Níveis de lactato em praticantes e não praticantes de exercícios físicos antes e após exercícios de alta intensidade. Revista Científica JOPEF, Vol.28, n.1, pp.62-74, 2019. Lactate is a source of energy produced naturally by the body, when the need for energy is greater than that available, as in long-term exercises, for example. The glucose available in the cells is broken through a process called Glycolysis, which produces pyruvate, which, when it is not exposed to oxygen, becomes lactate. Lactate is often confused as causing muscle fatigue, but its only function is due to the production of energy. The objective of the study was to compare blood lactate levels before and after high intensity physical activities, with as research subjects individuals who practice and do not practice physical activities in their daily lives. For the accomplishment of this study, a bibliographical research was developed in the databases of Google Scholar from the following keywords: Lactate, muscle, muscle fatigue and lactate levels. And the practical research is due to blood collection before and after high-intensity exercises of practitioners and non-practitioners, as well as a questionnaire about diet and daily physical activity practices. It is possible to conclude that lactate production levels differ according to metabolism. However, after physical exercise, what changes is the fact of rapid elimination, since those who have an exercise routine obtained a faster elimination of lactate in the lactate. Blood than those who do not practice activities. Keywords: Lactate; Muscle; Muscular Fatigue
