Biological and environmental determinants of 12-minute run performance in youth
Age and sum of skinfolds in both sexes and rural residence in boys are significant predictors of 12-minute run performance in Portuguese youth
Short-term secular change in height, body mass and Tanner-Whitehouse 3 skeletal maturity of Madeira youth, Portugal
The short-term trends for height and mass were not entirely consistent with the trends in RUS and Carpal SMSs and SAs
Tracking of fatness during childhood, adolescence and young adulthood
Over 7.2 years, tracking was moderate-to-high for fatness. Variance was explained by fatness indicators and to a small extent by physical fitness, physical activity and maturation
Cross-validation of the Beunen–Malina method to predict adult height
The purpose of this study was to cross-validate the Beunen-Malina method for non-invasive prediction of adult height. Three hundred and eight boys aged 13, 14, 15 and 16 years from the Madeira Growth Study were observed at annual intervals in 1996, 1997 and 1998 and re-measured 7-8 years later. Height, sitting height and the triceps and subscapular skinfolds were measured; skeletal age was assessed using the Tanner-Whitehouse 2 method. Adult heig…
Somatotype in 6–11-year-old Italian and Estonian schoolchildren
Secular trends in anthropometric characteristics, physical fitness, physical activity, and biological maturation in Flemish adolescents between 1969 and 2005
In this study, secular trends in anthropometric characteristics, physical fitness, physical activity, and biological maturity over the past 25–35 years in Flemish adolescents were investigated. Representative cross‐sectional samples of 12–18‐year‐old secondary school children (11,899 assessments in boys in 1969–1974, 4,899 girls in 1979–1980, 1,429 boys and 1,772 girls in 2005) and parent‐offspring pairs tested at approximately the same age durin…
Socio-economic status, growth, physical activity and fitness
Considerable variation in somatic growth and physical fitness in association with SES has been demonstrated, but little association was found for physical activity
Association between bone, body composition and strength in premenarcheal girls and postmenopausal women
In premenarcheal girls, bone is partly determined by mass, with lean mass the most important predictor at the femoral sites. In postmenopausal women, lean mass is an important determinant of bone mineral content (BMC) and BMD, but changes in BMD are related to changes in fat. The relation between strength and BMD is mainly attributable to the relation between lean mass and BMD. The contributory effects of soft tissue to bone change over different…
Skeletal maturity and socio-economic status in Portuguese children and youths
The data suggests population variation in TW2 estimates of skeletal maturation. Skeletal maturity was not related to SES in youths from Madeira
Modeling stability and change in strength development
The purpose of this study was to investigate stability and change in different expressions of strength development in adolescent boys using structural equation modeling. Three models were used: Markov simplex to study stability or tracking, Wiener or random walk to investigate fanning‐out or spread effects in change, and latent growth to study differences in individual pathways of change as well as group changes. In the Leuven Growth Study, 588 m…
Heritability of somatotype components from early adolescence into young adulthood
The finding of substantial genetic influence on the variability of somatotype components is further supported. The need to consider somatotype as a whole is stressed as well as the need for sex- and perhaps age-specific analyses. Further multivariate analyses are needed to confirm the present findings
Age at menarche in relation to anthropometric characteristics, competition level and boat category in elite junior rowers
Based on the results of this study, there is no direct evidence to state that intensive rowing training has a negative influence on the maturation status of junior female athletes
Health‐related quality of life in physically active and sedentary obese women
The aim was to assess dimensions of health‐related quality of life (HRQL) in women attending an obesity clinic, and to rate differences in HRQL in those with the highest and lowest levels of physical activity (PA). The sample included 113 sedentary and 101 physically active subjects from a total sample of 375 overweight women 16–65 years, with a body mass index (BMI) ≥27.5 kg/m 2 consulting at an outpatient Endocrinology Clinic, and 82 lean femal…
Association between bone mineral density (DXA), body structure, and body composition in middle‐aged men
The association between bone mass, body structure, and body composition was explored in 156 men, 40 years of AGE . Bone mineral density (total body, lumbar spine, left arm, and left leg) was obtained by dual‐energy X‐ray absorptiometry (DXA; Hologic QDR 4500A). Body structure was determined from a battery of anthropometric dimensions with a principal components analysis. Body composition was estimated with DXA. From the 24 anthropometric dimensio…
Adolescent physical performance and adult physical activity in Flemish males
Limited information is available about the associations between adolescent fitness levels and adult physical activity. In the present study, these associations are investigated using different indicators of physical activity. It is hypothesized that both health- and performance-related fitness characteristics, observed during the adolescent period, contribute equally to the explained variance in adult physical activity levels. Subjects were 109 F…

