Abstract: |
It has been postulated that genetic variation contributed more to sexually dimorphic variation than environmental or cultural factors. Moreover, the study of sexual dimorphism includes the study of growth and of the factors that modify growth patterns. pg 22 Requirements for both protein and calories are higher during the adolescent growth spurt in well nourished population where the characteristic sigmoid curve of values for both attained height and weight makes its abrupt upward deflection. However, this pattern of growth and development may be altered so that both attained height and weight follow amorelinear and porlonged trajectory. Later attainment of adult body size and less explosive growht both tend to be more economical in terms of caloric requirements of the individual. pg 24 ...there is abdundant evidence that few if any new skeletal muscle fibers appear in human after the sixth month postpartum. pg 29 The skeletal grows more slowly, particularly in males, with respect to both appearance of ossification centers and epiphyseal growth and closure. Termination of epiphyseal growth in males may not occur until the second half of the third decade of life.
