Abstract The aim of this study was to analyse the effects of the modification of the pitch size, goal size, and the number of players per team on the level of cooperation in youth soccer players (U-12). A quasi-experimental design was implemented to measure the effects of the changes in the number of players per team (8-a-side vs. 5-a-side), goal size (6 x 2 m vs. 3 x 2 m), and field size (58 x 38 m vs. 38 x 20 m) on the cooperation. Four soccer teams under-12 (n = 48 players) participated in three tournaments (standard rules; proposed rules; standard rules). The five variables of cooperation were measured using the “Sports Cooperation Questionnaire”: conditional cooperation, cooperation with the coach, disposition of unconditional cooperation, situational cooperation with teammates, and situational cooperation outside the field of play. Players presented the same level of cooperation in conditional cooperation, situational cooperation with teammates, and situational cooperation outside the field of play with both types of rules. The modification of rules involved a reduction of the cooperation with the coach and a disposition of unconditional cooperation. The causes of the reduction may be related to players’ adaptation to new tactical dispositions and game situations. Future studies are needed of player’s cooperation and different competition rules in youth sports.

The purpose of this study was to assess the effect of modifications in field size, number of players, and goal size on the goalkeeper's actions in competition in male youth soccer ( n = 4) (under-12). A quasi-experimental design was implemented to measure the effects of the changes in the number of players per team (8-a-side vs. 5-a-side), goal size (6 × 2 m vs. 3 × 2 m), and field size (58 × 38 m vs. 38 × 20 m) on the offensive and defensive technical and tactical actions of the goalkeeper. Four male under-12 goalkeepers (age = 11.33 ± 0.6 years, average weekly training = 2.45 ± 0.3 h, and years of experience = 4.8 ± 0.9 years) were analyzed in three tournaments (8-a-side; 5-a-side; 8-a-side). The dependent variables were: defensive and offensive technical actions taken by the goalkeepers and the way their actions were carried out. The results show that in the 5-a-side soccer matches, goalkeepers carried out more defensive actions (8-a-side: 31.2 ± 3.8; 5-a-side: 77.75 ± 5.0; 8-a-side: 39.5 ± 6.0; F2,6 = 111,218, p = .000, η2 = .974; ES .998) and offensive actions (8-a-side: 58.0 ± 7.1; 5-a-side: 84.0 ± 13.5; 8-a-side: 58.1 ± 9.2; F2,6 = 16,257, p = .004, η2 = .844; ES .996) than in 8-a-side soccer matches. The reduction in field size, number of players, and goal size resulted in under-12 goalkeepers having more interaction and more variability in their actions. This information could help the different stakeholders to adapt or design the youth soccer competition rules in a way that allows goalkeepers to have more experiences.

Abstract The identification of talent in soccer is critical to various programs. Although many research findings have been presented, there have been only a few attempts to assess their validity. The aim of this study was to determine the relationship between talent and achievement variables in the Vienna Test System. The participants were 91 Czech soccer players, representing four youth soccer teams, who were born in the year 2000. These boys were divided into two groups according to their coaches’ assessments using a TALENT questionnaire. A two-factor model (component 1: “kinetic finesse”; component 2: “mental strength”) was designed to interpret the responses of the coaches on the questionnaire. The Vienna Test System was used to determine the level of players’ cognitive abilities. In total, the subjects performed seven tests in the following order: Raven’s Standard Progressive Matrices (SPM), a reaction test (RT), a determination test (DT), a visual pursuit test (LVT), a Corsi Block-Tapping Test (CORSI), a time/movement anticipation test (ZBA), and a peripheral perception test (PP). To analyze the relationship between talent and achievement variables within the Vienna Test System, correlation analyses were performed. The results revealed that the talented group attained significantly better results on only 1 of the 16 variables, which was ZBA2: movement anticipation - deviation of movement median (r = .217, p = .019). A comparison of the two talent components showed that component 1 (“kinetic finesse”) was a more significant factor than component 2 (“mental strength”). Although we observed statistically significant correlations, their actual significance remains questionable; thus, further research is required.

