Fig. 2. Qualitative physiologically adaptive changes of EMG and L5
afferent activities during 14 days of hindlimb unloading (HU) and recovery.
(A) Qualitative representations of the right soleus EMG activity and the right
L5 afferent neurogram at the pre-suspension level, at the beginning
of the HU period (D0) and on the third (D3), ninth (D9) and fourteenth (D14)
days of HU. (B) Qualitative representations of the right soleus EMG activity
and the right L5 afferent neurogram on the first (RD0), third
(RD3), ninth (RD9) and fourteenth (RD14) day of recovery.
