Before I started my studies I am sure I heard that exercise is good for the bones. Now that I am on the section about bones it doesn’t really say anything about bones and exercise. Can you help me better understand this?
Kelly, good afternoon I hope you are well and having a great Thursday. With regard to your question, rest assured that as you continue with the remainder of the modules we will go into more details of the training effect on the entire body including the bones. Until that time consider the following. Bone remodeling is a process where the adult skeleton undergoes a continuous turnover whereby old bone is reabsorbed by osteoclasts and new bone is formed by osteoblasts. Osteoclasts are cell types that degrade bone and its protein components by releasing calcium from bone into circulation, where calcium can either remain, or be excreted in urine and feces, while osteoblasts are cell types that synthesizes new bone. A number of hormones, including thyroid, parathyroid, sex hormones, Vitamin D3, and others exert their influence on bone remodeling and interact with immune system proteins such a interleukin-6 (IL-6). Their production in turn is inhibited by estrogen and testosterone, so there is evidence that the balance of sex hormones and interleukin-6 affects trabecular bone loss. Therefore if you can continue to add weight bearing exercise to your daily life, you can continue this rebuilding process.
We hope this helps. Take care and have a great afternoon.