LANGUAGE NOTE | Document text in English; abstract also in Chinese. The purpose of this study is to investigate the heart rate (HR) repose and repeated-sprint performance throughout the match among Chinese elite youth soccer players. Two elite youth soccer teams each consisted of 11 players participated in the study. The HR measurement and repeated-sprint test were conducted (age: 17.1±0.85, height: 173± 5.2cm; weight: 64.2± 8.1kg). HR was recorded every 5s throughout the match, while repeated-sprint consisted of three 30m sprints separated by a 25s active recovery period that was conducted: 5min before the match (T1), 5min before the end of the first half (T2), 5min before the start of the second half (T3), and 5min before the end of the second half (T4). HR was in the range of 160-169bpm for 25% of total play time, followed by 170-179bpm for 23.6%. HR during the 46-60min was significantly lower than other intervals (P<0.05), and repeated-sprint time at T3 was significantly slower than others. The intensity of the match was lower than those found in European players, indicating the cardiovascular fitness and repeated-sprint performance are needed among the players. High-intensity and low-volume interval training, and re-warm up before the start of second half are suggested in the training program. 本研究旨在測定中國青年足球運動員比賽時的心率及重覆衝跑測試表現。對兩支分由11人組成的足球隊運動員(年齡17.1±0.85歲，身高：173±5.2釐米，體重; 64.2±8.1公斤)進行了心率測量以及重覆衝跑測試。比賽時每5秒鍾記錄一次心率。重覆衝跑測試由3次30米衝跑組成，每次有25秒動態休息。重覆衝跑測試共進行四次，分別在：賽前5分鐘(T1)，中場前5分鐘(T2)，下半場開始前5分鐘(T3)及比賽結束前5分鐘(T4)進行。結果在25%的比賽時間內，運動員的心率在每分鐘160-169之間，其次是23.6%的時間內為每分鐘170-179。在46-60分鐘的比賽中，運動員的心率顯著低於其他時段(P<0.05),而運動員在第三次重覆衝跑測試時的速度顯著低於其他三次測試。本次研究結果顯示比賽強度低於歐洲青年足球員進行的同類測試，說明中國青年足球運動員需要加強心肺功能及提高重覆衝跑的表現。建議訓練時進行大強度低密度的間歇訓練，及在比賽中場開始前再次進行熱身。

The ability of young athletes to effectively cope with stressors is crucial for sustained sport enjoyment and participation, and parents play a key role in providing coping support. However, there is limited evidence for coping interventions directed at both youth athletes and their parents. The purpose of this study was to implement a coping workshop for youth athletes and also engage parents to provide them with information to support the development of coping skills among young athletes. Athlete–parent dyads from a high-performance soccer academy were assigned to either a 4-wk coping intervention or a control group using a matched quasi-experimental design. Survey data were analyzed using 2-factor repeated-measures ANOVAs and multiple-regression analyses. Results indicated that lower parental pressure and greater coping self-efficacy predicted lower stress in youth athletes. However, findings for the intervention in reducing overall stress and perceptions of parental pressure were not significant. Future coping intervention studies should address study design considerations related to timing, intervention modalities, and skill level of youth athletes.

The purpose of this study was to examine personal and socioenvironmental factors of players' likelihood to aggress. Participants were youth soccer players (N = 258) and their coaches (N = 23) from high school and club teams. Players completed the Judgments About Moral Behavior in Youth Sports Questionnaire (JAMBYSQ; Stephens, Bredemeier, & Shields, 1997), which assessed athletes' stage of moral development, team norm for aggression, and self-described likelihood to aggress against an opponent. Coaches were administered the Coaching Efficacy Scale (CES; Feltz, Chase, Moritz, & Sullivan, 1999). Using multilevel modeling, results demonstrated that the team norm for aggression at the athlete and team level were significant predictors of athletes' self likelihood to aggress scores. Further, coaches' game strategy efficacy emerged as a positive predictor of their players' self-described likelihood to aggress. The findings contribute to previous research examining the socioenvironmental predictors of athletic aggression in youth sport by demonstrating the importance of coaching efficacy beliefs.

The Difference

Growth and maturation are central concerns in the organization of training and competitions in youth sports. This study examined maturity-associated variation in body size and adiposity among adolescent girls participating in competitive age group youth soccer. The sample included 441 players 10.08-16.73 years of age. Stature and body mass were measured and body composition was predicted. The Fels method was used to estimate skeletal age. Skeletally maturity status (late, average or early maturing) was based on the difference between chronological and skeletal age for each player. Mean stature approximated the 50th percentiles of the general population in all competitive age groups, while mean weight fluctuated between 50th and 75th percentiles. Age- and maturity-specific means for estimated fat mass ranged between 18.0% and 28.2%. The number of players classified as skeletally mature increased with competitive age groups (under-13: 0%; under-15: 8%; under-17: 49%). In general, early maturing girls tended to be heavier than their age group peers and especially when compared to late maturing players.

