Title: Pregnancy has an impact of oxygen body building exercise over gravidity and childbirth ABSTRACT Purpose: Observes pre-natal has the oxygen gymnastic exercises training to the pregnancy and the childbirth influence. Method: The choice is pregnant above 16 weeks not to have any pregnancy complications and the complication at the beginning of parturient woman divides into stochastically has the oxygen gymnastic exercises training experimental group and has not accepted the training instruction control group each 80 examples, through is pregnant the later period self-sensation to two group of pregnant women, situations and so on childbirth way, course of childbirth, soft birth canal damage carries on the comparison, the observation pre-natal has the oxygen gymnastic exercises training to the pregnancy and the childbirth influence, for further carries out the pre-natal health education, the popularization gestation period setting-up exercises provides the basis. Finally: Through is pregnant situation investigation discoveries and so on later period self-sensation to the experimental group and the control group pregnant women, childbirth way, course of childbirth, soft birth canal damage, experimental group backache, the lumbago population are obviously less than the control group, the natural childbirth rate obviously is higher than the control group (P<0.01), splits the palace production rate obviously to be lower than the control group (P<0.01), the total course of childbirth mean time is 6.06 h, obviously is lower than the control group 8.08 h, when the childbirth the perineum integrity is higher than the control group, has the remarkable difference (P<0.01).PerineumⅡThe lacerated wound, the perineum lateral section number and so on is lower than the control group, has the remarkable difference (P<0.01). Conclusion: Is pregnant the intermediate stage development to have the oxygen gymnastic exercises exercise, increased the muscle shrinkage force and the joint ligament activity, reduced the gestation period to respond not good, controlled its body weight to grow excessively.Reduced symptoms and so on gestation period leg acid, backache.Is helpful in the reduction course of childbirth, enhances the natural childbirth rate, reduces splits the palace production rate, reduces the soft birth canal damage.Has the oxygen gymnastic exercises through to propose the anus movement, the leg department movement, sits cross-legged sits, sways from side to side the pelvis, the vibration pelvis and so on, has exercised the thigh muscle, the pelvis bottom muscle, the lumbodorsal region muscle, the abdomen myo- muscle, thus strengthened the abdomen muscle, the lumbodorsal region muscle, the pelvis muscle strength and the elasticity, causes when the childbirth various spots related muscle can according to request all to mobilize, therefore can reduce the childbirth time, prevent the soft birth canal damage and postpartum hemorrhage. Key word: Has the oxygen gymnastic exercises Childbirth Birth pains paper type: Experimental research
