Stretching - essential so you don't pull a muscle. Skill related to the activity - develop in a weak/important area of your sport. The cool down equally important for preventing injury disperses lactid acid to avoid muscle soreness/stiffness. lowers blood pressure. 10 of 12 Muscular System What are the 3 types of muscle injuries, define the sprain and how are they healed? Explain RICE. 11 of 12 Muscular System Muscle injuries Tear Pull Strain - in the joint where it has been moved beyond it's normal range of movement. They human body is able to rebuild + repair these fibres during rest. Rest - stop immediatly so no more damage is done. Ice- apply ice to the injury to reduce swelling. Compression - wrap a bandage around the injury to reduce swelling. Elevation - lift the injury so the blood flow slows down reducing swelling. 12 of 12
