The changes in lactate levels and body weight during a regional and single Triathlon competition in Sergipe, Brazil
Year: 2014
Type: article
Abstract: The main tissue that produces and releases lactate during exercise is the skeletal muscle. Triathlon competitions can result in dehydration and lactate variation. The aim of this study was to evaluate the changes in lactate levels and the body weight during a single Triathlon competition in Sergipe, Brazil. Fifteen regional male triathletes age 31,33 ± 9,22 years and body weight 72,9 ± 8,8 Kg voluntarily participated of this study. Blood samples were collected 30 minutes before the beginning of the competition, and between 7 and 9 minutes after the last stage of the Triathlon competition. Shapiro-Wilk test, Student's t test two-tailed, and the absolute delta were used to do the statistical analysis. It was adopted p<0.05. When compared the pre and post lactate levels (Pre 4.91 ± 1.0 vs Post 6.95 ± 2.7 mmol.L-¹; p<0.01) and the body weight (Pre 72.9 ± 8.8 vs Post 71.4 ± 9.1 Kg; p<0.0001) of the participants was found a significant difference. A single Triathlon competition increased the blood lactate concentrations and promoted reduction of the body weight from regional male triathletes.
