Muscle and Tendon Injuries Overview

Muscle Injuries

• Muscle Strain: Overstretching or tearing of muscle fibers.
  • Causes: Sudden forceful contraction, repetitive use.
  • Symptoms: Pain, swelling, bruising, weakness.
  • Grading:
    • Grade 1: Minor stretch, minimal loss of strength and function.
    • Grade 2: Partial tear, moderate loss of strength and function.
    • Grade 3: Complete tear, significant loss of strength and function.
  • Common Sites: Hamstrings, quadriceps, calf muscles, back muscles.
  • Risk Factors: Lack of flexibility, muscle imbalances, poor conditioning.
• Muscle Tear: Partial or complete tearing of muscle fibers.
  • Causes: Sudden forceful contraction, high impact trauma.
  • Symptoms: Severe pain, swelling, bruising, inability to use muscle.

Tendon Injuries

• Tendinitis: Inflammation of a tendon, often from overuse.
  • Causes: Repetitive motion, poor form, sudden increase in activity.
  • Symptoms: Pain, swelling, stiffness.
• Tendon Tears:
  • Partial Tears: Some tendon fibers damaged, but not completely ruptured.
  • Complete Tears: Tendon fully severed, often require surgical repair.
  • Causes: Sudden trauma or gradual degeneration.
  • Recovery: Involves rest, physical therapy, and sometimes surgery.
• Bursitis: Inflammation of fluid-filled bursa sacs cushioning joints.
  • Common Sites: Shoulder, elbow, hip, knee.
  • Causes: Repetitive motion, direct trauma, underlying conditions like arthritis.
  • Symptoms: Pain, swelling, stiffness, decreased range of motion.

Preventing Muscle and Tendon Injuries

• Proper Warm-up and Cool-down: Helps increase blood flow and prepare muscles and tendons.
• Gradually Increase Activity Levels: Avoid sudden increases in activity to prevent excessive strain.
• Strength Training: Builds strength in muscles and tendons. Focus on exercises specific to activities and muscle groups.
• Flexibility and Mobility Work: Improves flexibility in muscles and mobility in joints.
• Proper Technique and Form: Reduces strain on muscles and tendons. Seek guidance from a coach or trainer.
• Cross-Training: Varies activities to avoid overuse of the same muscle groups.
• Adequate Rest and Recovery: Allows muscles and tendons to recover between workouts. Prioritize sleep and stress management.
• Maintain a Healthy Weight: Reduces the load and strain on the musculoskeletal system.

Strength Training Exercises for Injury Prevention

• Hamstrings:
  • Nordic hamstring curls
  • Deadlifts
  • Leg curls
  • Glute bridges
• Quadriceps:
  • Squats
  • Lunges
  • Step-ups
  • Wall sits
• Calf Muscles:
  • Calf raises (seated & standing)
  • Jump training
  • Heel drops
• Rotator Cuff:
  • Shoulder external rotation
  • Rear delt flyes
  • Face pulls
  • Band pull-aparts
• Core:
  • Planks (front, side, reverse)
  • Dead bugs
  • Pallof presses
  • Wood chops
• General Lower Body Strength:
  • Hip thrusts
  • Step-ups
  • Lateral lunges
  • Single-leg RDLs
