Chilean Bodybuilder Marianne Gierke Dies Weeks After Competing in Mr. Olympia
The 40-year-old athlete's cause of death was not immediately specified, but premature deaths in bodybuilding are often linked to extreme training and preparation methods.
Marianne Gierke, a 40-year-old bodybuilder from Chile, died two weeks after participating in the female division of the Mr. Olympia competition in Las Vegas. The National Physique Committee of Chile announced Gierke's death on Wednesday, remembering her for her dedication, discipline, and her presence on the Mr. Olympia stage.
Her cause of death has not been disclosed. In the months leading up to her passing, Gierke experienced a successful competitive season. In August, she secured first place in the Women's Physique Division at the 2026 Rising Phoenix Women's bodybuilding competition in Phoenix, Arizona. She also placed 13th in the Women's Physique category at Mr. Olympia.
Gierke is survived by her 11-year-old son, Luciano, and her partner, Juan Cofre Garcia. Luciano had accompanied his mother to Las Vegas for the competition.
The Women’s Physique category is described as a division for female bodybuilders who possess more muscle than figure athletes but less than those in women’s bodybuilding.
Premature deaths have occurred with some regularity within the bodybuilding community, frequently attributed to the extreme physical conditioning required for competition. Last year, Spanish bodybuilder Lorena Blanco, 37, passed away following a heart attack while preparing for the Bikini Division at Olympia. Other recent notable deaths in bodybuilding from cardiac complications include Einar Mendez and Juan Sebastian Anzola Quintero.
According to the European Society of Cardiology (ESC), sudden cardiac arrest is a disproportionately common cause of death among both female and male bodybuilders worldwide. A study led by Dr. Marco Vecchiato, a sports and exercise medicine physician, indicated that extreme training, fasting, dehydration strategies, and the use of performance-enhancing substances can significantly impact the heart and blood vessels.
This study was initiated to address a lack of data concerning female bodybuilding athletes. It found that sudden cardiac arrest was the most frequent cause of death, accounting for 31 percent of the 9,447 cases examined, with the average age at death being approximately 42 years. The study also noted that suicide or homicide accounted for 13 percent of deaths, a figure Dr. Vecchiato linked to the particular psychosocial pressures experienced by female bodybuilders.
