Summary
Adolescent exercise guidelines, including resistance and impact activities, can increase peak bone mass (PBM) and reduce fracture risk later in life. These recommendations aim to improve long-term bone health and public health outcomes.
Area of Science:
- Exercise Physiology
- Bone Health
- Adolescent Health
Background:
- Adolescent bone mineral density is crucial for preventing age-related fractures.
- Peak bone mass (PBM) achieved during youth significantly impacts future skeletal health.
- Osteoporosis and fracture risk in older age are linked to adolescent bone development.
Purpose of the Study:
- To develop evidence-based exercise guidelines for adolescents.
- To enhance peak bone mass (PBM) in adolescents through targeted physical activity.
- To provide recommendations for increasing adolescent bone density and reducing future fracture risk.
Main Methods:
- Systematic review of research published since 2000.
- Identification and selection of 9 key questions (KQs) related to exercise and PBM.
- Literature review to define the effects of various exercises on adolescent bone health.
Main Results:
- Vigorous physical activity (VPA), including resistance and impact exercises for 5-6 months, effectively improves adolescent PBM.
- Recommended resistance exercise: 10-12 reps/set, 1-2 sets/region, 3 days/week, targeting large muscles.
- Recommended impact exercise: at least 50 jumps/min, 10 min/day, 2 days/week.
Conclusions:
- Developed exercise guidelines recommend 5-6 months of VPA with resistance and impact components.
- Implementation of these guidelines can lower future osteoporosis and fracture incidence.
- Improved adolescent bone health contributes to better public health in an aging society.

Bone Disorders
5.0K
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...

Hormones and Bone Tissue
3.6K
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...

Role of Vitamins in Maintaining Bone Health
4.8K
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...

Essential Minerals for Bone Health
5.8K
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...

Bone Remodeling
40.1K
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.

Changes in the Appendicular Skeleton with Age
3.3K
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...
