| Outline of Final Research Achievements |
Hybrid training System (HTS) is to create resistance to the motion of a volitionally contracting agonist muscle by means of the force generated by its electrical stimulated eccentric antagonist muscle. We developed the new training method that HTS is combined with a cycle ergometer (HCE). HCE stimulated acute increases in growth hormone, lactate and IL-6 than conventional ergometer at the same workload. Moreover, HCE improved the peak oxygen uptake and knee muscle strength with the training program used in orbit (30-min HCE at a 3-time session a week for 6 weeks ). The change of knee extension strength by HCE was greater than by a ergometer exercise without HTS. We simulated that HCE effectively increased the oxygen uptake in a linear manner, and additional stimulation of muscles at the ankle joint increased the oxygen uptake. In the flight experiment, we confirmed that HCE was performed without a problem. HCE seems to be a useful method in orbit or space flight.
