A TECHNIQUE FOR PRODUCING CALISTHENIC BEHAVIOR IN A RHESUS MONKEY

摘要

A technique for exercise to counteract the effect of zero gravity on skeletal muscles in unrestrained monkeys during extended orbital spaceflight was explored. A rhesus monkey was reinforced with both food and food-associated stimuli for making a high-effort response continuously for 3 to 4 hours. Various manipulations of the frequency of food reinforcement and signals indicating the availability of food were used to evaluate the effect of each on the exercise response and associated behavior.
