Everyone’s body has a slightly different reaction to cold and some people feel cold more often than others. This is called cold intolerance. Women are more likely than men to feel cold all the time. One reason for this is because women have a lower resting metabolic rate.
Feeling refreshed by taking a dip in icy water after exercising may be a priority for some professional athletes who can relieve their fatigue. But if one does it in the winter to keep oneself healthy, then the cold can be as severe as it is fun to do.
Bathing in hot or cold water is not an option for swimmers. Bathing in cold water is good for their health but not for everyone.
“When I tried to swim openly, I couldn’t stay in the water for long. I could only stay in the water for a few minutes and then come out,” he said. There are some reasons why my sister can stay in the water longer. I think there is a difference between us when it comes to enduring the cold. “
The media has mentioned some mental health benefits of bathing in cold water, but they are not very clear. These benefits are largely based on the experiences of a 24-year-old woman. However, it is not known why this case study is so popular.
Is Matilda right in saying that some people fight the cold differently than others?
The weather also affects our performance. In the cold our limbs become sluggish, stress takes longer, and it affects our ability in two ways: Has an effect. However, to reduce these effects, we can warm ourselves up before taking a water.
The reasons for poor performance in cold weather are more complex, our endurance in cold weather depends on our genetics, subcutaneous fat and body size.
One idea is that when our body cools down, the rate of energy release in our body cells decreases, which affects performance.
Exercising in the cold is said to be good for heart health, it can ensure a strong immune system and it turns white blood cells into brown blood cells, which leads to weight loss.
So if you do it safely, it can have many health benefits.
Some of us may benefit from exercising in the cold. One in five people is deficient in muscle fiber protein A. actinin-3.
This change sheds some light on our evolutionary history of how some modern athletes are able to perform better in cold weather while others become weaker in the beginning.
The muscle protein ‘A-actinin-3‘, a muscle-building gene, is relatively beneficial to athletes when they are expending their physical energy to strengthen their muscles. But it may not be very useful in other situations.
Our muscles are a mixture of two types of fibers, slow and fast fibers.
Courtney Dunn-Lewis, a psychologist at the University of Pittsburgh, says that although both types of muscle fibers are present, the rate of each of them may be different, depending on the different muscles and in different humans. Rates may vary.
Slow-moving fibers slow down aerobic action.
These fibers keep us upright. They keep our heads from falling and our jaws from opening and they help us walk and run.
If you have ever tried yoga or meditation and you have been instructed to relax all the parts of your body, then you will realize how many muscles in the background become unconsciously active. Are
This is not a muscle strain. This is a normal part of the body called the tonsils, under which the slow-moving muscles prevent us from swinging.
Fast-moving fibers, on the other hand, can move anaerobically (without oxygen) immediately during respiration, but can easily cause fatigue.
These fibers move only when we are lifting something heavy, jumping, running fast and any kind of exercise that requires anaerobic exercise.
A. Actinon-3 protein genes are found only in muscle-moving fibers.
According to Dun Lewis, 80% of athletes have muscle fibers that move either fast or slow, meaning that high-strength athletes have high-moving fibers in their limbs, while long-term athletes tend to be slow-moving.
Consider the long, slender body of a marathon runner, whose muscles may have slow-moving fibers, but they prevent fatigue and give them the strength to run for many kilometers. ۔
Such a person consumes less physical energy in the allotted time. In contrast, the muscles of an American footballer or hockey player have fast-moving fibers, which move with force and speed but quickly lead to fatigue.
Athletes who have up to 80% of the same type of fiber in their muscles are lucky. In normal humans, the ratio of these two types is fifty-fifty. This ratio is determined at birth.
The type of fiber is determined by the nervous system, so it cannot be changed by exercise.
You can also tell the difference between these two types of fibers by considering chicken. The flesh on the chicken’s leg is black because it contains slow-moving fibers and contains myoglobin, a protein attached to oxygen, which enables aerobic transmission to the muscles through inhalation. ۔
Because myoglobin is high in iron, which is somewhat like blood, it makes muscles black and red.
