A Predominant Physical Component Profile of Persipura Junior Football Athletes

This study was aimed at determining the description of predominant physical component profile (physical fitness, fat thickness, agility, muscle endurance, flexibility, power, muscle strength and balance) of the Persipura Junior Football Athletes. This study used a survey of PERSIPURA Junior Football athletes involving 39 people. The inclusions of the athletes inculde male gender, aged 21 years, height 177 cm, an ideal body weight, a healthy body, and moderate to good categories of physical fitness. The instrument used in this study were dynamometer for muscle strength; crunches for muscular endurance, push-ups, squat jumps, beam side step for agility, flexometer for flexibility, vertical jump for power, and 2.4 km running test for physical fitness. The results showed that the Persipura Junior Football athletes had a good physical fitness, less triceps fat thickness, a normal sub scapular thickness, a normal supra iliaca thickness, lack of agility, a good endurance of arm and shoulder muscles, a good endurance of abdominal muscles, an adequate flexibility, a perfect vertical jump muscle power, a good medicine ball muscle explosive power, a good full muscle strength, lack push muscle strength, and a very good balance. It concludes that to gain an optimal predominant physical component, sports science with measurable and well-programmed exercises should be applied, so that the physical component of triceps fat thickness, agility, and push muscle strength could increase.

Thought processes during set shot goalkicking in Australian Rules football: An analysis of youth and semi-professional footballers using Think Aloud

At present, there has been little attention given to exploring the cognitive processes of athletes in Australian Rules football during self-paced tasks such as the set shot goal kick attempt. Therefore, this study used a Think Aloud (TA) protocol analysis to explore the cognitions of Junior and Adult footballers undertaking the performance of a set shot goal kicking attempt in naturalistic conditions. This involved 64 male Australian Rules footballers, comprising 37 elite-level senior (adult) players (M age = 23.3 years) and 27 elite-level junior (M age = 14.6 years) players. Player's verbalisations were recorded during each performance of the goal kicking task, transcribed verbatim, and deductively and inductively analysed. The analyses revealed that planning, gathering information and description of outcome were the main three verbalised themes overall among junior and adult footballers. The analyses also indicated that as task difficulty increases, athlete cognitions relating to self-doubt increases and pre-performance routines decreases. In contrast to Adults, our results indicate that Junior footballers gather more information when undertaking close range set shot goal kicking attempts and also verbalise more diagnostic outcomes and comments relating to self-doubt when undertaking long range set shot goal kicking attempts. Adult footballers were also found to verbalise more reactive comments across all kick distances and verbalise more thoughts relating to mental readiness and pre-performance routine from close range compared long range distances. These findings have implications for the acquisition of skill in sport and draw on key perspectives from Dynamic Systems Theory to advance understanding of the cognitive processes underpinning set shot goal kicking performance in Australian Rules football.

The three and six-substitution rules in football: A preliminary comparative analysis in quantitative replacing, game statistics, win rate and winning probability

Abstract Aims: The present study aimed to analyze the effects of the 3- and 6-substitution rule and qualification round on substitution pattern, game statistics, win rate, and winning probability in Brazil's largest U-20 football tournament. Methods: We analyzed 1,339 matches from the Sao Paulo Junior Football Cup implementing a before-after design considering 6 years (three seasons for 3-subs and three for 6-subs). Results: Approximately 31% of teams used the total number of replacements of 6-subs with the same substitution pattern between rounds. The win rate for both substitution rules was approximately 79% (OR = 3.10, 95%CI [2.18, 4.51]) with a small reduced magnitude (approximately 5%) in 6-subs knockout games. Logistic regression analysis showed that the 6-subs regulation tournament predicted a reduced probability (-12%) of a match ending with a win in the knockout round. There were 6-subs knockout effects (p < 0.05) on game statistics with “negligible” effect size (ES) on “effective playing time” (+1 min; ES = 0.15); decreased “goal scoring” (-0.3;ES = 0.09) and “red cards” per match (-0.1; ES = 0.06). An ordered probit model and partial effects showed that including a replacement unit on a team increased the winning probability by 8% in the group stage, and reduced the chance (-4%) for the opponents trying to do the same in the knockout stage. Conclusion: Overall, 6-subs caused minor effects on the game statistics, win rate, and winning probability. Understanding substitution strategies and motivation, individual and collective performance effects, and whether there will be changes in the game profile will become relevant research issues when a greater number of substitutions rules are universally instituted.

