Does anyone know when the forces will be higher/highest in the hip and knee joint? Thanks

Depends on the exercise. As far as the highest forces applied to the knee and hip, it would be jogging. We produce a huge amount of force to the knee and the hip, as much as three times our body weight of force is applied to the joint when contact is made during the forward stride. Hopefully that answers your question.

I am not sure what is meant by 3 times our bodyweight is applied to the joint. The ligaments in the joint, the tendons, the muscle and bone?


For instance, roughly 10 times the force in a bicep curl is actually being applied to the bone by the muscle due to the poor leverage based on the insertion of the biceps tendon on the forearm. In this respect, 3 times isnt much so I am just wondering what kind of forces you are talking about?

During a jump landing, 5-6 times your bodyweight is applied to the lower body in a purely kinematical sense but the individual forces on joints and bones by muscles varies based on indidivuals technique and varying limb lengths/muscle insertions.

What forces are you asking about....compressive, shear, torque...forces acting on muscles, tendons, ligaments, joint spaces??? The parameters are pretty endless and the best answer would be 'how long is a piece of string?'
