Why do movement generation answers lose marks in IB SEHS?

In IB SEHS, examiners award marks for specific, observable statements: joint action, muscle role, contraction type, and often neural control. Students lose marks when they describe movement in everyday language that can’t be tied to the markscheme. Another big issue is mixing definitions (like eccentric vs concentric) or leaving out the key feature of muscle length change. Answers also drop marks when the example is not anchored to a joint or phase of movement. Finally, many students describe muscles but never explain control or stability, where antagonists and eccentric contractions matter. The fix is simple: write less, but write more precisely.

How detailed should contraction type explanations be for IB SEHS exams?

You don’t need a paragraph for each contraction type, but you do need the correct defining feature. In IB SEHS, a high-quality line usually includes: the contraction name, what happens to muscle length, and what happens at the joint. If you add a quick example (like lowering a dumbbell for eccentric), you strengthen clarity without adding fluff. Avoid describing only the movement (“going down”) because the markscheme wants the muscle behavior. Also avoid adding unrelated physiology unless the question asks for it. The best answers are compact, accurate, and applied.

How can I get better at applying movement generation to sport examples in IB SEHS?

Start by choosing one movement you can always use, like a vertical jump, sprint start, or throw. In IB SEHS, application improves when you consistently name the joint action (hip extension, knee extension, plantarflexion) and match it to agonist muscles. Then add one sentence on the antagonist’s role in control or deceleration, because that’s a common mark opportunity. After that, sprinkle in neural control: motor unit recruitment or firing rate to justify force changes. Practice this structure using the RevisionDojo Questionbank so you’re training exam execution, not just understanding. With repetition, your examples become quick “templates” you can adapt to almost any prompt.
