The effect of the clothes on the back of the body is very different - some people can pull a deep ditch on the back of the armpit, some people are not thick but have a swim ring, some people are under the short sleeve Exposed the swaying "bat arm". Pinch the arms and feel soft as cotton; walk, thighs and thighs together.
These conditions all indicate that the muscles are soft and atrophy, and the body fat content is too high, so be careful.
Muscle tightness is associated with diabetes and heart disease
Today, no matter what age, there are fewer and fewer people with tight muscles. Men don't have time to exercise, spend more time on the wine table, and even don't care about the increasingly prominent abdomen; women are even more reluctant to exercise, saying that they are afraid of muscle affecting women's femininity. Only after the weight exceeds the obesity standard, someone warns them that obesity can lead to diabetes and coronary heart disease.
Why do you eat the same thing, some people will be fat, some people will not?
Does muscle tension have anything to do with diabetes and heart disease? What is the most fundamental measure to prevent these chronic diseases? A study by the National Academy of Sciences reveals the striking fact that insulin resistance in skeletal muscle is the underlying cause of obesity, metabolic syndrome, and diabetes.
The researchers divided young subjects with normal weight into two groups: one group had normal insulin sensitivity and the other group had insulin resistance, but did not develop any chronic disease. The so-called insulin resistance, is that because the body postprandial secretion of insulin hypoglycemic inefficient, under the same circumstances insulin secretion, postprandial blood sugar can not fall quickly, more insulin must be mobilized to complete the task.
"Drinking cold water and long meat" has scientific evidence
Both groups received exactly the same food, but the researchers found that their physiological responses were quite different.
Compared with people with normal insulin response, insulin resistance has a 60% reduction in the amount of muscle glycogen ( used in muscle for exercise ) , while in their liver, fat synthesis reaches another group. More than twice! At the same time, their plasma triglycerides are 60% higher , while high-density lipoprotein cholesterol (HDL) is 20% lower . This is really the scientific evidence of the so-called "drinking cold water and long meat."
The researchers concluded that eating the same thing, for insulin-sensitive people and insulin-resistant people, the metabolic effects are very different. The former uses most of the carbohydrates to turn the energy needed for muscle activity, while the latter
They are used to synthesize fat, which leads to an increase in triglycerides, an adverse change in blood lipids, and even hardening. Because this early change occurred before abdominal obesity and generalized obesity, the researchers believe that this change in skeletal muscle may be a very early stage of metabolic syndrome, obesity, diabetes, and coronary heart disease.
Less physical activity, soft muscles, no overweight, and prone to chronic illness
So, how can we prevent the problem that "skeletal muscle is not sensitive to insulin"? How can we strengthen the manufacturing function of muscle glycogen? The researchers gave an extremely succinct answer: enough physical activity.
Professionals point out that because there is not enough physical activity, over time, skeletal muscle will "use and retreat", it is no longer good at efficient work, can not be a large amount of glucose into the blood, leading to insulin insensitivity; This problem in turn leads to increased fat synthesis and increased blood lipids. Even if a person is still very young and has not even entered the middle age stage, due to long-term lack of exercise, muscle weakness and decreased strength, it will lead to obstacles in blood sugar metabolism, and high blood sugar after meals will gradually lead to an increase in the proportion of physical fat. Lead to the occurrence of chronic diseases.
Studies have found that if a woman's muscle strength is poor, her risk of developing diabetes in the future will increase greatly. Conversely, if people with diabetes are actively active and gain muscle strength, their blood sugar control will be significantly improved.
Experts suggest that for people with little physical activity and weak muscles, even if the weight is not exceeded, the risk of diabetes and heart disease will rise. Early physical exercise, so that the muscles are always in a healthy and powerful state, regardless of men and women, not only is the key to maintaining a beautiful body shape, but also one of the most fundamental measures to prevent obesity and a variety of chronic diseases.
