Preparation, Exercising, and Motivation in Sports Practice during COVID-19 Pandemic among Young Football Players in Bosnia and Herzegovina

The Covid-19 outbreak has also led to significant changes in football, such as the suspension of leagues, isolation, and the fact that football players are forced to train on their own. Therefore, the purpose of this study was to determine if there were differences in the level of preparation, practices, and motivation for athletic training among young professional football players during the Covid-19 pandemic, depending on the level of competition. The sample of respondents consisted of 82 young football players from Bosnia and Herzegovina, divided into the first league group (n=47, 18.30±0.62 age) and the second league group (n=35, 17.66±0.73 age). The questionnaire for sports preparation and training (SPEQ) was used, which consists of 11 items and was created according to the existing questionnaire for self-assessment of the level of preparation and type of training of athletes during the training process in the Covid-19 pandemic. Also, a questionnaire on sports motivation during the Covid-19 pandemic was used, consisting of 18 items related to motivation to participate in sports, modified according to the Participation Motivation Questionnaire (PMQ). A five-point Likert scale was used for the questionnaire. The questionnaire was available in electronic form and was sent to the football players through a Google form. The difference was found only in the frequency of the type of exercise in two variables, while there were no differences between the groups of young football players in the other variables of training frequency, level of preparation, and motivation in sports training. It was also established that despite the Covid-19 situation, the motivation for sports training among young football players was at a very high level. © 2023 Montenegrin Sports Academy.

Multivariate Conway-Maxwell-Poisson Distribution: Sarmanov Method and Doubly Intractable Bayesian Inference

In this article, a multivariate count distribution with Conway-Maxwell (COM)-Poisson marginals is proposed. To do this, we develop a modification of the Sarmanov method for constructing multivariate distributions. Our multivariate COM-Poisson (MultCOMP) model has desirable features such as (i) it admits a flexible covariance matrix allowing for both negative and positive nondiagonal entries;(ii) it overcomes the limitation of the existing bivariate COM-Poisson distributions in the literature that do not have COM-Poisson marginals;(iii) it allows for the analysis of multivariate counts and is not just limited to bivariate counts. Inferential challenges are presented by the likelihood specification as it depends on a number of intractable normalizing constants involving the model parameters. These obstacles motivate us to propose Bayesian inferential approaches where the resulting doubly intractable posterior is handled with via the noisy exchange algorithm or the Grouped Independence Metropolis–Hastings algorithm. Numerical experiments based on simulations are presented to illustrate the proposed Bayesian approach. We demonstrate the potential of the MultCOMP model through a real data application on the numbers of goals scored by the home and away teams in the English Premier League from 2018 to 2021. Here, our interest is to assess the effect of a lack of crowds during the COVID-19 pandemic on the well-known home team advantage. A MultCOMP model fit shows that there is evidence of a decreased number of goals scored by the home team, not accompanied by a reduced score from the opponent. Hence, our analysis suggests a smaller home team advantage in the absence of crowds, which agrees with the opinion of several football experts.

Analysis of the COVID-19 Lockdown Impact on Biological Parameters and Physical Performance in Football Players

The COVID-19 pandemic has caused significant changes in global sustainability, but specifically, this study analyses the impact of lockdown on health and behavior in the game of football. The 2020/2021 Italian football competitive season (indicated as "post-COVID”), taking place following an obliged lockdown and longer than the normal summery season break, was characterized by very short recovery times and was compared to the 2018–2019 "pre-COVID” season, which had a regular course. The comparisons were about anthropometric and hormonal responses, muscle damage, and the physical performance of players in the major league (Serie A), and were made considering two extreme points of the competitive seasons: before the preparatory period (T0) and at the end of the season (T1). Turning to the results, it is significant to note the following: (1) body fat percentage was lower at the start (T0) of the post-COVID season than at the start of the pre-COVID season. During both seasons, serum CK and LDH increased in T1 and were significantly higher in both T0 and T1 of the post-COVID season. (2) Cortisol and testosterone concentrations increased in both seasons from T0 to T1;however, in the post-COVID season, concentrations of both were higher than in the previous season. The testosterone to cortisol ratio increased at the end of the pre-COVID season, whilst strongly decreasing at T1 of the post-COVID season. (3) Blood lactate concentrations significantly decreased during the pre-COVID season but remained unchanged during the post-COVID season. We may conclude that the enforced suspension period and the consequent rapid resumption of all activities influenced the physical and physiological state of professional footballers.

