How can competitive sports harm your body? By Ana Worthington Overuse injuries • Year round sports players who don’t give injuries proper recovery time • Key Concept- Swelling: – Body’s first step toward healing – Movement of fluid and white blood cells to injured area – Edema- fluid that has accumulated outside joint capsule – Effusion- fluid accumulated inside joint capsule – Red and hot- from increase blood flow Tendonitis • Tendons (thick fibrous cord that attaches muscle to bone) can fray like rope with repetitive motion and tendon change causes inflammatory response. • Most common: shoulder, elbow, wrists, knees, heels • Symptoms: pain, rash, swelling • Diagnosis: creaky sound when moving tendon (tendon sheath has become thicker: irritation caused fibrous tissues to form), imaging tests reveal swelling Chondromalacia patellae (runners knee) • Key Concept: Kneecap sits in patella groove at the front of the knee on the femur and is lined with very thick cartilage for smooth movement. Causes: patella cannot move correctly and causes extra stress on cartilage - muscle weakness = more weight on patella – muscle is weak or tight on one side = cause patella to shift and create friction – foot positioning = knees roll forward and increase pressure on patella – Anatomy = issue with patella groove and cause friction Symptoms: pain around knee (especially when running, lunging, stairs) Treatments: Strengthening muscles (quad) that will take relieve stress from patella, stretches to reduce muscle tightness Why this topic is special to me: Works Cited • Kay Cahill Allison.
