Question

What are the short term effects on the skeletal system during exercise?

And that doesnt mean muscles - It means Joints and anything to do with the BONES THEMSELVES...

Answer 1

I do alot of running and i know it puts pressure on my joints, especially my hip, but normally just running on it makes it better anyway I think most of the effects of exercise on the skeletal system are only short term And by doing nothing i think it can still put pressure on the joints So in my opinion exercise is the better option because atleast it's keeping the rest of your body healthy

Answer 2

Cortisol (produced in parallel with Adrenaline) activates OSTEOCLASTS, which strip calcium & phosphorus from the whole skeletal system. (this provides a 'pool' of available minerals for use in reinforcing the sites that need it most. Meanwhile, stresses and vibrations 'target' OSTEOBLAST activity towards the most heavily loaded areas of the skeleton, and of each bone. Those parts are selectively reinforced. (that's why sports players show adaptation to their sport; for example, heavier bone in the dominant racket hand, etc.) In sedentary people (ie the population generally), the daily production of Cortisol (in response to stressful events) will cause bone demineralisation, but the 'available' minerals are disposed of, because there are insufficient local bone stresses to 'target' sites for reinforcement. (the sedentary nature of 'normal' life is the main cause of 'primary' (age-related) osteoporosis. Joints can suffer damage to the cartilage end-caps ('articular cartilage') if these come into contact with each other during the exercise. (leading, for example, to knee damage in runners) It is normal for this to happen, because the use of 'warmup' preparation is not properly understood, even by coaching and fitness professionals. A 'warmup' is not particularly useful for changing the temperature & viscosity of muscle tissue, or for raising the heart rate, or for improving motor signal transmission. (all these will change appropriately during the exercise itself, but are often cited as benefits of warming up) The most useful thing that a warmup does, is to stimulate the production of 'synovial fluid' within the joint. (small repeated movements agitate the joint capsule membrane ('synovium') which acts as a gland, producing more fluid) If the production of fluid is sufficient, the articular cartilages will be constantly separated by a layer of the lubricating fluid, and will avoid damage. If the warmup is omitted or incorrectly performed, the correct pressure will only be achieved after 10 - 15 minutes of very damaging exercise have been performed. The fluid also soaks into the articular cartilages, making them soft and springy so that they can cope better with any jarring that does cause contact (eg stepping on a loose stone). A third function of the fluid is to provide nutrients and raw materials for repair, to the internal parts of the joint (which have no blood supply).

Answer 4

short term vibration from exercise can be counter productive, as in causing hairline fractures that will gradually get worse ans worse until they develop into a more serious injury.

Answer 5

I don't think there are any... as long as you consume calcium daily...
