Study Notes
Muscular Involvement in Physical Education
Agonist Muscles
- Also known as prime movers, these muscles are responsible for producing the primary movement or action
- Contract to generate force and movement
- Examples:
- Bicep brachii in elbow flexion
- Quadriceps in knee extension
- Deltoid in shoulder flexion
Antagonist Muscles
- Oppose the action of agonist muscles
- Contract to slow or control the movement
- Examples:
- Tricep brachii in elbow flexion (opposes bicep brachii)
- Hamstrings in knee extension (opposes quadriceps)
- Teres minor in shoulder flexion (opposes deltoid)
Movement Analysis
- Involves breaking down a movement or skill into its component parts to understand the muscular involvement
- Steps:
- Identify the movement or skill
- Determine the joints involved and their movements
- Identify the agonist and antagonist muscles involved
- Analyze the movement pattern and muscle activation
- Examples:
- Analyzing a tennis serve: identifying the joints involved (shoulder, elbow, wrist), the muscles involved (agonist: deltoid, tricep brachii; antagonist: teres minor, bicep brachii), and the movement pattern
- Analyzing a soccer kick: identifying the joints involved (hip, knee, ankle), the muscles involved (agonist: quadriceps, hamstrings; antagonist: gluteus maximus, tibialis anterior), and the movement pattern
