Summary

"Human tolerance to prolonged positive (headward) accelerations of sub-blackout magnitude has been investigated in this study. The data indicate that man is able to withstand the forces of positive g for durations much longer than previously supposed. Exposures as long as an hour at 3.0 g appear well tolerated by most subjects. Except for moderate tachycardia no pathologic abnormalities were observed in the electrocardiographic tracings recorded continuously on all subjects. Explored were the durations of tolerance at g levels varying from 3.0 to 6.0 g. The effects of anti-g suits upon tolerance are also reported."--Abstract.
