Abstract/OtherAbstract:
PURPOSE: Comparatively few prospective studies have investigated the relationship between physical activity and gallbladder motility, and the results are controversial. Exercise may affect gallbladder motility via neural or hormonal mechanisms. The purpose of this study was to evaluate the possible effects of aerobic exercise on gallbladder motility in a group of obese women without gallstones. PATIENTS AND METHODS: Twenty-three obese women (age 41.2+/-10.3 years, body mass index 40.7+/-6.7 kg/m(2)) were included in the study. Following an overnight fast, fasting and postprandial (15, 30, 45, 60, 75, 90, 120, and 150 minute) volumes and ejection fractions were evaluated with real-time ultrasonography before exercise. For all subjects, the exercise regimen consisted of daily 45-minute walking sessions at 60-80% of maximum heart rate for 4 weeks except weekends. Gallbladder volume and ejection fraction were again evaluated after exercise. RESULTS: Fasting and postprandial (15, 30, 45, 60, 75, 90, 120, and 150 minute) volumes were 38.6+/- 10.9, 32.8+/- 8.8, 27.6/- 8.1, 22.7+/- 8.5, 21.4+/- 7.2, 20.8+/- 7.0, 22.8+/- 7.3, 29.6 +/- 7.0, and 36.8+/- 6.2 cm(3) before the exercise period, respectively, and 40.8+/- 18.9, 29.9+/-11.2, 25.3+/- 9.2, 22.4+/-8.5, 19.6+/-7.8, 17.7+/- 6.8, 17.8+/- 7.3, 23.1+/-10.8, and 29.0+/-14.4 cm(3) after the exercise period, respectively. Postprandial (15, 30, 45, 60, 75, 90, 120, and 150 minute) ejection fractions were 13.5+/-15.9, 27.4+/-15.4, 39.5+/-20.0, 43.2+/-16.7, 44.3+/-17.3, 37.5 +/- 23.5, 23.5 +/-25.1, and 5.5+/- 21.6% before the exercise period, respectively, and 22.6+/- 20.1, 34.6+/-14.5, 42.0+/-13.6, 49.2+/-12.6, 53.1+/-14.1, 52.6+/-16.1, 43.6+/-17.0, and 29.2+/- 26.5% after exercise, respectively. After the exercise period, the 75, 90, 120, and 150 minute volumes were lower (p< 0.05, p< 0.05, p< 0.05, p< 0.01) and the 90, 120, and 150 minute ejection fractions were higher than before exercise (p< 0.05, p < 0.05, p< 0.01). CONCLUSIONS: Our study showed that exercise decreased late-phase postprandial gallbladder volume and increased late-phase postprandial gallbladder motility in these obese women.
