프로산하 유소년축구클럽 선수와 일반중학교 축구선수의 자기관리와 스포츠자신감 및 선수생활만족도 차이분석

The purpose of this study was to analyze the difference of self - management, self - confidence of athletes, life satisfaction of athletes between youth soccer club players under professional teams and general middle school soccer athletes. First, the interpersonal management, mental management, and training management as the sub - factors in the self - management showed higher in the youth soccer club players. It was a statistically significant difference. However there was no statistically significant difference in body management. Second, the coach leadership, physical and mental preparation, ability demonstration and social support as the sub - factors in the athletic self - confidence showed the higher level in the youth soccer players, but there was no statistically significant difference. Third, social satisfaction, athletic satisfaction, and environmental satisfaction as the sub - factors in the athletic life satisfaction were higher in youth soccer club players and statistically significant differences were also found.

Visual function of English Premier League soccer players

ABSTRACTPurpose: Examine visual function of soccer players of different skill level and playing position.Methods: Elite players from an English Premier League soccer club (n = 49) and intermediate players (n = 31) completed an assessment on a Nike SPARQ Sensory Station of: static and dynamic visual acuity, contrast sensitivity, accommodative vergence facility, target capture and perception span.Results: There was no difference between elite and intermediate players for all measures. However, competitive soccer players (elite, intermediate) did exhibit better performance in acuity-based measures of visual function and accommodative vergence compared to a population of healthy non-athletic adults (n = 230). With regards to player position, defensive players showed quicker accommodative vergence facility compared with offensive players.Conclusion: Visual function of competitive soccer players is superior to non-athletic adults, but does not differentiate the elite and intermediate player. However, defensive players do exhibit faster accommodative vergence than offensive players. We suspect that this particular visual function is advantageous for defenders given the greater demand to continually shift gaze between players located at near and far locations.

Range limitation in hip internal rotation and fifth metatarsal stress fractures (Jones fracture) in professional football players.

To identify unknown risk factors associated with fifth metatarsal stress fracture (Jones fracture). A case-controlled study was conducted among male Japanese professional football (soccer) players with (N=20) and without (N=40) a history of Jones fracture. Injury history and physical examination data were reviewed, and the two groups were compared. Univariate and multivariate logistic regression controlling for age, leg dominance and body mass index were used to obtain odds ratios (ORs) and 95% confidence intervals (CIs) to describe the association between physical examination data and the presence or absence of Jones fractures. From 2000 to 2014, among 162 professional football club players, 22 (13.6%; 21 Asians and one Caucasian) had a history of Jones fracture. Thirteen out of 22 (60%) had a Jones fracture in their non-dominant leg. The mean range of hip internal rotation (HIR) was restricted in players with a history of Jones fracture [25.9°±7.5°, mean±standard deviation (SD)] compared to those without (40.4°±11.1°, P<0.0001). Logistic regression analyses demonstrated that HIR limitation increased the risk of a Jones fracture (OR=3.03, 95% CI 1.45-6.33, P=0.003). Subgroup analysis using data prior to Jones fracture revealed a causal relationship, such that players with a restriction of HIR were at high risk of developing a Jones fracture [Crude OR (95% CI)=6.66 (1.90-23.29), P=0.003, Adjusted OR=9.91 (2.28-43.10), P=0.002]. In addition, right HIR range limitation increased the risks of developing a Jones fracture in the ipsilateral and the contralateral feet [OR=3.11 (1.35-7.16) and 2.24 (1.22-4.12), respectively]. Similarly, left HIR range limitation increased the risks in the ipsilateral or the contralateral feet [OR (95% CI)=4.88 (1.56-15.28) and 2.77 (1.08-7.08), respectively]. The restriction of HIR was associated with an increased risk of developing a Jones fracture. Since the HIR range is a modifiable factor, monitoring and improving the HIR range can lead to prevent reducing the occurrence of this fracture. III.

