Chapter 12: Problem 4

Pregnant women often assume a posture with their shoulders held far back from their normal position. Why?

Short Answer

Expert verified
Pregnant women often hold their shoulders far back from their normal position as a physiological adaptation to maintain balance. The growing abdomen shifts the body's centre of gravity forward, causing strain. To counterbalance, the body pushes the shoulders back and arches the lower back, helping to maintain balance and stability.

Step by step solution

01

Understanding the changes during pregnancy

During pregnancy, a woman's body undergoes many changes to accommodate the growing fetus. One major change is the alteration in the woman's body shape as her abdomen expands.
02

Discussing the effects on centre of gravity

As the abdomen grows, it shifts the woman's centre of gravity forward. This can cause a strain in maintaining balance and posture.
03

Body’s response and changes in posture

To counterbalance the shift in the centre of gravity, the body adjusts its posture. The posture adopted often involves pushing the shoulders back and arching the lower back.
04

Reason for the particular posture

This posture helps to maintain balance and stability, thus minimizing the risk of falls and other injuries during pregnancy.
