Why is high force exertion harmful?
The exertion of force requires high muscle forces. This may lead to an acute overloading and/or fatigue of muscles. During such work high forces also occur in the skeletal system. This may lead to an acute overloading and injury of the skeletal structures. Force exertion, where the force acts distantly from the body, bears a high risk of damage to the lumbar spine tissues. For tasks with long-lasting or frequently repeated high force exertion, there is risk of degenerative diseases especially of the lumbar spine.
