LACTATE: A BIOLOGICAL MARKER OF PHYSICAL ACTIVITY IN COLOMBIAN WEIGHTLIFTING ATHLETES

ABSTRACT Introduction Blood biomarkers are measurable metabolic products that allow objective monitoring of the training process, and their analysis provides an opportunity to improve athletic performance. Objective To evaluate blood lactate concentrations in a group Valle League weightlifting athletes as tool determine effects its direct relationship performance during competition. Methods This is observational cross-sectional study. Lactate levels 32 belonging Weightlifting were evaluated. samples taken from ear lobe quantify concentration, using Scout analyzer. Samples before after high intensity section consisting four maximum repetition (MR) sports gestures, which 5 series 15 repetitions performed for each gesture, with rest period 40 seconds between exercise. The software program SPSS, version 25, was used concentrations. Results An average concentration 22.46 mg/dL obtained at rest, 98.30 final Significant differences found initial Conclusion increases physical activity; it varies one individual another; can be biomarker activity field sports. Level evidence; II type study: Prognostic Studies Investigating Effect Patient Characteristic on disease outcome.
