Which statement is true regarding how muscle activation affects
bone loading?
Contraction of the tibialis anterior would produce a bending force on
the tibia, with compressive forces on the posterior side.
Muscle contractions do not affect bone loading.
Contraction of the calf muscles would produce a bending force on the
tibia, with compressive forces on the posterior side.
Contraction of the tibialis anterior would produce a shear force on the
tibia.
Contraction of the calf muscles would produce a bending force on the
tibia, with compressive forces on the anterior side.
