The fact that prolonged breaks in training are equal to the loss of the previous physical form, everyone is well known. But not everyone imagines what processes occur in the body, if you give up fitness for a long time. Scientists understood the question.
The latest research is another proof that active rest is always better than idleness, and even without movement. Scientists at the University of Liverpool last year conducted an experiment involving 45 men and women who, in terms of metabolic processes, were healthy and passed at least 10,000 steps a day, that is, they were quite active. As it turned out, if they reduce their mobility by 95% (for example, reduce the number of steps to the mark <2000, and add «sedentary» hours of about 3.5) for at least two weeks, this will turn into «metabolic disorders», as reported in the scientific journal Diabetologia. Worsening of the cholesterol profile, increased blood sugar and decreased insulin sensitivity, loss of muscle mass and the appearance of more voluminous adipose tissue were what the study participants expected after a crescent without training.
Fortunately, most subjects managed to return to normal as soon as they started training again; however, not all. Some of them, even after two weeks, had symptoms of insulin resistance.
More noteworthy is the study of The Journals of Gerontology, published a little earlier than the previous one. It was carried out with 65-year-olds with problems with overweight; hyperglycemia is the reason that they were close to the development of Type 2 diabetes. And this despite the fact that their activity remained at a good level — this is 7000-8000 steps per day.
It cost them to reduce this number to 1,000 steps (or even less), as blood sugar control deteriorated significantly. Changes in muscle tissue were observed, which resulted in weight loss. Some, by the way, even had to be removed from the experiment in order not to expose them to the risk of diabetes. What was surprising was not so much these consequences as the fact that there was no resumption of rehabilitation activity after two weeks. People in the age category taken by scientists were not so easy to reverse the metabolic changes that had occurred to them.
Thus, in adulthood, lack of activity is equivalent to a high probability that health problems will begin. The older a person, the more difficult it is for him to overcome the consequences of training interruptions. So it’s better to stay steady in motion — if you do not train, then at least walk, arranging yourself a walking cardio.
