Marathon runners injuries

What injuries are marathon runners at risk for?

There have been reports of lower body injuries in marathon runners which range from 20 to 80% but no reports could be found looking at whole body injuries including organ damage.

How many marathon runners are there?

According to Running USA statistics, “in 2013 there were 1,100 marathons run across the country generating 541,000 finishers with a breakdown of 57% men (308,400, all-time high) and 43% women (232,600, a new high overall and percent) and 47% Masters – 40 and older (254,300, also a new high overall and percent).”

Marathon runners and kidney damage

A recent study from Yale University which was published in the American Journal of Kidney Diseases examined short-term kidney damage in marathon runners.

“The researchers found that 82% of the marathon runners that were studied showed Stage 1 Acute Kidney Injury (AKI) soon after the race. AKI is a condition in which the kidneys fail to filter waste from the blood.”

Runners were tested both before and after the marathon. Blood and urine tests were used to help define kidney function abnormalities.

“The results of our study should be validated in larger cohorts with longer follow-up of kidney function.”

“The researchers stated that potential causes of the marathon runner related kidney damage could be the sustained rise in core body temperature, dehydration, or decreased blood flow to the kidneys that occur during a marathon.”

“While the measured kidney injury resolved within two days post-marathon, the study still raises questions about the effects of repeated strenuous activity over time, especially in warm climates.”

A prior study showed that some marathon runners required dialysis after a marathon. It is unclear what caused the injury and there was some concern that all 4 runners had taken an anti-cramp electrolyte supplement.

Marathon runners and heart disease

An article from ABC News suggests that marathon runners can have sudden changes in their heart rate referred to s cardiac drift.

There have been cases of sudden death in marathon runners. An article in  Medical Science Sports Exercise suggests the need for medical supervision in people who have symptoms of a heart problem such as chest pain. “Marathon runners, especially those with a family history of heart disease and other coronary risk factors, should not consider themselves immune to either sudden death or to coronary heart disease and should seek medical advice immediately if they develop any symptoms suggestive of ischemic heart disease. Physicians should not assume that “physically fit” marathon runners cannot have serious, life-threatening cardiac disease.

Marathon runners and liver damage

An article in the  Journal of Kinesiology suggested that marathon runners exhibited liver damage. “The results of ultra-marathon runners revealed damage to the liver and skeletal muscles, as well as acute metabolic responses that occurred 24 hours after the run.

Marathon runners and muscle injury

Muscles may exhibit small tears that can be painful.

Runners World suggest shorter strides reduce the risk of stress fractures, “A shorter stride will usually lower the impact force, which should reduce injuries,” says biomechanist Alan Hreljac, Ph.D., a retired researcher from California State University-Sacramento.”

There may be difficulty regulating core body temperature.

  1. Thank you for this information. I was watching a news report last night about marathon runners and kidney damage. It surprised me that it would be an issue. You went into more detail thanks for the clarity.

  2. My brother in law does ironman. He does it to keep fit and avoid heart issues, etc. This is interesting info. Bottom line is this old body is a temporary vehicle. Can’t live forever

Please comment, I would love to hear what you think about this information.
