Summary
Regular impact exercise in premenopausal women positively affects bone health by lowering parathormone (PTH) levels, suggesting increased calcium incorporation into bone. However, it did not significantly alter bone turnover markers over 12 months.
Area of Science:
- Exercise Physiology
- Bone Metabolism
- Endocrinology
Background:
- Long-term effects of high-impact exercise on bone health are not fully understood.
- Investigating the impact of exercise on calciotropic hormones and bone turnover is crucial for bone health management.
Purpose of the Study:
- To determine the long-term effects of high-impact exercise on bone turnover and calciotropic hormones in premenopausal women.
- To assess the relationship between impact exercise, parathormone levels, and bone health indicators.
Main Methods:
- A 12-month randomized controlled trial involving 120 premenopausal women (age 35-40).
- Participants were assigned to a high-impact exercise group or a control group.
- Bone turnover markers and calciotropic hormones were analyzed at baseline, 6, and 12 months.
Main Results:
- Twelve months of impact exercise did not affect bone turnover markers (PINP, TRACP5b).
- Serum basal parathormone (PTH) levels significantly decreased in the exercise group compared to the control group.
- The reduction in PTH was dose-dependent, correlating with the number of daily impacts.
Conclusions:
- Regular impact exercise demonstrates positive osteogenic effects, potentially through lowered basal PTH levels.
- Continuous training is necessary to achieve sustained bone benefits, as impact exercise alone did not cause persistent alterations in bone turnover markers.
- Lowered basal PTH may indicate increased calcium incorporation into bone, contributing to osteogenic effects.

01:17Hormones 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...

01:29Bone 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...

01:40Bone 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.
01:31Essential 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...

01:25Role 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...

01:31Osteoclasts in Bone Remodeling
Osteoclasts are cells responsible for bone resorption and remodeling. They originate from hematopoietic progenitor cells present in the bone marrow. Numerous progenitor cells fuse to form multinucleated cells, each with 10-20 nuclei. A single osteoclast has a diameter of 150 to 200 µM. These cells have ruffled borders that break down the underlying bone tissue and release minerals such as calcium into the blood in bone resorption. Osteoclasts cling to bones with their ruffled edges during bone...
