Background: At Philadelphia's Lankenau Hospital there's plenty of activity in the Climatic Chambers. Strolling on treadmills or racing nowhere on static bikes, guinea pigs have their temperatures, pulse body heat and water loss and a host of other data recorded by instruments strapped to parts of their bodies. It's all part of an experiment to determine the effect of variations in protein on human performance, with temperature and diet constant.
Computers turn the signals into intelligible information which is typed automatically on a log. Temperature in the experimental chamber is set at 44 degrees, 12 above freezing. Results of performance under controlled conditions will help determine the minimum diet of protein needed by spacemen or soldiers. Little is known, explained hospital director Kaare Rodahl, about the effects of specific nutrients, especially protein, on the performance capacity of man in a cold environment.
But the 'guinea pig' doesn't spend all his time walking on continuous belts - though even during his sleeping hours instruments maintain their check on his various reactions.
