SUMMARY:

Introduction: The relationship between the Cardiorespiratory Optimal Point with body composition measures and biochemical variables is unknown, as well as the influence of genetic and environmental factors on this variable. In addition, research that uses discordant twins for physical exercise and evaluates their effects on metabolic risk factors is rare. Aim: To evaluate cardiorespiratory fitness, body composition and biochemical parameters in concordant and discordant twins for physical exercise. Methods: Cross-sectional study with adult twins. The sample consisted of 102 twins, 72.5% females and 27.5% males, with a mean age of 25.4 ± 5.69. Data collection was carried out between the years 2016 and 2018. On day 1, an assessment of the fitness of the whole body was not found, including anthropometric measures, body composition by Dual-Energy X-ray Absorptiometry, and Cardiorespiratory Exercise Test. On day 2, a 10 ml blood sample was collected (overnight fasting) to determine the lipid profile and fasting blood glucose. Spearman's correlation was used to verify heritability and to relate the variables to the Cardiorespiratory Optimal Point. The monozygote twins were separated into three groups: active concordant twins, inactive concordant twins and discordant pairs for physical exercise. The ANOVA test (p <0.001) was used for analysis between the groups and the Wilcoxon test (p <0.05) for an intrapar analysis. Results: There were no associations between Cardiorespiratory Optimal Point and body composition variables. The biochemical variables HDL, LDL, GLI and TG dissipated, but moderate. Differences were observed between pairs of discordant twins and groups for variables of body composition and metabolic profile including maximum oxygen consumption (VO2max), oxygen consumption corresponding to the first and second ventilatory threshold, lipid profile and fasting blood glucose. Conclusion: The Cardiorespiratory Optimal Point and the biochemical variables in general, showed a greater tendency to be influenced by environmental factors. Body composition, on the other hand, had a greater influence on heritability and compliance was not correlated with the cardiorespiratory optimum. In addition, the practice of physical exercises was sufficient to generate changes in body composition and VO2max in monozygotic twins, but not in the lipid profile or fasting glucose.