The relationships between rugby ground pass accuracy and kinematic variables resulting from two different pelvic orientations

Introduction: Despite having been largely understudied, one of the crucial components of a team’s success in rugby is accurate passing. This study identified biomechanical correlates of the rugby ground pass and accuracy performance.Methods: Sixteen club players (height 1.77±0.04 m; mass 86.8±16.8 kg) undertook a combined total of 96 passes and their respective body kinematics were analysed concurrent with measurements of pass accuracy at 10 m. Two distinct types of body orientations were found to be utilised by the players: a side-on orientation (pelvic rotation &gt;80 °) and a front-on orientation (pelvic rotation &lt;80 °).Results: Side-on body orientation passes were more accurate than front-on body orientation passes (p&lt;0.0001). Fair relationships were present between the pass accuracy and upper body and hip kinematics for the two distinct body orientations individually. However, no common relationships were observed between the different orientations.Conclusion: Therefore different strategies exist within players to perform the ground pass with varying grades of accuracy.

The community impact of football pitches: a case study of Maidstone United FC

The use of third-generation artificial grass pitches (AGPs) is growing in English semi-professional football. As usage grows, research into the impact of AGPs is needed, in order to examine the potential impact of such surfaces for a football club and local community. This article analyses the experiences of National League South club Maidstone United through a detailed case study. The club have installed an AGP at their stadium and are able to utilize it for up to 80 hours a week. All the club’s 45 teams are able to train and play on the AGP, and other local sport clubs have hired it, arguably increasing Public Health opportunities. This means that youth teams, first team club players and community participants alike have access to a high-quality playing surface. This has raised the club’s profile in the local community and increased income generation, supporting the financial sustainability of the club.

The impact of alcohol management practices on sports club membership and revenue.

Issue addressed: The aim of this study was to assess the impact of an alcohol management intervention on community sporting club revenue (total annual income) and membership (number of club players, teams and spectators).Methods: The study employed a cluster randomised controlled trial design that allocated clubs either an alcohol accreditation intervention or a control condition. Club representatives completed a scripted telephone survey at baseline and again ~3 years following. Demographic information about clubs was collected along with information about club income.Results: Number of players and senior teams were not significantly different between treatment groups following the intervention. The intervention group, however, showed a significantly higher mean number of spectators. Estimates of annual club income between groups at follow-up showed no significant difference in revenue.Conclusions: This study found no evidence to suggest that efforts to reduce alcohol-related harm in community sporting clubs will compromise club revenue and membership.So what?: These findings suggest that implementation of an intervention to improve alcohol management of sporting clubs may not have the unintended consequence of harming club viability.

Comparison of Speed, Agility, Anaerobic Strength and Anthropometric Characteristics in Male Football and Futsal Players

The purpose of this study is to compare speed, agility, anaerobic strength and some anthropometric characteristics in male football and futsal players. The sample of the study is composed of male futsal team players of Aydin Adnan Menderes University (19-24 aged) (n=12) and Aydin Merkez Yenikoy Football Club players (19-24 aged) (n=12). Within the scope of the study, the following techniques were applied: 30-meter speed test for determining speeds of the players, Illinois agility test for determining agility of the players, Sargent jump test for determining anaerobic strengths of the players, height weight measurement and body-mass index (B.M.I) for determining anthropometric characteristics of the players. The players were informed of the test protocols before the tests and they were voluntary for attending the study. The players attending the research did not experience any injury problem for the last 8 months and none of the players experienced any injury problem during the tests. Statistical analysis of the tests was conducted by using independent sample t-test in SPSS 20.00 program. After the tests, it was found that there was a significant difference in favor of futsal players in speeds of male futsal and football players and there was a significant difference in favor of football player in anaerobic strengths (p 0,05). As a result, there was significant difference among values regarding speed, anaerobic strength and anthropometric characteristics of male futsal and football players while there was not a significant difference in agility values.

