Kicking powerfully and accurately is essential in soccer, players who kick proficiently with both feet are highly sought after. Assessing performance youth often confounded by more physically developed outperforming their smaller peers. To alleviate such bias, we present a testing protocol normative data an elite Brazilian soccer academy that controls for players’ age size to assess feet. We measured speed accuracy of 178 recorded (10–20 years), height, mass. Combining age, mass into index...
Prior research has suggested relevance to anthropometric variance of youth athletes at various stages their maturation, and prior studies players’ soccer skills have failed consider interdependent interactions during play. Accordingly, address both these separate omissions, we aimed in this study analyze the relationships between young (U-13 U-15 groups) bone age body size indicators centrality measures pass small sided games. We included 81 ( M = 14.4, SD 1.1 years) from whom took...
This study verified the effects of body size and game position on interactions performed by young soccer players in small-sided games (SSG). The sample consisted 81 Brazilian (14.4 ± 1.1 years age). Height, mass, trunk-cephalic height were measured. SSG was applied GK + 3v3 format, Social Network Analyses carried out through filming to obtain following prominence indicators: degree centrality, closeness prestige, proximity addition network intensity number goals scored. Factorial ANCOVA...
Aim: The aim was to compare performance in specific-skill tests and motor coordination between groups with different technical efficiency verify possible variables related specific skills that contribute discriminate players into high- low-technical efficiency. Methods: sample consisted of 82 young soccer (12-15 years). Body size, bone age, tests, soccer-specific skill frequency actions SSG were analyzed. Statistic cluster-derived ANOVA F used identify which action most contributed...
ABSTRACT The aim of the study was to compare isokinetic performance (PT) knee extensors (ext) and flexors (flex), H:Q ratio, PT asymmetry in young soccer players based on somatic maturation. 80 (aged 12-17) were sampled, classified as pre-PHV (n=19) post-PHV (n=61). Isokinetic dynamometry assessed extensors/flexors at 60º/s. Pre-PHV had lower body mass/height than (P < 0.001). exhibited for dominant non-dominant leg ext flex No differences (ext: 31.6% vs 31.1%; flex: 34.4%) ratio...
The aim of this study was to evaluate the relative age effect (RAE) in Brazilian male handball teams who competed world championships U-19, U-21, and adult categories. sample composed by 160 players, 47 players being on U-19 category, 48 65 Adult category. chronological age, body mass, height, game position each athlete were obtained International Federation Handball website. adopted significance level 5%. RAE observed all three following categories (X2=21.511, P<0.01), U-21 (X2=15.894,...
Abstract This study verified the relationship between body size and skeletal age (SA) with behavior of blood markers muscle damage delayed onset soreness (DOMS) after a soccer match in U-13 U-15 categories. The sample consisted 28 players 16 Creatine kinase (CK), lactate dehydrogenase (LDH), DOMS were evaluated up to 72 h match. Muscle was elevated at 0 U-13, from 24 U-15. increased 48 Significant associations SA fat-free mass (FFM) observed only specifically time h, when explained 56% CK...
Abstract This study verified the effects of maturity status on interactions young soccer players in small-sided games. The sample included 81 (14.4 ± 1.1 years). Anthropometric measurements body mass, height, sitting and bone age were obtained (TW3 method). multidimensional evaluation involved following tests: Yo-Yo Intermittent Recovery Test Level 1 (YYIRT1), Counter Movement Jump (CMJ), Repeated Sprints Ability (RSA), observational analysis techniques, performed by relationship between set...
Abstract This study aimed to observe the relationships between maturity status on network-based centrality measures of young athletes in small-sided soccer games (SSG). The included 81 male players (14.4 ± 1.1 years). Measurements height, sitting body mass, and bone age (TW3 method). applied protocols were following: Countermovement Jump (CMJ), Yo-Yo Intermittent Recovery Test Level 1 (YYIRT1), Repeated Sprints Ability (RSA), observational analysis techniques, interactions performed by SSG....
