The effect of age on the G tolerance of rats was studied in five different age groups - one, three, four, six, nine and twelve months. Each group consisted of 24 male Sprague-Dawley rats. All of the rats were subjected to 20 positive G and their survival times were measured using an EKG end point. The results show that there was a gradual decline in acceleration tolerance with increase of age in this group of 98 rats.
