Siegerinnen, Medaillen, Verlierer und Tränen!-Im gnadenlosen Wettkampf des Sports werden wahre Helden geboren. Von der ersten Sekunde an treten junge Athletinnen und Athleten in eine Arena ein, in der nur die Stärksten überleben. So wird es oft von den Medien dargestellt. Doch wollen wir das wirklich? Es gibt auch andere Wege, wie ein Projekt von S...
Introduction
To perform a successful action in football, players must constantly recognize the given affordances and their surroundings on the field before and during action (McGuckian et al., 2020). Therefore, having the ability to temporarily detach the view from the ball and move the head to scan the environment to identify and recognize inform...
As young football players develop important technical and tactical skills during competitive matches, this study investigated quantity and quality of technical and tactical actions in real game conditions in a 4v4 compared to the traditional 7v7 match format. In total, three matches of each format were played by 103 young football players (10.3±0.6...
Eine Studie im Schweizer Kinderfussball zeigt, dass ein neues Wettspielformat die Anzahl technischer und taktischer Aktionen im Vergleich zum traditionellen Format um 62 % erhöht. Beim neuen Spielformat «play more football» wird das traditionelle Grossfeld-mit einem zusätzlichen Kleinfeldspiel kombiniert.
La catégorisation par âge chronologique se révèle un marqueur discriminatoire dans le sport. Cette méthode crée des inégalités, souvent à la faveur des jeunes nés en début
d’année ou de ceux à développement précoce, ce qui se traduit par une perte de talents. Pourtant d’autres voies existent. Elles sont testées notamment à l'Association suisse de f...
Purpose:
In this study, we tested the hypothesis that augmented feedback (AF) training can improve both perceptual-cognitive and/or motor skills specific to soccer.
Methods:
Three groups of young elite players (U14-U15 categories) performed a test consisting in passing the ball as accurately and as quickly as possible towards a visual target mov...
Abstract in English for ‘Bio-banding – Bessere Talententwicklung im Nachwuchsfussball’
WHAT IS BIO-BANDING? During adolescents the biological age (BA) can vary up to five years among athletes with the same chronological age (CA). Bio-banding matches the training and competition groups according to BA rather than the CA.
AIM OF THE REVIEW ARTICLE...
Introduction
In youth soccer, the chronological age is used to group and select the athletes for training and competition. Within these age groups, individuals can differ by as much as 1 year in relative age, which might affect the talent selection process and benefit the athletes born early in the year. Moreover, the biological age varying by 4 ye...
Background
To improve soccer specific skill acquisition the match play in children’s soccer should be designed to maximize the individual playing time and game involvement. Small-sided games showed an increased individual playing time, individual game involvement, number of ball contacts, variability and frequency of game situations, and positional...
Consideration of maturity is recommended in the talent identification and development process. Skeletal age (SA), prediction of age of peak height velocity (APHV) and an estimation of biological maturation by coaches' eye of 121 soccer players were compared. The SA of soccer players was 13.9 ± 1.1 years, and did not differ significantly from chrono...
Nachwuchsförderung und Talentselektion werden in der Schweiz als eine zentrale Komponente der Spitzensportförderung angesehen. Deshalb investiert das Bundesamt für Sport (BASPO) jährlich rund elf Millionen Schweizer Franken im Rahmen der „Jugend und Sport Nachwuchsförderung“ in die leistungsorientierte Nachwuchsförderung. Zusätzliche Unterstützung...
Durch die Einteilung in Alterskategorien kommt es zu relativen Altersunterschieden unter
Fussballspielern im Kindes- und Juniorenalter. So hat ein Spieler, der kurz nach dem Stichtag geboren
ist (im Januar), im Vergleich zu einem Spieler, der spät im Selektionsjahr geboren ist (im Dezember),
einen entscheidenden Entwicklungs- und Leistungsvorteil....
La répartition des footballeurs par classes d'âge donne lieu à des différences d'âge relatives parmi les enfants et parmi les juniors. Ainsi, un joueur né peu après la date limite utilisée pour déterminer la classe d'âge (en janvier) aura un net avantage en termes de développement et de performance par rapport à un joueur né vers la fin de l'année...
