The mean (± SEM) cardiac output (CO), heart rate (HR), and stroke volume (SV) in twelve healthy women (•) and eleven healthy men (▲), after the ingestion of a meal consisting of rice pudding. The letter a indicates a significant difference in response in the postprandial phase compared to fasting, calculated using the Wilcoxon t-test (P < 0.05). The letter b indicates statistically a significant difference compared with the value at 30 min, according to the Wilcoxon U test (p < 0.05). *A significant difference was also found between the men and the women, according to the Mann-Whitney U test (P < 0.05).
