Carbohydrates are a collection of biological molecules that provide the body with its main source of energy. For GCSE PE, understanding these vital functions is key to explaining how the body fuels physical activity, from quick sprints to endurance events. Carbohydrates are broken down into glucose, which is then used for respiration to produce energy.

According to the NHS, around one-third of the food you eat should be starchy carbohydrates. A balanced diet, a key topic for GCSE PE students, is defined as a diet that contains the correct proportions of carbohydrates, fats, proteins, vitamins, minerals, fibre, and water necessary to maintain good health. It is essential for providing the energy needed for physical activity and supporting overall wellbeing.

Studies reveal that a significant proportion of athletes, even those in sunnier climates, suffer from vitamin D insufficiency, potentially hindering performance and increasing injury risk. For GCSE PE students, grasping what vitamin D does is essential for understanding the link between nutrition, health, and athletic achievement.