Home team's advantage reduced without crowd support after the COVID-19 outbreak

Historically, fan attendance at sporting events has always been considered an advantage for the home team. The level of fan attendance at soccer matches was evaluated as a decisive effect to modify the performance of the home teams in the most important soccer leagues around the world. We exploit the effects of the absence of spectators driven by COVID-19 pandemic mitigation policies. We find that the advantage of the home field, measured by the proportion of wins and also by the numbers of goals and points scored, is remarkable in many leagues. We performed comparative hypothesis tests with eight of the world's top soccer leagues, confirming a decrease in the probability of a home win, greatly affecting the matches´ outcomes.

Lessons learned from the COVID-19 pandemic: implications for semiprofessional soccer clubs after the crisis- a team study

In 2019-2020 and 2020-2021, the COVID-19 pandemic led to unexpected behavioral restrictions, allowing only the individual training of the athletes. The purpose of the present study was to record the effects of a home-based training program on physical performance at a semi-professional level, after the Covid-19 confinement, in terms of external load. Twenty soccer players from one semi-professional team participated in this study. The data was collected by GPS devices, with an accelerometer and gyroscope, and a sampling rate 10Hz. The external load is evaluated by the total distance, the high-intensity runs, the sprint distance as well as the number of accelerations and decelerations. Three matches before and twelve games after the lockdown were analyzed and compared. During the confinement period, the players performed 5-6 training sessions per week. This period lasted over 4 four months. The training sessions were monitored by a free smartphone application. Similarly, the players communicated with the technical staff with a free internet application. The results showed significant increases (p < 0.05) in the total distance covered during the matches after the intervention. No significant increase in high-intensity runs and the number of accelerations were found (p > 0.05). The present data suggest that an intervention monitored by a free application could improve athletic performance at the semi-professional level, even after long-term abstinence from team training such as quarantine or off-season periods. These data might provide affordable solutions to the semi-professional soccer teams, which could be used during the off-season period leading to reduce detraining effects and higher performance in the forthcoming championship.

Match Performance Statistics Related to Winning of Chinese Super League Under Different Match Stages

This paper aims to determine relationships between 160 matches statistics and the match results in two match stages of 2020 CSL under the COVID-19 pandemic prevention and control. A team's winning probability was evaluated by a two-standard-deviation increase in the value of each variable. The smallest worthwhile change was used to evaluate nonclinical magnitude-based inferences. The results showed that for group round robin stage, nine match statistics had clearly positive effects on the probability of winning (Shot, Shot on Target, Shot from Set Piece, Cross Accuracy, Counterattack, Won Challenge, Tackle Gaining, HIR Distance in BP, Sprinting Distance in BP), two had obviously negative effects (Distance Covered in Penalty Area, Sprinting Distance Out of BP), other twenty-three statistics had either trivial or unclear effects. While for the knockout stage, the effects of nine match statistics (Pass Accuracy, Forward Pass Accuracy, Delivery into Attacking Third, Delivery into Penalty Area, Dribble into Attacking Third, Corner, Foul Committed, Yellow Card, Distance Covered in Attacking Third) turned to clearly positive, the effects of Won Challenge, Cross Accuracy turned to trivial and clearly negative, respectively. Coaches and players should take these different aspects into account when planning practices and competitions for their teams. © 2023 SPIE.

'Why now' for AFLW? Providing a new affirmative narrative for women's football in the post-COVID world

As with many other male-dominated sports, for over a century of its history, Australian Rules Football organizations resisted and undermined women's participation in the game. The first league for women footballers commenced in Victoria in 1981. Since then, the growth in women's participation has been substantial, and in 2017, a professional women's Australian Football League (AFLW) commenced. The next phase of the participation of women in football is approaching, and heralds an opportunity for women to (re)gain power within the sport. In October 2019, thirty percent of women players rejected the proposed Collective Bargaining Agreement from the Australian Football League (AFL), with the underlying sentiment of wanting a stronger voice in the vision for the future of their game. This paper examines how changing participation rates in community football can transform the narrative of women's football from one of subsidized welfare to women players being necessary for the survival of football.

