Assessment of Force Through Lactate as a Measure to Quantify the Training Load in Populations With Risk Factors

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.
