SUMMARY: Introduction: The traditional way of measuring strength is through 1Rm, which is not very effective dynamics in patients undergoing cardiac rehabilitation . Goals: The objective of this study was to assess strength through lactate and determine a specific load that allows the development of this parameter in an aerobic condition in patients undergoing cardiac rehabilitation. Materials and methods; Through intentional non-probabilistic sampling, 25 male participants. Age 48.80 ± 4.49. Weight 95.40 ± 5.54. Height, 1.74 ± 0.06. % Fat 37.58 ± 2.68 % Muscle mass 38.62 ± 1.52. Vo2/kg 38.00 ± 2.73. min. They did two tests. Results: The results of the Anova analysis did not show significant differences between the different groups in lactate F (4, 17.1) =0.524, p=0.720. Heart rate F (4, 16.4) =0.457, p=0.766. The post hoc analysis of the Tukey test did not show differences between the group variables. Average heart rate (HR) during constant load resistance exercise. 133.9/5.48 (ppm). p=0.000. Blood lactate concentrations during exercise Mean 2.52/0.28. (mmol/l). p=0.000. Constant load 30/00 (kg) The results indicate that these metabolic and cardiac variables remained partially stable in aerobic energy ranges. Within the measurement of series 1, 3, 5, 7, 9, 11, 13, and 15. Conclusions: The values obtained from the constant load test show that the metabolic and cardiorespiratory variables remain stable in a predominantly aerobic metabolism, this could suggest that measuring strength through lactate is effective for strength training in patients with IC.
El presente ensayo temático es una reflexión introspectiva desde la docencia y de la experiencia educativa sobre las tensiones y limitaciones que se han evidenciado en la violenta transición, sin estar preparado ni formados académicamente, para pasar de una modalidad presencial de enseñanza y a una modalidad a distancia virtualizada, evidenciándose las particularidades y limitaciones propias, y las enormes desigualdades en los procesos de digitalización de la enseñanza, reflejadas en las limitadas competencias digitales de sus principales protagonistas, convirtiéndose las clases virtuales en la manzana de la discordia, especialmente en las universidades en America Latina y en el Ecuador. Se plantean los problemas teóricos, metodológicos y prácticos que se evidencian en base al conocimiento conocido sobre los factores limitantes y los posibles efectos en los procesos de enseñanza, de aprendizajes y desarrollo de competencias, así como los resultados mismos de la aplicación de la modalidad de clases virtuales de emergencia en un contexto de pandemia o de sindemia.
