Abstract : Changes in patellar reflex time under various conditions were studied on 69 subjects. Reliability of reflex time mea ured on the same day two-three hours apart and also on different days was found to be high, being 0.94 and 0.90 respectively. Both legs of 15 subjects were heated in a ''Baker'' at a temperature of 130 F for 30-40 minutes. The refxhaustion the reflex time became longer. Neuromuscular excitability of the peroneus brevis muscle and the superficial peroneal nerve was measured after an exhaustive ergocycle ride for nine subjects. The excitability of both the heat prolong reflex time. Mild exercise tends to shorten reflex time. No relation was found etween reflex time and nex time increased by 7.8 sec. (9.6%), the difference being significant at the 0.1 level. After an ergocycle ride t exhaustion the reflex time became longer. Neuromuscular excitability of the peroneus brevis muscle and the superficial peroneal nerve was measured after an exhaustive ergocycle ride for nine subjects. The excitability of both the heat prolong reflex time. Mild exercise tends to shorten reflex time. No relation was found etween reflex time and neuromuscular excitability. (Author
