Description:
Nineteen volunteers in bed with head down tilt (-6 deg) for 1 month and doing or not exercise training while in bed (lido or ergometer) had their limb muscle studied by magnetic resonance spectroscopy. A protocol of repetitive exercise in the magnet was set and a wooden probe designed to support the limb and to allow exercise. Spectra were recorded continuously during the protocol. In each spectrum, inorganic phosphate, phosphocreatin, adenosin triphosphate, and pH were measured. All the subjects were studied before, after bedrest, and 6 weeks later. After 1 month, the lido group show no changes in the spectra of their leg muscles while the group doing no exercise or ergometer do. For the arms, a loss of muscle function is only seen in the group doing no exercise.
