Agonist Muscles and Their Opponents

Agonist muscles and antagonist muscles are very important when we move our bodies.

Agonist Muscles: These are the main muscles that help us do a certain movement.

For example, when you do a bicep curl, your biceps are the agonist. They help bend your elbow.

Antagonist Muscles: These muscles work against the agonists.

In the bicep curl, after you bend your elbow, your triceps help to straighten it out. So, the triceps are the antagonist in this case.

Key Differences:

• Function:

  • Agonists start and keep the movement going.
  • Antagonists stop any movements from going too far and keep everything in control.

• Example: When you do a squat, your quadriceps (the agonist) make your knee straighten. At the same time, your hamstrings (the antagonist) help control this movement by working against it.

This teamwork between agonists and antagonists helps us stay balanced and move smoothly.
