Relative age effect among U14 football players in Portugal: do geographical location, team quality and playing position matter?

ABSTRACT Background Relative age effect (RAE) has been found to be particularly pronounced between 13 and 15 years of age in male football. However, the extent to which the phenomenon varies within a country demands a more comprehensive approach. Purpose To examine the effects of geographical location (north; centre-north; centre-south; south; islands), team quality (top-ranked; middle-ranked; bottom-ranked) and playing position (goalkeeper; defender; midfielder; forward) on the birthdate distribution (Q1: January–March; Q2: April–June; Q3: July–September; Q4: October–December) of U14 Portuguese players selected for the national inter-association tournament Lopes da Silva. Methods A total of 2,693 players (mean age: 14.12 ± 0.38 years), selected by the 22 regional football associations for the last seven editions of the tournament (2013–2019), was included in the sample. Results Chi-square analysis showed a small-to-medium RAE in the U14 cohort compared to the general Portuguese male population (p < .01). Furthermore, the multinomial logistic regression model revealed that the probabilities of selecting Q1 players (vs. Q4) differed (p < .01) based on geographical location (increases of 76.3% in the north and 87.3% in the centre-north zone compared to the regional teams from islands) and team quality (increase of 94.6% in top-ranked compared to the bottom-ranked teams). The playing position did not affect the magnitude of RAE. Conclusion Our findings confirm that besides being present in U14 Portuguese male football, the magnitude of RAE is influenced by demographic factors. This study also supports the notion that coaching staffs tend to choose players based on attributes associated with chronological age, seeking to achieve short-term competitive outcomes.

Exploring offensive players’ collective movements and positioning dynamics in high-performance padel matches using tracking technology

ABSTRACT Racket sports such as padel are characterised by a variety of specific displacements and behaviours on the court with the aim to cover spaces and take an offensive advantage during the point. The aim of this study was to analyse players’ location in offensive position when opponent hits the ball in different defensive zones. The sample included nine matches from a total of three top national indoor padel tournaments. Twenty-four male padel players performed the matches. Players and ball position was registered using a computerised motion tracking video system. Results showed a significant relation between offensive players’ movements (forward, backward or sideways) according to the position of the ball in defensive zones. Heat map and statistics analysis showed that regarding players’ width positioning, when the ball is in one corner of the defensive zone, both offensive players move to that side of the court. However, regarding players’ depth positioning, if one offensive player moves close to the net, his partner moves some metres back. Such knowledge may constitute a very important factor affecting tactic and task design for padel players and coaches and could be used as an important reference for others ball-over-net sports such as doubles tennis, doubles badminton, beach tennis or volleyball.

Karate-do Athletes' Reactions to Aggression and Motivation during Fit and Well Zone Tournament Performance

This descriptive-type study assessed the profile of the respondents along; age, gender, length of training, highest level of participation in fighting karate-do games. More so, looking into the level of aggression and level of motivation as factors that influence the participants in karate-do tournaments in the city of Cagayan de Oro. The data were gathered using questionnaire and observation, and were treated using frequency count, and t-ratio for r. Correlation among the variables was determined, as well as the capabilities of aggression and motivation of the respondents. It was found out that the respondents were withing the age of 18 – 21 years old, and majority were male. It also revealed their length of training to be 1-5 years while their highest level of participation in the game was in the National tournament. The participants level of aggression and motivation was very high aggressive and highly motivated. It was concluded that while the participants in karate-do tournaments fight in national tournaments, their capability still needs to be enhanced and support by various organizations that are involved.

Motivation and Mental Toughness among Table Tennis Athletes: Achievement in Sports Performance

This descriptive-type study assessed the motivation and mental toughness among table tennis athletes and their achievements in sports performance. The respondents of this study were 68 table tennis varsity athletes who officially played in the singles event during the Mindanao Association of State and Tertiary Schools (MASTS) Friendship Games in Tandag, Surigao Del Sur. The data were gathered using questionnaires and observation and were treated using frequency and percentage to measure the significant relationship between and among the variables. In addition, the Pearson Product Moment Correlation of Coefficient or Pearson r was utilized. It was concluded that schools, universities, and college administrators must give adequate support and provide ample budgetary needs for the varsity athletes to participate in local, regional, and national competitions and tournaments. Government and institutions should equip, train, and manage competitive stress among athletes and enhance their mental capacity to handle performance during games. The researchers concluded that institutions must also consider younger players in their selection process of the varsity. Based on the result of the study, more immature players were more motivated and highly mentally tough compared to the older players.

