| Abstract: | Healthy males were tested for orthostatic tolerance during and following 21 days head-down bed rest. ECG and blood pressure were measured. Ten out of the 15 subjects were able to complete the head-up tilt (HUT) test following bed rest, and changes in heart rate dynamics and blood pressure were observed in both finishers and non-finishers. Specific results are presented and discussed. |