In fact, when you divide it, the red substance that comes out of it is not blood but myoglobin, which gets this color from the corresponding hemoglobin.
Chicken breast meat is light in color because it is dense and has fast moving fibers. Meat is not very dense in myoglobin. Chicken chest muscles are needed for short, fast, anaerobic type activities when birds flutter their wings. While their legs are being used more frequently.
This difference is less obvious in humans. Our muscles are more or less a mixture of both types of fibers.
These fibers play a very important role in keeping us warm. When it’s cold, our fast-moving fibers are doing their job over and over again. Which is why we are shrinking ourselves further to avoid the cold.
When we are somewhat warm, then our energy is wasted. Spending this energy is a way to keep the body warm but it is effective immediately.
“One of the most effective ways to raise your body temperature is to tighten your muscles,” says Dunn Lewis. In fact, 70 to 80 percent of the calories you burn from exercise are because of the heat.
Our lazy fibers work in the style of tones, which generate a lot of heat.
The protein A-actin-3 gene is not present in 1.5 billion people worldwide. But they still have fast-moving fibers. Their muscles are less flexible and they are thicker than slow moving fibers. Which means it’s about to be the most delusional time of the year, as well as the most delusional.
According to the author of the research paper, such people are sure to succeed in sports that are long-lasting. They may be less capable of doing anaerobic activities, but they can use energy more efficiently.
As a result of mutations in A. actinin-3 genetics, human ancestors who migrated from Africa to Europe 50,000 years ago are losing their protein genes.
This genetic mutation may have helped the ancestors of Europeans cope with the cold weather. Because compressing the body reduced their energy consumption instead of relying on tones.
According to Dun Lewis, such genotypes are less common in ethnic groups living in warmer climates. It is found in only 1% of Kenyans and Nigerians, 11% in Ethiopians, 18% in whites (Europe, Central Asia) and 25% in Asians.
According to the model outside Africa, polymorphism has increased among those who migrated to cold regions. People who are deficient in A. actin 3 can better stay warm and have enough energy to withstand severe weather conditions.
Determining our genetics also includes how we cope with the cold: the amount of fat in our bodies. Just as we have two types of fibrous organs, so we have two types of fat in our body. White and brown fat One of which helps to warm the body.
Brown fat is thermogenic, which means that our lazy fibers now warm us up before we shiver.
Kirsten Stanford, a cell biologist and her co-authors at Ohio State University, have published a study on the role of gray matter in keeping our body temperature normal.
Gray fat is thermogenic, which means our lazy fibers warm us up before we shiver. As soon as we catch a cold, our brown fat starts moving, which makes us lose weight. According to Kirsten Stanford, the same method can be used to treat obesity.
However, exercise has the opposite effect on our brown fat. Exercise seems to stop this activity. Probably because when we exercise we are generating a lot of heat through other mechanisms. However, the authors emphasize that no final results of the research have yet emerged.
“Although cold weather prevents the burning of brown fat and slows down the nerve impulses in our organs, which can affect our performance in sports,” says Dunn Lewis. In practice, if a person’s body temperature is right … their body warms itself easily.
There is no reason not to exercise in the cold.
According to him, in fact, the best time for a marathon is in cold weather because cold helps to eliminate the heat generated during exercise. If it weren’t for the cold weather, the human body would have used other means to get rid of the heat, rather than muscle function.
Not all big players perform well in the cold. Cold weather exacerbates exercise-induced asthma, affecting 35% of winter Olympic athletes. Cold air is less humid because moisture accumulates in the air.
Dry air is thought to cause an inflammatory reaction in the lungs.
So there are genetic reasons why some of us find it more difficult than others. One of the benefits of the change in A. Actin 3 is that people get up in the morning to swim in the open water while the rest of them try to get out of the house and run.
A crowded public pool near his house will suffice for the time being.
