Lactate in capillary blood after a vertical jump
This study seeks to determine if variations of carbohydrate intake, before the execution of a short stimulus, may have an impact on lactate concentrations in the athlete's body. Conducting a test with a short stimulus (Abalakov’s jump), 12 athletes were evaluated (elite category), in 4 days of interleaved testing: on the first day they were provided with a special diet (low in carbohydrates), the second day they were asked to perform the test, on the third day they changed the diet (high in carbohydrates), and on the fourth day the test was again performed to compare both moments. For the tests, capillary blood should be extracted from the ear lobe, being the athlete at rest, the subject performs a vertical jump without impulse and followed by this, samples are taken after 1, 3, 5 and 7 minutes. The procedure is the same for both tests, as a result it is observed that in both moments, the type of diet low or high in carbohydrates does not influence the concentration of lactate in the blood capillary of the athletes.
