We recommend you check your own blood pressure prior to booking a test, as we cannot test anyone with a blood pressure of 160/90 mmHg or above. It is recommended that you do not take part in heavy exercise 72 hours prior to the date of your test.
With regards to food consumption, a pre-exercise high-carbohydrate beverage/meal elevates CHO-burning, suppresses fat oxidation, and will directly impact testing. Therefore, testing in a fasted state will reflect an individual's ‘raw’ state. However, it is unlikely that an athlete would begin an event without having consumed anything. Therefore, the individual could consume the same food that they typically consume before a race.
