What Exercise Does for YOU! – increased cytosolic antioxidant levels.

We all know the benefits of cardiovascular exercise and anti-oxidants. They’re both great for our health and we can’t ever seem to get enough of them but did you know that your body creates and stores it’s own home made antioxidants when you exercise!?

“Regular physical exercise has many health benefits including a lowered threat of all-cause mortality along with a reduced risk of cardiovascular disease, cancer, and diabetes.” Says Jackson and Powers

Ok we knew that but “why?!” you ask?

Well “Muscle fibers contain both enzymatic and nonenzymatic antioxidants that work as a complex unit to regulate ROS. (Reactive Oxygen Species)”

So muscles create reactive oxygen species when they contract, our bodies are built to deal with this. Muscles create anti-oxidants to combat the oxidative stress that happens during exercise. Bodies are so COOL!

It should be further noted that the type of exercise utilized in the studies was “regular and chronic (long term)”also “intense or prolonged”. Given that we can grow our own antioxidants as an adaptation to exercise, I hope you all get up and go for a run!

See you in the next Episode of “What Exercise Does for YOU!”
