The Secret Benefits Of Running Long Marathons
For all of you runners out there you will be very pleased to find out that a new study on running that was presented at the European Congress of Endocrinology showed that running has more benefits than you knew before. It was previously thought that because running is a high impact exercise it would hurt the joints and may cause long term joint problems, especially with old age. This new study shows that while running may but a greater strain on your bones than low impact exercise workouts is good for your bone health in the future and this is especially true when compared to non-load bearing or weight lifting exercises. That’s right, running may very well be good for your joints in the long run. Who would have thought?
The study that was performed and it compared a group of extreme runners to a group of people who did no running at all or did a little bit of exercise like moderate physical activity instead of racing. The study was focusing on a few hormones that help to regulate metabolism and energy in the body, these being glucagon, leptin, and insulin. The study also focused on two different bone proteins, these being osteocalcin and P1NP. The researcher involved took tests to see what the levels of all of these things were in the bodies of the runners before and after a 65 kilometer run and compared that to a group of people who only did some slight exercise to get the blood flowing.
The results of this study were very interesting indeed. After the 65 kilometer run the extreme marathon runners had much higher levels of glucagon in their blood than the group of people that didn’t do the big run. This shows that the runner had a higher demand for energy. The runners also had lower levels of both insulin and leptin in their blood and this would indicate that the runners had a lower energy level than the control group after the run. Furthermore the levels of bone protein also decreased more for the runners when compared to the light exercisers. The lower levels of osteocalcin and P1NP right after the race indicates that the runners are actually using their energy to increase their metabolism instead of using it for bone formation. Well these are facts that were known before, but there is one thing that was not known and that is the most important part.
The number one thing that the research study found was that the extreme marathon runner had much higher levels of P1NP in their blood while at rest and not exercising than the group that did not exercise. This may not sound like much after the previous findings, but it is in fact very important. This is because the runners seem to not be using their energy to increase bone mass while running, but their bone mass does increase a lot more while at rest.
