Which statement best explains why the supine recovery position is recommended after exercise?

• A. It increases heart rate and blood pressure
• B. It increases venous pooling
• C. It decreases venous return
• D. It enhances ECG detection and reduces cardiovascular strain

Answer: (D)

Position after exercise affects both how hard the heart has to work and how clearly we can monitor it. In the supine recovery position, gravity pulls blood less from the legs, so venous return to the heart is improved and the heart doesn’t have to work as hard. At the same time, monitoring the heart’s rhythm is easier because the chest leads are more stable and there’s less movement, reducing signal noise. That combination—better ECG detection and reduced cardiovascular strain—is why this position is recommended. The other ideas don’t fit as well: lying down doesn’t elevate heart rate or blood pressure; it actually helps keep them steadier. It also doesn’t increase venous pooling; it reduces pooling compared with standing. And it doesn’t decrease venous return; it enhances it.
