Muscle ache caused by exercise is a very common injury experience for people who participate in sports. Generally speaking, muscle soreness caused by exercise can be divided into acute muscle soreness and chronic (delayed muscle soreness). Acute muscle soreness is different from muscle strain, but refers to the pain caused by temporary muscle ischemia. This kind of pain will only appear under the condition of intense or long-term muscle activity, and will disappear as soon as muscle activity is over. Usually, acute muscle soreness will mix with muscle stiffness.
