Title   Osteoarthritis from long-distance running?
Full source     Sportverletzung - Sportschaden, 2005, Vol 19, Iss 2, pp 89-93

Long distance running has become a fashionable recreational activity. This 
study investigated the effects of external impact loading on bone and cartilage 
introduced by performing a marathon race. Seven beginners were compared to six 
experienced recreational long distance runners and two professional athletes. 
All participants underwent magnetic resonance imaging of the hip and knee 
before and after a marathon run. Coronal T1 weighted and STIR sequences were 
used. The pre MRI served as a baseline investigation and monitored the training 
effect. All athletes demonstrated normal findings in the pre run scan. All but 
one athlete in the beginner group demonstrated joint effusions after the race. 
The experienced and professional runners failed to demonstrate pathology in the 
post run scans. Recreational and professional long distance runners tolerate 
high impact forces well. Beginners demonstrate significant changes on the post 
run scans. Whether those findings are a result of inadequate training (miles 
and duration) warrant further studies. We conclude that adequate endurance 
training results in adaptation mechanisms that allow the athlete to compensate 
for the stresses introduced by long distance running and do not predispose to 
the onset of osteoarthritis. Significant malalignment of the lower extremity 
may cause increased focal loading of joint and cartilage.
