ABSTRACT
Physical exercise can bring benefits to the cardiovascular and gastrointestinal tract. However, little is known about the adequate exercise intensity and how exercise responses are affects by sexual differences. AIMS: To evaluate the effect of an acute treadmill exercise session at ~ 75% of HRmáx on hemodynamic parameters and the gastric compliance of men and women. METHODS: The study included 22 men and women aged 18 to 29 years, physically active. The exercise consisted of a treadmill session at 75% of HRmáx. We monitored blood pressure (BP) and heart rate (HR). During the drink test, volunteers were asked to ingest 15mL of chocolate in 1min intervals, marking their satiety on a graphical scale combining verbal descriptors. RESULTS: There was a significant increase of hemodynamic parameters for both sexes after the exercise session (p <0.05). Exercise was also able to increase total ingested volume, time of ingestion and calories ingested (p < 0.05). Concerning the drink test, no influence of the exercise session on satiety scores was observed in the groups studied (p > 0.05). CONCLUSIONS: Acute moderate exercise promoted significant increase in hemodynamic parameters and gastric compliance in subjects of both sexes. However, there was no effect on the satiety scores and the volume ingested at each score
