How much do you know about sports nutrition foods?

Hengkang Biomedicine focus on sports nutrition food for 20 years, do you understand what is sports nutrition food?

I. Definition

Food specially processed to meet the physiological and metabolic status, exercise capacity and special needs of certain nutrients of people who participate in physical exercise 3 times a week or more, each time the duration of 30 minutes or more, each exercise intensity of medium or more).

Ii. Classification

1, according to the classification of characteristic nutrients (sports nutrition food designed for different needs of energy and protein, etc.), divided into three categories.

A. Energy supplement: sports nutrition food with carbohydrates as the main component that can quickly or continuously provide energy. Carbohydrates provide no less than 60% of the total energy of the product. Such as: power drink

The energy metabolism of human body during exercise has the characteristics of high intensity and high consumption rate, which can reach two or three times or even more than one hundred times the level of energy consumption at quiet time. Timely replenishment of energy during exercise is necessary to ensure a given intensity of exercise, and helps delay exercise fatigue and prevent sports injuries. Therefore, the energy value of this kind of product is the key index.

Carbohydrates are the best source of energy, fast production, and can also release energy through glycolysis in the case of hypoxia, which is very important for people engaged in high-intensity exercise and the body is relatively hypoxic. In addition, sugar is a major energy source for the central nervous system and helps protect the liver from toxic substances. Carbohydrate supplementation before exercise can increase muscle glycogen reserve, maintain blood sugar concentration and insulin level, and reduce protein consumption during exercise; Supplement of carbohydrate after exercise can promote physical recovery and enhance the synthesis and storage of liver and muscle glycogen.

B. Energy control: sports nutrition foods that can meet the needs of exercise weight control, including two kinds of promoting energy consumption and energy replacement. The proportion of energy provided by protein in the total energy of the product is between 25% and 50%. For example: protein shake

For sports people who control their weight through exercise, especially those who must control their weight or reduce their weight under specific circumstances, simply reducing diet will lead to insufficient intake of water, minerals and vitamins in the body, which will cause damage to physical fitness and physical health if not supplemented in time. Energy control sports nutrition food is specifically formulated for the needs of such people to meet the needs of exercise weight control food, such food can also add the nutrients required by the exercise population to maintain the normal physiological function of the body. Promote Energy Expenditure products meet exercise weight control needs by adding nutrients that promote energy expenditure during exercise. These products can be selected as nutritional supplements or nutrients that contribute to energy expenditure during exercise. These substances can promote energy consumption through the transfer of fatty acids. Energy replacement products must add protein according to nutritional needs, and non-energy nutrients (such as vitamins and minerals) required for exercise can be added to maintain normal exercise ability.

The main ways to control energy are to promote energy expenditure and reduce energy intake through meal replacement with low energy density products. This standard divides controlled energy into products that promote energy consumption and products that replace energy.

C, supplementary protein: with protein/or protein hydrolysate as the main component, can meet the needs of body tissue growth and repair of sports nutrition food. The proportion of energy provided by protein in powdered products is not less than 50% of the total energy.

High intensity exercise causes the breakdown of muscle protein to different degrees, which further increases the demand for protein in the exercise population. In order to repair damaged muscle protein, the intake of adequate amounts of protein or its hydrolysate helps to repair the body tissue and improve the necessary raw materials for muscle synthesis. Therefore, protein is often widely used as a key nutrient for maintaining and building muscle strength during exercise or training. Such as: whey protein, positive nitrogen protein, isolated whey protein, muscle excitation matrix protein, protein bar

Protein hydrolysates are substances obtained from proteins under the action of acidic substances or proteolytic enzymes. Each protein hydrolysate contains peptides of different lengths and free amino acid molecules, depending on the degree of hydrolysis. Studies have shown that the main effects of protein hydrolysates are reflected in the following aspects: (1) significantly improve muscle strength and increase lean body mass; (2) Taking drinks with protein hydrolysate during exercise can effectively reduce muscle fatigue; (3) Promote the synthesis of muscle glycogen; (4) Promote insulin secretion and muscle protein synthesis.

2, according to the classification of sports (sports nutrition food designed for the special needs of different projects), divided into three categories.

D, speed and strength: creatine as the characteristic component, suitable for sprinting, jumping, ball, weightlifting, wrestling, judo, taekwondo, bodybuilding and strength equipment exercises and other people use sports nutrition food. Such as: zinc magnesium creatine, crown force heavy chain

Creatine phosphate and ATP are the main energy sources for speed and strength projects, and creatine phosphate combines with phosphoric acid to produce creatine phosphate in the body. Creatine phosphate can quickly decompose and promote the synthesis of adenosine triphosphate (ATP), so that ATP is always in a state of dynamic balance. Supplement creatine can directly improve the energy reserve in the body and improve the explosive power of the body. Therefore, this standard regards creatine, which is very important for strength and speed exercise, as the characteristic nutrient of speed strength project.

E, endurance: with vitamin B1 and vitamin B2 as the characteristic components, suitable for middle-distance running, jogging, fast walking, cycling, swimming, rowing, aerobics, dancing, outdoor sports and other people to use sports nutrition food. Such as: Cambit youth series, track and field teams and other sports team procurement series products.

Endurance sports mainly refer to long-term aerobic exercise, athletes consume a lot of energy, such as the above events require a long period of sustained function to complete the game. The energy consumed in endurance exercise is mainly achieved by the aerobic oxidation of sugar and fat. The main factors that determine the exercise ability of endurance events include: blood glucose level, glycogen reserve, cardiac reserve, blood oxygen-carrying capacity, the level of aerobic metabolic enzyme regulatory factors, hydrated electrolyte balance, etc.

B vitamins (e.g. B1, B2) act as coenzyme factors to regulate and limit energy supply in glycolysis, tricarboxylic acid cycle, oxidative phosphorylation, fatty β-oxidation and amino acid degradation. Endurance exercise poses a very high challenge to the enzymes that regulate aerobic oxidation metabolism and electron transfer chain in mitochondria. When the key nutrients (such as vitamin B group) that affect endurance exercise are not supplemented in time or are insufficient, the activity of the enzymes that regulate aerobic oxidation and electron transfer chain will decrease, and the energy supply rate of aerobic oxidation will decrease, resulting in athletes unable to replenish energy in time. Which in turn affects athletic ability. Supplementation of vitamin B can improve metabolism, improve the activity of aerobic oxidase, and then promote the three energy substances to participate in aerobic oxidation, speed up the body to produce energy.

F, post-exercise recovery: with peptides as the characteristic components, suitable for medium, high intensity or long-term exercise after the recovery of people to use sports nutrition food. Such as: branch chain amino acid peptide, glutamine peptide

After high-intensity, long-term exercise, often due to poor recovery lead to physical decline, and even low immunity and other problems; The use of machinery for high-intensity weight-bearing exercises, muscles are strongly stimulated, if the damaged muscles are not repaired in time, continue to high-intensity training, making the body fatigue accumulation, a long time will produce overtraining, resulting in slow muscle growth, strength decline, muscle pain and stiffness for a long time, and accompanied by mental poor, fatigue and other symptoms. Rational use of sports nutrition food is one of the important means to help sports people speed up physical recovery and fatigue elimination.

The clear classification of sports nutrition food and the implementation of GB24154-2015 "General Principles of National Food Safety Standards for sports Nutrition Food" are of great significance for regulating the domestic sports nutrition food industry and market. The standard and strict audit of sports nutrition food is a good news for consumers and a good news for the development of market norms. Sports Nutrition Food SC certified products are safe national standard level, that is, the high level of food standards.
