“…The values for h 2 reported by Bergman et al are also similar to the results obtained in the present study: age at peak velocity (0.78), adult size (0.77), and peak height velocity (0.76). Bergman and Goracy (1984) analysed the genetic basis of age at peak velocity for several body traits in the same material. However, they used a graphical interpolation technique to determine age at peak velocity developed by Bielicki and Welon (1973), and worked on a slightly bigger sample size than in the present study (51 MZ and 52 DZ pairs).…”

Genetic aspects of the pattern of growth and of short-term variations in growth velocity for height were studied in a sample of 44 MZ and 42 DZ twin pairs from the Wroclaw Longitudinal Twin Study. The data consists of serial measurements of height, taken between 8.5 years of age and adulthood. The intra-pair resemblance of the pattern of attained height was quantified by means of the average Euclidean distance coefficient and the coefficient of shape difference, calculated on the raw height-for-age data. Comparison of these resemblance coefficients between the two types of twins indicated that the growth curves of MZ twins are closer to each other, and more similar in shape, than those of DZ twins. The shape of the growth curve was further characterized by a set of biological parameters, derived from Preece Baines model I (PB) fitted to each subject's serial growth data. Genetic analysis of these parameters, according to the model of Christian, Won Kang and Norton (1974), revealed a strong genetic component in the variance of size at particular milestones in the growth process (height at take-off, at peak velocity and at adulthood), and also in the timing of the growth process (age at take-off and at peak velocity). Height velocity at take-off and peak height velocity were also strongly genetically determined. Finally, short-term variations in growth velocity were analysed on the basis of the profiles of the residuals, obtained by the PB fits to each subject's serial measurements of height. Resemblance coefficients were calculated for the profiles of residuals. The results revealed a significantly greater similarity of profile shapes of the residuals in MZ twins than in DZ twins, strongly suggesting that there is a genetic component in the short-term variations of growth velocity.

“…WHO (1976) recommended the use of children's growth data as one of the best indices of the health and nutritional status of a community. Body size at a given age is one of several characteristics of physical growth for which variation within or between populations is both genetic and environmental (Fischbein, 1977;Bergman and Goracy, 1984). Significant contributions to this variation are the adequacy of nutrition and the state of hygiene.…”

Somatic comparisons at four ages of South Korean females and females of other Asian groups

1999

Somatic data were collected during April 1997 on 156 females ages 6, 9, 13, and 15 years, residing in urban Pusan, South Korea, and on 158 age peers residing in rural regions surrounding the city. Comparisons were made between urban and rural groups for measures of body size and form, skinfold thicknesses, the body mass index (BMI), and estimated arm muscle area (ARM). Age at menarche was retrospectively reported by the 13‐ and 15‐year‐olds. The data were analyzed in 2 (urban‐rural) × 3 (age) analyses of variance with an alpha level of P < 0.05. Age differences were evident for all dimensions. A significant main effect for urban–rural differences was found for stature, lower limb height, upper limb height, shoulder width, hip width, triceps skinfold, ARM, skelic index, and the trunk width index. Regardless of age, urban children were larger than rural children. Similar means were obtained for the BMI in urban and rural girls. Age at menarche was consistent with recent results; however, the rural sample (12.4 years) was significantly earlier than the urban sample (13.1 years). Compared with data collected four decades ago, present‐day 6‐, 9‐, 13‐, and 15‐year‐old females are taller and heavier at every age, indicating secular gains. Pusan females are similar in stature to age peers in Taiwan, Japan, and Hong Kong, and taller than the Chinese. Am. J. Hum. Biol. 11:735–744, 1999. © 1999 Wiley‐Liss, Inc.

“…Further, in general both performances and body sizes seemed to have almost the same degree of similarity. The growth patterns in stature and body mass during adolescence, characterized by several biological parameters such as age at peak velocity, have been reported to be more similar in MZ than in DZ twins (Fischbein, 1977;Sharma, 1983;Bergman and Goracy, 1984;Hauspie et al, 1994), or within family than between families (Hauspie et al, 1982;Byard et al, 1993). Considering that these data have been considered the evidence for the presence of the genetic effect, the comparable degree of similarity in performance curves of MZ to that in growth curves would suggest that genetic control works also in determining the developmental pattern of running performances.…”

“…High heritability estimated at a certain point in time does not guarantee equally high heritability at later points in time. Although many studies examining the pattern of whole-body growth by using stature and body mass found a significant contribution of genotype (Fischbein, 1977;Hauspie et al, 1982Hauspie et al, , 1994Sharma, 1983;Bergman and Goracy, 1984;Byard et al, 1993), there has been no genetic study, to our knowledge, on the development in physical performances on a longitudinal basis. In the present study, therefore, we compared within-pair similarity in the shape of developmental curves of running performances of MZ twins with that of genetically unrelated pairs in order to assess the genetic effect on the age-related change in running performances.…”

Similar age-related changes in running performance and growth in adolescent monozygotic twins

The purpose of this study was to assess the similarities in the pattern of age-related change in the running performance and physical growth in adolescent monozygotic (MZ) twins. The total sample was 70 boys and 100 girls, including 14 pairs of male and 25 pairs of female MZ twins. Performance of the 50 m dash and endurance run (1,500 m for boys and 1,000 m for girls), and stature and body mass were measured longitudinally at yearly intervals from 12 to 17 years of age. The within-pair resemblance was compared between MZ twin pairs (MZ) and control pairs (CP), which were selected from the other subjects matched with each member of MZ for the initial values. The within-pair similarity in performance and growth curves was quantified by an average Euclidean distance coefficient (d(jk)) and a coefficient of shape differences (z(jk)) and a graphical analysis on the d(jk)-z(jk) coordinate. The time relationship between two curves was assessed by the arrangement of the sign of within-pair differences (number of runs, NR). Within-pair differences of measured value at the first and the last measurements were also examined. MZ generally showed smaller d(jk) and z(jk), clustering around the origin on the d(jk)-z(jk) coordinate. Frequency of observation of NR = 1, which means one member of a pair had consistently larger values than the other, tended to be lower in MZ in performance items. Within-pair differences in the last measurements were generally greater in CP. It was concluded that MZ twins have meaningful similarities in the pattern of age-related changes in running performances and physical growth during adolescence. Am. J. Hum. Biol. 12:623-632, 2000.
