A two-way analysis of variance ANOVA with repeated measures was used to evaluate any significant changes in the HR, metabolic and respiratory parameters for the BH periods and whether there were any differences between SS and controls. Adriana chechik nude pics. We found that the end tidal partial pressure of oxygen decreased the longer the breath was held during underwater exercise and was lower in synchronized swimmers compared to controls when the order of BH began with the short BH periods.
