Abstract: | Summary Further analysis of temperature rhythms obtained in an earlier study of 38 subjects subjected to an 8-h eastward transmeridian flight showed that the extent to which the phase of the rhythm was shifted after the flight was related to the phase angle of the pre-flight rhythm. Late peakers shifted more than early peakers , and this difference between the two types was still as large after 12 days in the new time zone as on the first day. Because the phase-shift was an advance one, this meant that the pre-flight individual differences in phase-angle were abolished by the flight, and had not re-appeared by the end of the observation period. It is suggested that this may have been due to an increase in the rigidity of the routine in the post-flight stage of the study, and that a similar effect may also occur in a switch from day to shiftwork. |
