Abstract

AIM: To observe the change of EGG and to study the effect of simulated weightlessness on gastric motility.

METHODS: The weightlessness model was made by lying on bed with head down tilt -6° for 21 d. EGG was recorded in 15 volunteers before and after meal using an ambulatory EGG.

RESULTS: The results showed that nausea, pain and loss of appetite appeared initially and weight of body declined significantly (P < 0.01). Bradygastria (< 2.4 cpm) increased apparently after 8 d bedrest. There was significant difference (P < 0.05) between preprandial and postprandial proportion of bradygastria using paired t test. The dynamics parameters of bradygastria declined significantly and bradygastria rhythm increased with duration of bedrest.

CONCLUSION: Simulated weightlessness caused gastric rhythm and gastric motility declining.
