The Effect of a Pre-meal Snack and/or Exercise on Post-prandial Glycemic

Status Completed

Clinical Trial Summary

The investigators aim to test the feasibility and effectiveness of a pre-meal snack to reduce the postprandial glycemia (PPG) excursion after a breakfast consumption in adult patients with cystic fibrosis (CF). The investigators also want to investigate the impact of a postprandial exercise to reduce the PPG excursion. An improvement in PPG excursions can improve the condition of CF patients primarily by delaying the onset of cystic fibrosis related diabetes (CFRD) and / or by reducing the risk of lung function loss.

Clinical Trial Description

The investigators are proposing a randomized pilot study to explore the impact of a soy beverage of carbohydrates and protein early in the morning, to stimulate and initiate secretion of Insulin to reduce PPG excursions of the following a lunch in adult patients with CF. Investigators will also study the impact of a post meal exercise on the PPG excursion. Fourteen participants will be included and will each perform a 4-hour intervention in cross over design according to those 4 following experimental conditions: 1. Consumption of 200ml of water (flavored) + breakfast of 90g of carbohydrates (CHO) for men and 80g for women; Sedentary activities throughout the study [condition control] 2. Consumption of 200ml of soy beverage + 90g of carbohydrate (CHO) breakfast for men and 80g for women; Sedentary activities throughout the study [snack effect on PPG excursion] 3. Consumption of 200ml of water (flavored) + breakfast of 90g of carbohydrates (CHO) for men and 80g for women + physical activity practice (3min walk at 60% VO2max every 30 minutes, x5); [exercise effect on the PPG excursion] 4. Consumption of 200ml of soy beverage + breakfast of 90g of carbohydrate (CHO) breakfast for men and 80g for women + physical activity practice (3min walk at 60% VO2max every 30 minutes, x5). [Combined snack and exercise effect on the PPG excursion] Main result: plasma glucose area under the curve. The underlying mechanisms, insulin, incretin hormones (GLP-1 and GIP), acceptability and side effects (mealtime hyperglycaemia) should also be measured. At the end of this pilot project, the investigators will have established a pre-meal snack and/ or postprandial exercise have a positive impact on PPG. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
