Choose the correct answer from the options given below:

The correct answer is - 2) A, B, C, E Only

Key Points

• Using muscles effectively
  • Involves the efficient use of muscle groups to minimize fatigue and maximize performance.
  • Ensures that muscle actions align with biomechanical principles for better movement outcomes.
• Taking consideration of line of gravity
  • The line of gravity refers to the vertical line passing through the center of mass, essential for maintaining balance and stability.
  • Understanding this concept helps in optimizing posture and movement efficiency.
• Appropriateness of posture
  • Good posture is crucial for minimizing strain on the musculoskeletal system.
  • Proper alignment of body segments enhances stability and performance.
• Using rhythm and momentum
  • Rhythm and momentum are used to facilitate smooth and efficient movement patterns.
  • Helps in conserving energy and improving movement fluidity.

Additional Information

• Law of margins
  • This is not a recognized principle in biomechanics.
  • Instead, biomechanics focuses on laws like Newton's laws of motion which explain the relationship between a body and the forces acting upon it.
• Newton's Laws of Motion
  • First Law (Inertia): A body remains at rest or in uniform motion unless acted upon by an external force.
  • Second Law (F=ma): The force acting on an object is equal to the mass of that object times its acceleration.
  • Third Law (Action-Reaction): For every action, there is an equal and opposite reaction.
