El ejercicio durante el crecimiento y la densidad mineral ósea y las fracturas en la vejez
Lancet (London, England)
|June 7, 2000
Resumen
Los futbolistas no mantienen una alta densidad mineral ósea (DMO) después de la jubilación. Este estudio sugiere que los beneficios de la masa ósea máxima no previenen las fracturas en la vejez.
Área de la Ciencia:
- Deportes Ciencias Ciencias Ciencias Deportivas
- Gerontología Gerontología.
- La ortopedia es la ortopedia.
Sus antecedentes:
- La actividad física durante el crecimiento es crucial para el desarrollo óseo.
- Los beneficios a largo plazo del ejercicio sobre la densidad mineral ósea (DMO) y la prevención de fracturas en poblaciones de edad avanzada requieren más investigación.
Objetivo del estudio:
- Para determinar si la alta densidad mineral ósea (DMO) alcanzada durante una carrera en el fútbol se mantiene en la vejez.
- Para evaluar si un historial de juego de fútbol influye en la frecuencia de fracturas en la vida posterior.
Principales métodos:
- Diseño de estudio transversal. diseño de estudio transversal.
- Inclusión de jugadores de fútbol jubilados.
- Evaluación de la densidad mineral ósea (DMO) en la vejez.
- Análisis de la frecuencia de fracturas en la cohorte del estudio.
Principales resultados:
- Los jugadores de fútbol jubilados no exhibieron una mayor densidad mineral ósea (DMO) en comparación con las normas de la población general para la vejez.
- La frecuencia de las fracturas observadas en los jugadores de fútbol jubilados no fue menor que la prevista para su grupo de edad.
- Los beneficios esqueléticos asociados con la participación en el fútbol durante el crecimiento parecen disminuir o no se mantienen en la vejez.
Conclusiones:
- La alta densidad mineral ósea (DMO) alcanzada a través del ejercicio intenso de la infancia y la adolescencia puede no ser un factor de protección de por vida.
- Las recomendaciones para el ejercicio durante el crecimiento deben considerar el mantenimiento de la salud esquelética a largo plazo más allá de la masa ósea pico.
- Se necesita más investigación para identificar modalidades y duraciones de ejercicio que confieran protección duradera contra la osteoporosis y las fracturas en la vejez.

Bone Remodeling
Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.
Bone Disorders
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Essential Minerals for Bone Health
The minerals contained in all of the food we consume are essential for our organ systems. However, certain essential minerals, such as calcium, phosphorus, magnesium, manganese, and fluoride, largely affect bone health.
Calcium and Phosphorus
Calcium is a critical component of bones, especially in the form of calcium phosphate and calcium carbonate. Since the body cannot make calcium, it must be obtained from the diet. However, calcium cannot be absorbed from the small intestine without...

Hormones and Bone Tissue
The endocrine system produces and secretes hormones, which interact with the skeletal system. These hormones control bone growth, maintain bone once it is formed, and remodel it.
Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...

Changes in the Appendicular Skeleton with Age
The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...

Role of Vitamins in Maintaining Bone Health
The growth and maintenance of bone are regulated by a combination of nutritional factors, including vitamins, such as vitamin A, B12, C, D, and K.
Vitamin A
Vitamin A is involved in the process of bone remodeling. Retinoic acid, the active metabolite of Vitamin A, has nuclear receptors in osteoblasts and osteoclasts, which are involved in bone remodeling.
Vitamin B12
Vitamin B12 acts as a cofactor during the formation of osteoblast-related proteins, such as osteocalcin. Vitamin B12 plays a role...