Soccer-Related Violence: The Police Response in Australia and in the United Kingdom

The apparent growing popularity of soccer, as a spectator sport, in Australia makes this an opportune time, especially after the 2020 COVID-19 pandemic shutdown, to investigate its roots and comment on its future. The current A-League is the most successful incarnation of domestic soccer in Australia to date. As spectator numbers increase, clubs, stadium managers, spectators, police, and private security providers will play pivotal roles in the management of the sport. This paper draws on archival data from newspapers, official inquiries, football literature and statistical data to map the history of disorder and disasters at soccer matches in several countries. The causes of the disorder are complex and range from inadequate crowd control strategies to infrastructure failures. This paper examines both Australian and European history to map the effects of disorder at soccer matches and what tactics the police use to mitigate or reduce it. This mapping exercise concludes that all countries should adopt an approach of prevention rather than cure to overcome soccer's bad reputation, returning it to a family oriented recreational activity while maintaining high levels of safety and security in football grounds. The chapter concludes that to ensure safety and security at football matches, the police need to constantly monitor their tactics and act proactively but fairly to deal with soccer-related violence. This year, as spectators were largely excluded from attendance at live soccer matches during the COVID-19 pandemic, there is a unique opportunity to address problems and issues to ensure the safety and security of football fans into the future. © The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Switzerland AG 2023.

Big challenges, small solution: Microcourses at the University of Oklahoma

[...]microcourses are an ideal vehicle for high-impact, cohort-building projects-experiences that can never substitute for study abroad but that can contribute to a cohesive learning community. [...]the writing assignments consisted of short response papers of 200-250 words in length in German that students posted on the course discussions page to elicit comments and questions from their peers. [...]microcourses provide an ideal workshop-like format for the development of particular linguistic skills that are sometimes overlooked in a language curriculum, such as translation, sustained listening, dramatic reading techniques, or explication of data (Grafikbeschreibung). [...]microcourses are exceptional at fostering a sense of community.

Problem-Based Learning, Social Sustainability, and Soccer

On Friday, March 13, 2020, academic and sport activities at a Mexican university were happening as on a normal day. However, the following Monday, students and teachers had to stay at home for an undefined period. In this work, we show how a course with problem-based learning (PBL) and social sustainability (SS) approaches was adapted to pandemic times. We start with the COVID-19 context at the Monterrey Metropolitan Area (MMA) and then provide a theoretical overview of PBL, SS, Latin American self-produced quartiers, soccer in vulnerable communities, and general aspects about pandemic times. Following this, we discuss the methodology used for reaching out to vulnerable communities in Monterrey City, Mexico, using soccer as a strategy. The students conducted a project together with a non-governmental organization (NGO) whose main task is to promote this sport practice in vulnerable communities around the world. We conclude from our study that students need pedagogical platforms that allow them to respond to the requirements of different social groups, as well as to develop skills to face real problems.

Futures of Change and Futures of Uncertainty: The Impacts of COVID-19 and Movements for Racial Justice in English Football and NASCAR

The sporting world in a post COVID-19 environment will undergo meaningful changes to many aspects of its existence over the next few years. Structural changes to the sport, fan interaction, fan identity, economic impacts on the local communities, and various changes to the physical landscape, are all issues we are likely to see after sporting leagues resume "normal” operations. This chapter seeks to examine how the COVID-19 virus will impact sports from a geographic perspective. What does an overall structural change to a sport mean for local communities' economy and neighborhood identity? This project will offer a better understanding of the social, racial justice, and economic impacts felt at the local level by examining the English Premier league and NASCAR as barometers. This chapter will compare data collected prior to the outbreak of COVID-19 to data collected after, both datasets dealing with similar issues involved with the sports discussed here. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2022.