Effects of Linear Versus Changes of Direction Repeated Sprints on Intermittent High Intensity Running Performance in High-level Junior Football Players over an Entire Season: A Randomized Trial.

Background: Changes of direction (COD) repeated sprints (RSs) might have greater relevance to football than linear RSs. We aimed to compare the effects of linear and COD RSs on intermittent high intensity running (HIR) over an entire season. Methods: In total, 19 high-level male football players (16–19 years) randomly performed linear RSs or COD RSs twice a week during their competitive season over 22 weeks. Yo-Yo intermittent recovery test level 2 (Yo-Yo IR2), and 10- and 20-m sprint was assessed pre-, mid- (11 weeks), and post-intervention (22 weeks). Maximal oxygen uptake (VO2max) was assessed pre- and post-intervention. Results: There was no interaction effect (time x group) in Yo-Yo IR2 (p = 0.36, pη2 = 0.06) or sprint tests (10 m: p = 0.55, pη2 = 0.04, 20 m: p = 0.28 pη2 = 0.08), and no change differences between groups. There was a main effect of time for Yo-Yo IR2 (p = 0.002, pη2 = 0.31) but not in sprints or VO2max. Conclusion: Linear and COD RS exercise twice a week over 22 weeks equally improves intermittent HIR performance but does not improve sprint time or aerobic power in high-level junior football players. However, due to our two-armed intervention, we cannot exclude possible effects from other exercise components in the players’ exercise program.

Bio-banding in academy football: player’s perceptions of a maturity matched tournament

Background: Individual differences in biological maturation impact player selection and development in youth football.Aim: To evaluate players perceptions of competing in a football tournament where they were matched by maturity rather than chronological age.Subjects: Participants included male junior footballers from three professional academies (n = 115).Methods: The study employed multiple methods of analysis, including one sample mean t-tests, equivalence tests, ANOVAs, and thematic analysis of qualitative data derived from open-ended questions.Results and conclusions: Player’s perceived the bio-banding format as providing two main benefits. Early maturing players perceived greater physical and technical challenge, and in turn new opportunities and challenges. Late maturing players perceived less physical and technical challenge, yet greater opportunity to demonstrate technical and tactical abilities. The players reported that they enjoyed and understood the purpose of the bio-banded format, and perceived less risk for injury. Players in all three maturity groups reported more opportunity to engage in leadership behaviours, influence game-play, and express themselves on the ball in the bio-banded format. Bio-banding may facilitate development for both early and late maturing academy players by presenting new learning environments and challenges.

Evaluating the impact of a coach development intervention for improving coaching practices in junior football (soccer): The “MASTER” pilot study

ABSTRACT The aim of this pilot study was to evaluate the impact of a novel coach development intervention (MASTER) on coaching practices of football coaches. The study involved six coaches (of 10–12 year old) from one representative football club (Australia February–July 2017). The 15-week multi-component intervention included a face-to-face workshop, ongoing mentoring, modelled training sessions, peer assessments and group discussions. MASTER is underpinned by positive coaching and game-based coaching practices and aimed to educate coaches on how to implement and operationalise a number of evidence-based coaching elements. At each of baseline and immediate post-intervention coaches were filmed three times and evaluated using a modified version of the Coach Analysis Intervention System. Using linear mixed model analysis, significant changes were observed for time spent performing playing-form activities [+15.4% (95% CI 6.01–24.79)(t(15) = 3.5, P = 0.003], with significant changes in the type of interventions undertaken and the nature of feedback given to athletes. Program feasibility was examined using measures of recruitment, retention, adherence and satisfaction. Results indicate program feasibility and high coach evaluation ratings. MASTER demonstrated effectiveness for improving coaching practices of football coaches during training sessions. Further large-scale trials will build evidence for the utility of MASTER for guiding coaching practices in football and other sporting codes.

