What differentiates extension from hyperextension? a. extension bends joints in the opposite direction as hyperextension. b. extension straightens a joint, and hyperextension bends it but in the opposite direction from flexion. c. hyperextension straightens a joint, and extension bends it in the opposite direction from flexion. d. both bend joints, but extension can be damaging.

B. Extension straightens a joint, and hyperextension bends it but in the opposite direction from flexion.

Explanation:

Stretching and overexertion are terms that refer to body movements. Extension refers to movement in the sagittal plane, in which two body segments (proximal and distal) move away from each other, at which point a joint is straightened. Hyperextension, on the other hand, occurs when the extension movement exceeds the anatomical position, or beyond its normal capacity, at which point a joint is bent in the opposite direction to flexion.

i think it would be b the increase in body temp

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.
