Most athletes need proteins and carbs to keep their bodies in shape. Different foods contain these and it is essential for the athletes to have the kind of foods. Protein is important for footballers to build, maintain and repair muscle. Foods that contain protein include Lean meats and poultry, Fish and seafood, Eggs, Low fat milk, cheese and yoghurt or soy products and Legumes and nuts. Too much fat in the diet can result in low energy levels and body fat gain.
Besides the fact that fats are the source of flavor to our food for many of us, fats are the main energy source for our body because a gram of fat obtains more energy than proteins and carbohydrates. A gram of fat contains of 9 calories while proteins and carbs contain only 4 calories per gram. Besides this, fat protects our organs, insulates us and keeps us warm, regulates our hormones. So, why do we want to cut eating foods that fat concentration is high on, despite the fact that fat is good for us? It is needed to be underlined that not all the fats are either good or bad.
ASSOCIATED HEALTH HAZARDS OF A HIGH SATURATED FAT DIET Good nutrition means eating the right foods in the right proportions, and being selective about how and what we consume, to provide a carefully balanced diet. A healthy diet should consist of protein, fats, carbohydrates, water, vitamins and minerals. A shortage of any of these constituents can cause deficiencies resulting in body malfunction. Over-nutrition can have a degenerate effect on the body as well. Lipids (fats) are a critical component of our daily diet in providing vital sources of energy.
Carbohydrate is the universal energy cell. Carbohydrate breakdown, glycogen serves as a source of glucose for your cells, your tissues, including your brain and muscles use glucose as a source of energy to support metabolic functioning. When your body requires glucose your liver and muscle breakdown their glycogen stores releasing glucose. Some glucose may be used directly in your liver and muscles while other glucose is released into your blood stream and used throughout body. Lipid break down, your body can breakdown triglycerides as a source of energy.
Taking more protein than your body needs will not help or benefit people at all, and can actually put a great deal of stress on your liver and kidneys. Beyond repairing tissue, protein is also used in the development of hormones and enzymes that will aid in the development of blood, skin, bone, and cartilage. For this reason, protein is an effective and safe way for building body mass when taken with a workout and also increases overall body fitness. Like any supplement being taken, it should be used properly and safely. The accurate amount of protein to ingest daily is one gram per each pound of body weight.
The definition of nutrition is the “basic physical resources necessary for energy production, growth, reproduction and the proper functioning of tissue and organs” (Webster-Gandy, Madden & Holdsworth 2012, p.2). The body’s requirements are met by the foods we eat; through the macronutrients and micronutrients we ingest and from the water we drink. Macronutrients are required in large quantities by the body and comprise of carbohydrates, proteins and lipids (fats) whilst the body requires fewer micronutrients that include vitamins and minerals (Rolfes, Pinna & Whitney 2012, p.3). All of these nutrients are key to helping the body move toward optimum health. Lipids and carbohydrates allow fuel to be utilised as energy, whilst proteins help maintain cells by growing and repairing them (Rolfes, Pinna & Whitney 2012, p.9).
This means that insufficient supply of amino acids in the body can limit the amount of protein it can use to build muscle. The best sources of protein rich foods would be coming from eggs, fish, meat, cheese, and milk. Certain vegetable proteins can be eaten together or with animal proteins to compliment with proper amino acid ratios. Sources like peanuts, kidney beans, lima beans, green peas, chick peas, lentils, eaten with bread, pasta, rice, and sesame seeds are part of complimentary proteins. Recommended amounts of protein vary because it depends on body weight, body composition, physical activity level and daily caloric intake.
(Swann, 2008) The pancreas also makes amylase (alpha amylase) to hydrolyse dietary starch into disaccharides and which are converted by other enzymes to glucose to supply the body with energy. Hypothesis: Most enzymes are very specific for a certain substrate. The active site on the enzyme molecule forms a keyhole into which the substrate fits like a key. The substrate molecule is then broken up into many smaller pieces. “The higher the reaction temperature, the more kinetic
Skeletal muscles are very important for such joints. • Circulation- Cardiac muscles provide the main force for circulation of blood throughout human body. The regular pumping of the heat keeps the blood in motion and nutrients are readily available to every tissue of human body. • Digestion -Only until the time the food reaches the throat it is voluntarily after which, the rest of movement of the food from throat to anus is involuntary and is performed by smooth muscles. The food is chewed in the mouth by the teeth using voluntary muscles but once it enters esophagus, it moves down the digestive tract through the process of peristalsis.
Enzymes are proteins that are used to speed up these reactions without being consumed by them. The activity of these enzymes can be altered by changing their environments, such as enzyme specificity (speed only a reaction that contains their substrate), increasing and decreasing temperature, concentration level, or adjusting the pH level. Catalase is a catalyst that digests potent hydrogen peroxide and converts it into H2O and O. It is due to this hydrogen peroxide digesting ability that we used catalase in this experiment. To record the role that environment plays in the reaction of an enzyme, we exposed the enzyme to various changes in temperature, concentration, and pH.
