Why healthy marathoners can collapse from muscle breakdown
Rachel Apa, 24, died from rhabdomyolysis, a sudden muscle breakdown that can strike fit endurance athletes even after successful training.
Rachel Apa was 24, healthy, and fit when she collapsed just two miles from the finish line at the New York City Marathon. Hours later, she died from rhabdomyolysis.
Rhabdomyolysis is when muscles break down fast, flooding the blood with proteins and salts that harm the kidneys and heart. Young, healthy women who train for long runs face higher risk.
Peer pressure often pushes them past safe limits. Watch for muscle pain, weakness, and dark urine.
Many people get only one or two warning signs. The condition strikes about 26,000 Americans yearly.
Athletes in marathons, spin classes, and CrossFit face greater risk. IV fluids can stop severe kidney damage when given early.
Most people recover, but muscle weakness often stays for weeks.
