Study: Sudden Cardiac Death in Bodybuilders Disproportionately High, Professionals Most at Risk
Study finds sudden cardiac death in male bodybuilders is unusually common, with professionals at highest risk; researchers urge screening and anti-doping.
A new analysis of competitive male bodybuilders shows that sudden cardiac death in bodybuilders is unusually common, particularly among professionals who face a markedly higher risk than amateurs. The study tracked more than 20,000 named competitors and found a substantial share of deaths were sudden and cardiac-related, raising concerns about practices and medical oversight in elite bodybuilding. Lead investigator Dr. Marco Vecchiato of the University of Padova and colleagues call for enhanced screening, surveillance and cultural changes within the sport.
Key findings on mortality and sudden cardiac death
The researchers identified 20,286 male competitors who had entered at least one international event between 2005 and 2020 and then searched public records for reports of death. They documented 121 deaths in that group, with an average age at death of 45 years and sudden cardiac deaths accounting for 38 percent of cases.
Professional bodybuilders were found to have more than a fivefold increase in the incidence of sudden cardiac death compared with amateurs, a differential the authors say likely reflects more intensive and prolonged exposure to competing practices. Autopsy information was limited but, where available, commonly showed heart enlargement and signs of coronary disease.
How the research team identified and verified cases
To compile the dataset the investigators used official competition records and an unofficial online database to assemble competitor names, then searched media, social networks and forums in five languages for death reports. Reported deaths were cross-referenced across multiple sources and reviewed by two clinicians to assign probable causes where possible.
The approach relied on publicly available information rather than centralized death registries, a strategy the team argued was the most feasible way to study an international, low-frequency outcome in a dispersed population. The authors acknowledged the method’s limits while noting the patterns they observed were robust across the information sources they examined.
Cardiac pathology and substance findings
Where post-mortem data were available, common findings included cardiac hypertrophy and enlargement, and in some cases coronary artery disease. Toxicology reports and other publicly accessible documents implicated the use of anabolic substances in a subset of deaths.
Investigators stress these pathological signs point to both structural heart changes and potentially modifiable exposures as contributors to sudden cardiac death in bodybuilders. They emphasize that substance abuse and repeated physiological stressors can act together to increase arrhythmic and ischemic risks.
Competition practices linked to increased cardiovascular strain
The study highlights several competitive practices that may strain the cardiovascular system, including extreme strength training regimens, rapid weight-loss strategies, severe dietary restriction and deliberate dehydration before shows. Investigators say these practices, intensified at the professional level, could promote structural and electrical heart changes over time.
Lead author Dr. Vecchiato and colleagues reason that prolonged engagement in extreme regimens and higher competitive pressure to achieve more extreme physiques likely expose professional athletes to greater cumulative risk. They caution that appearance alone does not equate to cardiovascular health and that some sport-specific behaviors carry hidden dangers.
Calls for medical screening, policy changes and anti-doping measures
The research team recommends proactive cardiovascular screening and counselling for bodybuilders, even among young and apparently healthy competitors, to detect risk factors early. They also urge federations and policymakers to develop targeted health surveillance programs and stronger anti-doping enforcement to reduce the prevalence of performance-enhancing substance use.
Medical associations and sports organizations were urged to collaborate on educational campaigns aimed at coaches, athletes and the wider gym-going public so that safer training practices are promoted. The investigators suggest that tailored clinical pathways may be necessary for athletes engaged in prolonged high-intensity bodybuilding to manage cardiovascular risk effectively.
Mental health and non-cardiac causes of death
Beyond cardiac causes, roughly 15 percent of the recorded deaths were classified as sudden traumatic deaths, a category that included crashes, suicides, homicides and overdoses. The authors note that mental health challenges within bodybuilding culture, sometimes exacerbated by substance abuse, may contribute to impulsive or self-harming behavior.
The study therefore frames the problem as both medical and psychosocial, pointing to the need for mental health support and substance-misuse interventions alongside cardiovascular prevention. Addressing these intersecting risks may reduce a broader spectrum of premature mortality in the sport.
The investigators acknowledge limitations in their work, including reliance on public reports that may undercount deaths or misclassify causes, and the current focus on male competitors because men constitute the majority of the competitive field. They indicate ongoing plans to study female bodybuilders and to examine trends over time as competitive and training practices evolve.
Taken together, the findings present a clear call to action: while strength training remains beneficial for general health, the extreme practices and unchecked use of performance-enhancing substances observed at the highest levels of bodybuilding appear to elevate the risk of sudden cardiac death. Sports bodies, clinicians and athletes are urged to work together to reduce harm and safeguard competitor health.
