Magnetic resonance imaging

I just thought that people may like to hear of this new development in the search for football talent and injury management.

I copied the following from various places on the web and made little changes here and there.

Magnetic resonance imaging (MRI) is a medical imaging technique used in radiology to form pictures of the anatomy and the physiological processes of the body in both health and disease. MRI scanners use strong magnetic fields, magnetic field gradients, and radio waves to generate images of the organs in the body. MRI does not involve harmful X-rays or the use of ionizing radiation, which distinguishes it from CT or CAT scans and PET scans.


It has been established that excellence in sports with short and long exercise duration requires a high proportion of fast-twitch or type-II fibers and slow-twitch or type-I fibers, respectively. Until today, the muscle biopsy method is still accepted as gold standard to measure muscle fiber type composition. Because of its invasive nature and high sampling variance, MRI would be much better.

There is a significant positive correlation between muscle carnosine, and percentage area occupied by type II fibers. Explosive athletes have ∼30% higher carnosine levels compared to the general population, whereas it is ∼20% lower than normal in typical endurance athletes. Similar results are found in young talents and ex-athletes. When active elite runners are ranked according to their best running distance, a negative sigmoidal curve was found between logarithm of running distance and muscle carnosine.

Muscle carnosine content shows a good reflection of the disciplines of elite track-and-field athletes and is able to distinguish between individual track running distances. The differences between endurance and sprint muscle types is also observed in young talents and former athletes, suggesting this characteristic is genetically determined and can be applied in early talent identification.

So what does this mean? If we want another explosive athlete like JJ we MRI scan all of the potential draftees and pick the one with the highest carnosine levels. People with higher muscular carnosine levels, although they can run much faster and more explosively, with their fast twitch muscles, tend to fatigue quicker.

MRI research is also looking into giving an automatic diagnosis on things like soft-tissue injuries. It will tell you the severity of the injury, the treatment required and the number of weeks the injury will take to heal. This will take the guesswork out of things.

Hope this is interesting. Might be better than the beep test.

Pity they don't have a medical test for football talent yet. :p

Apparently dogs can't do MRI's, but cats can. :cool:

Certain dogs can prepare the Lab reports though...
