at my place of work we were made aware of the potential risks of RSI (Repetetive Strain Injury). when i got home that evening, i took my dog for a walk and started to think about RSI, for no reason in particular. i put this question forward to the public, why dont we get RSI from walking or moving our arms, we must spend hundreds of hours of our lives walking, surely after a few years it should take its toll on our bodies, long before old age.
just wondering

So where’s the strain? When you walk, you move your arms and legs in a leisurely fashion, without much resistance. However, if you run, you may suffer a leg strain somewhere, and this is common in runners. Running uses the hamstring significantly, and this is a common source of strain. Calf strains and Achilles’ tendon strains also are common. Those strains are unlikely by walking. The force of your foot hitting the ground in running is much greater than in walking.
Actually, I have felt some strain in my upper arms by running, as I’m increasing my distance now, and the repetitive action of my arms is causing a minor ache, but nothing serious. Doesn’t even bother me playing tennis or serving.
Sure ,joggers get strains all the time. Why we have low impact exercises.
