Forty two (56.7%) out of 74 who had not done sport before, went for walking after the protocol reading, and nine continued not doing exercise. Among 74 participants who had not done exercise before the protocol reading, 16 (21%) were doing exercise three times a week and 11 (14%) changed their habit to daily exercise practice (P<0.001). Forty percent (195 women) were anxious about doing exercise during pregnancy before guideline study, while 116 reported that after the protocol reading, they had no anxiety about doing exercises during pregnancy (P<0.001).
