Abstract Clinical data from 34 deliveries in the sitting position were compared with 59 supine deliveries. There were no significant differences between the two groups either in the duration of labor or in fetal well‐being as measured by data from the FHR pattern, umbilical blood gas analysis and APGAR score. However, analysis of the uterine contraction wave revealed a significant elevation of the resting tonus and shortening of the duration of the uterine contraction in the sitting group. These suggest that the reduced duration of the uterine contraction gave equivalent or better delivery force. Mothers declared they were more comfortable and could more easily make bearing‐down efforts in the sitting position than in the supine position. It is concluded that labor in the sitting position is not only a physiological but also a favorable posture for the management of labor.
