Is there too much oxygen for two hours a day? Many people in life don't know how long it takes to do sports every day. Everyone knows that excessive exercise is bad for your health. Some people want to know whether doing two hours of aerobic exercise every day is too much. The following is an introduction to the content of two-hour aerobic overdose every day, hoping to help everyone!
Is there too much oxygen for two hours a day? 1 It's not too much to exercise for two hours every day. Ordinary people exercise more than 3.5 hours a day to be considered excessive.
The time of exercise every day is determined according to personal circumstances. Generally speaking, aerobic exercise such as brisk walking, jogging, ball games, swimming, cycling, etc. It takes 30 to 60 minutes every day. Of course, young people with good health can appropriately increase the amount of exercise, and middle-aged and elderly people can appropriately reduce the amount of exercise. The demand for exercise is different for each age group.

Precautions for healthy exercise:
Don't eat for 2 hours before exercise. It is best to eat beef or lean pork 3 hours before exercise, but it is not recommended to eat greasy puffed food. Don't drink plenty of water before exercise. It is recommended to sip a small amount of normal saline. Don't wear soft-soled shoes for running, high jump and long jump, and the shoelaces should not be too long.
You should rest as early as possible the night before, check your sports equipment and do something that usually makes you happy. Don't sit on the ground and rest immediately after exercise. You should walk slowly for about 100 meters. Don't drink water immediately because you are thirsty, otherwise it may cause dehydration. It is recommended to drink a small amount of normal saline every 2-3 minutes after the heartbeat is relatively stable.
Can't rest immediately: During strenuous exercise, people's heart rate will accelerate, muscles and capillaries will expand, and blood flow will accelerate. At the same time, the rhythmic contraction of muscles will squeeze the venules, prompting blood to flow back to the heart quickly. At this time, if you stop to rest immediately, the rhythmic contraction of muscles will also stop.
Don't take a bath immediately: after strenuous exercise, in order to keep the body temperature constant, blood vessels on the skin surface dilate, sweat pores expand and sweat increases, which is beneficial to heat dissipation. At this time, if you take a cold bath, the blood vessels will contract immediately, the blood circulation resistance will increase, and the body's resistance will decrease, and people will easily get sick.
Don't binge drink to quench thirst: When thirsty after strenuous exercise, some people binge drink cold boiled water or other drinks, which will increase the burden on gastrointestinal tract and dilute gastric juice. This not only reduces the bactericidal effect of gastric juice, but also hinders the digestion of food. Drinking water too fast will also increase the blood volume too fast and suddenly increase the burden on the heart.
Don't eat a lot of sugar: Some people feel comfortable eating sweets or sugar water after strenuous exercise, and think it is good to eat sweets after exercise. In fact, eating too much sweets after exercise will consume a lot of vitamin B 1 in the body, and people will feel tired and lose appetite, which will affect the recovery of physical strength. Therefore, it is best to eat more foods containing vitamin B 1 after strenuous exercise, such as vegetables, liver, eggs and so on.
You can't eliminate fatigue by drinking: after strenuous exercise, people's physical function will be at a higher level. Drinking alcohol at this time will make the body absorb alcohol faster and enter the blood, which will do more harm to organs such as liver and stomach than usual. This will cause fatty liver, cirrhosis, gastritis, gastric ulcer, dementia and other diseases for a long time.
No smoking to relieve fatigue: Smoking after exercise will accelerate human metabolism, and all organs in the body are in a high-level working state, which will make a lot of smoke enter the body. The body cannot be satisfied because it needs a lot of oxygen after exercise, and it is more vulnerable to carbon monoxide, nicotine and other substances.
Is there too much oxygen for two hours a day? The longer the fitness time, the better the actual effect may not be.
As far as aerobic exercise with low compressive strength is concerned, with the increase of time, the proportion of body fat phosphorus will increase. In other words, the longer you exercise, the more body fat you lose. After 30 minutes of continuous aerobic exercise to lose weight, the triglyceride in blood reaches the highest level, and the proportion of phosphorus in human fat also reaches the highest. Therefore, it is generally recommended that moderate compressive strength aerobic exercise should last at least 30 minutes to lose weight.
The proportion of high-toughness aerobic exercise to lose weight and burn fat is relatively low. People who want to lose weight should do less high-toughness aerobic exercise to lose weight. According to the characteristics of jogging, when jogging lasts for 30 minutes, our bodies just start to burn fat efficiently, and when the fitness time lasts for 65,438+0 hours, our bodies can produce muscle-consuming protein to supply energy. Although it varies from person to person, an hour and a half of aerobic exercise time will definitely cost our protein to reach phosphagen.
The key cost of muscle training is fibrinogen, and the proportion of burning fat phosphofibrinogen is relatively low. But that doesn't mean you can't lose weight through muscle training. In the whole process of fitness exercise, the weight-losing ability of aerobic exercise is obviously better than that of muscle training, but the fat-reducing effect of muscle training lasts for a long time and finally exceeds that of low compressive strength training within 24 hours.
How long does it take to exercise a day?
When you exercise to lose weight, you can do aerobic exercise with moderate compressive strength for a long time. It is recommended to lose weight for 40 minutes to 60 minutes at a time. After muscle training, aerobic exercise can lose weight in a shorter time, up and down for 30 minutes. If you are not fat, fitness exercises only reduce fat and gain muscle. You can do more muscle training for 30 minutes at a time.
