PURPOSE: To determine the gestation effect on daily physical activities; and to evaluate the gestation effect on a 40-min-daily-walking-five-time-a-week intervention among sedentary pregnant women. METHODS: This is a randomized-placebo-controlled trial examining the effectiveness and safety of exercise on pregnancy, funded by NINR. Protocols were approved by the IRB. 70 women were recruited from nine clinics in the Midwest. Recruited women at 18 weeks gestation (wg), cardiovascular fitness being average or less, and free from disease, were randomly assigned to: 1) 40-minute-walking at the Rating of Perceived Exertion 12-13, five times weekly (n=37); or 2) a control group (n=33). Heart-rate monitors (Polar S810) recorded each walking exercise. Pedometers (DigiWalker SW200) recorded daily steps for both groups. RESULTS: Subjects, average age 31.7 (SD=4.4) years, were mainly Caucasians (82.9%). From 18 to 38 wg, the controls walked an average of 5571 steps daily. With each advance in gw there was an average reduction of 69 steps daily (95% CI: -111, -27). Daily steps were correlated with gestation with both groups (r=-.87, p<0.001 for exercisers; r=-0.80, p<.001 for controls). Exercisers 'walked' an average 3.5 times weekly for average 42 min. For daily physical activities, exercisers took an average of 2006 more steps daily (95% CI: 1370, 2641) than controls. For walking intervention, one further gw resulted in an average decline of 2.3 minutes (95%CI: -3.8, -0.7) duration and 0.4 beats/minutes (95% CI: -0.7, -0.2) in heart-rate. CONCLUSION: Women naturally reduce physical activities by approximately 300 steps per month during pregnancy. Women gradually reduce the exercise length by approximately 10 minuets weekly per month, tapering off naturally to term with decline of the intensity by 8 bpm over 20 weeks.
