  1. Effect of forward rapidly rotating shift work on circadian rotating shift work on circadian rhythms of arterial pressure, heart rate and oral temperature in air traffic controllers.

    Article - En anglais

    Twenty-four-hour records of arterial pressure (AP), heart rate (HR), oral temperature (OT) and physical and mental performance were obtained in air traffic controllers during morning (n=16), afternoon (n=17) and night (n=19) shifts.

    Data were analyzed by the cosinor method.

    The results obtained during the morning shift were as follows (mesor/amplitude/acrophase) :

    • systolic AP (mm Hg) - 113.6/10.0/16 : 03 h ;

    • diastolic AP - 71.1/8.2/15 : 19 h ;

    • mean AP - 85.6/8.8/15 : 41 h ;

    • HR (beats/min) - 77.5/8.9/16 : 00 h ;

    • OT (dg C) - 36.71/0.21/15 : 49 h ;

    • right-hand grip strength (kg) - 49.8/2.0/17 : 43 h ;

    • left-hand grip strength - 46.1/2.0/16.08 h ;

    • mental performance (calculations/min) - 14.9/1.1/16 : 39 h. During the night shift either no change of the circadian acrophases (HR, right-hand grip strength) or acrophase delays ranging from about 2 h (systolic AP, OT mental performance) up to 3 h (diastolic and mean AP, left-hand grip strength) were observed.

    Our data suggest that the shift system studied does not significantly alter the circadian rhythms, and does not induce a desynchronization, particularly as concerns arterial pressure and oral temperature.