The impact of the pandemic on sports companies: comparative rate analysis of champions league and Turkish football companies

Today, when sports have become a very important sector for the economy, football, which is one of the favorite elements of the sports sector, has a very large financial position among other sports branches. Many different organizations such as UEFA also contributed to this position. In this study, the effect of the Covid-19 epidemic, which was declared a pandemic by the World Health Organization on March 11, 2020, on football clubs was analyzed through the financial statements of football clubs. In the research, the ratio analysis method was applied through the financial statements of the three football clubs in the category of UEFA champions league leaders as of 5 May 2021 and the football companies traded in the BIST for the periods 2017, 2018, 2019, 2020, and 2021. As a result, it has been revealed that all clubs were affected negatively compared to the pre-pandemic period, but the three clubs, which are UEFA leaders, were less affected by the negative effects of the pandemic due to their strong financial resources and sporting successes. In the evaluation of the research, it has been revealed that Besiktas is the club with the best debt-paying power among the clubs in Turkey. It was evaluated that the net working capital of the other three clubs was negative. It is understood that the three clubs, which are the ranking leaders in 2021, have strong financial positions that do not differ much from each other. It is another result that the solvency and resource structures of Turkish football clubs and UEFA ranking leaders are far from each other. This situation is generally;It can be attributed to sportive success, the difference in the income balance and the increase in the exchange rate in our country.

Under-researched populations and topics in sport and exercise medicine (SEM)

Youth sport, TGNC athletes and mental health Access to athlete mental health care, like physical care, can be considered a resource that allows athletes to function, cope with stress, perform and achieve their goals. In 2019, the IOC established the Mental Health Working Group to develop an assessment battery for the early identification of mental health symptoms and disorders in elite athletes.3 The internal consistency of the mental health assessment battery has been tested in elite athletes, but can the same internal consistency be shown for student athletes?

Economic Sustainability, Management, and Strategies: Analysis of the football clubs of the southern region in the 2022 Brazilian Championship

Soccer is the most popular sport in the world and moves significant amounts of money. Besides the results on the field, the search for information regarding the economic sustainability of soccer clubs is growing. Therefore, clubs must be transparent and publish their financial statements according to the established rules. Through them, it is possible to calculate the economic and financial indicators, measuring the financial situation of the entity. Thus, this research aims to analyze the main economic and financial indicators of the clubs in the South Region, participants of the series A and B of the Brazilian Championship 2022. For this, a bibliographic and documental research was carried out with a qualitative approach, in order to acquire the theoretical basis about the theme. After that, data was collected through the financial statements published by the clubs, for the years 2017 to 2021 to enable the calculation of liquidity indicators, profitability and indebtedness. The results found were organized in tables, facilitating the process of understanding and analysis. It was observed, among other things, low liquidity ratios and high dependence on third-party capital to maintain operational activity. It was also possible to note the impact of the Covid-19 pandemic on its results. Regarding the information related to the economic sustainability of the analyzed clubs it can be concluded that, although there is a small evolution of the indicators, the financial situation of the clubs is delicate and needs attention from their management and their fans.

Considerations and best practices for elite football officials return to play after COVID-19 confinement

The recent COVID-19 pandemic resulted in a total lockdown of the major football leagues, aiming to prevent the threat of an uncontrolled spread of infections, and forcing the players and match officials to home-based physical training. Differently from players, no health and physical fitness maintenance guidelines were published for match officials. Before the return to structured conditioning and officiating, match officials must perform a medical assessment, as well as systematic COVID-19 testing and detailed pulmonary function evaluation. The hygienic-sanitary prevention strategies for virus transmission must be strictly followed. In the remaining part of the present season, alterations of the game rules, namely halves of 30-40 min and no allowance for lost time, aiming to reduce the match officials physiological load may result as a safer option. Nonetheless, match officials' cognitive and physical demands, will probably be exacerbated by the increased number of substitutions per game, proposed to reduce players' match load. The proposed match scenario further stresses the importance of well-developed aerobic and anaerobic fitness in elite level match officials. Therefore, the aim of this paper was to guide a safe and successful return to play for match officials.

