Significance of Physical Exercise in Pregnancy: Comparison of Short and Long Exercise Programs.

Abstract

Background: Several musculoskeletal changes occur in pregnancy, particularly in the abdominal region. The aim of this study was to search and compare the effects of long (LEP) and short exercise programs (SEP) in terms of the satisfaction of the needs of pregnant women.

Methods: This study consisted of 2 groups: LEP (n=16) and SEP (n=16). Muscle thickness measurements determined by ultrasound, the 6 minute walk test, Pregnancy Physical Activity Questionnaire, Visual Analogue Scale, Oswestry Disability Index, and Short Form-36 Quality of Life Questionnaire were the study variables. Evaluations were done at the 16th (baseline), 24th, and 32nd gestational weeks. The LEP consisted of 20 and the SEP consisted of 9 exercises, which were applied for 16 weeks until the 32nd gestational week.

Results: Emotional role limitation and pain scores of quality of life, 6 minute walk test, and occupational physical activity were found to be better in the LEP group at the 24th gestational week (p=0.043, p=0.049, p=0.049, p=0.026). At the 32nd gestational week, the 6 minute walk test and occupational physical activity were found to be higher in the LEP group (p=0.006, p=0.017). Additionally, rectus abdominis and bilateral diaphragm muscle thicknesses, "moderate intensity and sports physical activity" and "vitality and emotional well-being" were increased over time with the LEP (p+<+0.05 for all). On the other hand, unilateral diaphragm muscle thickness, sports physical activity level, and vitality were improved with the SEP (p+<+0.05 for all).

Conclusions: The SEP and LEP both have beneficial effects in pregnant women. However, the LEP increases physical activity level, functional capacity, and quality of life more than the SEP during the later stages of pregnancy.