Injury rate in professional football: A systematic review

The goal of this paper is to determine the injury frequency rate in professional football players in leagues and national competitions by analyzing existing papers. We have chosen 21 articles according to the PRISMA method from the Google Scholar, ResearchGate Scopus, and Web of Science databases that fit both inclusion and exclusion criteria. We have discussed the following four segments based on the content of the selected papers: 1) An analysis of the injury frequency rate on the level of national teams, 2) An analysis of the injury frequency rate in club leagues, 3) A comparison of the injury frequency rate in matches and in practice, and 4) An analysis of the injury frequency rate in male versus female football players. The paper concludes that major national team tournaments have the highest injury frequency rate and that the probability of injury is four to five times higher in a match than in practice. The injury frequency rate in female players is lower than in male players regardless of the type of competition (national teams or leagues).

The Relationshıp Between Injury Anxiety and Forgiveness Flexıbility: A Research for Elite Field Hockey Athletes

Purpose: This study aims to examine the relationship between injury anxiety and forgiveness flexibility levels of elite field hockey players. Injury anxiety and forgiveness flexibility levels were compared in terms of gender, the status of being a national athlete, injury history, and frequency of training. Method: In line with the purpose of the research, it is descriptive research in which the relational survey model, one of the quantitative research methods, is used. With this method, it is used to grasp and explain the relationship between various variables without any attempt to change the current situation. In this framework, a research model was created that aims to determine the existence of covariance between two or more variables. The research population consists of field hockey players. The population of the study is elite field hockey players who participated in national or international field hockey tournaments. The research sample consists of 161 participants (66 Female, 41%; 95% Male, 59%) selected by convenience sampling method, which is one of the non-random sampling methods. The “Sports Injury Anxiety” scale was used to determine the injury anxiety levels of field hockey players who participated in the study voluntarily. The “Forgiveness Flexibility Scale” was used to determine the levels of forgiveness flexibility, and the “Personal Information Form” prepared by the researchers was used to collect information about demographic characteristics (gender, status of being a national athlete, injury history, training frequency). Conclusion: It was determined that there was a significant difference in injury anxiety and forgiveness flexibility scores of elite field hockey players according to gender and training frequency variables. On the other hand, while there was a significant difference in injury anxiety scores according to the status of being a national athlete and having an injury, no significant difference was found in the mean scores of forgiveness flexibility. As a result of the analysis performed to determine the relationship between injury anxiety and forgiveness flexibility, a positive and significant relationship was determined between the injury anxiety and forgiveness flexibility levels of the athletes. Finally, it was concluded that training frequency is an important predictor of injury anxiety, and as the training frequency increases, the athlete's injury anxiety level decreases. Keywords: Field hockey, injury anxiety, forgiveness flexibility

Epidemiology and pain in elementary school-aged players: a survey of Japanese badminton players participating in the national tournament

Pain is common in athletes which should be well managed. To identify risk factors for shoulder pain, and the association between shoulder pain, lower back pain and knee pain among elementary school-aged badminton players, we conducted a cross-sectional study to collect data of the past year among 611 elementary school age (7–12 years old) badminton players belonging to the Japan Schoolchildren Badminton Federation using a questionnaire. Odds ratio (OR) and 95% confidence interval (CI) were estimated by multivariate logistic regression analysis. The overall incidence rate of shoulder injuries, lower back injuries and knee injuries was 0.38 injuries per 1000 h of badminton training. Players with training time per day > 2.5 h were 2.64 times (95% CI 1.03–6.78, p = 0.043) more likely to sustain shoulder pain than those with training time per day ≤ 2.5 h. A significant association was revealed between shoulder pain and knee pain as well as between lower back pain and knee pain as training hours per day > 2.5 h. Moreover, lower back pain was significantly associated with shoulder pain independent of training hours per day (≤ 2.5 h: p = 0.001; > 2.5 h: p < 0.001). These findings indicate that training time per day is risk factor, and shoulder pain, lower back pain and knee pain were associated with each other in elementary school-aged badminton players.

