This research study evaluates the feasibility and appropriateness of potatoes as an ergogenic aid in comparison to the currently promoted sports gels during a cycling challenge and time trial. Using a crossover design, trained cyclists will complete three separate cycling challenges and subsequent time trials in which they will consume either potatoes, commercially available sports gels, or water only.
The metabolic demands created by endurance activities, which include muscle and liver glycogen depletion as well as losses in body fluids and electrolytes, are significant limitations to the performance potential of the athlete. For this reason, a well-supported recommendation exists for such athletes to consume a carbohydrate formula, in particular, one containing electrolytes during their activity.
Currently, most commercially available exercise-nutrition products for use in endurance activities come at relatively high costs to the athlete. Moreover, the ingredients used within this market vary and could therefore hinder their effectiveness. For example, Fermentable Oligosaccharides Disaccharides Monosaccharides and Polyols (FODMAPs) potentially present in common sports foods (i.e. excess fructose) are known to alter gastrointestinal (GI) function in some individuals. Indeed, 25-70% of endurance athletes experience GI symptoms during exercise. Given the prevalence of exercise induced GI discomfort in this population, it is possible that GI symptoms limit the adherence to nutritional recommendations during exercise. Therefore identification of a targeted nutrition strategy that maximizes GI effectiveness and dietary adherence is warranted.
An alternative to the commercially available sports foods are whole foods. Specifically, white potatoes, which have a high GI index, indicates that their carbohydrate content is readily available. Additionally, potatoes naturally contain potassium, an important electrolyte. Because of these characteristics, potatoes provide the potential to be a low-cost alternative, and merit investigation. To this point, we know of no studies that have explored the effectiveness of white potatoes as an ergogenic aid. Therefore, the purpose of this study is to examine how capable potatoes are at off-setting the losses in muscle and liver glycogen and electrolytes compared to the current products available on the market, i.e. "sports gels."

Water Intervention: In one of the 3 cycling trials, participants will receive only water and no carbohydrate supplementation during the 2 hour cycling challenge.
Dietary Supplement: Water
Carbohydrate Gel Intervention: In one of the 3 cycling trials, participants will receive carbohydrate supplementation in the form of commercially available gels (15g every 15 minutes) during the 2 hour cycling challenge.
Dietary Supplement: Carbohydrate Gel
Potatoes Intervention: In one of the 3 cycling trials, participants will receive carbohydrate supplementation in the form of pureed russet potato (15g every 15 minutes) during the 2 hour cycling challenge.
Dietary Supplement: Potatoes
Pureed russet potatoes will be used as a carbohydrate supplement for participants during one of the three cycling challenges.
Commercially available PowerBar PowerGel will be used for the carbohydrate gel condition during one of the three cycling challenges.
Water will be used as a control during one of the three cycling challenges (participants will not receive any carbohydrate supplementation).

Ran from Sep 2017 to primary completion in Sep 2019, 24 months.
Of 5,147 non-industry interventional studies with no phase under Motor Activity, half reached primary completion within 17 months of starting (the median), counting those still running; a quarter within 7 and three quarters within 36. This study's 24 months is above that.
Counting every sponsor, half of 5,207 studies reached it within 17 months; a quarter within 7 and three quarters within 36.
