Nutrient Timing
Nutrient timing is a sports dieting concept which suggests that time may be a missing dimension in improved Bodybuilding, muscular development. This concept represents a change over the previous school of thought that focused on Protein (nutrient), protein loading without emphasizing the synchronicity between eating and Exercise, exercising. Proper nutrient timing takes into account two dimensions that directly correlate to performance: # The consumption of the Substrate (biochemistry), substrates in ideal proportions. # The timing between exogenous fueling and exercise. When the right substrates are present at the ideal times, the result might be improved performance and growth. Nutrient timing may enhance performance of exercise, competition, and daily life expectations. The amount of each nutrient plays a role in performance and recovery. Recovery is essential to keep going in daily routines, competitions, and fitness in general. Fueling recovery and fitness may be enhanced by ...

Dieting
Dieting is the practice of eating food in a regulated way to decrease, maintain, or increase body weight, or to prevent and treat diseases such as diabetes and obesity. As weight loss depends on calorie intake, different kinds of calorie-reduced diets, such as those emphasising particular macronutrients (low-fat, low-carbohydrate, etc.), have been shown to be no more effective than one another. As weight regain is common, diet success is best predicted by long-term adherence. Regardless, the outcome of a diet can vary widely depending on the individual. The first popular diet was "Banting", named after William Banting. In his 1863 pamphlet, ''Letter on Corpulence, Addressed to the Public'', he outlined the details of a particular low-carbohydrate, low-calorie diet that led to his own dramatic weight loss. Some guidelines recommend dieting to lose weight for people with weight-related health problems, but not for otherwise healthy people. One survey found that almost half o ...

Bodybuilding
Bodybuilding is the use of progressive resistance exercise to control and develop one's muscles (muscle building) by muscle hypertrophy for aesthetic purposes. It is distinct from similar activities such as powerlifting because it focuses on physical appearance instead of strength. An individual who engages in this activity is referred to as a bodybuilder. In professional bodybuilding, competitors appear in lineups and perform specified poses (and later individual posing routines) for a panel of judges who rank them based on symmetry, muscularity, size, conditioning, posing, and stage presentation. Bodybuilders prepare for competitions through the elimination of nonessential body fat, enhanced at the last stage by a combination of extracellular dehydration and carbo-loading, to achieve maximum muscular definition and vascularity; they also tan and shave to accentuate the contrast of their skin under the spotlights. Bodybuilding takes a great amount of effort and time to r ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Protein (nutrient)
Proteins are essential nutrients for the human body. They are one of the building blocks of body tissue and can also serve as a fuel source. As a fuel, proteins provide as much energy density as carbohydrates: 4 kcal (17 kJ) per gram; in contrast, lipids provide 9 kcal (37 kJ) per gram. The most important aspect and defining characteristic of protein from a nutritional standpoint is its amino acid composition. Proteins are polymer chains made of amino acids linked together by peptide bonds. During human digestion, proteins are broken down in the stomach to smaller polypeptide chains via hydrochloric acid and protease actions. This is crucial for the absorption of the essential amino acids that cannot be biosynthesized by the body. There are nine essential amino acids which humans must obtain from their diet in order to prevent protein–energy malnutrition and resulting death. They are phenylalanine, valine, threonine, tryptophan, methionine, leucine, isoleucine, lysine, an ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Exercise
Exercise is a body activity that enhances or maintains physical fitness and overall health and wellness. It is performed for various reasons, to aid growth and improve strength, develop muscles and the cardiovascular system, hone athletic skills, weight loss or maintenance, improve health, or simply for enjoyment. Many individuals choose to exercise outdoors where they can congregate in groups, socialize, and improve well-being as well as mental health. In terms of health benefits, the amount of recommended exercise depends upon the goal, the type of exercise, and the age of the person. Even doing a small amount of exercise is healthier than doing none. Classification Physical exercises are generally grouped into three types, depending on the overall effect they have on the human body: * Aerobic exercise is any physical activity that uses large muscle groups and causes the body to use more oxygen than it would while resting. The goal of aerobic exercise is to increa ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Substrate (biochemistry)
In chemistry, the term substrate is highly context-dependent. Broadly speaking, it can refer either to a chemical species being observed in a chemical reaction, or to a surface on which other chemical reactions or microscopy are performed. In the former sense, a reagent is added to the ''substrate'' to generate a product through a chemical reaction. The term is used in a similar sense in synthetic and organic chemistry, where the substrate is the chemical of interest that is being modified. In biochemistry, an enzyme substrate is the material upon which an enzyme acts. When referring to Le Chatelier's principle, the substrate is the reagent whose concentration is changed. ;Spontaneous reaction : :*Where S is substrate and P is product. ;Catalysed reaction : :*Where S is substrate, P is product and C is catalyst. In the latter sense, it may refer to a surface on which other chemical reactions are performed or play a supporting role in a variety of spectroscopic and microscop ...

Exogenous
In a variety of contexts, exogeny or exogeneity () is the fact of an action or object originating externally. It contrasts with endogeneity or endogeny, the fact of being influenced within a system. Economics In an economic model, an exogenous change is one that comes from outside the model and is unexplained by the model. Such changes of an economic model from outside factors can include the influence of technology, in which this had previously been noted as an exogenous factor, but has rather been noted as a factor that can depict economic forces as a whole. In economic sociology, Project IDEA (Interdisciplinary Dimensions of Economic Analysis) gave notion to understanding the exogenous factors that play a role within economic theory. Developed from the International Social Science Council (ISSC) in the year of 1982, Project IDEA was founded to gather ideas from economists and sociologists in order to conceptualize what economic sociology incorporates, as they have sought ...

Anabolic Window
The metabolic window (also called the anabolic window or protein window) is a term used in strength training to describe the 15-minute (give or take, dependent on the individual) period after exercise during which nutrition can shift the body from a catabolic state to an anabolic one. Specifically, it is during this period that the intake of protein and carbohydrates can aid in the increase of muscle mass.Ivy, John & Portman, Robert. Nutrient Timing: The Future of Sports Nutrition'. Basic Health Publications, Inc., 2004. Currently there is not sufficient scientific evidence to support the metabolic window theory. The metabolic window is based on your body's anabolic response. Anabolism is when small molecules grow into bigger complex molecules. This is the opposite to catabolism, when larger molecules break down in the body. During anabolism, the molecules form into new larger cells and tissues. After strength training, your body is anabolic. This physical state requires a lot of ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Diets
The Low Countries comprise the coastal Rhine–Meuse–Scheldt delta region in Western Europe, whose definition usually includes the modern countries of Luxembourg, Belgium and the Netherlands. Both Belgium and the Netherlands derived their names from earlier names for the region, due to ''nether'' meaning "low" and ''Belgica'' being the Latinized name for all the Low Countries, a nomenclature that became obsolete after Belgium's secession in 1830. The Low Countries—and the Netherlands and Belgium—had in their history exceptionally many and widely varying names, resulting in equally varying names in different languages. There is diversity even within languages: the use of one word for the country and another for the adjective form is common. This holds for English, where ''Dutch'' is the adjective form for the country "the Netherlands". Moreover, many languages have the same word for both the country of the Netherlands and the region of the Low Countries, e.g., French ( ...
