Energy Use, Diet, Nutrition and Hydration – GCSE Physical Education Edexcel Revision

Topic: Energy Use, Diet, Nutrition and Hydration

Understanding the body’s energy requirements is crucial during physical activity. The body primarily uses carbohydrates, fats, and proteins for energy.
Carbohydrates and fats serve as the main sources of energy. They provide fuel for physical endeavors and aid in digestion and absorption of nutrients.
Proteins are vital for muscle repair and growth, enhancing performance and strength. They are not typically used as the primary energy source.
A balanced diet is essential for peak performance. This includes adequate quantities of different food types: proteins, fats, carbohydrates, vitamins, and minerals.
Diets should be adjusted to accommodate the specific demands of different sports. For instance, endurance athletes often require a higher carbohydrate intake, while strength athletes require more proteins for muscle recovery.
Staying adequately hydrated is paramount. Dehydration can negatively impact performance, causing fatigue and reducing endurance.
Fluid needs can differ depending on the intensity and duration of exercise and the temperature of the environment. Ensure to adjust fluid intake accordingly.
Not only is water intake important, but also the consumption of electrolytes, as these are lost through sweat during exercise and need to be replaced.
Vitamins and minerals are necessary for a multitude of body functions, including energy production, bone health, and immune function. They should be present in the diet in correct amounts.
Over-nutrition or under-nutrition both can have detrimental effects on performance and recovery. Maintaining a well-balanced diet is essential.
Consume a pre-exercise meal 2-3 hours prior to training or competition to provide energy.
Post-exercise, replenishing energy stores quickly is important. Consuming carbs and proteins within 30 minutes after exercise aids in recovery.
Remember that everyone is unique, and diet should be personalized to meet individual needs, preferences, and goals. While these general guidelines can assist, working with a registered dietitian can provide a detailed, tailor-made nutrition plan.
