As we all know, food can be divided into two categories: alkaline food and acidic food. People must mix acidic and alkaline foods to maintain the balance of blood PH in the body. The so-called acidic and alkaline foods are not identified by taste or taste, but mainly by the chemical elements contained in the food being absorbed and oxidized by the human body. Generally, acidic foods contain more nonmetallic elements such as nitrogen, sulfur and phosphorus, while alkaline foods contain more metallic elements such as sodium, potassium, calcium and magnesium. Either the taste is sour or acidic foods, such as vinegar, oranges, plums, apricots and other fruits are also acidic, but they are not acidic foods, but typical alkaline foods. Another example is animal meat such as cereals, sweets, cakes, fish and pork, which are not alkaline foods but acidic foods.
Under normal circumstances, the pH of human blood is balanced, and slightly alkaline is preferred. After strenuous physical labor and strenuous physical exercise, the sugar, fat and protein in the body will be decomposed in large quantities, resulting in more acid, which will make people feel sore in the waist, legs or whole body muscles and make people feel tired. In this case, if you drink Coca-Cola and the sugar content of Coca-Cola is high, it is acidic food, and eating chocolate candy and the like is also acidic food. After eating these things, it is bound to "add fuel to the fire", which will definitely increase the acidity in the blood, thus aggravating the pain of human muscles and making it more difficult to eliminate fatigue in time.
So, what should I eat after work or exercise? You should eat alkaline food. Among animal foods, only milk and animal blood are alkaline foods, and others are acidic foods. For drinks, it is best to drink milk, soybean milk, tea, fruit juice (without sugar), mineral water or boiled water.
As for drinking salt water or sugar water after exercise, we should grasp it flexibly according to the specific situation.
Generally speaking, in the case of sweating more, especially when engaged in strenuous exercise in summer, you should drink some light salt water appropriately. In summer, when the temperature is high and the humidity is high, the human body will emit a lot of heat energy in time through perspiration to keep the body temperature relatively stable. When the body sweats a lot, it will take away a lot of inorganic salts, such as sodium, potassium and magnesium. According to measurement, running a marathon takes away 30 grams of sodium chloride with sweat. However, a person's daily intake of sodium chloride from food is only 10 ~ 15g, which will inevitably lead to salt deficiency in the body, fatigue and weakness, and even muscle spasms or cramps. Therefore, it is necessary to drink some light salt water when engaging in strenuous exercise in summer.
Exercise under the conditions of not too much intensity, not too long time and not too high ambient temperature will generate less heat in the body and will not produce a lot of perspiration and inorganic salt loss. Neither salt water nor sugar water is needed at this time.
If it is a long-term exercise, such as running a marathon, long-distance running by bike, etc. And your body consumes a lot of energy, so you should drink some sugar water or sugar salt water properly. As for general physical exercise, there is no need to drink sugar water.
As for food, tofu, dried tofu and all kinds of bean products, as well as fresh fruits, melons and fruits and all kinds of vegetables are most suitable for eating after work and exercise. These are all good alkaline foods. Kelp is called "the crown of alkaline food". In addition, stir-fry sesame seeds and soybeans, add ginger and a little salt, and brew with boiling water to quench your thirst. Sesame, soybean and ginger are all good alkaline foods, which are also conducive to reducing the acidity in the blood and eliminating post-meal fatigue.
The effect of fitness running is fast and remarkable.
Fitness running is known as "the king of aerobic metabolism" and is a typical aerobic exercise mode. Because of its rapid and remarkable fitness effect, low technical requirements for running and no need for special sports venues and equipment, it has become popular all over the world in recent years, and more and more people have joined this fitness plan.
Give you a reason to run and exercise.
Long-term running will gradually develop and strengthen the heart muscles, bradycardia, thickening of blood vessels, increased capillaries, enhanced respiratory function and increased vital capacity. Fitness running is also one of the most effective ways to lose weight. Long-term aerobic exercise can fully burn off excess fat. The rhythmic contraction and relaxation of muscles during running can coordinate the process of excitation and inhibition of cerebral cortex and help to enhance the function of nervous system. Fitness running can also promote gastrointestinal peristalsis, increase the secretion of digestive juice, promote appetite and strengthen the function of digestive system.
Are you suitable for fitness and running?
Fitness running is suitable for people of all ages, especially obese people and people with high risk of obesity, as well as people with poor cardiopulmonary function and muscle endurance. However, patients with cerebrovascular disease, habitual headache and visceral ptosis are not suitable for long-distance fitness running. In addition, the elderly and children should shorten the running distance appropriately, or adopt the exercise mode of alternating walking and running.
Before and after the fitness run, you must be prepared and finish the activities. When running, the whole body is relaxed, the forefoot touches the ground, the body leans forward slightly, the arms swing naturally, and you walk quickly, take a deep breath, long and thin, slowly and rhythmically. You can breathe in two steps, two steps, or three steps. Exhale as rhythmically as possible. When inhaling, the abdomen bulges and naturally forms abdominal breathing. The amount of exercise varies from person to person, so it is advisable to run into the sweating program as much as possible, so that the body feels a little tired after exercise and does not affect normal work and study.
