Muscle pain: acute pain and chronic pain. Acute pain: muscle pain occurs during exercise or in a short time after exercise. Acute soreness is related to the interruption of blood flow caused by muscle exertion. In the case of ischemia, metabolites can not be eliminated, but accumulate in muscles, thus stimulating pain receptors. You will fully recover in about a minute after you stop exercising. Chronic soreness: Chronic muscle soreness often occurs between 24 and 48 hours after training. The degree of chronic muscle soreness is related to the form of muscle contraction. Centrifugal contraction is the most likely to form chronic muscle soreness, while isotonic contraction is the least significant. When chronic muscle aches, muscle strength drops obviously.

It's usually good to take a day off to practice. Go to the gym and ask the coach.

In addition, you must warm up for more than ten minutes before playing equipment in the gym. It is best to relax your muscles after exercise. Ok, ask the fitness instructor specifically. Or go to the gym or something and read the essence post.