Physical performance is highly dependent on maturity. Therefore, consideration of maturity is recommended in the talent identification process. To date, skeletal age (SA) is assessed using X-ray scans. However, X-rays are associated with a tenfold higher radiation compared to dual energy X-ray absorptiometry (DXA). The aim of the study was to valid...
Introduction Biological maturation (BM) of young athletes is implicit in models of talent identification, selection, and development. In several elite team sports proportionally more players were detected who are advanced (early) in BM and proportionally fewer players who are delayed (late) in BM (Malina, et al. 2012). The aims of the present study...
Background: The second-to-fourth digit-length ratio (2D:4D) may be a correlate of prenatal sex steroids, and it has been linked to sporting prowess. The aim of the study was to validate dual-energy X-ray-absorptiometry (DXA) as a technique to assess 2D:4D in soccer players under 15 years of age (U-15).
Methods: Paired X-ray and DXA scans of the lef...
Relative age refers to age differences between children in the same selection year. The present study investigated the prevalence of relative age effects (RAEs) at the Grand Prix Migros (GPM), which is the most popular alpine skiing race for children aged 7 to 14 years in Europe. In total, 17,992 Swiss junior alpine skiers, separated into female sk...
Relative age effects (RAEs) refer to age differences among athletes in the same selection year. This
study analysed birth date distributions of 301,428 female athletes (aged 10–20 years) in Swiss Youth sports and the subgroup (n=1,177) of the national Talent Development Program (TDP) in individual sports. Comparisons showed significant RAEs in the...
The high performance unit within the Swiss Federal Institute of Sports Magglingen (SFISM) is chartered with supporting talented athletes via its collective inputs to students, athletes, coaches and national sporting federations. This is achieved by drawing upon the multi-disciplinary expertise of practitioners in the areas of sports medicine, recov...
Abstract Relative age effects (RAEs) refer to age differences between children in the same selection year. The present study investigated the prevalence of RAEs and their link to playing positions in Swiss junior soccer. Swiss male junior soccer players (n=50,581) representing 11% of the age-matched population - members of extra-curricular soccer t...
Abstract Previous research has shown that young male soccer players who are born early in a cohort are overrepresented on elite soccer teams. Selection advantages such as this have been termed 'relative age effects' (RAEs). Few studies have examined RAEs in elite women's youth soccer. Therefore, the aim of this study is to investigate the occurrenc...
Introduction: Jugendliche desselben chronologischen Alters haben während der Pubertät oft einen unterschiedlichen biologischen Entwicklungsstand (BES), der bis zu 5 Jahre vom chronologischen Alter abweichen kann (Malina, Bouchard, & Bar-Or, 2004). Dies hat zur Folge, dass in Nachwuchskader hauptsächlich früh entwickelte Athleten, die einen körperli...
Relative age effects (RAEs) refer to age differences in the same selection year. In this study, 6,229 female soccer players representing the entire Swiss female soccer population were evaluated to determine the prevalence of RAEs in Swiss women’s soccer. Significant RAEs existed in the self-selected extracurricular (n = 2987) soccer teams and the s...

Several studies (on an inclined platform or with special shoes) have reported improved jump performance when the ankle was in a dorsiflexion (DF) position. The present study aims to test whether shoes inducing moderate DF modify vertical jump performance and energy cost. Twenty-one young, healthy female subjects (30 +/- 6 yr, 58 +/- 6 kg, O2max 45...
The aim of the present study was to compare electromyographic activity during fitness exercises, walking, and running among 3 different dorsiflexion shoes (+2 degrees , +4 degrees , and +10 degrees ) and standard shoes (-4 degrees ). The 3 different dorsiflexion shoes tested in this study have a curvature placed in the middle of the sole. This desi...
The goal of this study was to use spectral analysis of EMG data to test the hypothesis that the O2 uptake VO2) slow component is due to a recruitment of fast fibers. Thirteen runners carried out a treadmill test with a constant speed, corresponding to 95% of the velocity associated with maximal VO2. The VO2 response was fit with the classical model...
