Summary of hemodynamics data. Averaged values of Heart rate (a), Cardiac output (b) and Stroke volume (c) at rest and with each stage of physical exercise averaged for 15 subjects. Rest, ST1 and ST2 represent data acquired at rest, with 35 W and 45 W exercise respectively. Statistical analysis was performed using a one-way ANOVA with repeated measures and Tukey’s test for multiple comparisons. †P < 0.05, vs. Rest; ‡P < 0.05, vs. ST1. The data in the bar graph represent the mean ± SD
