What are the functions of osteoblasts and osteoclasts

Osteoclasts are responsible for resorbing, or breaking down, bone matrix. A balance between bone production and bone resorption is necessary for remodeling and renewing your skeleton. Osteocytes are mature osteoblasts that have become trapped within the very bone matrix they produced.

no, because those are both different running competitions. while distance runners train their legs and their lungs to run long amounts of time, the sprinters are training their legs and their lungs to give all they have in the little amount of area they need to cover. the brain also plays a huge part in all of this.

the brain is the only thing in your body that sends messages to your body telling you to run. if you are a long distance runner and you have the mind set of a sprinter, you will not get anywhere. if you have a long distance mind set and you have to run 200m in 20 seconds then you will not make it in time.
