Consuming carbohydrates before exercise tops off muscle glycogen stores and sustains blood glucose for improved endurance and performance.
What percentage of daily caloric intake is generally recommended to come from carbohydrates for active individuals?
Answer: 45–65%

Dehydration of as little as what percentage of body weight can impair athletic performance?
Answer: 1–2%
A fluid loss of just 1–2% of body weight can reduce endurance performance, impair cognitive function, and increase perceived effort.
