Abstract

The purpose of this study was to discern whether total grams of carbohydrate (CHO) consumed is associated with next day urine specific gravity (USG). Twenty-four Division I female collegiate soccer players with a mean age of 19.6 (SD=1.15) who were part of the team during pre-season summer training camp in August of 2019 volunteered to participate in this research. Athletes recorded food intake for six days during pre-season summer training camp. Food records were verified by a Board-Certified Specialist in Sports Dietetics and analyzed using NDSR. Athletes’ hydration statuses were evaluated using a daily assessment of USG, via spontaneous urine collection. A two-tailed Pearson correlation evaluated the impact of total grams of CHO intake per day on next day USG. Results indicated no significant relationship exists between total grams of CHOs consumed and changes in next day USG status (r= -0.131, p= 0.177, n= 107). Additionally, our study found that none of the athletes met their CHO needs on any given day. Within this sample of female NCAA Division I soccer players, no evidence of significant correlation was seen between total grams of CHO consumed and the next day’s USG. It may be beneficial for sports nutrition education strategies to focus on CHO’s benefits on hydration maintenance in the acute timeframe of 1-4 hours. Certainly, that does not mean to dismiss the encouragement of consuming the recommended amount of CHOs on a daily basis, but now we see that in terms of hydration we may not need to be as concerned about the previous day’s CHO intake.