Prevalence and diagnostic significance of novel 12-lead ECG patterns following COVID-19 infection in elite soccer players

Background: Identification of athletes with cardiac inflammation following COVID-19 can prevent exercise fatalities. The efficacy of pre and post COVID-19 infection electrocardiograms (ECGs) for detecting athletes with myopericarditis has never been reported. We aimed to assess the prevalence and diagnostic significance of novel 12-lead ECG patterns following COVID-19 infection in elite soccer players. Method(s): We conducted a multicentre study over a 2-year period involving 5 centres and 34 clubs and compared pre COVID and post COVID ECG changes in 455 consecutive athletes. ECGs were reported in accordance with the International recommendations for ECG interpretation in athletes. The following patterns were considered abnormal if they were not detected on the pre COVID-19 infection ECG: (a) biphasic T-waves;(b) reduction in T-wave amplitude by 50% in contiguous leads;(c) ST-segment depression;(d) J-point and ST-segment elevation >0.2 mV in the precordial leads and >0.1 mV in the limb leads;(e) tall T-waves >=1.0 mV (f) low QRS-amplitude in >3 limb leads and (g) complete right bundle branch block. Athletes exhibiting novel ECG changes underwent cardiovascular magnetic resonance (CMR) scans. One club mandated CMR scans for all 28 (6%) athletes, despite the absence of cardiac symptoms or ECG changes. Result(s): Athletes were aged 22+/-5 years (89% male and 57% white). 65 (14%) athletes reported cardiac symptoms. The mean duration of illness was 3+/-4 days. The post COVID ECG was performed 14+/-16 days following a positive PCR. 440 (97%) athletes had an unchanged post COVID- 19 ECG. Of these, 3 (0.6%) had cardiac symptoms and CMRs resulted in a diagnosis of pericarditis. 15 (3%) athletes demonstrated novel ECG changes following COVID-19 infection. Among athletes who demonstrated novel ECG changes, 10 (67%) reported cardiac symptoms. 13 (87%) athletes with novel ECG changes were diagnosed with inflammatory cardiac sequelae;pericarditis (n=6), healed myocarditis (n=3), definitive myocarditis (n=2), and possible/probable myocarditis (n=2). The overall prevalence of inflammatory cardiac sequelae based on novel ECG changes was 2.8%. None of the 28 (6%) athletes, who underwent a CMR, in the absence of cardiac symptoms or novel ECG changes revealed any abnormalities. Athletes revealing novel ECG changes, had a higher prevalence of cardiac symptoms (67% v 12% p<0.0001) and longer symptom duration (8+/-8 days v 2+/-4 days;p<0.0001) compared with athletes without novel ECG changes. Among athletes without cardiac symptoms, the additional yield of novel ECG changes to detect cardiac inflammation was 20% (n=3). Conclusion(s): 3% of elite soccer players demonstrated novel ECG changes post COVID-19 infection, of which almost 90% were diagnosed with cardiac inflammation during subsequent investigation. Most athletes with novel ECG changes exhibited cardiac symptoms. Novel ECGs changes contributed to a diagnosis of cardiac inflammation in 20% of athletes without cardiac symptoms.

Trends in recreational walking trail usage in Ireland during the COVID-19 pandemic: implications for practice. (Special Issue: Covid-19 and outdoor recreation.)

Despite its potential utility for the outdoor recreation sector, there is no centralised surveillance system for recreational walking trails in Ireland and thus trail usage in Ireland during the COVID-19 pandemic is unknown. This paper aims to report trends in football count data on Irish trails during the COVID-19 period and to triangulate findings with openly available mobility data. This descriptive study analysed changes in footfall counts gathered from passive infrared sensors on 33 of Ireland's recreational walking trails between January 2019 and December 2020. The relationship between Google Community Mobility Report (GCMR) data and footfall counts was analysed to corroborate trends in footfall data. Total footfall increased by 6% between 2019 and 2020 on trails included in this analysis. Notably, mean trail usage was between 26% and 47% higher in October-December 2020 than during the same period in 2019. A strong correlation between GCMR data from 'parks' and footfall count data was found. The conclusions of this study are twofold. Firstly, the COVID-19 pandemic increased trail usage in Ireland, especially on trails closer to urban areas and there is potential for this to be a lasting legacy. Secondly, combining multiple data sources can provide trail managers with more detailed representations of trail usage and currently these are not harmonised. Future research should examine ways to encourage sustained recreational walking trail use in new users and implement novel ways to coordinate datasets across systems to monitor visitors on Irish recreational walking trails.