Competition and Cooperation in European Professional Club Football

Abstract The aim of the article is to highlight the theoretical assumption that the relative competitive disadvantage between markets with different maximum sizes can be partially counteracted with strategic thinking and business-like operations. The research question presented in this article is whether there are any management tools available for clubs which they can use to improve their business competitiveness above and beyond the limitations of their maximum market size. According to the research hypothesis, there is such a tool available for clubs: the management and operation of a football club in a well-organized and business-like manner. The method of analysis is the so-called Grounded Theory (Glaser, &amp; Strauss, 1967; Locke, 2001), which is an abstract analytical schema with a systematic data analysis process. The data collection incorporates desk research, comparative analysis, organizational review, and in-depth interviews. The results are presented according to the following dimensions: a) relevance of the research question; b) specification of groups of relevant management tools; c) the role of the national football association in the process of market development; d) the role of the owners in this process; and e) how the structure of the sector and its operating processes can guarantee the efficient utilization of all the material resources which have been plowed into the sector over the last four to five years. According to the conclusions, the creation of an operating system and club model that allows for the utilization of resources - maximized market revenues and governmental sources - in the most effective way is an unavoidable challenge. The formation of the sustainable operations of clubs is fundamentally influenced by club owners. An inspection of the interaction between club owners, head coaches, and players is a key task in the process of creating a new club model.

The incidence of injuries and exposure time of professional football club players in the Premier Soccer League during football season

Background. Data on the incidence of football injuries and exposure time of players during matches and training in the South African (SA) Premier Soccer League (PSL) are lacking. Objective. To calculate the incidence of injuries and the exposure time (practice and match) of the players of a PSL team over a full season. Methods. Injury and training data of the players in the squad (N=32) were recorded on a daily basis by the medical support staff, according to the methods of the Football Medical Assessment and Research Centre (F-MARC) protocol. Results. One hundred and thirty injuries were recorded in the season. The most affected body parts were the thigh (n=27, 21%) and ankle (n=27, 21%). The overall incidence was 13.4 injuries per 1 000 player-hours. The incidence during training was 6.6 injuries/1 000 playerhours and during matches 88.9 injuries/1 000 player-hours. The most frequent injury was haematoma/contusion/bruising (n=43, 33%). Of the total injuries, 12% were recurrent. Injury through contact with another player was high (62%). Seventy-six per cent of the injuries were not associated with any violation of the laws of the game. The average time off due to injury was 8 days. The total exposure time over the full season resulted in a combined average of 18 162 minutes (~303 hours). Conclusion. These data differ from the data in European studies. Injury and exposure data measured throughout the season have the potential to identify risks and mechanisms of injuries. This study highlights the necessity for all clubs in the PSL to adopt a standardised injury monitoring programme, using standardised methodology, so that the management of professional players in SA may be improved.

Methods: Sixteen club players (height 1.77±0.04 m; mass 86.8±16.8 kg) undertook a combined total of 96 passes and their respective body kinematics were analysed concurrent with measurements of pass accuracy at 10 m. Two distinct types of body orientations were found to be utilised by the players: a side-on orientation (pelvic rotation >80 °) and a front-on orientation (pelvic rotation <80 °). Results: Side-on body orientation passes were more accurate than front-on body orientation passes (p<0.0001). Fair relationships were present between the pass accuracy and upper body and hip kinematics for the two distinct body orientations individually. However, no common relationships were observed between the different orientations. Conclusion: Therefore different strategies exist within players to perform the ground pass with varying grades of accuracy.

What is the extent of exposure to periods of match congestion in professional soccer players?

