Effect of the moderate exercise on performance in upper/lower limb during long term bed rest.
The purpose of this study was to investigate that considers the influence of the moderate exercise has on the upper limbs and the legs during 21 days head down bed rest. Therefore motor evoked potential (MEP) induced by transcranial magnetic stimulation (TMS) in lower leg muscles of four healthy subjects were investigated before/after and during bed rest. There were no significant differences statistically between soleus MEPs before and after bed rest in all subjects. However there were decreased tendancy in MEPs during non-exercise group. And then there were not change discriminal ability on differential threshold of weight sensory in scale test in all subjects during head down bed rest. Theses results indicate that the assign cognitive performance, sensory in scale for upper limb no changes during and after head down bed rest.
