Soc24: Energy use, diet, nutrition and hydration Flashcards
Macronutrient
the types of food that you need in large amounts in your diet: carbohydrates, fats and proteins.
Carbohydrates
stored in the muscles and the liver as glycogen, which is quickly converted into glucose and used to provide energy.
Complex carbs
Complex carbohydrates (starch) are found in natural foods, such as bananas, brown rice, wholemeal bread, wholemeal pasta, nuts and potatoes. they provide a slower and longer-lasting release of energy
Simple carbohydrates
Simple carbohydrates (sugars) are found in their natural form in fruit and vegetables, and in their refined form in biscuits, cakes, chocolate and confectionery. They provide a short burst of energy
Fats
Provides energy
Protein
Proteins are important to help build muscles and to repair damaged tissue.
Proteins are particularly important to strength athletes, such as rugby players and shot and hammer throwers. Proteins are also used to provide energy during extended periods of exercise, such as marathon running, when all the carbohydrate has been used up.
Micronutrients
Micronutrients are the parts of your food that you need for normal growth, but only in small amounts - what we usually call vitamins and minerals.
Vitamins
Vitamins are essential for the body to function as they provide good skin, vision, teeth and bones.
Minerals
Essential for a healthy body. Calcium (for strong bones and teeth) and iron (for oxygen capasity of the blood) are 2 key minerals
Water
Water accounts for around half of your body weight. It holds oxygen and is the main component of many cells. It transports nutrients, waste and hormones around the body and controls the distribution of electrolytes (or body salts).
During exercise, your body sweats and loses electrolytes. Some isotonic drinks claim to replace these, but a balanced diet will also do this naturally. Water is also essential to control temperature.
Ectomorph
Thin , fast metabolism and struggles to gain weight
Endoporph
“Stocky” build with slow metabolism and struggles to loose fat
Mesomorph
Athletic, toned and gains muscle easier