This study investigated exposure to periods of match congestion in regular starter players in a professional soccer team across 4 competitive seasons (2009–2013). Players were divided into 2 groups: club players (club match exposure only, n = 41) and national team players (club and national team exposure, n = 22). The frequency of congested periods that players were potentially exposed to per season was initially determined: 2-match cycles – potential exposure to 2 successive matches separated by a ≤ 3-day interval calculated immediately from the end of play in match 1 to the start of play in match 2 occurred on 12.5 ± 5.1 and 16.0 ± 4.7 occasions for club and national team players, respectively. Multiple-match cycles: potential exposure to 3-, 4-, 5- or 6-matches played successively within a ≤ 4-day period commencing from the day after each match occurred on 8.5 ± 2.1, 4.3 ± 1.7, 3.0 ± 0.8 and 1.8 ± 0.5 occasions for club and 11.5 ± 2.4, 6.5 ± 0.6, 4.5 ± 1.9 and 3.0 ± 1.4 occasions for national team players, respectively. With regard to actual exposure in club and national team players, respectively, participation in both matches in 2-match cycles attained 61.2% and 59.3% while 90-min play in both matches was only completed on 38.2% and 40.5% of occasions and ≥75-min play on 47.6% and 50.0% of occasions, despite availability to play in both groups being >86%. While availability to play in all players was frequently >70% for multiple-match cycles, a trend was observed for a sharp decline in participation as the number of matches in the cycles increased. Therefore, the present players were not extensively exposed to periods of fixture congestion.

The ‘club versus country’ debate: investigating English fan loyalty toward club and national teams

The ‘club versus country’ debate, which refers to an individual’s allegiance to their respective club and national teams, has become an increasingly popular topic for debate in the context of English football. Whilst prior work in this area has focused on the tensions between club officials and national associations, this study investigated the attitudinal and behavioural loyalty of fans towards club and national teams. Data were collected from 647 football fans across 16 English club teams utilizing a survey approach. Findings suggest that those with high levels of loyalty to their club are more likely to be loyal to the national team, questioning whether this is a ‘versus’ debate at all from the fan perspective. In addition, Premier League fans display lower levels of attitudinal loyalty to the national team than lower league fans, which may reflect underlying concerns that club players may sustain injuries in national team matches.

A retrospective study on anthropometrical, physical fitness, and motor coordination characteristics that influence dropout, contract status, and first-team playing time in high-level soccer players aged eight to eighteen years.

The goal of this article was twofold, and a 2-study approach was conducted. The first study aimed to expose the anthropometrical, physical performance, and motor coordination characteristics that influence dropout from a high-level soccer training program in players aged 8-16 years. The mixed-longitudinal sample included 388 Belgian youth soccer players who were assigned to either a "club group" or a "dropout group." In the second study, cross-sectional data of anthropometry, physical performance, and motor coordination were retrospectively explored to investigate which characteristics influence future contract status (contract vs. no contract group) and first-team playing time for 72 high-level youth soccer players (mean age = 16.2 years). Generally, club players outperformed their dropout peers for motor coordination, soccer-specific aerobic endurance, and speed. Anthropometry and estimated maturity status did not discriminate between club and dropout players. Contract players jumped further (p = 0.011) and had faster times for a 5-m sprint (p = 0.041) than no contract players. The following prediction equation explains 16.7% of the variance in future playing minutes in adolescent youth male soccer players: -2,869.3 + 14.6 × standing broad jump. Practitioners should include the evaluation of motor coordination, aerobic endurance, and speed performances to distinguish high-level soccer players further succeeding a talent development program and future dropout players, between 8 and 16 years. From the age of 16 years, measures of explosivity are supportive when selecting players into a future professional soccer career.

Concussion in rugby: knowledge and attitudes of players.

Concussion is a traumatic brain injury, resulting in the alteration of mental status with or without loss of consciousness. There is increasing awareness that recurrent concussion may contribute to long-term neurological complication. To determine player knowledge and attitudes regarding concussion. To identify sources of information and medical care, and to estimate the incidence of concussion in this group. To determine if player gender and grade of competition are associated with differences in knowledge, attitudes, medical care, and incidence. Five rugby teams were recruited and players invited to complete a paper-based questionnaire. The questionnaire sought information on player demographics, knowledge level, attitudes and concussion experience. 90.8% of players knew they should not continue playing when concussed. 75% of players would continue an important game even if concussed. Of those concussed, 39.1% have tried to influence medical assessment with 78.2% stating it is possible or quite easy to do so. Males are less likely to worry about long-term effects of concussion (χ (2)=9.23, p=0.026). Club players are less likely to have medical care at training (χ (2)=28.2, p<0.001) or matches (χ (2)=19.47 p<0.001). Despite good knowledge of concussion complications, management players engage in unsafe behaviour with little difference between gender and competition grades. Information regarding symptoms and management should be available to all players, coaches, and parents. Provision of medical care should be mandatory at every level of competition.

