Abstract
HIIT - sprint training can help all runners? Can all runners do the same training for better pace? This study examined blood Concentrations of CK, Urea, Gama Glutamyl Trasferase, GLycemia and Lactato before and after jump test (Bosco et. al), included twenty amateur runners. Blood samples were collected from the fingertip for [La-] assessment before and 1min after jumps test using aportable analyser (Lactate Plus®, Waltham, MA 02454-9141, EUA) and Reflotron Plus® (Roche) for the measure the other parameters, before and after 10 minutes. Jump performance were evaluated using CEFISE® Optical plataform and during one minute using counter moviment jump (CMJ). The main results were acutely great heterogeneity for muscle damage (CK) before 30~472 after 64~476, power indicated by the [La-] (internal load) before 0.8~3.2 after 3.8~12.8, and power by the platform of jumps (external load) 968~1583 Watts. The elevated capacity to produce power by some runners and the inabili ty of others also possible to observe and high (La-) values after test confirms the transition from energy sources (aerobic to lactic anaerobic). The study suggest that biomarkers, especially the lactate (confirmed by the jumping platform) allow to identify the runners that have the greatest capacity to produce power and then optimize their performance with HIIT (sprints training), however the runners that do not have this characteristic need other strategies, example, continuous training. In this way the training can be totally individualized, optimized the chances of success of the program and with great safety related to the health of the runners.
