Motor abilities, such as endurance and the optimal level of physical activity, play a fundamental role in football as they are necessary to maintain the high effectiveness of the training process. The aim of this study was the observation of the trend of changes in the level of cardiorespiratory endurance of young football players in a one-year cycle overlapping with the COVID-19 lockdown and an assessment of the impact of the training intervention during home confinement. The participants of the study were 24 young football players. We analysed the results of the study in a one-year training cycle (lockdown from 11 March 2020 to 6 May 2020). The cardiorespiratory endurance was measured using the Multistage 20 m Shuttle Run test—Beep Test. A repeated measures analysis of variance was used in the study. Detailed comparisons were made using Tukey’s HSD test. Statistically significant differences were noted in endurance in a one year cycle: F(5.115) = 22.65; p < 0.001; partial Eta-squared = 0.50. An increase in the level of endurance by mean = 179.17 m, SD ± 189.87 m was noted between T1 and T6. After the break caused by the COVID-19 restrictions, a decrease in the level of cardiorespiratory endurance was noted. Only after two training mesocycles was a significant increase in the mean value noted compared to the period before the pandemic (p < 0.05). With the negative impact of restrictions in mind, coaches and physiotherapists should exercise caution when planning training, taking into consideration the level of physical activity during the pandemic.
Background Strength and balance are important factors for soccer players to be successful. This study’s aim was to determine the relationship between lower-limb muscle strength and balance control in elite male soccer players (n = 77). Methods Concentric isokinetic strength (peak torque of quadriceps (PT-Q) and hamstrings (PT-H), hamstrings/quadriceps (H/Q) ratio) was measured for the dominant and non-dominant leg at angular velocities of 60°s−1and 240°s−1, as well as the total work for extensors (TW-Q) and flexors (TW-H) for both legs (at an angular velocity of 240°s−1only). Balance score (BAL score) was used for unilateral assessment of balance control using a Delos Postural System Test measurement tool. Hierarchical multiple regression analyses were performed to predict balance control using isokinetic knee strength performance for dominant and non-dominant legs. Results Final modelling included peak torque of hamstrings at 240°s−1 and peak torque of the quadriceps at 240°s−1 for the non-dominant leg (R2 = 19.6%; p ≤ 0.001) and only peak hamstring torque at 240°s−1 for the dominant leg (R2 = 11.3%; p = 0.003) as significant predictors of balance score. Conclusion Findings indicate that balance control is widely influenced by peak hamstring torque and peak quadriceps torque at high angular velocity particularly in the non-dominant leg i.e., the supporting leg in soccer players.
There is a trend in soccer to ensure comprehensive player preparation including fitness, technical and tactical, as well as mental aspects. It has been emphasized many times that personality traits (neuroticism, conscientiousness, extraversion) are significant for the effectiveness of performance in soccer. The question of why these relations occur has been considered relatively rarely. Therefore, the aim of this study is an attempt to explain these relations through introduction of ways of coping with stress as their significant mediators. It is hence assumed that players with certain personality traits are characterized by specific ways of coping with stress which are related to the effectiveness of their performance. The study group consisted of 122 players, aged 16–19 years. The participants of the study were youth teams at the championship level (medalists of the youth Polish Championships), and the following research tools were used: NEO-FFI Personality Inventory, The Coping Inventory for Competitive Sport (CICS) and Szwarc’s Observation Sheet for effectiveness in soccer. It was demonstrated that task-focused ways of coping with stress (effort expenditure, thought control, and logical analysis) were the most frequent mediators of relations between the studied traits and the effectiveness of performance of soccer players.
The assessment of footballers effectiveness is the key element of control at every step of their training, regardless of on what level they are. What seems essential is the prediction of footballers' actions, the height of which is achieved in the time directly preceding taking part in competition. Therefore, twenty footballers took part in the study which involved efficiency tests concerning maximum speed in 5 meters and 20 meters races as well as endurance measured by Beep Test. The tests were conducted at the end of lead time. Additionally, the effectiveness of action was measured in the initial perdion. No significant correlations were found between the tested variablesspeed tests and effectiveness of game. A significant relationship was found only between the endurance measured by Beep Test.Summing up, the only factor significantly correlated to the effectiveness of footballers' action was endurance and it can be therefore seen as crucial in terms of motor preparation, at the tested sport level.
Introduction: Infectious diseases are still a significant medical and social problem in the contemporary world. The most effective and at the same time the least expensive way to become protected against infectious diseases is vaccinations. Appropriate education of the society referring to the prevention of infectious diseases such as measles, diphtheria, or pertussis can contribute to changing the attitudes of many parents to mandatory and recommended vaccinations. Aim of the research: The analysis of the impact of the level of knowledge on making decisions about administering preventive vaccinations. Material and methods: The study included 370 participants (308 women and 62 men). They were students of Lublin universities and young parents living in the Lublin voivodeship. The research tool was an author-made questionnaire consisting of 20 closed questions. For the statistical analysis of research results the methods of descriptive statistics, the χc 2 test, and Cramer's V correlation coefficient were used. Results: As many as 98% of the respondents exhibiting a higher level of knowledge declared future regular vaccinations of their children in accordance with the official recommendations. Among people with a low level of knowledge, only 45% declared such regularity in their children's vaccination. As many as 62% of the respondents who lacked knowledge on vaccinations failed to have voluntary vaccinations administered. In comparison, among those with high level of knowledge, 50% never had recommended vaccinations administered. Conclusions: The level of knowledge has a significant impact on the decisions on administering preventive vaccinations in the studied population. Respondents who had a higher level of knowledge more frequently declared administering vaccinations regularly, both to themselves and their children. Streszczenie Wprowadzenie: Choroby zakaźne są nadal istotnym problemem zarówno medycznym, jak i społecznym we współczesnym świecie. Najskuteczniejszą i jednocześnie najtańszą metodą zabezpieczenia się przed chorobami zakaźnymi są szczepienia ochronne. Odpowiednia edukacja społeczeństwa w zakresie zapobiegania chorobom zakaźnym, takim jak odra, błonica, krztusiec, może się przyczynić do zmiany postawy wielu rodziców wobec szczepień obowiązkowych oraz zalecanych. Cel pracy: Analiza wpływu poziomu wiedzy na decyzje o wykonywaniu szczepień ochronnych. Materiał i metody: Badaniem objęto 370 osób (308 kobiet i 62 mężczyzn), studentów lubelskich uczelni oraz młodych rodziców zamieszkujących województwo lubelskie. Narzędziem badawczym była autorska ankieta wywiadu zawierająca 20 pytań zamkniętych. Do analizy statystycznej wyników badania zastosowano metody statystyki opisowej oraz test c 2 i współczynnik korelacji V Cramera.