A snapshot of chronic ankle instability in a cohort of netball players.

Ankle injuries account for the highest percentage of injuries in netball, yet the chronic nature of ankle sprains is under reported within this population group. Chronic ankle instability is a term used to describe certain insufficiencies that persist after an acute ankle sprain. The aim of this study was to investigate recurrent sprain, perceived ankle instability and mechanical ankle instability in a cohort of netball players. Cross-sectional study. Ninety-six female netball players (24.1±7.9 years) were recruited (42 club players and 54 inter-district players). Recurrent sprain was defined as two or more lifetime sprains to the same ankle. Perceived ankle instability was quantified with the Cumberland Ankle Instability Tool - Youth. Mechanical ankle instability was quantified via inversion-eversion rotations using an ankle arthrometer at torques of 3Nm. Forty-seven percent of the cohort had recurrently sprained an ankle. Of the 69 players with a previously sprained ankle, 64% had a moderate-severe degree of perceived ankle instability. The total inversion-eversion angle was 31.1±8.7 degrees. Club players had more cases of moderate-severe perceived ankle instability (p=0.01) and larger inversion-eversion angles (p=0.001) compared to inter-district players. Recurrent ankle sprain and perceived ankle instability are easily identifiable aspects of chronic ankle instability shown to be prevalent within this cohort. Additional research is required to quantify a cut-off value for mechanical instability. Club netball players were found to have more counts of moderate-severe perceived ankle instability and larger inversion-eversion angles when compared to the inter-district netball players.

The Effect of Ball Carrying on the Sprinting Speed of International Rugby Union Players

Speed is considered to be a highly valuable ability in rugby union. One unique aspect of rugby is that players need to be effective at sprinting while carrying a rugby ball. Previous research reported that amateur club players were slower while sprinting with the ball, than without. The purpose of the current research was to examine how sprinting while carrying a ball affected the sprinting speed of international rugby players. Twenty-six international players performed 6 × 40 m sprints under three conditions: Ball One Hand (B1H), Ball Two Hands (B2H) and No Ball (NB). Timing gates were placed at the 0 m, 10 m, 30 m and the 40m mark of the sprint. The 0–10m was used to examine initial acceleration; 30–40 m was used to examine maximal velocity and the 10–30 m section to analyze the acceleration up to maximal velocity. Comparisons were also made between backs and forwards. Backs were found to be faster than forwards at each of the splits for the NB, B1H and B2H conditions (0.04 – 0.08 s, p&lt;0.0001 – p=0.015, d=0.88 – 1.35). The results of the study showed only trivial and small differences (1–2%) between the B1H and B2H conditions with the NB condition. The decrements in speed from the B2H conditions were much less for the international players when compared with previously reported data from amateur club players. Coaches working with rugby players should regularly incorporate sessions focused on speed development, as well as including B1H and B2H as part of a speed testing battery.

Éléments de redéfinition du basket francilien au prisme du « hip-hop ball »

Basketball in Île de France has evolved since the spread of American basketball-hip-hop (‘hip-hop ball’) culture in France in the 2000s. The boundary between street players and club players is increasingly blurred, as they have changed the way they play and their representation of practice as a result of coming into contact with the culture of American basketball. The article seeks to demonstrate that it is useful to go beyond the traditional classification based on the ‘spatio-ludic’ criterion (street/club) to redefine and understand basketball players in the Paris region. Taking an analysis approach with regard to the close relationship players have with hip-hop ball culture, the authors wish to propose another way of interpreting basketball in Île de France. This will highlight the effects of the influence of American basketball on basketball in Île de France and the sociocultural and identity considerations arising from them.
