2000), and the antigravity muscles located in the lower extremity have a greater influence of decreased mechanical loading conditions such as bed rest, limb immobilization, and space flight (Kanehisa, 2005).
With gravity compensation, the amplitude of the sEMG decreased especially in the antigravity muscles.
The results confirmed our presumption based on previous studies with nondisabled elderly [10] and stroke patients [11,13,15] that also showed a decreased sEMG in antigravity muscles and unaffected timing.
Many of these experiments probed adaptations of the so-called antigravity muscles, which support the body and maintain posture in Earth's gravity.
