Question

Which of the following is true concerning the physiological effects of immobility?

a) Intestinal mobility decrease

b) Hypertension and increased cardiac workload occur

c) Basal metabolic rate increase

Answer 1

Immobility or prolonged rest causes:

Intestinal mobility decreases leading to constipation and anorexia. Decreased bowel motility

Blood pressure tends to decrease. This happens because there is peripheral pooling of blood. Pooling occurs due to decreased muscle contraction which causes pooling of blood resulting in less blood reaching heart which in turn causes low blood pressure.

Resting or basal metabolic rate decreases with immobility . This happens because of muscle inactivity and loss of muscle mass due to disuse atrophy.

True statement: intestinal mobility decreases