Return to elite football after the COVID-19 lockdown

The COVID-19 pandemic has changed the conditions for competitive football around the globe dramatically. Several competitions and leagues have been cancelled or postponed. Players have firstly been forced to training in solitude. In a second stage, players start training in small groups with strict contact restriction and return to competitive play might occur after only few weeks of normal team training preparation. These special circumstances are likely to impact football performance and injury risk in the upcoming competitions. Thus, clubs, coaching and medical staff, as well as players are challenged on the prioritization of fitness and performance, which easily can create several "catch-22-dilemmas”. The present article presents views on fitness training, physical preparation and recovery during these uncommon conditions, and how elite football players can return to the competitive field well-prepared for post-crisis football endeavours around the world. Due to the multifaceted physiological demands in elite football, the long recovery requirements after match-play and an upcoming reality with many games within a short period, elite football players, managers and clubs may face extraordinary challenges associated with return to play under the current circumstances.

Lower Quarter Y-Balance Test Anterior Reach Asymmetry and Noncontact Lower Limb Injury in Subelite Young Male Soccer Players With Different Training Experiences

Poor single-leg balance performance is associated with an increased risk of sustaining lower limb injuries in team sports. However, it is unclear whether this relationship is modified by the level of training experience (years of training experience). The objective of the present study was to evaluate whether soccer players' single-leg balance performance is related to lower limb injuries in noncontact situations with different levels of training experience. Subelite young male soccer players performed the Lower Quarter Y-Balance Test with the dominant and the nondominant leg at the beginning of the preseason. Due to COVID-19 rules, the occurrence of lower limb injuries during the second half of the competitive season was documented. The odds of injury were calculated based on a previously reported Lower Quarter Y-Balance Test cut-off score for side-to-side anterior reach difference (≥4 cm). Twelve soccer players sustained a lower leg injury in noncontact situations. Only four of them had an anterior reach difference equal to or above the cut-off score. Soccer training experience has no significant influence on the association between Lower Quarter Y-Balance Test anterior reach asymmetry and noncontact lower limb injury in young male players.

Weekly screening of youth male football players: a 14-week longitudinal investigation of interactions between groin pain and long lever adductor squeeze strength.

OBJECTIVES: To explore relationships between groin pain and adductor squeeze strength in male academy football players over a 14-week period. DESIGN: Longitudinal cohort study. METHODS: Weekly monitoring of youth male football players consisted of reporting groin pain and testing long lever adductor squeeze strength. Players who reported groin pain at any time during the study period were stratified into the "groin pain" group while players who did not report pain remained in the "no groin pain" group. Baseline squeeze strength was retrospectively compared between groups. Players that developed groin pain were examined via repeated measures ANOVA at four timepoints: baseline, last squeeze before pain, pain onset, and return to pain-free. RESULTS: 53 players were included (age 14.4 ±â€¯1.6 years). Baseline squeeze strength was not different between players in the "groin pain" (n = 29, 4.35 ±â€¯0.89 N/kg) versus "no groin pain" group (n = 24, 4.33 ±â€¯0.90 N/kg, p = 0.83). At a group level, players with no groin pain maintained similar adductor squeeze strength throughout 14 weeks (p > 0.05). Compared to baseline (4.33 ±â€¯0.90 N/kg), players with groin pain had decreased adductor squeeze strength at the last squeeze before pain (3.91 ±â€¯0.85 N/kg, p = 0.003) and at pain onset (3.58 ±â€¯0.78 N/kg, p < 0.001). Adductor squeeze strength at the point where pain subsided (4.06 ±â€¯0.95 N/kg) was not different from baseline (p = 0.14). CONCLUSIONS: Decreases in adductor squeeze strength manifest one-week prior to groin pain onset and further decrease at pain onset. Weekly adductor squeeze strength may be an early detector for groin pain in youth male football players.
