In this study, we compared the growth, maturity status, functional capacity, sport-specific skill, and goal orientation of 159 male soccer players, aged 11-12 (n = 87) 13-14 years 72) years, who at follow-up 2 later discontinued participation (dropout), continued same standard (club) or moved to a higher level (elite). Age group-specific multivariate analysis variance was used for comparisons. Among 11- 12-year-old players baseline, gradient elite > club dropout suggested size function,...
Background: Participants in many youth sports are commonly combined into age groups spanning 2 years.
Adolescence is often viewed as a critical period for selection in youth soccer. The present study compared the characteristics of regionally selected and non-selected under-14 players (U-14) group by position. Players were classified local (n=69) regional (n=45). Weight, height, skinfolds, functional capacities, soccer skills goal orientation measured skeletal age was assessed with Fels method. Factorial ANOVA used to test effect selection, position respective interaction terms, while...
The relationships among indicators of biological maturation were evaluated and concordance between classifications maturity status in two age groups youth soccer players examined (11-12 years, n = 87; 13-14 93). Data included chronological (CA), skeletal (SA, Fels method), stage pubic hair, predicted at peak height velocity, percent adult height. Players classified as on time, late or early using the SA-CA difference, mature Factor analyses indicated factors aged 11-12 years (maturity...
In young athletes, demands of sports are superimposed on normal growth and maturation. It has been suggested that this causes a temporarily increased vulnerability for injuries. We followed 26 talented soccer players (mean age 11.9±0.84 years) longitudinally 3 years around their adolescent spurt, called Peak Height Velocity, to identify differences in number traumatic overuse injuries days missed due Velocity was calculated according the Maturity Offset Protocol. The each player per year. A...
Background During childhood and adolescence, both physical activity (PA) sedentary behaviour seem to influence cardiorespiratory fitness (CRF); however, the combined association of PA remains be understood. We analysed objectively measured moderate-to-vigorous intensity (MVPA) on CRF in Portuguese children adolescents. Methods The sample comprised 2506 healthy adolescents aged 10–18 years, from a cross-sectional school-based study (2008). were assessed with accelerometry. Participants...
Anthropometric characteristics, physical fitness and technical skills of under-19 (U19) soccer players were compared by competitive level (elite, n=95; non-elite, n=85) playing position (goalkeeper, central defender, fullback, midfield, forward). Fitness tests included 5- 30-m sprints, agility, squat jump (SJ) countermovement (CMJ), strength Yo-Yo intermittent endurance test 2 (Yo-Yo IE2). Soccer-specific ball control dribbling. Independent position, elite presented more hours training per...
Predictors of functional capacities and skills in 143 soccer players aged 11-14 years from five clubs Portugal were investigated. Data for 11-12 (n=75) 13-14 (n=68) included chronological age, skeletal stage pubic hair (PH), anthropometry, four capacities, experience; composite skill scores derived. Multiple linear regression analysis was used to examine the independent effects maturity, body size proportions, adiposity experience on individual scores. Explained variances differed among...
Abstract The aim of the study was to estimate influence body size and pubertal status on variation in functional capacities sport‐specific skills 59 youth basketball players aged 14.0–15.9 years. Height mass were measured stage pubic hair assessed at clinical examination. Six tests capacity evaluated: squat jump, countermovement 60‐s sit‐ups, 2‐kg standing medicine ball throw, hand grip strength, 20‐m multi‐stage shuttle run. Four tested (shooting, passing, dribbling, defensive movements)....
This study determined the prevalence of overweight, obesity, and abdominal obesity in Portuguese adults examined relationship between above mentioned prevalences educational level. Body mass, stature, waist circumference were measured a representative sample population aged 18–103 years (n = 9,447; 18–64 years: n 6,908; ≥65 2,539). Overweight corresponded to body mass index ranging 25–29.9 kg/m2 ≥30 kg/m2, respectively. Abdominal was assessed as >102 cm for males >88 females. After adjusting...
The weakening of the cardiovascular system associated with aging could be countered by increasing levels physical activity and functional fitness. However, inconsistent findings have been found, variety characteristics exercise used in previous studies may partly explain that results. To investigate training effect sixteen weeks moderate intensity, progressive aerobic strength-based on metabolic health older women men. Sixty three sedentary individuals (mean (SD) age 76 (8) years) were...
Research considering physical activity (PA), inactivity and health outcomes among urban rural youth has produced equivocal findings. This study examined PA, inactivity, sedentary behaviours cardiorespiratory fitness (CRF) in adolescents from communities the Portuguese Midlands. The sample included 362 (165 males, 197 females) of 13–16 years age. CRF was assessed by PACER test. A GT1M accelerometer used to record 5 consecutive days PA time spent sedentary. Analyses covariance (chronological...
The present study determined to what extent the variance in performance might be explained by chronological age, biological maturation, training load and anthropometry 168 Belgian male handball players aged 14 years: anthropometric, strength, speed sport-specific skills were assessed. MANOVA tested effect of age maturity, whereas MANCOVA was used compare maturity groups controlling for load. In addition, canonical correlation analysis between maturity-offset anthropometry, on one side,...
Physical activity is important in obesity prevention, but the effectiveness of different physical modalities remains to be determined among children. The main purpose this study was compare effects a 6-month soccer programme and traditional on changes body composition, cardiometabolic risk factors, inflammatory oxidative markers, cardiorespiratory fitness perceived psychological status obese boys. Eighty-eight boys (8-12 years; BMI > +2 standard deviations WHO reference values) participated...
Discussions of growth and motor performance children are often set in the context physical fitness. Although there is a clear theoretical concept or definition fitness comprising coordination, latter not systematically considered. This study determined to what extent variance coordination might be explained by morphological characteristics. To postulate understanding this association during childhood, 613 boys aged 7–11 years completed measurements, Körperkoordinationstest für Kinder (KTK)...
A model for adolescent involvement in physical activity (PA) that incorporates individual differences biological maturation is presented. The biocultural of maturity-associated variance recognizes PA as a complex and multifaceted behaviour exists multiple contexts (e.g., transport, vocation, sport, exercise) can be viewed from perspectives energy expenditure, movement counts, performance outcomes, fitness). holds exert both direct indirect effects on during adolescence. Direct imply...
Sex differences in physical activity (PA) through pubertal maturation and the growth spurt are often attributed to changing interests. The contribution of sex biological adolescent decline has received limited attention. This study examined somatic objective assessments sedentary behavior PA Portuguese adolescents ( N = 302, aged 13–16 years). Maturation was estimated from percentage predicted mature stature physically active inactive behaviors assessed with Actigraph GT1M accelerometers....
