How to answer it
Movement Analysis: Overhead Dumbbell Extension
This question assesses your ability to apply knowledge of applied anatomy and movement analysis (AO2) to a practical sporting scenario (a resistance training exercise).
- Identifying the specific joint action at a hinge joint (elbow) during a movement.
- Distinguishing between types of isotonic muscle contraction (concentric vs. eccentric).
• Position A: Starting phase – The arm is bent backwards at the elbow behind the head (elbow is in flexion).
• Position B: Finishing phase – The arm is pushed upwards, straightening the arm overhead (elbow is in full extension).
Joint Action at the Elbow
"Identify the joint action taking place at the elbow as they move the weight from A to B."
✅ Correct Answer
Extension
Award 1 mark for correctly identifying "Extension".
💡 Key Knowledge
- Flexion: Decreasing the angle at a joint (bending the arm).
- Extension: Increasing the angle at a joint (straightening the arm).
- Moving from A to B increases the angle at the hinge joint of the elbow from roughly 45°–60° to 180°.
🧠 Exam Technique
- Follow the arrow/direction: Always check whether the question asks for A to B or B to A.
- Look only at the specified joint: the question asks specifically about the elbow , not the shoulder.
❌ Common Errors
- Confusing flexion and extension: Writing "Flexion" because position A shows a flexed elbow. The question asks for the movement taking place.
- Naming the joint type: Writing "hinge joint" instead of the action occurring at the joint.
Type of Muscle Contraction
"Identify the type of isotonic muscle contraction that is taking place at the elbow as they move the weight from A to B."
✅ Correct Answer
Concentric
Award 1 mark for correctly naming "Concentric".
💡 Key Knowledge
- Agonist muscle: The triceps brachii is the prime mover (agonist) responsible for elbow extension.
- Concentric contraction: Muscle shortens under tension as it overcomes resistance (lifting phase from A to B).
- Eccentric contraction: Muscle lengthens under tension (controlling weight on the way down from B to A).
🧠 Exam Technique
- The question already specifies isotonic. Do not write "isometric" (where muscle length does not change).
- Your only two choices for isotonic are concentric or eccentric. Since work is done against gravity (upward drive), it is concentric.
❌ Common Errors
- Writing "Isometric" – this is not a type of isotonic contraction, and movement is clearly occurring.
- Writing "Eccentric" – this would only be correct if moving from B down to A (lowering under control).
- Just writing "Isotonic" – the question asks for the type of isotonic contraction.
