Which of the following is a positive finding regarding heart rate in exercise testing?

• A. Failure to exceed 100 bpm
• B. Failure to fall below 60 bpm
• C. Failure to reach 120 bpm with max exercise
• D. Increase in heart rate during rest

Answer: (C)

In the context of exercise testing, a positive finding regarding heart rate is indicated by the ability to reach a target heart rate during max exercise. A response in which an individual fails to reach 120 beats per minute with maximal exertion suggests an inadequate cardiovascular response to exercise. This may be indicative of poor cardiac fitness, ineffective cardiovascular function, or potential underlying cardiovascular issues. An increase in heart rate is expected during exercise as the body responds to heightened demand for oxygen and blood flow to the muscles. Therefore, failing to exceed a certain heart rate during max exercise is a concerning finding, whereas achieving or exceeding expected heart rates signifies a more favorable cardiac response. This answer highlights the importance of proper heart rate responses during exercise, which are crucial for assessing cardiovascular health and fitness levels.
