常见错误

1. 1high涉及分数: 3Injury (Biomechanics)

   Attributing Delayed Onset Muscle Soreness (DOMS) to the accumulation of lactic acid.

   如何避免: Explain that DOMS is caused by microdamage/micro-tears in eccentric muscle fibers, which triggers an inflammatory response. Clarify that lactic acid is cleared from the blood shortly after exercise and is not the cause.
2. 2high涉及分数: 2Study Design and Research Methods

   Treating standard deviation (SD) error bars as direct proof of accuracy or error, rather than data variability.

   如何避免: Define standard deviation as the dispersion of data points around the mean. When comparing means, state clearly that overlapping error bars indicate that the observed differences are not statistically significant.
3. 3medium涉及分数: 1Study Design and Research Methods

   Failing to write down intermediate math steps, leading to zero credit when final values are calculated incorrectly.

   如何避免: Always show your full working (e.g. subtraction steps or fraction setup for percentage changes) so that method marks can be awarded even if a rounding error occurs.
4. 4medium涉及分数: 2Generating movement in the body (Biomechanics)

   Conflating the functions of ligaments and tendons during joint movement explanations.

   如何避免: Consistently define ligaments as connecting bone to bone (to stabilize joints) and tendons as connecting muscle to bone (to transmit force and generate movement).
5. 5high涉及分数: 2Generating movement in the body (Biomechanics)

   Using colloquial or abbreviated muscle names like 'pecs', 'delts', or 'hamstrings'.

   如何避免: Use the full anatomical terms: pectoralis major, deltoid, rectus femoris, and biceps femoris.
6. 6medium涉及分数: 1Response (Exercise physiology and nutrition of the human body)

   Omitting the word 'maximal' when describing training-induced changes in stroke volume or cardiac output.

   如何避免: Ensure you specify that while submaximal heart rate may decrease with training, stroke volume increases at rest and cardiac output increases during maximal exercise.
7. 7medium涉及分数: 2Forces, motion and movement (Biomechanics)

   Drawing force arrows that do not originate from the correct point of contact or center of mass.

   如何避免: Begin the tail of your force vector arrow exactly at the application point (e.g., foot-to-ground contact or the system's center of gravity) and include a clear directional arrowhead.