Composición corporal y somatotipo del equipo de gimnasia rítmica, Tricampeón del torneo nacional universitario FENAUDE Chile

The objective of this study was to determine the body composition and somatotype of the rhythmic gymnastics team, three-time champion of the national university tournament FENAUDE Chile. To achieve this objective, anthropometric measurements were taken to the 9 athletes who participated in the university tournament, who were between 22.17 ± 1.91 years old. It was evaluated using the marking and measurement protocol of the International Society for the Advancement in Kine anthropometric (ISAK), and the Deborah Kerr Body Composition and Heath-Carter Somatotype methods were applied. For the statistical analysis, the statistical package IBM SPSS V.24 was used and additionally, to generate the graph of the somatochart, a spreadsheet created in the Microsoft Excel program was used. Height of 159.00 ± 6.19 cm was determined, Sitting Height 33.38 ± 1.48, Weight 56.98 ± 8.96kg, in addition to the predominant somatotype for the group of athletes studied is the Endomorph-Mesomorph (3, 88-3.60-1.78) and body composition, the mean values were: Mg = 30.42%, Mm = 47.12%; Mr = 4.28% Mo = 11.68% and Mp = 6.51.

Rethinking extra-time in major national football tournaments

Extra-time (ET) of 30 minutes is played if football match scores are level after 90 minutes in tournament knockout play. The demanding schedule of these tournaments along with possible ET matches in the knockout stages significantly increase players’ overload and injury risk. Present study aimed to determine whether ET during major football national team tournaments contributes to the game outcome. Data on the percentage of elimination matches that needed ET, and the percentage of ET matches that eventually required shootouts were retrieved. Over the years, increased number of participating teams lead to increased number of knockout games, and more knockout games needed ET (13% until 1978, 33% from 1982, in FIFA World Cup). In a significant percentage of matches, the ET itself did not determine the winning team, and the majority of ET matches winners were determined by shootouts (FIFA World Cup since 1982: 60.8%; UEFA European championship: 61.3%; Copa America: 92%). The purpose of playing ET is to make a fair game outcome, and not leave the winning decision for shootouts. However, since in most matches ET does not determine the winner, while significantly increasing the player’s overload and injury susceptibility, the need for ET mandates rethinking.

Competition Experience, Relative Age Effect and Average Age of the Senior World Events’ Medal-Winning Basketball Players

"The International Basketball Federation (FIBA) has changed its youth competition system in 2004, and due to this regulation, many players had the chance to compete every year at youth level and later, to elevate to the top. The purpose of our study was to inspect those medal-winning European basketball players who competed in the past 19 senior basketball world events. We analysed the tendencies of selection by dissecting the set-up of successful senior national teams. We investigated each one of the 281 European basketball players who won a medal during the analysed period (2000-2019). We collected data from the archive page of FIBA. Our goal was to see whether there was a relation between the youth competition experience and the minutes spent in senior world events. We used the Cramer Association Coefficient, Relative Age Effect and average age were also inspected. We found that participation in the national youth tournaments is important but not the most exclusive factor of selection. There are opportunities for success in the adult national teams for players who have covered alternative sports careers – the factor of national youth experience is not exclusive. We suppose that head coaches utilize older and more experienced players on the Olympic Games, the average ages of successful Olympic medal-winner teams are higher than other world events’ medallists. Despite the fact that we were not able to find statistically proven and associative relationship between national youth recruitment eligibility and the minutes in game spent by successful adult players, further research could be gap fillers in exploring key factors in adulthood efficiency. Keywords: talent selection, competition experience, FIBA, basketball players, sport career."

The Relationship between Motivational Climate and Personal Treatment Satisfaction among Young Soccer Players in Norway: The Moderating Role of Supportive Coach-Behaviour.

Motivational climate and coach-behaviour seem important to understand sport involvement and participation. However, less is known about the potential interaction between these facets, and how it relates to athlete satisfaction. This study’s purpose is to examine the relationship between the perceived motivational climate, supportive coach-behaviour, and athletes’ personal treatment satisfaction among young soccer players. More specifically, we investigated the moderating effect of supportive coach-behaviour on the relationship between motivational climate and personal treatment satisfaction. Five hundred and thirty-two players (Mean age = 15.4 years, SD = 1.2) attending a Norwegian national soccer tournament participated in the study. Self-completion questionnaires were used to attain data. A linear regression analysis revealed that mastery of climate and supportive coach-behaviour were positively associated with personal treatment satisfaction. A negative association was found between performance climate and personal treatment satisfaction. Further, moderation analyses revealed that supportive coach-behaviour moderated the relationship between performance climate and personal treatment satisfaction. The findings indicate that a performance climate may not be as maladaptive when coaches provide supportive behaviour. The findings highlight the value of a further examination of the interaction between motivational climate and coaching behaviours, and its potential relations to young athlete’s sport experience.