Daily physical activity and physical fitness from adolescence to adulthood
The stability of physical fitness and physical activity in Flemish males from 18 to 40 years of age was investigated. In addition, effects of a consistently low-activity or high-activity level during the same age period on physical fitness were studied. The sample consisted of males who were followed longitudinally from age 13 to age 18 years, and were remeasured at the ages of 30, 35, and 40 years. Complete data about physical fitness and physic…
Associations between daily physical activity and physical fitness in Flemish males
The relationship of physical activity to several components of physical fitness was investigated in a sample of 166 males 40 years of age. In addition to Pearson correlations, multivariate canonical correlations were calculated. Physical activity during work (work index), sport (sport index), and leisure time (leisure time index) was assessed by the Baecke questionnaire. Physical fitness included cardiorespiratory fitness measures, the body mass …

Accuracy of anthropometric estimation of muscle cross‐sectional area of the arm in males
Mid-arm cross-sectional muscle area was studied in several domains to evaluate nutritional status and muscle area and hypertrophy in revalidation and strength-related studies. In this study, anthropometrically determined muscle + bone area formulas were validated against Houndsfield unit-based CT-scan measures at mid-humerus (stretched and relaxed), and mid-humerus -3 and -6 cm positions in 75 healthy male twins. Muscle + bone area estimates calc…

A Longitudinal Study of Youth Sport Participation and Adherence to Sport in Adulthood
Youth sport programmes are often legitimized on their assumed contribution to continued sport involvement in adulthood. A longitudinal analysis was made of the sport involvement pattern of a sample ( N = 236) of male subjects from 13 to 35 years of age, from a perspective of continued socialization into sport. The results of the quantitative analysis show that the continuation of sport participation from youth into adulthood is different accordin…
Body size, biological maturation, and sport participation related to cortical bone in adolescent girls
The purposes of this study were twofold: (1) to describe the growth of metacarpal bone dimensions in a large sample (n = 819) of Flemish girls, 12–18 years, and (2) to investigate the relationship among cortical bone dimensions, biological maturation, and participation in sports activities. Besides body mass and stature, Tanner‐Whitehouse skeletal age (SA) was estimated and menarcheal status was assessed. Second metacarpal bone dimensions were me…
Secular trends in somatic and motor characteristics of physical education students
This study investigated changes in somatic and motor characteristics of 3,514 physical education students at the Katholieke Universiteit Leuven (Belgium) from the academic years 1941–1942 to 1988–1989. To facilitate data handling, the span of 47 years was divided into nine cohorts for anthropometric variables, and 4 cohorts for the motor data which were available only since the 1968–1969 academic year. A total of 21 anthropometric variables (sinc…
Sociogeographic variation in the physical fitness of a cross‐sectional sample of Flemish girls 13 to 18 years of age
Three aspects of physical fitness-somatic characteristics, motor fitness, and sport participation-of girls from different sociogeographic origins of Belgium were contrasted. The sample consisted of a cross-sectional sample of 4,528 Flemish girls 13 to 18 years of age, who were classified by dwelling area as rural, semi-urban, and urban. Somatic characteristics included 16 anthropometric dimensions, skeletal maturity, and somatotype. Motor fitness…

Stability of anthroposcopic and anthropometric estimates of physique in Belgian boys followed longitudinally from 13 to 18 years of age
The stability of physique determined by the anthroposcopic 'Atlas' technique and the anthropometric Health-Carter method was examined in a sample of 210 healthy Belgian schoolboys studied longitudinally at yearly intervals from 13 to 18 years of age. The two rating systems were also compared. Results indicate that components of the same type in the two methods do not measure the same underlying factors, particularly for mesomorphy (anthroposcopic…
Skeletal maturity and body size of teenage Belgian track and field athletes
Attained skeletal maturity (TW2 RUS method), skeletal maturity relative to chronological age, and body size of national-level Belgian track and field athletes 15 to 18 years of age were considered. Among the 47 male athletes, 29 (62%) were skeletally mature, while 15 (52%) of the 29 female athletes were skeletally mature. There appeared to be a predominance of skeletally mature individuals among male sprinters and jumpers, while a majority of fem…
Motor performance during adolescence and age thirty as related to age at peak height velocity
Relationships between motor performance, as measured by various fitness tests, and age at peak height velocity have been studied in a sample of 173 Flemish boys, measured yearly between +/- 13 and +/- 18 years and again as adults at 30 years of age. In addition to correlation studies, comparisons were made between boys with an early, average and late age at peak height velocity. To summarize the successive measurements during adolescence, a longi…
