Banana isotonic drink improves orthostatic tolerance in voluntary dehydration subject

This study was conducted to determine the effects of the banana isotonic drink that has been developed on orthostatic tolerance. Experimental research used cross-over design involved 16 subjects who passed the screening for voluntary dehydration and were divided into two groups. Each subject was administrated with 500 ml of fluid and subjected to schellong test for heart rate and blood pressure monitoring. Banana isotonic group had the higher cardiac activity than in plain water group to maintain blood circulation to meet the body volume and it showed a rapid tolerance to blood pressure when the subject provoked to upright position compared to plain water. Banana isotonic drink showed more improvement for the orthostatic tolerance in voluntary dehydration subject.
