Physical Education: Muscular Involvement

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:
1. Identify the movement or skill
2. Determine the joints involved and their movements
3. Identify the agonist and antagonist muscles involved
4. 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

Description

Learn about the role of agonist and antagonist muscles in physical education, and how to analyze movement patterns. Understand the concept of movement analysis and its application in sports like tennis and soccer.
