BEACON TRANSCRIPT – Many people think that running a marathon is beneficial for your health. However, researchers from Yale University questioned this assumption in a new study and discovered that people who participate to marathons show some have their kidneys injured after a long race.
For the study, published in the American Journal of Kidney Diseases, researchers wanted to analyze how long runs impact kidney health. Thus, they gathered data from several runners who participated to the 2015 Hartford Marathon. The runners were analyzed both before starting the marathon and after finishing the run.
The runners’ kidneys acted as if injured
They sook markers for several kidney injuries, so they collected samples of blood and urine. Then, they looked at the creatinine and other protein levels, and kidney cells in microscopy. The results were not pleasant at all. Around 82 percent showed signs of severe kidney injury immediately after they had finished the race. Therefore, their kidneys could not cope with filtering all the waste in their blood during the run.
Dr. Chirag Parikh, the lead researcher and a medicine professor at Yale University, declared that the kidneys of the runners reacted as if they had been injured during the race. The behavior was similar to that seen in patients who suffer several complications which end up affecting their kidneys. Fortunately, the kidneys of the runners returned to normal several days after the run.
The study faces skepticism
However, there are some people who are skeptical. Dr. Adam Ramin, from the Urology Cancer Specialists, Los Angeles, argues that these tests are not as accurate as you might think. For instance, some of the markers might indicate both kidney damage or muscle damage. Also, if people are healthy, they can recover after this short-term damage they suffer after the race.
The suggests one important thing, namely that only healthy people should run in a marathon. Those with certain health problems might not be able to recover after a long run.
“This shows that you should be in good health to run a marathon. If you train properly, then a little damage to the kidney during the race isn’t harmful or permanent.”
If you choose to be part of a marathon, do not forget to drink a lot of of water during the run. One of the biggest risks during such races is dehydration. You may shorten the injury risks significantly if you hydrate properly.
