Case Study Anne participates in triathlons. Recently, in a half-Ironman race, she experienced nausea, intestinal cramping, and diarrhea on the run, leading to a poor performance. The entire race took her nearly 61⁄2 hours. During the bike portion, she consumed 100 oz of a relatively new sports beverage that she has been training with this year, as well as two gels. On the run, she consumed sips of the sports beverage provided on the course but switched over to water once she started experiencing the nausea, cramping, and diarrhea. She was frustrated by her performance and wants to ensure that it does not happen again. You ask Anne to bring in the new sports beverage she has been consuming so that you can review the Supplement Facts label. Per 8-oz serving, the following nutrients are provided: 60 calories, 15 g carbohydrates, 0 g protein, 0 g fat, 100 mg sodium, 50 mg calcium, 30 mg magnesium, and 100 mg potassium. Questions What could be a potential cause of Anne’s nausea, intestinal cramping, and diarrhea during the race? What recommendations would you give to Anne to prevent the symptoms from occurring in future races?
