Fitness classes for pregnant women did not improve posture during pregnancy. This study found no detectable effect of Canadian-guideline-based exercise programs on spinal curvatures in expectant mothers.

Area of Science:

Obstetrics and Gynecology
Physical Therapy
Sports Medicine

Background:

Pregnancy often leads to postural changes and back pain.
Exercise programs are expected to mitigate these issues by improving posture.
The specific impact of Canadian guideline-based fitness classes on pregnant women's posture requires investigation.

Purpose of the Study:

To evaluate the effect of fitness classes for pregnant women on posture.
To assess postural changes, specifically lumbar and thoracic spine curvatures.
To determine if exercise interventions influence posture during and after pregnancy.

Main Methods:

Sixty-five pregnant volunteers were divided into an exercise group (27) and a sedentary control group (38).
Posture was assessed every 4 weeks using lateral photographs to measure spinal curvatures.

Knee ligament laxity was monitored using a clinical arthrometer.

Main Results:

No significant effect of the exercise program on posture was detected during pregnancy.
Weight gain partially explained increases in lordosis, but the effect was not substantial.
The fitness classes, designed per Canadian guidelines, did not demonstrably alter spinal posture.

Conclusions:

Fitness classes for pregnant women, following Canadian guidelines, showed no detectable effect on posture.
Current exercise regimens may not be sufficient to alter postural adaptations during pregnancy.
Further research is needed to explore effective interventions for managing posture in pregnant individuals.
