Physical activity, sports and health during pregnancy.Which recommendations are currently existing?A certain precariousness amongst pregnant women concerning physical activity during pregnancy is very common. In this thesis the effects of physical activity on the health of mother and child, current recommendations for exercise for pregnant women and potential risk factors were researched. Beside numerous scientific studies, which were used as primary source of information, interviews with experts with practical experience were conducted. Physical activity can reduce the risk of pregnancy-associated diseases such as preeclampsia, gestational diabetes or depression and has a beneficial influence on labour and delivery. Pregnant women should accumulate at least 150 minutes of moderate-intensity physical activity per week and this should primarily contribute to maintain a healthy fitness level and increase the personal wellbeing. Recommended activities are Nordic Walking, cycling, swimming, aerobics or Yoga. The conscious breathing, which is practiced in Yoga lessons, is very useful in preparation for delivery. Also moderate strength training, especially of large muscle groups is recommended. During exercise it is of the highest importance to pay attention to the own body, to possible symptoms of discomfort and to avoid exhaustion. As pregnancy progresses adaptions of the physical activity should be conducted to meet the altered physical capacity. Sports such as skiing, contact sports or horseback riding have an increased risk of injuries and should therefore be avoided during pregnancy. Vaginal bleeding, dizziness, preterm labour or amniotic fluid leakage are alarming symptoms, which indicate an immediate termination of exercise. Further investigations are needed to determine the effects of high-intensity physical activity on maternal and fetal health. In terms of public health the awareness of the importance of physical exercise during pregnancy should be increased.
