For the knee joint. a. Name the articulating bones b. Name the main agonist for knee extension
a. Femur and Tibia b. Quads
1 of 8
Explain the term antagonistic pair using the elbow joint as an example
Muscles work in pairs because they can only pull. The agonist causes the movement and the antagonist relaxes. E.g. during flexion the bicep is the agonist and the tricep is the antagonist
2 of 8
Explain why the tricep muscle will perform 2 types of muscle contraction during a press up
During the upward phase it shortens under tension so is concentric. On the downward phase it lengthens under tension so is eccentric
3 of 8
There are different types of muscular contraction. Compare isotonic and isometric. Compare concentric and eccentric
Isotonic means movement, isometric is no movement. Concentric shortens under tension. Eccentric lengthens under tension
4 of 8
Name the joint type at the ankle. When you point your toes what is the joint action and the main agonist
Hinge joint. Plantar flexion. Gastrocnemius

What type of joint is the shoulder. Name the articulating bones. In a badminton underarm serve name the movement and agonist
Ball and socket. Humerus and Scapula. Flexion. Deltoid (anterior)

When doing the slow downward phase of a squat. Name the movement at the hip. What is the muscular action? What is the agonist muscle
Flexion. Eccentric. Gluteus maximus (Gluteals)
