Gender-specific determinants of the cardiorespiratory system and energy supply for working capacity in sport dance athletes.

Objective

Aim: To identify specific functional characteristics of male and female partners in the semi-finals and finals of the standard European program. PATIENTS AND

Methods

Materials and Methods: Twenty-one professional standard European dance couples were assessed during semifinal and final performances; VO₂, VCO₂, VE, and lactate were measured using MetaMax 3B and Biosen+. To compare independent samples, the Mann-Whitney U test was applied; data are presented as mean, median, SD, min-max, Q1-Q3, and IQR.

Results

Results: No significant differences were found between SF and F in VO₂max, VO₂max/kg, VE, EqO₂, VCO₂, VCO₂/kg, or EqCO₂. A significant difference was observed for lactate (p<0.05). These findings indicate stable functional support across competitive rounds, while higher lactate values in the final reflect greater glycolytic load, particularly in female partners.

Conclusion

Conclusions: In most dancers, in F SEP, there was found an increase in aerobic metabolism in partners and glycolytic capacity in female partners. The reactive properties of the cardiorespiratory system are reflected in the efficiency of oxygen consumption per unit of pulmonary ventilation (EqO2) and the stability of the respiratory compensation response to metabolic acidosis.
