Sports nutrition is the study and practice of nutrition and diet for maintaining and improving athletic performance. Nutrition is part of many sports training regimens, being used in strength sports (such as weightlifting and bodybuilding ) and endurance sports (e.g., cycling , running , swimming , rowing ).
Nutritional science is often combined with food science (nutrition and food science). Trophology is a term used globally for nutritional science in other languages, in English the term is dated. Today, it is partly still used for the approach of food combining that advocates specific combinations (or advises against certain combinations) of food.
Specific dynamic action (SDA), also known as thermic effect of food (TEF) or dietary induced thermogenesis (DIT), is the amount of energy expenditure above the basal metabolic rate due to the cost of processing food for use and storage. [1]
Preventive Nutrition is a branch of nutrition science with the goal of preventing, delaying, and/or reducing the impacts of disease and disease-related complications. [ 1 ] [ 2 ] It is concerned with a high level of personal well-being , disease prevention , and diagnosis of recurring health problems or symptoms of discomfort which are often ...
The roots of periodization come from Hans Selye's model, known as the General adaptation syndrome (GAS). The GAS describes three basic stages of response to stress: (a) the Alarm stage, involving the initial shock of the stimulus on the system, (b) the Resistance stage, involving the adaptation to the stimulus by the system, and (c) the Exhaustion stage, in that repairs are inadequate, and a ...
Within each cycle, the time period during which the process is more active is called the acrophase. [4] When the process is less active, the cycle is in its bathyphase or trough phase. The particular moment of highest activity is the peak or maximum; the lowest point is the nadir. How high (or low) the process gets is measured by the amplitude.
Primary nutritional groups are groups of organisms, divided in relation to the nutrition mode according to the sources of energy and carbon, needed for living, growth and reproduction. The sources of energy can be light or chemical compounds; the sources of carbon can be of organic or inorganic origin.
Food scientists working in Australia A food science laboratory. Food science (or bromatology [1]) is the basic science and applied science of food; its scope starts at overlap with agricultural science and nutritional science and leads through the scientific aspects of food safety and food processing, informing the development of food technology.
