THE ACUTE EFFECT OF RAST TEST ON OXIDATIVE STRESS AND MUSCLE DAMAGE MARKERS IN YOUNG ATHLETES

Few studies about the effects investigated of high intensity and short duration exercises such as Rast Test, which may favor the adequate control of training sessions and, consequently, athletic performance. The objective of this study was to investigate the acute effect of Rast Test on oxidative stress and muscle damage in young athletes. Participating were 09 young athletes, aged between 15 and 18 years. Rest Test determined PAN-peak, mean PAN, minimum PAN (534.8 ± 138.9, 714.6 ± 102.2, 285.2 ± 285.2 Watts, respectively) and FI (7.0 ± 1.5 Watts / sec) of the runner athletes, resulting in an increase of the lipid peroxidation analized by TBARS (pre: 0.48 ± 0.1 nmolEq MDA.mL vs post: 0.66 ± 0.0 nmolEq MDA. mL), antioxidant activity of glutathione (p <0.05), and increased serum lactate dehydrogenase concentrations (pre: 326.0 mmol / ± 72.65U / L and powders: 758.72 ± 135.09 U / L) and creatine kinase (pre: 278.1 ± 78.64 U / L and powders: 983.62 ± 339.49 U / L) <0.05). It is concluded that Rast Test promotes oxidative stress and muscle damage in young athletes.
