Common student misconceptions in exercise physiology and biochemistry
Type: Empirical
Data collection method: Test
Number of subjects, range: Small — 10 or fewer
Grade and age of subjects: Adult — over 18 years
- Lactate is only produced when muscle contracts under anaerobic conditions.
- Lactate causes fatigue.
- Fat is only used as an energy source during exercise when carbohydrate sources run out.
- To maximize fat loss during exercise, exercise intensity should be high.
- The process of muscle contraction consists solely of peripheral processes.
- When a muscle shortens in length during contraction, the A-band also shortens.
- VO2 max (maximal oxygen uptake) is the most important determinant of endurance performance.
- Oxidation reactions only involve oxygen molecules.
- Blood pressure is higher during prolonged exercise in hot conditions compared with normal conditions.
- Brain blood flow increases during exercise.
