The responses of the diurnal cycle of pulse rate to transatlantic flights with a 6 hr time shift were studied in eight untrained students during submaximal exercise. For this purpose the subjects were tested on a bicycle ergometer in 3 hourly intervals on two separate days before the outgoing and on days 1, 3, 5 and 8 following the outgoing and the homegoing flight. The sojourn in the U.S. was 16 days. Results showed a significant desynchronization of the diurnal cycle of pulse rate after the transmeridian flights with an average readaptation time of five days. No distinct differences were observed with respect to the direction of flight. (Author)
