- Abstract
We developed a “hybrid exercise” technique that uses the force generated by an electrically stimulated antagonist muscle to provide resistance to a volitionally contracting agonist. In other words, the agonist performs a volitional concentric contraction against an electrically stimulated eccentric contraction of the antagonist. Hybrid exercise has several advantages. These include; 1) activation of type I muscle fiber as a result of the volitional contraction of agonist muscles, 2) simultaneous exercise both agonist and antagonist musculature, 3) longitudinal bone force loads, 4) requiring minimal external stabilization of the subjects , and 5) the proven safety of the electrical stimulation as a physical therapy modality. Hybrid exercise, which utilizes electrically stimulated antagonist force as a resistance of joint motion instead of the gravity, would become a useful exercise method in the weightlessness environment.
