What a load of BS! If that were the case you would expect almost all runners to be plagued with injuries which is simply not the case. Yes running exposes the locomotor system to greater forces that can cause injury than say walking does but being exposed to forces and making adaptions are a normal part of living. In fact those very stressors are actually good for us and make us stronger and become more resilient as lomg as they are in the right dosage and don't overload our system.

If you have good motor skill, train properly on good surfaces with good shoes and don't overdo it you may never have an injury. Running and sprinting are normal variations on locomotion when the demand for speed are high. We evolved to be able to run in order to hunt and avoid becoming Sunday roast.

Problems may occur because we do so little running in real life, then undertake excessive amounts when we lack good skill and our musculoskeletal tissues have not develped through adaption to the stress of running. Or we get obsessed with over exerting our limits.

If you want to talk about something that is really dangerous then look sitting on our tush all day. That is a real health risk and many more of us do that than run.
