简要总结
Several previous studies have shown that repeatedly ingesting carbohydrate supplements during exercise training sessions, over a period of days and weeks, can gradually increase carbohydrate oxidation and reduce gut discomfort during exercise. However, repeatedly ingesting large amounts of carbohydrate during training sessions can be burdensome and can cause gut distress. Thus, it would be advantageous if the same long-term benefits could be realized from consuming these carbohydrate supplements at rest instead of specifically during training sessions. Therefore, the goal of this study is to examine whether repeatedly ingesting a carbohydrate-rich beverage at rest over a 5-day period alters metabolism and gut symptoms while ingesting carbohydrate during exercise.

结局指标
主要结局
Change in Hydrogen Breath Production
时间窗: Samples will be collected before after a 60-minute run at a baseline visit and at a second visit after ingesting the carbohydrate or placebo beverage for 5 days.
Samples of expired air will be tested for hydrogen levels, a marker of carbohydrate malabsorption
Change in Gastrointestinal Symptom Ratings
时间窗: Symptoms will be collected during a 60 minute run on a treadmill at a baseline visit and at a second visit after ingesting the carbohydrate or placebo beverage for 5 days.
Symptoms such as nausea, fullness, belching, reflux, abdominal cramps, flatulence, and urge to defecate will be recorded on a 0-10 scale (0 = no discomfort, 10 = unbearable discomfort).
次要结局
- Change in Feeling Scale(Ratings will be collected collected before and during each 60-minute run at a baseline visit and at a second visit after ingesting the carbohydrate or placebo beverage for 5 days.)
- Change in Carbohydrate Oxidation(Respiratory gases will be collected during each 60-minute run at a baseline visit and at a second visit after ingesting the carbohydrate or placebo beverage for 5 days.)
