Today’s Objectives List and describe some activity-related physical injuries. List some guidelines for preventing injury during physical activity. Explain how to apply the RICE formula for treating physical injuries. List three biomechanical rules for preventing injury.

Minor Activity-Related Injuries Cuts, scrapes, and bruises Blisters Sprain: injury to a ligament Strain: injury to a tendon or muscle

Major Activity-Related Injuries Bone breaks Joint dislocations Concussions

Overuse Injury and Microtrauma Overuse injury results from the repetition of movements that place wear and tear on your body (e.g., blisters, tendinitis). Microtrauma is a injury to your body that you don’t feel, but with repeated movements the symptoms of damage eventually appear (e.g., backaches).

Guidelines for Preventing Injury Start slowly. Listen to your body. Be fit! Use moderation. Dress properly. Avoid risky exercises.

RICE Formula R = Rest I = Ice C= Compression E = Elevation

Biomechanical Rules for Preventing Injury Avoid movements that stretch your ligaments. Avoid movements that twist your joints or force them to move in other ways for which they were not designed (e.g., hyperflexion and extension). Avoid movements that use your body’s levers improperly. Balance your muscle development on both sides of your joints so that all of your muscles develop properly.

Group Activity 1 Read the Taking Charge feature: Improving Performance Skills Pg. 131. Answer the For Discussion questions. Be prepared to discuss your answers with the class.

Taking Charge: Performance Skills For Discussion: What advice would you give Zack for choosing a sport? Once he makes his choices, what steps could he take to improve his performance skills? Who could he talk to for help? Zack knew that he needed to practice but wasn’t sure exactly what to practice. What practice advice would you give him?

Guidelines for Building Performance Skills Get good instruction. Practice. Practice all skills, not just those that you already do well. At first, don’t worry about details. Avoid competing while learning a skill. Think positively. Choose an activity that matches your skill-related fitness. Consider mental practice.
