20.5 vs. 16.4%, P = 0.0009), suggesting that anaerobic rather than aerobic metabolism may be crucial to the game performance in team sports. This means that our study indicates the association between the PPARA gene G/C polymorphism and team-sport athletic status. Although more replication studies are needed, the preliminary data suggest an opportunity to use the analysis of PPARA polymorphism, along with other gene variations and standard phenotypic assessment in team sports selection.

Background. Many studies documented an increase in the alcohol consumption among athletes, particularly among representatives of some disciplines, such as team sports. Objective. The aim of the study was to analyse the consumption of alcohol beverages among Polish elite team sport athletes, depending on their sex, age and selected personality traits (general self-efficacy and health locus of control). Material and Methods. The study included 517 Polish team sport athletes (251 women an 266 men). The subjects were examined with an original alcoholic beverage intake survey, General Self-Efficacy Scale (GSES) and Multidimensional Health Locus of Control Scales (MHLC). Relationship between the intake of alcoholic beverages and explanatory variables (sex, age, psychological traits) was determined on multivariate analysis of variance and analysis of regression. Results. Beer turned out to be an alcoholic beverage which the surveyed athletes consumed most often (a few times per month on average). Wine, spirits and alcoholic cocktails were consumed less often (once a month on average). Multivariate analysis showed that consumption of wine, including dry wine, increased significantly with age of the study subjects (p<0.001). Women significantly less frequently considered beer and vodka (p<0.001), whereas men significantly less often preferred wine (p<0.05). The level of general self-efficacy did not influence the intake of alcoholic beverages (p>0.05). Lower levels of Internality were associated with less frequent consumption of beer (p<0.001), and lower scores for Powerful Others with lower intakes of dry wine (p<0.001) and vodka (p<0.01). Lower scores for Chance showed a significant association with lesser preference for alcoholic cocktails (p<0.05). Conclusions. The frequency and structure of otherwise relatively limited intake of alcoholic beverages among elite team sport athletes were influenced by their sex, age and health locus of control.

The problem of evaluating and defining physical endurance of athletes has been the subject of a great body of research and scientific discussion. In team sports, especially football, the energy protection of working muscles in players requires the use of almost all metabolic pathways: aerobic, anaerobic and aerobic-anaerobic. Because of the varying pace of action, the share of energy conversions in muscle cells changes rapidly during a match. Another concern voiced by scientists and football coaches is the question of whether fitness training should always be performed with football balls. The aim of this paper was to present the necessity of monitoring the development of aerobic fitness in football players, and also to answer the question of whether motoric training in football may be performed with balls.

Introduction. Team sports require comprehensive motor preparation of players. In addition to strength and endurance skills, increasing attention is being given to the development of players’ speed skills. Aim of Study. The aim of the study was to evaluate reaction time and 30-metre, straight line sprint time in players selected for the Lower Silesian Regional Teams in Poland in 2013 and 2014. Material and Methods. The study involved 369 players aged 13–15 years (187 girls and 182 boys), members of football, handball, volleyball and basketball Regional Teams of Lower Silesia. Out of this group, 51 players participated in the study in 2013, and then repeated it in 2014. The study used Smart Jump and Smart Speed Systems to measure players’ reaction and sprint times, which were measured at 5, 10, 15, 20, 25 and 30-metre intervals. Results. Mean reaction time to light stimuli observed in boys in 2013 and 2014 was 0.509 ± 0.141 and 0.467 ± 0.264 seconds, respectively. In girls, the mean reaction time was 0.553 ± 0.122 and 0.566 ± 0.0271 seconds in 2013 and 2014, respectively. Mean sprint time in 2013 for boys who were not selected for the Regional Teams the following year was 5.338 ± 0.285 seconds, while those who were selected reached 5.416 ± 0.321 seconds. Girls who did not qualify for the Regional Teams in 2014 achieved the time of 5.764 ± 0.305 seconds. The female players who repeated the study reached the mean time of 5.805 ± 0.28 seconds. Boys who joined the Regional Teams in 2014 had a 30-metre sprint time of 5.533 ± 0.359 s. Boys who were repeating the study achieved the time of 5.322 ± 0.295 s. Girls who were selected for the Regional Teams in 2014 reached 5.796 ± 0.348 s, while girls who were repeating the study – 5.839 ± 0.342 s. Conclusions. The players’ reaction times may suggest that this ability was not a criterion for selecting male and female players for the Regional Teams of Lower Silesia. Male handball players were shown to posses the greatest speed potential.
