learn about metabolism & metabolism system

To answer the question of why the metabolic rate drops as we get older, we must have a clear idea of what is meant by "metabolic rate. Only then can we understand why he relaxes with age. Metabolic rate is the number of calories (a measure of energy) that our body uses burns or simply to stay alive and perform simple functions of the organization.

Interestingly, even when at rest, the metabolic rate is still at work. Thinkers traditional relate slowing metabolic rate as a legacy of the loss of muscle, which is a normal part of aging. The truth of the matter, however, is different. Loss of muscle mass due to aging is not the only factor that influences the metabolic rate of the organism.

Recent research has shown that the metabolic rate can slow regardless of the fact that there is some muscle loss. Thus, a young man who is physical activity may have a higher metabolic rate if it has the same muscle as a senior.

There may be two reasons for metabolism slows down as we age. First, there is a direct link between the amount of exercise and your metabolic rate. In fact, the more you make physical exercise, the higher your metabolic rate. As we age, we tend to spend less time in physical exercises, which could be attributed to the decline in the resulting metabolic rate.

Second, the metabolic rate is directly proportional to the amount of calories that you take a day. That means more calories than you have in the diet throughout the day, the higher your metabolic rate. A reduction in the metabolic rate in the elderly, although they are physically active, could be because they eat less than younger people.

This fact was highlighted by a team of researchers at the University of Colorado who compared the metabolic rate of some physically active and inactive men the same age.

Regarding the relationship of muscle mass and metabolic rate, it was found that older people, they are physically active or inactive, metabolic rate was lower than younger . While older men burned about 64 to 68 calories per hour, young men burned anywhere between 72 to 77 calories per hour.

Interestingly, when young men and older men doing the same amount of exercise, or eating the same amount of calories, the basal metabolic rate remain unchanged.

similar research has also been done to women. It was found that when pre - and postmenopausal women were compared, after adjusting for age-related muscle loss, metabolic rate was below approx. 10% in the post group who are physically inactive. However, there was no difference in the metabolic rate between preoperative and postoperative women who are physically active.

In conclusion, we can say that the slowing or abandoning the metabolic rate is not an inevitable consequence of aging. It has everything to do with your diet and lifestyle you lead. You can check the decline in the metabolic rate by taking the good and nutritious diet combined with adequate physical exercise.

Metabolism consists of a series of complex biochemical process by which the food we eat is converted into energy. Energy is what the body needs to function properly. Rhythm metabolic or BMR is the number of calories that our bodies need to keep the body, even when it is at rest.

It is simply the number of calories your body burns at rest to maintain normal functions of the body such as breathing, blood circulation, etc. The amount of energy released while we are at rest deals with the functioning of vital organs such as the heart, lungs, brain and the rest of our nervous system.

Beyond food processing in energy metabolism is another vital function, it breaks all harmful substances which have been part of our diet, such as drugs, the alcohol, etc. Several hormones that are produced by the endocrine system control the speed at which the metabolic processes take place.

Thyroxine is such a hormone released by the thyroid gland, which plays a crucial role in determining the speed or slow the rate of metabolism would be. There are many disorders that occur in the body that has a direct relationship with co-metabolism. The main cause of all these disorders, also known as the metabolic syndrome is insulin resistance unrest.

Sedentary lifestyle and genetic factors may lead to the metabolic syndrome, which greatly improves the chances of developing a whole series of heart-related including heart attack, stroke, etc. < br>
There are a number of risk factors, as defined by the World Health Organization (WHO), which form the basis of diagnosis of metabolic syndrome. These include: •

abdominal / Central Obesity - Waist: greater than 40 inches men, and more than 35 inches for women or BMI (body mass index) greater than 30 kg per m2

• Elevated Triglycerides-greater than 150 mg / dL (1.7 mmol per L)

• Low HDL cholesterol less than 35 mg / dL (0.9 mmol / L) for men and less than 39 mg of / dL (1.0 mmol / L) for women

• High Blood Pressure-greater than 130/85 mmHg

• Fasting Blood Sugar greater than 110 mg d '/ dL (6.1 mmol / L)

• Type 2 Diabetes and Impaired Glucose Tolerance

• Urinary - Secretion albumin greater than 110 mg d '/ dL (6.1 mmol / L)

• Inflammatory state-Elevated C-reactive protein in the blood

With the obesity and diabetes on the rise, it is estimated that not only children and adolescents are affected, but also a large proportion of the population between 60 and 70 years. Obese people who lead a sedentary lifestyle, and who are smokers are not just victims of high cholesterol levels, but a malfunctioning metabolic rate as well.

You discover that cholesterol and metabolic are very closely related, if you look at the causes of metabolic syndrome. Obesity, caused by physical inactivity combined with a diet containing lots of carbohydrates and trans fatty acids, have been identified as the cause of high cholesterol, and metabolic disorders.

It is believed that if you have three risk factors that are known to be part of the metabolic syndrome, as mentioned above, then the more likely that you have heart disease (including heart attack, cerebrovascular disease or diabetes).
