“…In our species, it would seem that physiological changes produced in the fetus by maternal exercise return to normal levels fairly swiftly in most when the activity stops, although this happens more slowly in mothers with impaired fetoplacental circulations [Artal et al, 1984;Clapp, 19851. There may be a transient but significant increase in uteroplacental vascular resistance [Morrow et al, 19891, but the measurements so far seem to show a capacity to compensate for non-excessive work in pregnancy, particularly during exercise.…”

Pregnant women in the western world are increasing their part in paid employment. This can be added to their work in the home which, with their leisure and athletic activities, might add up to a considerable load; the possible effects this exertion could have on the woman and her unborn child has been realized only in the last twenty years and many attempts have been made to quantify it. The patterns of work in the home, in employment, and at sporting activity are assessed. There are two distinct areas of possible influence on the fetus: the work with its physical effort might affect respiratory and metabolic acid-base balance and specific teratogens related to activity at work may be encountered and act at nodal points during fetal growth at specific times, causing congenital abnormalities of organs. Potential hazards under chemical, physical, and biological headings are considered, while both the psychological and physical effect of energy expenditure are discussed. Possible measures of outcome are assessed and three recently published studies from the U.S. and U.K. are examined to show the difficulties of making valid measurements about the effect of work on the pregnancy, as well as that of pregnancy on the work. It is probable that ordinary work done by a fit young woman has no serious effect on herself or a healthy fetus. Research will continue, for it may be that with an impaired afferent nutrition and oxygen supply to the fetus, certain specific increases in degrees of work could have an exaggerated effect.

ZusammenfassungKörperlich aktiv zu sein während der Schwangerschaft führt noch immer zu Verunsicherung und zu Fragen: Wie viel und welchen Sport soll eine Schwangere ausüben, welche Folgen entstehen für Mutter und Kind? Während der Schwangerschaft führen erhebliche physiologische Veränderun gen in der Hämodynamik, im Respirationstrakt, im muskuloskelettalen System, im Glukosestoff wechsel und im weiteren Endokrinium sowie in der Psyche zu tief greifenden Veränderungen, die sich mannigfaltig auf die Fitness und die sportliche Leistungsfähigkeit auswirken. Unter Berück sichtigung allgemeiner Trainingshinweise, Vorsichtsmaßnahmen und Kontraindikationen ist ein Training entsprechend dem Fitnessgrad der Mutter zum Erhalt physischer und psychischer Fit ness möglich und wünschenswert. Viele Sportarten (Joggen, Nordic Walking, Schwimmen, Rad fahren u. a.) können in einer Schwangerschaft ohne Risiko betrieben werden. Die Auflockerung des Bindegewebes und die konsekutiven Bandinstabilitäten müssen sorgfältig bezüglich der aero ben Belastbarkeit berücksichtigt werden. Die Verletzungsgefahren bestehen bei fortgeschrittener Schwangerschaft in einer direkten Traumatisierung des Feten. Durch regelmäßige körperliche Ak tivität wird ein gesünderer Lebensstil gepflegt, weiter wird schwangerschaftsbedingten Erkrankun gen und deren Folgen vorgebeugt. AbstractBeing physically active during pregnancy often leads to uncertainty and questions: how much and which kinds of sport are possible? Changes in fitness and physical performance in pregnant women arise due to many physiological changes in hemodynamics, the respiratory system, the musculo skeletal system, glucose metabolism, endocrinological feedback and also in the psyche. Consid ering general recommendations for training, careful measures and contraindications, moderate or even vigorous training is possible depending on the individual mother's fitness and desirable to maintain physical and emotional fitness. Many kinds of sport such as jogging, nordic walking, swimming and cycling can be carried on during pregnancy without risk and promote the health of both mother and child. However, the mother's increasing weight and the resultant instability of ligaments must be kept carefully in mind to create a moderate aerobic workload. The danger of injury is present in later pregnancy and may lead to fetal trauma. For the pregnant woman a seri ous injury also includes the risks involved in the diagnostics and therapy. Regular physical activity means paying regular attention to a healthy lifestyle. This prevents diabetes, obesity, hypertension, thromboembolic deseases and their consequences in the mother's life but also the child's wellbeing.
