Outline of Final Research Achievements |
A hybrid training system (HTS) combines the electrical stimulation of antagonist muscles with volitional contraction of agonist muscles. We determined a technological way to reduce discomfort and high muscle contraction force induced by low-intensity electrical stimulation on antagonist muscles considering the potential of the HTS. The magnitude of oxygen uptake and joint reaction forces during ergometer exercise at 1 g and 0 g was predicted under varying exercise conditions and stimulus intensity using a musculoskeletal model with the HTS. We confirmed that the HTS can easily control the magnitude of oxygen uptake and joint reaction forces and realize a magnitude like that of daily activity on Earth during ergometer exercise at 0 g. Optimal cycling conditions to achieve desirable values for oxygen uptake and joint reaction forces can be established for health maintenance and creating exercise programs in constrained spaces.
