Basic Movements - the Elbow

The hinge joint in the elbow is made up of the humerus, radius and ulna. The muscles used to move this joint are the biceps and triceps.

Football throw-in

  • During a throw-in in football, the triceps contract and shorten (concentric contraction) to straighten (extend) the arm.
  • The triceps are the prime mover (agonist) because their contraction moves the arm directly. But the biceps relax and extend (antagonist) to counteract (act against) this action.

Bicep curl

  • During a bicep curl, the biceps are the prime mover and contract concentrically to create flexion (bending the arm). The triceps relax and extend, which makes them the antagonist.

Basic Movements - the Knee

The hinge joint in the knee is made up of the femur, tibia and fibula. The muscles used to move this joint are the quadriceps and hamstrings.

Running or kicking

  • When running/kicking/standing/jumping/squatting, the quadriceps contract and shorten (concentric contraction) to straighten (extend) the leg out in front.
  • The quadriceps are the prime mover (agonist) because their contraction moves the leg directly.
  • But the hamstrings relax and extend (antagonist) to counteract (act against) this action.

Pushing off the floor

  • When pushing off the floor, the hamstrings are the prime mover as they contract and shorten (concentric contraction) to cause flexion at the knee (bending of the leg).
  • The quadriceps relax and extend, which makes them the antagonist.

Basic Movements - The Hip

The ball and socket joint in the hip is made up of the femur and pelvis. The muscles used to move this joint are the hip flexor and the gluteus maximus.

Running and kicking: part 1

  • During running/kicking/standing/jumping/squatting, the gluteus maximus contracts and shortens (concentric contraction) to extend the hip (push the hip forwards).

Running and kicking: part 2

  • During running/kicking/standing/jumping/squatting, (lifting the leg) the hip flexors contract and shorten (concentrically) to cause flexion at the hip. The hip flexors are the prime mover (agonist) because their contraction directly moves the hip. But the gluteus maximus relaxes and extends (antagonist) to counteract (act against) this action.
