growth/size/body

decreased body weight ( J:316008 )

• body weight is slightly decreased

• however, weight of the gastrocnemius muscle is not different

muscle

abnormal muscle physiology ( J:316008 )

• maximum isometric torque normalized by the whole weight of the plantar flexor muscles is decreased

• passive stiffness of tibialis anterior muscle fibers is decreased

• however, post-tetanic potentiation is unchanged in plantar flexor muscles and calcium-activated force in anterior muscle fibers is unchanged
