Method Abstract, Materials and Methods (Please note, measurements between groups of men and women were switched by mistake): "Thirty healthy men (age 21.2±0.7 years, body mass 63±6.3 kg, height 168.3±5.1 cm) and thirty healthy women (age 21.3±1.9 years, mass 82.5±7.9 kg, height 181.9±4.9 cm) were included in this study. Echocardiography was used to assess cardiac and hemodynamic parameters. CPO [Cardiac power output] was calculated, at rest and after performed maximal bicycle test, as the product of cardiac output and mean arterial pressure, and CR [cardiac reserve] as the difference of CPO value measured at peak exercise and at rest."
Comments P.61 left column 2nd paragraph: "Women and men were almost the same age, but there were significant differences (p<0.05) in body height and body weight between these two groups (age 21.2 ± 0.7 years, body mass 63 ± 6.3 kg, height 168.3 ± 5.1 cm vs. age 21.3 ± 1.9 years, mass 82.5 ± 7.9 kg, height 181.9 ± 4.9 cm). Heart’s size and volumes of all subjects measured at rest were in physiological limits. There were significant difference between groups in all heart’s size and volumes parameters measured by echocardiography, except in IVSTs [end systolic intraventricular septal wall thickness] parameter (Table 1) The group of men had higher stroke volume (75.2 ± 11.9 ml versus 66.4 ± 11.6 ml, p<0.05) and cardiac output (5.9 ± 1.3 l versus 5.2 ± 1.3 l, p<0.05), but the two groups had similar values of cardiac power output (1.04 ± 0.3 W versus 1.14 ± 0.25 W, p>0.05)."