Implementing health policies in Australian junior sports clubs: an RCT

BackgroundThis pilot study aimed to test the potential effectiveness and acceptability of an intervention to support the implementation of 16 recommended policies and practices to improve the health promotion environment of junior sporting clubs. Reported child exposure to health promoting practices at clubs was also assessed.MethodsA cluster randomised trial was conducted with eight football leagues. Fourty-one junior football clubs belonging to four leagues in the intervention group received support (e.g. physical resources, recognition and rewards, systems and prompts) to implement 16 policies and practices that targeted child exposure to alcohol, tobacco, healthy food and beverages, and participation in physical activity. Thirty-eight clubs belonging to the four control group leagues did not receive the implementation intervention. Study outcomes were assessed via telephone interviews with nominated club representatives and parents of junior players. Between group differences in the mean number of policies and practices implemented at the club level at follow-up were examined using a multiple linear regression model.ResultsWhile the intervention was found to be acceptable, there was no significant difference between the mean number of practices and policies reported to be implemented by intervention and control clubs at post-intervention (Estimate − 0.05; 95% CI -0.91, 0.80; p = 0.90). There was also no significant difference in the proportion of children reported to be exposed to: alcohol (OR 1.16; 95% CI 0.41, 3.28; p = 0.78); tobacco (OR 0.97; CI 0.45, 2.10; p = 0.94); healthy food purchases (OR 0.49; CI 0.11, 2.27; p = 0.35); healthy drink purchases (OR 1.48; CI 0.72, 3.05; p = 0.27); or participation in physical activity (OR 0.76; CI 0.14, 4.08; p = 0.74).ConclusionsSupport strategies that better address barriers to the implementation of health promotion interventions in junior sports clubs are required.Trial registrationRetrospectively registered with the Australian New Zealand Clinical Trials Registry (ACTRN12617001044314).

Differentiation of T-wave Inversion Changes with Borderline Left Ventricular Hypertrophy in an Asymptomatic Young Athlete – Case Report and Literature Review

This is a case of initially 15 years of age, white, male from junior football team. He was completely asymptomatic, with no previous medical history or family history of sudden cardiac death and cardiac diseases. He has been playing football for 8 years. On periodic preparticipation screening, he presented T-wave inversions (TWIs) in leads V4–V6 and II, III, and aVF, which were not observed before on yearly screenings. Subsequently, he underwent echocardiography, which showed mildly increased myocardial thickness (13 mm) without other abnormalities. He was then referred to for further testing, which is discussed in the context of the current literature. Finally, management is presented.

Injury incidence in semi-professional football claims for increased need of injury prevention in elite junior football.

Injuries are a common occurrence in football. Sufficient epidemiological data are available in professional football but not in salaried semi-professional football. This study investigates the injury incidence at different levels of semi-professional football with focus on junior football. The data were based on injury reports provided by players and medical staff over the 2015-2016 season, which corresponded to the consensus statement for data samples in football. This study investigated the injury incidence and prevalence of five skill levels of semi-professional football (the fourth to the seventh league and elite junior football). 1130 players had sustained 2630 injuries over the 2015-2016 season. The overall injury incidence was 9.7 per 1000h football exposure; prevalence with at least one injury was 79%. The highest overall injury incidence in elite junior football was 10.4 in 1000h football exposure. The fifth league had the lowest incidence with 9.0 in 1000h football (p < 0.05). Traumatic injuries most often occurred in the fourth league (3.9 in 1000h football). The body areas most affected by traumatic injury were knees, ankles and thighs. Elite junior players had a significantly higher incidence of overuse complaints (7.4 in 1000h football) than the fourth league (5.4, p = 0.005). The body areas most affected by overuse complaints were the lower back, thigh and groin. No differences were found between the different positions on field. Salaried semi-professional football involves a high overall injury incidence. The highest incidence, particularly of overuse injuries, was seen in elite junior football. These findings should be incorporated in specific injury prevention training or screenings beginning in junior football. Level of evidence II.

