A resting heart rate greater than 120 bpm indicates what for exercise?

A resting heart rate greater than 120 bpm indicates what for exercise?

• A. It indicates no issue; you can continue normal training.
• B. It may indicate hemodynamic instability; exercise intensity should be limited.
• C. It indicates improved cardiovascular efficiency with training.
• D. It requires maximum effort immediately.

Answer: (B)

A resting heart rate that high is a red flag. It means the heart is already working unusually hard just at rest, which can signal tachycardia from various stresses such as dehydration, fever, infection, anemia, or a heart rhythm problem, all of which can reflect instability in how blood is circulating. In the context of exercise, starting from a resting rate over 120 beats per minute suggests the body may not handle added work safely. Pushing into activity could worsen perfusion, increase risk of dizziness or fainting, and raise the chance of cardiac distress. The appropriate response is to limit exercise intensity and pursue evaluation to identify and address the underlying cause. This is not a sign of normal training adaptation (training tends to lower resting heart rate over time) and it’s not a cue to ignore symptoms or push to maximum effort. It’s a warning sign that warrants caution and medical assessment.
