Describe one type of physical activity where a performer requires high levels of carbohydrates and water. - OCR - GCSE Physical Education - Question 19 - 2019 - Paper 1

One example of physical activity that requires high levels of carbohydrates and water is marathon running. Runners need substantial carbohydrates to fuel their extended endurance levels during long-distance runs. This type of exercise involves continuous, moderate to long-term physical exertion, which significantly depletes glycogen stores in the body.

Additionally, staying hydrated is crucial, as runners can lose a significant amount of water through sweat. To maintain optimal performance, they need to replenish both carbohydrates and water before, during, and after the race.
