Core Viewpoint - The sudden death of Zhang Xuefeng due to cardiac arrest has reignited discussions about the risks of sudden death during running, emphasizing that running itself is not the primary cause, but rather underlying health issues combined with improper exercise practices are the main triggers [3][5][8]. Summary by Sections Running Sudden Death Probability - Running itself is not a major cause of sudden death; rather, improper exercise combined with undiagnosed health conditions is the core issue. Regular and scientific running significantly reduces the risk of sudden death [8]. - A study published in the 2025 JAMA journal covering 29.31 million marathon and half-marathon finishers found that the incidence of cardiac arrest during events is only 0.54-0.60 per 100,000 participants, with a death rate of approximately 0.20 per 100,000, or about 1 in 500,000 [8]. - In contrast, the annual rate of cardiac sudden death in the general population in China is about 40 per 100,000, nearly 70 times higher than that of marathon events [9]. Core Causes of Sudden Death - Over 80% of sudden deaths during exercise are due to undiagnosed cardiac issues. The primary causes vary by age group: for those under 35, conditions like hypertrophic cardiomyopathy and congenital coronary artery anomalies are common, while for those over 35, coronary artery disease is the main cause [12][13]. - Other rare but fatal causes include myocarditis from exercising while ill, severe heatstroke, and exercise-induced complications in individuals with high blood pressure [13]. Risk Factors for Running Sudden Death - Individuals with pre-existing conditions such as hypertension, diabetes, or a family history of sudden death are at higher risk and should undergo professional cardiac assessments before exercising [15]. - High-risk behaviors include sudden high-intensity running without a fitness base, increasing running volume too quickly, and exercising while fatigued or ill [16][17]. - Environmental factors also play a role, with men being six times more likely to experience cardiac arrest during marathons than women, and specific times and weather conditions increasing risk [17]. Preventive Measures - To mitigate the risk of sudden death while running, individuals should undergo health screenings, especially those over 40 or with risk factors, and should engage in gradual training [19]. - It is advised to control heart rate during exercise, perform warm-ups, and avoid running when feeling unwell [19]. - Being prepared for emergencies, such as knowing the location of AEDs and having a plan for CPR, is crucial [19].
