Starting today, let’s start a topic in the future: fitness nutrition related knowledge sharing. I will put this thing in the official account menu and update it slowly in the future. At present, we are known to know that the knowledge in the field of fitness is roughly divided into: exercise training, sports nutrition, sports decomposition , etc. At present, the knowledge we mainly share is in exercise training . exercise decomposition is very complicated, and we don’t understand it, and we can’t talk nonsense, so we won’t mislead you, right? The second is sports nutrition , which combines the professional books in my hand and some authoritative nutrition articles I usually read, and I will share with you the relevant knowledge in this regard.
This article highlights : . Why do fitness people learn nutrition knowledge and . Seven major nutrients
. Why do you need to learn nutrition-related knowledge?
First of all, don’t underestimate this knowledge. Simply think that fitness = . Let me give you a simple example: Everyone knows can grow muscles, but why can whip harden muscles? Let’s roughly say that strength training causes muscle fiber damage to , and the human body needs to repair it, right? But repairing requires materials, right? What materials should I use? You guessed it right, that is protein . So do fitness enthusiasts need protein supplements? If needed, how to supplement protein? When will it be supplemented? How much is appropriate to supplement? Do you need to supplement with other nutrients? For related issues such as training day supplement and non-training day supplement, believes that after learning relevant knowledge, you will have basic judgments and grasp !
Besides, what do we rely on to provide energy in strength training? Why can’t I move after 10 strength training times and I can’t move after 6 times? To put it bluntly: it is related to the human body's ATP energy supply . ATP energy supply is related to carbohydrate and fat , because carbohydrates mainly participate in glycolysis energy supply, and fat only participate in aerobic metabolism energy supply. Our strength training mainly uses anaerobic glycolysis to supply energy. 's metabolism will produce a large amount of lactic acid and hydrogen ions, causing the pH value in the muscle to decrease, and the muscle strength will also drop sharply. This is also the reason why you can't lift 100 times in a large weight! Here I would like to add one thing: Powerlifters mainly use the phosphate energy supply system to supply energy, and this will be said in the future!
. I've talked about the roles that [ protein, carbohydrates, fat ] play in strength training. In fact, is more complex and highly polymerized , because is too complex, not as simple as we imagined, and there are individual differences between different people !
Seven major nutrients
Regarding fitness nutrition, it must be impossible to escape: The seven most important nutrients in the human body. So where do these seven nutrients come from? Of course it is obtained from food. Food provides the human body with seven basic nutrients: water, protein, carbohydrates, fat, vitamins, minerals (inorganic salts), and dietary fiber .We won’t say too much here, let’s give a brief introduction, and we will talk about it in one article in the future, so stay tuned!
Water : Water is the source of life and is the basis of for the human body to intake nutrients !
Protein : important raw material for repairing the body ! It consists of a long list of - amino acids !
Carbohydrate : It can burn quickly to provide energy to organisms , which is closely related to insulin !
fat : an energy substance for long-lasting exercise, which is inseparable from aerobic metabolism of !
Vitamin : Human metabolism plays an important role!
Mineral : Also known as inorganic salt, the human body cannot synthesize and is divided into constant elements and trace elements!
Dietary fiber : polysaccharides carbohydrates that cannot be digested and absorbed by the human body in the plants!
. The above is the understanding of nutrition in and the sharing of the seven major nutrients !
Every sharing is a step forward for you! Come on, everyone!
This article was first published on the WeChat public account [ Fitness guy Dongzhe ]!
So that’s all for today’s sharing, see you next time!