Genetic and phenotypic markers for successful athletic performance forecast

In the modern research and practical provisions for the children’s and adolescent sports, due emphasis will be made on a timely detection of the physical activity limiting factors and prudent initiatives to remove or mitigate these factors with the relevant correction tools being applied to attain the highest competitive performance standards with no detriment for the athlete’s health.&#x0D; Based on the study of the 5HTT gene polymorphisms in junior football and ice hockey players, about 25% and 20% of the football and ice hockey players, respectively, were diagnosed with the unfavourable genetic type predisposed to indirect aggression that may be of negative effect on their training and competitive activities.&#x0D; The functional deviations identified by the study dictate the need in a reasonable pharmacological intervention to optimize the metabolic processes in the CNS and VNS and help maintain the high physical and mental workability rates.

Relegation of disabled children to lower age-levels in junior football – results and limitations of inclusion in recreational football

ABSTRACTBackground: Inclusion of disabled persons is one important fundament of the modern society. The implementation of inclusion of disabled athletes in football corresponding to the UN human rights convention is in discussion. Because of significantly higher limitations of disabled athletes in junior ages, inclusion activities should start in junior football and first findings are presented in this study.Methods: In a retrospective trial over 4 football seasons, all inclusion measures of a regional football association in Germany were descriptively analysed. Instrument of the inclusion measures in junior football was the relegation of disabled children to the next lower age level.Results: 329 (49%) of 671 applications for a temporary inclusion measure were approved and in detail investigated. Medical reasons for inclusion were mainly general physical retardation (46%), severe disability (23%), chronic cardiopulmonary disease (6%), orthopaedic disease (6%), which were mainly performed in the pre-pubertal age group under 11 years. As high as 84% of disabled children were satisfied with a 1-year inclusion measure, while 16% showed the need for repeated inclusion activity of more than one season, mainly with neurological disease (38%). No case of termination of the inclusion measures because of any incidents was seen.Conclusion: The results of this study emphasize for the first time implemented criteria and successful implementation of inclusion measures for disabled children in junior football by relegation to a lower age level.

The nature and function of talent identification in junior-elite football in English category one academies

The focus of this study was to examine the nature and function of talent identification in category one football academies in the UK. Data were collected from three participant groups: heads of recruitment (n = 12), recruitment staff (n = 18) and scouts (n = 7). Data were collected by means of semi-structured interviews, conducted either face-to-face or via Skype®. Four themes emerged from the data: (1) league structures in junior grassroots football; (2) reflective practice; (3) looking at the whole player; and (4) luck. The paper concludes by suggesting that there are issues that need to be considered by the football association, county football associations and clubs. Those issues include the organization of leagues in junior football, the education of scouts and recruitment staff around reflective practice and understanding how to identify psycho-social attributes whilst identifying talent.

Asymmetry during Functional Movement Screening and injury risk in junior football players: A replication study.

An indicator of movement quality and potential injury risk during Functional Movement Screen (FMS) testing is the presence of asymmetry when comparing the left and right sides of the body. The aim of the study was to investigate the reproducibility of the injury risk model proposed in our previous research (Chalmers etal. 2017; derivation study) that showed an increased injury risk for elite junior Australian football players demonstrating ≥2 asymmetrical FMS subtests. We used a direct replication design. Players underwent pre-season FMS testing, and an injury surveillance system monitored 277 male participants during the subsequent regular season competition. Designated club officials monitored the weekly competition participation of players. The definition of an injury was "a trauma or medical condition which caused a player to miss a competitive game". Cox proportional hazards regression models were used to investigate the relationship between asymmetry and number of games played before first injury (ie, survival time). The level of reproducibility was determined according to statistical significance, effect size, and subjective assessment. Demonstrating asymmetry during FMS testing was not associated with a significant increase in prospective injury risk in the replication study (P>.05). Moreover, effect sizes (hazard ratios) from the derivation dataset were not within the 95% confidence intervals of the respective asymmetry predictor in the replication dataset. Subjectively, researchers were in agreement that the findings from the derivation data were not successfully reproduced. Clinicians and researchers should be cautious about using FMS asymmetry findings to derive injury risk for junior football players.
