Key result
Running was associated with lower resting heart rate and higher parasympathetic modulation compared to cycling in professional male athletes (P<0.05).
Why the study?
Does sport modality affect resting bradycardia level and its mechanisms of control in professional athletes?
Cross-Sectional (n=24)
Does sport modality affect resting bradycardia level and its mechanisms of control in professional athletes?
p-value: p=<0.05
Resting bradycardia in runners is primarily driven by autonomic mechanisms, whereas in cyclists it relies on non-autonomic mechanisms associated with cardiac hypertrophy.
No takes yet. Share an insight, caveat, or question.
Sport modality may differentially shape bradycardia mechanisms in athletes; leaves open whether autonomic versus intrinsic differences alter clinical risk.
Azevedo et al. (2014) conducted a cross-sectional in Resting bradycardia in highly trained athletes (n=24). Running vs. Cycling was evaluated on Resting heart rate and autonomic control mechanisms (vagal effect, parasympathetic modulation, autonomic influence, intrinsic heart rate) (p=<0.05). Running was associated with lower resting heart rate and higher parasympathetic modulation compared to cycling in professional male athletes (P<0.05).
