Conditions diabetes, obesity
Treatments control, small particle size pea flour, large particle size pea flour, lentil flour, navy bean flour, pinto bean flour
Sponsor University of Manitoba
Collaborator Saskatchewan Pulse Growers
Start date August 2015
End date June 2017
Trial size 30 participants
Trial identifier NCT02402517, B2014:114-2


The objectives are to test the acute effects of different extruded pulse snacks on: 1) aerobic endurance and substrate oxidation during exercise 2) response of blood glucose, insulin and appetite on an aerobic exercise session, and 3) food intake two hours following the exercise session. The investigators hypothesize that consumption of food products containing pulse ingredients 60 minutes before exercise will increase aerobic endurance (lower oxygen consumption), decrease carbohydrate oxidation (greater respiratory quotient), and a reduction in lactate production during compared to the same exercise session following the ingestion of a non-pulse food. The investigators also hypothesize that consumption of extruded pulse snacks will lead to lower blood glucose, insulin, appetite and food intake, suggesting lower calorie compensation, following a 60-minute aerobic exercise session compared to the same exercise session following the ingestion of a non-pulse food.
