Effect of Constraint Loading on the Lower Limb Muscle Forces in Weightless Treadmill Exercise

Figure 2

Inverse dynamic model of human musculoskeletal system and the diagram of loading conditions. The lower limbs of the model contain 6 joints and 318 muscles. (a) The model was in the condition of normal gravity. (b) The model was in the condition of weightlessness; the body was restrained with the bungee cords, which provide the vertical loading instead of the gravity effect.
