The dynamics of bone structure development during pubertal growth.
The pubertal growth spurt is a time of rapid changes in bone length, mass and structure, followed by the cessation of longitudinal growth. The two best studied anatomical areas in this respect are the metaphyses and the diaphyses of peripheral long bones. A model is presented here in which the speed of longitudinal growth and the resulting age gradient in metaphyseal bone are key factors in exp...
متن کاملGrowth, pubertal development, skeletal maturation and bone mass acquisition in athletes.
The genetic potentials for growth can be fully expressed only under favourable environmental conditions. Excessive physical training may negatively affect growth, especially during puberty. Sports that require a strict control of energy input in the presence of a high energy output are of particular concern. In gymnastics, a different pattern in skeletal maturation was observed, leading to an a...
متن کاملBone mineral homeostasis, bone growth, and mineralisation during years of pubertal growth: a unifying concept.
Serum calcium, magnesium proteins, phosphate, and immunoparathyroid hormone were measured in 338 normal children and adolescents aged between 7 and 20 years and in 123 normal adults aged between 21 and 50 years. Protein corrected serum calcium and magnesium remained stable throughout the study. Despite hyperphosphataemia protein corrected calcium exceeded the concentrations of normal adults. Se...
متن کاملPhysical activity increases bone mass during growth
BACKGROUND The incidence of fragility fractures has increased during the last half of the 1990's. One important determinant of fractures is the bone mineral content (BMC) or bone mineral density (BMD), the amount of mineralised bone. If we could increase peak bone mass (the highest value of BMC reached during life) and/or decrease the age-related bone loss, we could possibly improve the skeleta...
متن کاملEnvironmental factors influencing growth and pubertal development.
Postnatal growth is based on hereditary signals and environmental factors in a complex regulatory network. Each factor must be in an optimal state for normal growth of the child. Fetal conditions may also have consequences on postnatal height. Intrauterine growth retardation can be recovered postnatally, although postnatal growth remains depressed in about one-third of cases. After birth, the e...
