Influence of Physical Fitness against for a Long Period Time in First and Second Stage of Labor in Primigravida at Medan City Indonesia

Introduction, Physical fitness of pregnant women who are exercise actively have a better vascularization than those who passively. Physical exercise is a major factor in improving physical fitness, flow capacity of the heart, and obtain a high oxygen during labor (Varney and others 2007, Hamilton 1995, Bobak and others 2005), therefore team authors were interested in researching about physical fitness effectiveness for a long period time in cervical opening time (stage 1) and time of birth to the fetus (stage 2) in primigravida (first pregnancy). Method, This type of research is a Quasi Experiment and Non-Equivalent Control Group, population total are 40 respondents ( trimester III) primigravida (first pregnancy) measuring the level of physical fitness (VO2 max), period of 1st stage, 2nd stage and total period time of labor. Data analysis using T test. Result from 20 respondents of experimental group and 20 groups non-experiment obtained homogeneous data regarding physical fitness and psychological condition. The average time period of cervical opening time (stage 1) in experimental group are 387, 75 minutes (Sd.43, 54), the average time period time of birth to the fetus (stage 2) are 27, 75 minutes (Sd.9, 66). Total time childbirth average 334, 50 minutes (Sd.44, 35), while in non-experimental group the period time of cervical opening time (stage 1) average 448, 75 minutes (Sd.41, 64), time of birth to the fetus (stage 2) 40, 00 minutes (Sd.8, 27) and the average of total Time childbirth was 478, 75 minutes (Sd.82, 64). T test in the experimental group and non-experimental group obtained homogeneous data because p value (0, 794) greater than (0, 005). Period time of birth to the fetus (stage 2) p value (0, 602) greater than (0, 005). The period total time childbirth not normal, analysist using Mann Whitney test obtained p value (0, 00) less than (0, 005). Concluded, That there is the influence of maternal physical fitness with period cervical opening time (stage 1) and time of birth to the fetus (stage 2) and suggested for all pregnant women improving physical fitness with physical exercise using a bicycle ergometer.
