Task: Answer Verification
Input (English): Question: Is exercise training bradycardia largely explained by reduced intrinsic heart rate?
Answer: We did not find evidence that an increase in parasympathetic tone or a decrease in responsiveness to beta-adrenergic activity accounts for the reduction in resting heart rate with exercise training. We suggest that a decline in heart rate with training is most likely due to decrease in the intrinsic heart rate.
Output (English): yes
