Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Participants (16 women) will be instructed to eat a standard dinner the day before, to consume a standard breakfast at home after overnight fast, and to report to the laboratory, where the test meal will be administered 4 h after breakfast. Studies will be conducted in a quiet, isolated room. Participants will be taught to produce diaphragmatic contraction and visible abdominal distention. A probe meal up to maximal satiation will be administered to induce abdominal fullness/bloating sensation; immediately after ingestion, bloating sensation (from 0 to 10) and digestive well-being (from -5 to +5) will be scored during 8 alternating episodes (30 s each) in random sequence of diaphragmatic contraction (abdominal distension) versus diaphragmatic relaxation.