The purpose of this study was to examine the influence of chronological age (CA) and somatic maturation on body composition (BC) and bioimpedance parameters in male elite soccer players. BC and bioimpedance variables were measured in a sample of 249 players aged 9−18 years of age and registered in two professional Italian soccer teams. Results from segmental analysis showed transition time points where the influence of CA and somatic maturation on bioimpedance patterns and BC characteristics increased or subsided. The accelerated phases were assessed for fat free mass, total body water, and upper muscle area, with a starting time point at approximately −2.00 years from peak at velocity (YPHV), and for body cell mass, whose developmental tempo sped up around −1.00 YPHV. An increase in the rate of development was also observed close to −2.00 YPHV for phase angle (PA), although without accelerated phases. From a CA point of view, significant slope changes were found for all BC and bioimpendance variables, except for the calf muscle area. Although the starting points and the span of the accelerated phases were different, they subsided or disappeared at ~ 15 years, except for PA, whose growth waned at ~ 17 years.

Context: Epidemiologic information on the incidence of youth soccer injuries in southern Europe is limited. Objective: To compare the incidence, type, location, and severity of injuries sustained by male subelite youth soccer players over the 2008–2009 season. Design: Descriptive epidemiology study. Setting: Twenty-eight Portuguese male youth soccer teams. Patients or Other Participants: A total of 674 youth male subelite soccer players in 4 age groups: 179 U-13 (age range, 11–12 years), 169 U-15 (age range, 13–14 years), 165 U-17 (age range, 15–16 years), and 161 U-19 (age range, 17–18 years). Main Outcome Measure(s): Injuries that led to participation time missed from training and match play prospectively reported by medical or coaching staff of the clubs. Results: In total, 199 injuries reported in 191 players accounted for 14.6 ± 13.0 days of absence from practice. The incidence was 1.2 injuries per 1000 hours of exposure to soccer (95% confidence interval [CI] = 0.8, 1.6), with a 4.2-fold higher incidence during match play (4.7 injuries per 1000 hours of exposure; 95% CI = 3.0, 6.5) than during training (0.9 injuries per 1000 hours of exposure; 95% CI = 0.6, 1.3) (F1,673 = 17.592, P &lt; .001). The overall incidence of injury did not increase with age (F1,673 = 1.299, P = .30), and the incidence of injury during matches (F1,673 = 2.037, P = .14) and training (F1,673 = 0.927, P = .44) did not differ among age groups. Collisions accounted for 57% (n = 113) of all injuries, but participation time missed due to traumatic injury did not differ among age groups (F3,110 = 1.044, P = .38). Most injuries (86%, n = 172) involved the lower extremity. The thigh was the most affected region (30%, n = 60) in all age groups. Muscle strains were the most common injuries among the U-19 (34%, n = 26), U-17 (30%, n = 17), and U-15 (34%, n = 14) age groups, whereas contusions and tendon injuries were the most common injuries in U-13 players (both 32%, n = 8). The relative risk of injury slightly increased with the age of the competitors. Conclusions: The higher incidence of injury during matches than training highlights the need for education and prevention programs in youth soccer. These programs should focus on coach education aimed at improving skills, techniques, and fair play during competitions with the goal of reducing injuries.

AbstractThe present study aimed to compare players’ tactical behaviour in 3 vs. 3 and 6 vs. 6 soccer small-sided games (SSGs). The sample comprised 3,482 tactical actions performed by 18 U-11 youth soccer players from a Portuguese club, in 3 vs. 3 and 6 vs. 6 SSGs. All participants played eight minutes in both situations and field size was adapted according to the number of players involved (30 m x 19.5 m for 3 vs. 3 and 60 m x 39 m for 6 vs. 6). The System of Tactical Assessment in Soccer (FUT-SAT) was used for data collection and analyses. Descriptive analysis was conducted to verify frequencies and percentages of the variables assessed. The chi-squared (χ2) test was performed to compare the frequencies of the variables between 3 vs. 3 and 6 vs. 6 SSGs and Standardized Residuals (e) were used to examine the influence of the frequency of one or more variables within 3 vs. 3 and 6 vs. 6 SSGs. Data treatment was performed through SPSS for Windows®, version 18.0. Results indicated that players displayed safer behaviours in 6 vs. 6 SSG and more aggressive behaviours in 3 vs. 3 SSG. Findings can aid coaches and teachers to develop different players’ tactical skills according to the chosen SSG (3 vs. 3 or 6 vs. 6) form.
