Rhabdomyolysis: The Effects Of Overtraining


Junior Dos Santos had to learn the hard way about the effects of training too hard. Overtraining for a fight can be extremely critical to your health. Overtraining happens to many athletes that compete in combat sports. Scheduling your training sessions so that you peak at the right moment is crucial to combat sports.

Junior trained to the point that he peaked 15 days before his fight with Cain Velasquez took place by constantly pushing his body to its breaking point. Knowing that, he still had to continue training so he could defend his heavyweight title at UFC 155.

Unfortunately, the overtraining did him no favors once the fight started in the octagon. Cain Velasquez controlled the whole bout by pressuring Dos Santos with an unrelenting pace, great wrestling, and improved boxing. Dos Santos was no match for Velasquez.

The morning after the fight, he noticed that his urine was a dark brown color, like the color of guinness beer. It wasn’t blood that was coming out, but something entirely different. He consulted with experts at Nike and was told that he had rhabdomyolysis. His muscle fiber had broken down and ended up in his blood stream.

They also realized that his creatine kinase was way too high. The average level for an adult male is 300, Dos Santos’ level was around 1400 after his fight. He was pushing his body over the limit and was not getting enough rest to let his body heal.

Training is necessary in all sports, “Practice makes perfect is what we were told as children.” There are many more effects to overtraining and they don’t end up well. One of our previous articles, MMA: Effects On The Immune System, goes into more detail on a few of the other effects.

As an athlete it’s important to know your body and talk to your trainers about your training habits. Schedule a plan in training to make sure you don’t fall victim to some of the horrific effects of overtraining.
