Responses of skeletal muscles to gravitational unloading and/or reloading

Table 1 Responses of fiber properties in rat soleus to functional overloading (FO), hindlimb unloading (HU), and deafferentation with (DA+FO) or without FO (DA) vs. normal cage controls

Functional overloading was performed by ablation of the distal gastrocnemius and plantaris tendons. Deafferentation was performed at the fifth level of the spinal cord. Cited from [51]
