Physical activity has been proposed to influence the fecundability (probability of a women conceiving within a given time period) through alterations in endocrine function, lipid profile, reduction of stress and anxiety. Physical activity needs to be optimal as excessive exercise may cause disruption of menstrual cycle and thereby increasing risk of amenorrhoea and reduced fertility.
As per a recent study done among overweight or obese women having history of one to two prior pregnancy losses, walking ? 10 min at a time was associated with improved probability of conceiving within a given time period. Walking included ‘walking at work, at home, walking to travel from place to place, and any other walking done solely for recreation, sport, exercise or leisure activities’.
It also concluded vigorous intensity physical activity of >4 h/wk was also associated with higher fecundability in women regardless of body mass index (BMI). Vigorous intensity physical activity means activities that take hard physical effort and makes individual to breathe much harder than normal.
