A 24-year-old marathon runner, described as being in perfect health, died hours after completing the New York City Marathon due to rhabdomyolysis, a condition that can arise from intense exercise.
Rachel Apa collapsed in Central Park with two miles remaining in the race. She was transported to Mount Sinai hospital, where she died later that evening. Her father, Steve Apa, confirmed the cause of death to The New York Times as rhabdomyolysis.
Rhabdomyolysis occurs when skeletal muscles break down rapidly, releasing proteins and electrolytes into the bloodstream. The body struggles to process these substances, which can lead to critical organ damage. The protein myoglobin, released during muscle breakdown, can overwhelm the kidneys, causing renal failure. Additionally, excess potassium in the blood can disrupt heart function, potentially leading to fatal arrhythmias and cardiac arrest.
While rhabdomyolysis can result from various muscle injuries, including burns and certain medications, exertional rhabdomyolysis is specifically linked to high-intensity exercise or prolonged, extreme workouts.
Endurance athletes, such as marathon runners, and participants in activities like CrossFit or intense spin classes are at a higher risk for developing exertional rhabdomyolysis. A 2021 study noted that the condition appears to predominantly affect young, healthy women, suggesting that the desire to keep pace with others in fitness classes might contribute to overexertion. Dehydration does not cause rhabdomyolysis but can exacerbate the condition and increase the risk of severe complications.
Symptoms of rhabdomyolysis can include muscle pain, weakness, and dark-colored urine, though not all individuals experience all three. Other potential signs include fever, nausea, vomiting, confusion, and loss of consciousness. Immediate medical attention is crucial for suspected cases.
Treatment typically involves intravenous fluids to prevent further kidney damage. In severe cases, dialysis may be required. While many individuals recover fully, lingering muscle weakness can persist for weeks, and doctors often advise a significant period of rest before resuming exercise.
