IGCSE Physical Education Practice Exam

Nutrients required for health and performance come from what you eat and drink. The diet supplies energy and the building blocks your body needs for growth, repair, and daily functions. Carbohydrates fuel workouts, protein builds and repairs muscles, fats provide long-lasting energy and essential fats, vitamins and minerals support metabolism, immunity, and bone health, and fluids keep you hydrated. Because of this, the component focused on diet is the source of nutrients that support health, fitness, strength, and wellbeing.

Exercising improves health and fitness by challenging the body, but it doesn’t provide the nutrients themselves. Rest helps recovery and energy restoration, while work relates to motivation and resources rather than supplying nutrients.
