12.5% of athletes exhibited >1 premature ventricular beat per hour, and arrhythmias were significantly associated with years of training and caffeine intake during the race (p<0.05).

Overview

May inform arrhythmia monitoring considerations in master athletes; leaves open prognostic implications and causality of associated factors.

Key Points

  • This study investigates the prevalence and factors linked to arrhythmias in male master athletes during a marathon.
  • Enrolled 104 male athletes over 30 years old with specific performance and health criteria.
  • Fitted athletes with ECG monitors for real-time heart rhythm analysis during the marathon.
  • Analyzed the frequency of arrhythmias, including premature ventricular beats and ventricular tachycardia.
  • 12.5% of athletes displayed more than one premature ventricular beat per hour.
  • 5.8% had recurrent premature ventricular beats, while 3.8% experienced non-sustained ventricular tachycardia.
  • Significant associations found between arrhythmias, training years, and caffeine intake (p<0.05).

Structured PICO

P
Population
104 male athletes (>30 years) competing in a Marathon. Inclusion criteria: completion time <4 h 15 min, no known cardiovascular disease, and no beta-blocker or antihypertensive therapy.
I
Intervention
Marathon running with continuous lightweight ECG monitoring
O
Outcome
Prevalence and determinants of arrhythmias during endurance exercisesurrogate

Ventricular ectopy during a marathon in male master athletes is infrequent, largely benign, and associated with less training and caffeine intake.
