Physical Activity and Injury OBJECTIVES: List and describe some activity related physical injuries. List some guidelines for preventing injuries during physical activity. Explain how to apply the RICE formula to the treatment of physical injuries. Identify different types of risky exercises. VOCABULARY YOU SHOULD KNOW: Biomechanical principles Ligament Micro Trauma Overuse injury Side Stitch Tendon COMMON INJURIES ?? What are they in your sport?? blisters cuts dislocations strains sprains bruises fractures COMMON INJURIES skin feet Leg muscles ankles knees OVERUSE INJURY Caused by repetitive movement. Blister most common Shinsplints Runners Heel COMMON INJURIES “Side Stitch” Pain in lower abdomen due to vigorous activity. Press heel of hand while bending forward or backward. Micro= small Microtrauma: trauma = injury: Often won’t show up on x-ray. “overuse” PREVENTING INJURIES How many bones? Held together how??? Muscle contraction = body movement. Biomechanical principles= 1) Don’t force in direction not designed to go! Muscle contraction = TENDONS VS LIGAMENTS Preventing Injuries Biomechanical principles= 1) Don’t force in direction not designed to go! 2) Movement shouldn’t over stress bones, tendons, ligaments or muscles. 3) Balance muscle development. (“antagonistic”) PREVENTION GUIDELINES: 1) Start Slowly 2) Listen to body 3) Warm-up/Cool downs 4) Be Fit 5) Moderation 6) Dress Appropriately R.I.C.E R= REST I= ICE C= COMPRESSION E= ELEVATION RISKY EXERCISES/MOVEMENTS Goes against biomechanical principles Hyperflexion vs hyperextension Hyper = “too much” Hyperflexion is using joints in a way not intended. Flexion = “to bend” RISKY EXERCISES TO AVOID AVOID: HyperEXTENSION Opposite of “flexion” EXERCISES TO AVOID: Twisting motion: Friction = wear n tear on joints/tissue. ??