Statistical Analysis of Basketball Teams Through Normal Distribution and R Programming

Basketball has existed for almost 130 years, becoming one of the most famous sports worldwide by affecting millions of lives and having national and global tournaments. With the general improvement of people's concern and love for sports competition, sports analytics’ role will become more prominent. Hence, this paper combines the relevant knowledge of statistics and typical basketball competition cases from NBA, expounding the application of statistics in sports competition. The paper first examines the importance of normal distribution (also called Gaussian distribution) in statistics through its probability density function and the function's graph. The function has two parameters: the mean for the maximum and standard deviation for the distance away from the mean[1]. By compiling datasets of past teams and individuals for their basketball performances and making simple calculations of their standard deviation and mean, the paper constructs normal distribution graphs using the R programming language. Finally, the paper examines the Real Plus-Minus value and its importance in basketball.

The role of alcohol in the link between national football (soccer) tournaments and domestic abuse - Evidence from England.

Domestic abuse is increasingly recognised as a serious public health concern worldwide. Previous research has suggested a link between national football (soccer) tournaments and domestic abuse. While hypothesized to be a significant factor, the role alcohol plays in this relationship has not yet been explored quantitatively. In this study, using 10 years' worth of crime data (from 2010 to 2019) from the second largest police force in England (West Midlands Police), we explored the effect of England draws, losses, and wins in national football tournaments on the number of alcohol and non-alcohol-related domestic abuse cases reported to the police. Results from a series of negative binomial regression analyses show that the number of reported alcohol-related domestic abuse cases increases by 47%, 95% confidence interval [26%-71%], following an England football victory. This effect is limited to alcohol-related cases. The estimate translates into a 0.53, 95% CI [0.3-0.8], increase in the daily rate of alcohol-related cases per 100,000 individuals. The England win effect survives various robustness checks (including the re-analysis of a dataset from another geographical area in England), and its time course is strongly consistent with a causal link between England's football victories and an increase in alcohol-related domestic abuse. We also found a comparable increase in the number of other (not classified as domestic abuse) alcohol-related violent crimes on England win days. Further research is required to understand the exact causal pathway between national football tournaments, alcohol consumption, and violent behaviours in domestic settings.

Injury prevention effects of stretching exercise intervention by physical therapists in male high school soccer players.

We aimed to examine the prevalence of injury after physical therapy intervention for muscle tightness and injury prevention in male high school soccer players. A randomized controlled trial was conducted. Participants comprised 124 players from two high schools who competed in national tournament soccer games held from April 2018 to March 2019. Players were randomly divided into intervention (with a 12-week stretching intervention by physical therapists) and control groups (without the intervention). Players and coaches provided written information regarding injuries and daily training and match times; physical therapists visited each team weekly to collect data and review documentation. Muscle tightness and injury incidence, number, type, location, circumstances, situations, severity, and contents during the 12-week intervention period and a subsequent 40-week observation period were compared between groups. Injuries were significantly lower with intervention during the 40-week observation period (P<.01) but not during the 12-week intervention period (P=.44). Injury types mainly included disorder, non-contact, lower-limb/trunk, and muscle/tendon injuries. Significant interactions were observed for all tightness-test measurement items. The intervention group showed significant improvements in heel-buttock distance, and straight leg-raise and hip rotation angles (pre-intervention<12weeks<52weeks), as well as significant improvements in ankle dorsiflexion angles at 12 and 52weeks (relative to pre-intervention values). Instructed stretching exercises, personally designed by physical therapists to address muscle tightness, improved the range of motion and trunk flexibility, with a positive effect on the injury rate in male high school soccer players, especially for non-contact disorder injuries during training.

