简要总结
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.

结局指标
主要结局
Subjective Appetite
时间窗: 0-240 min
Measured by VAS questionnaire at 14 time points, used to calculate area under curve (AUC).( Composite measure)
Exercise intensity
时间窗: 60 minutes
Sixty minute exercise protocol at minutes 60 to 120. Oxygen consumption measured during exercise at 3 time points.
Plasma Glucose and Insulin Concentrations
时间窗: 0 - 240 min
Measured in blood using intravenous catheter at 14 time points, used to calculate area under curve (AUC). Glucose will be determined by automated methods using Abbot Spectrum CCX Analyzer, and Insulin will be measured by commercially available RIA kits. (Composite measure)
Food Intake
时间窗: at 120 min
Ad-libitum meal. Food consumed measured by weight.
