Abstract
The purpose of this study was to investigate the relationship of body composition and biochemical variables with the cardiorespiratory optimal point, as well as to observe the tendency of heritability. This is a descriptive study with a cross-sectional design with adult monozygotic and dizygotic twins. To obtain the COP values, the cardiopulmonary exercise test was performed using a treadmill ramp protocol. For body composition, dual energy absorptiometry and anthropometry were used. For inferences, the Spearman correlation and the Mann-Whitney hypothesis test were performed. The results showed that the body composition variables did not significantly correlate with the cardiorespiratory optimal point. The Cardiorespiratory Optimal Point and biochemical variablesdemonstrated a greater tendency to be influenced by environmental factors and the body composition variables showed a greater influence of heritability.
