Final answer:
It's true that warming up muscles before stretching is important to prevent injuries like muscle strain and tendinitis, since a warm-up increases blood flow and prepares muscles for activity.
Step-by-step explanation:
True. It is best to warm up your muscles before stretching. A warm-up is essential in preparing your muscles and tendons for exercise by gradually increasing the blood flow and heart rate, thus making your muscles less prone to injury. This preparation is important to avoid muscle injuries such as strains or tendinitis, which are caused by muscle or tendon irritation from inadequate warm-up.
For instance, jogging slowly before running or engaging in a soccer match is a recommended way to warm up.Stretching the muscles after they are adequately warmed up is important as well, preventing injury by pulling on the muscle fibers, which increases blood flow to the muscles involved.
