IB Sports, exercise and health science (SEHS) SL Extended Essay Example

The student communicates a clear SEHS topic and keeps the investigation anchored to the comparison between active and passive warm-ups.

The student establishes a relevant research focus and maintains an overall line of discussion that connects to short-distance swimming.

The student uses a range of relevant sources and shows some awareness of how evidence from other contexts may or may not transfer to swimming.

The student's question is still broad and would be stronger if they defined the race distance, swimmer population, and exact performance measures.

The methodological basis is not explained clearly enough for a literature-based investigation, so the source selection does not feel systematic.

Some parts of the topic framing drift between different populations and contexts, which weakens precision.

The student demonstrates good general understanding of warm-up physiology and uses concepts such as muscle temperature, neuromuscular activation, fatigue, and post-activation potentiation appropriately.

The student includes relevant terminology from both physical and psychological perspectives, which supports the overall scope of the investigation.

The student shows an effort to balance the discussion by recognizing that passive warm-ups can have some useful effects as well.

Some terminology is inaccurate or imprecise, which reduces confidence in the scientific detail of the explanation.

Several claims are stated too broadly or too absolutely and would be stronger if more carefully qualified by evidence.

The psychological and physiological ideas are not always applied with equal precision to short-distance swimmers specifically.
