Objective: To determine the effects of physioprophylaxis (PP) on blood lactate (BL) concentrations after maximal incremental stress test, considering that this is the application of techniques in sports physiotherapy to reduce signs of muscle fatigue that can trigger injuries due to overload.
Materials and Methods: Quantitative study, experimental type, longitudinal section in 12 university players. The group is divided into one control group (CG) with recovery at rest without PP and another experimental group (EG) to which PP is applied at the end of the test. Blood lactate is recorded with Accutrend Plus at the beginning of the test, (1) five minutes after finishing the test (2) and after the PP (3) at two different moments for intra-subject analysis.
Results: The following data were obtained regarding blood lactate clearance, Moment 1: Without Plan (WoP) 4.86±1.4 and With Plan (WP) 8.85±1.25 (p<0.05), moment 2: (WoP) 5.6±1.76 and (WP) 7.8±1.3 (p<0.05) in mmol/L, and intra-subject: (WoP): 5.25±1.58; (WP): 8.35±1.33 (p<0.05).
Conclusions: The clearance of lactate in the blood at 30 minutes post stress test in the EG is bigger than the CG, because they recovered with the physioprophylactic plan.
Resumen: Este artículo presenta los resultados del componente didáctico en un proyecto que efectuó la caracterización bacteriana de las cepas seleccionadas para la germinación de la quinua ( Chenopodium quinoa W.). Al respecto se diseñó y desarrolló un módulo de aprendizaje en 6 sesiones, con 28 estudiantes de grado 5 de primaria de una institución oficial del departamento de Boyacá en Colombia, organizados en equipos de 4 estudiantes para facilitar la distribución del material. Se analizó las concepciones hacia los microrganismos antes y después de la experiencia. Se observó que los niños aprenden conceptos relacionados con la microbiología como medios de cultivos, diferencias entre bacterias y hongos, reproducción e importancia de las bacterias promotoras de crecimiento vegetal. Se resalta la importancia de abordar estos temas desde escenarios de la educación primaria, para comprender alternativas ecológicas sobre crecimiento vegetal.
