Hemoglobin precautions: If Hb > 10 g/dL, what level of exercise is recommended?

• A. No exercise
• B. Light exercise
• C. Moderate exercise
• D. Resistive exercise

Answer: (D)

When hemoglobin is above 10 g/dL, the blood’s ability to deliver oxygen to working muscles is adequate to support more demanding activities. This level makes resistance training a safe and effective way to preserve and build muscle strength, which is crucial for functional independence and reducing fatigue. The metabolic demands of lifting or using resistance equipment can be met without excessive cardiovascular strain, so introducing or continuing progressive resistance exercises is appropriate. Start with light resistance and progress gradually while monitoring for fatigue, dizziness, or shortness of breath to keep it safe. Restricting to no exercise would miss these strength benefits, and while light or moderate aerobic activity is also safe, the exercise type best aligned with improving functional strength at this Hb level is resistive exercise.
