We studied polygraphically the sleep in lui healthy male volunteers (26 - 35 years old; mean age 29.4) lying in a common anti-sore bed for three days. Then, after a 4 day .suspension of the treatment, the same subjects were again monitored during sleep for a further 3 day period in a simulated microgravity condition. The obtained results were analized using the Wilcoxon's test. The results of the present study show a statistically significant difference between the recording during the initial three day period, i.e. when the subjects were sleeping in the anti-sore bed, with respect to the one during the simulated microgravity period In particular, the following measured parameters appeared changed: total stage 1 night III (p 0.01), total REM night I and II (p 0.001), REM latency night I and III (p 0.01), stage 1 latency night m (p 0.02), spindiling index night III (p 0.02).
