摘要: Forty-two ambulance personnel engaged in a 24-h shift system participated chronobiological field study to the effects of work on circadian rhythm characteristics. Autorhythmometry rhythms oral temperature, right and left grip strengths, heart rate plus subjective assessment drowsiness, fatigue, attention was performed every ∼ 4 h except during sleep for 7 days. Cosinor power spectral analyses were applied longitudinal data each individual. Changes period different from 24 observed personnel. The incidence periodicity temperature strength 28.6%, 35.7%, 47.6%, respectively. relatively lower than that workers discontinuous 8-h we reported previously. Working conditions allowing ambulanc...
