Which of the following is not one of the important effects of stretching before a workout? a. regulate breathing b. gently lengthens and strengthens muscles c. prevents muscles from tightening during exercise d. develop overall flexibility

Explanation:

Stretching comprehend low intensity exercises through which muscles and tendons are intentionally stretched to improve elasticity and get a comfortable state. This practice is made before and after workouts: before, to give an "introduction" to muscles about the next intensity they'll experience; after exercise, to release tensions and relax muscles from contractions during the previous workout; by stretching we can also improve the range of motion.

Another reason that why we should stretch before and after exercises is to prevent muscles cramps or tightening, because if the muscles are not prepare to the intensity, they could response in a negative way.

On the other hand, it haven't been demonstrated that stretching influence directly and improve cardiorespiratory system. To regulate breathing we don't necessarily have to stretch, we can just breath slower, but more concentrated.