NEUROMUSCULAR FATIGUE ASSESMENT IN HAMSTRING MUSCLES IN ELITE ULTIMATE FRISBEE PLAYERS

Ultimate Frisbee (UF) is a new team-sport, with more than 1.5 million practitioners worldwide. It is characterized by changes of direction, accelerations / decelerations, jumps and landings. It has been found that the incidence and prevalence of lower body injuries is 68% of total injuries and 73% are hamstring injuries. PURPOSE: To determine hamstring neuromuscular fatigue in UF players. METHODS: A descriptive observational study with analytical component was performed in 18 elite male UF players (age: 26 ± 5 years, weight: 67.5 ± 7kg, height: 1.73 ± 0.05m, BMI: 22 +/- 2), who participated and won the Colombian Interclubes National Tournament 2019. The strength of the hamstrings was evaluated using force platforms with isometric hamstring test, each player performed a maximum isometric contraction in supine position, 90° hip flexion and knee of the analyzed leg. The athlete exerts maximum force with the heel on the force platform for 3 seconds. 3 attempts were made with each leg with 30 seconds rest between each attempt, at the start of the tournament and at the end of the tournament. The athletes played 8 90-minute matches during 4 days of competition. A statistical analysis was performed using the student T test and the Wilcoxon test. RESULTS: Significant differences were found between the pre and post-tournament evaluation in the variables of peak vertical force of the right leg (314 ± 51.5 vs 256 ± 38.5 N p = <0.001), compared with the peak vertical force of the left leg (272 ±43.5 vs 246 ± 46.6 N p = 0.4) that had a non statistically significant change. It was also found that the force in the right leg had significant differences at 100 ms (113 ± 37.6 vs 95 ±40.1 p = 0.02) 150 ms (165 ± 52.8 vs 133 ± 53.9 p = 0.002) and 200 ms (200 ± 57.3 vs 167 ± 57.5 p = 0.0004). CONCLUSIONS: The decrease found in hamstring peak vertical force corresponds to the fatigue that athletes present and accumulate during the tournament and predispose to be a risk factor for hamstring and anterior cruciate ligament injury due to changes in direction and unipodal landings. They are frequent in this sport. Likewise, the predisposition of the right leg as the dominant leg increases the incidence of injuries in the knee joint compromising dynamic stability

THE EFFECTS OF RECOVERY TECHNIQUES TAUGHT TO CHILDREN AFTER TRAUMA EXPERIENCE ON THE COPING STRATEGIES

Through selecting and applying 24 professional physical development exercises for male students of Vovinam Club at FPT University Ho Chi Minh City (HCMC) for 6 month-period, the results showed that students' professional fitness who participated in the experimental group had a remarkable growth compared to the students participated in the control group. Specifically, the average of all 7 evaluation criteria had a statistically significant difference at probability threshold P <0.001. At the same time, through the results at the national student Vovinam tournament in 2019 (took place in Thua Thien Hue), 5 of 20 students participated in this experimental group, achieved excellent results with 5 medals of all kinds (include of 01 gold medal, 01 silver medal, 03 bronze medals). Thereby, it has contributed significantly to help FPT University HCMC rise to the rank second of Vietnam). This is an encouraging first step so that we are motivated to continue implementing new works to apply this research result into practice. Article visualizations:

Treatment of open ankle dislocation without associated fractures in a young athlete using external fixation and ligament repair with suture tape augmentation

BackgroundAnkle dislocation without fracture is an extremely rare injury because it is usually accompanied by concomitant malleolar fractures from the anatomical and mechanical viewpoints.Case presentationWe report the case of a 17-year-old woman who was injured while playing basketball. Her ankle was swollen and deformed. Plain X-ray revealed tibiotalar dislocation in the medial direction without any fractures.Immediate reduction and ligament repair using suture tape augmentation were performed.ConclusionsAt 5 months postoperatively, the patient returned to playing basketball without any complaints. After an additional 2 months, the patient participated and played in the Winter Cup 2019 (the national high school basketball tournament in Japan) at the previous performance level.

The Role of Alcohol in the Link Between National Football Tournaments (Soccer) and Domestic Abuse – Evidence From England

Domestic abuse is increasingly recognized as a serious public health concern worldwide. Previous research has suggested a link between national football (soccer) tournaments and domestic abuse. While hypothesized to be a significant factor, the role alcohol plays in this relationship has not yet been explored quantitatively. In this study, using 10 years’ worth of crime data (from 2010 to 2019) from the third largest police force in England (West Midlands police), we explored the effect of England draws, losses, and wins in national football tournaments on the number of alcohol and non-alcohol-related domestic abuse cases reported to the police. Results from a series of negative binomial regression analyses show that the number of reported alcohol-related domestic abuse cases increases by 47%, 95% confidence interval [26% – 71%], following an England football victory. This effect is limited to alcohol-related cases. The estimate translates into a 0.53, 95% CI [0.3 – 0.8], increase in the daily rate of alcohol-related cases per 100,000 individuals. The England win effect survives various robustness checks (including the re-analysis of a data set from another geographical area in England), and its time course is strongly consistent with a causal link between England’s football victories and an increase in alcohol-related domestic abuse. We also found a comparable increase in the number of other (non-domestic abuse related) alcohol-related violent crimes on England win days. Further research is required to understand the exact causal pathway between national football tournaments, alcohol consumption, and violent behaviors in domestic settings.
