Analysis Of The Kinetics Of Lactate Removal In Slalom Kayak Athletes [análise Da Cinética De Remoção De Lactato Em Atletas De Canoagem Slalom]

The aim of this study was to verify the kinetics of lactate production and removal in slalom kayak athletes, K1 category, during official competition. Eight male athletes (22,6 ± 4,3 years) participated of the study. For the analysis of lactate, 25μL of capillary blood were collected. The kinetics of lactate removal was performed before the warm-up (Pre), just after the competitors exit from the river (Post 0'), 5 (Post 5'), and 20 (Post 20') minutes. The results demonstrated a significant increase in lactate concentrations (9.8 mmol/l, 9.4 mmol/l and 6.6 mmol/l) at 0', 5' and 20' post respectively, with values of P<0.01. The findings indicate that after 20 minutes the values of lactate reduced significantly (P
