Scientists have learned, what sports prolong life
Any aerobic activities have a better effect on health than all other types of exercises. To such conclusion scientists, who published an article in the European Heart journal.
In recent years, scientists have been actively interested in how different kinds of exercise not only affect muscle condition and metabolism, but also on life expectancy and its quality in old age.
For example, a few years ago, scientists from Belgium have found that many forms of charging to slow down aging and rejuvenate human cells, causing them to produce proteins responsible for repairing the so-called the telomeres — the end parts of chromosomes. Later, their Australian colleagues analyzed what kinds of activities have the best effect on human health, increased life expectancy of older people in Britain. For example, such properties have tennis, aerobics and Cycling, and soccer and running almost no effect on longevity.
“All the doctors recommend exercise, however, no one has conducted large-scale inspections of how it affects real longevity in humans,” said Ulrich Laufs from Leipzig University.
Analyzing the results of previous experiments, he and his colleagues noticed a curious pattern — all types of exercise were most beneficial to the body, were among the so-called endurance, strengthen the heart and help muscles more efficiently use oxygen.
They gathered a group of nearly three hundred volunteers who agreed to drastically change your lifestyle. Scientists “wrote” them with different sets of exercises, and within six months, watched how varied their telomeres.
Some of the volunteers were just doing mild forms of aerobics, others alternated episodes of heavy and light load, pedaling on a bike or paddle boat. The third group worked on simulators designed to enhance maximum strength.
However, only half of the volunteers threw these classes and comply with the regime until the end of experiments. They helped scientists to prove that changes in the telomere length really depended on the type of load.
For example, it was found that the activity of proteins that protect them from destruction, grew by about two to three times the volunteers, engaged in Jogging, aerobics, rowing and spinning classes, but has not changed among fans of weightlifting. This means that the cells of athletes involved in athletics or aerobics, age more slowly than the body lovers “rocking” bar.
Successful completion of these experiments, as I hope, Laufs and his colleagues, will attract the attention of other scientists to this problem that will allow us to conduct more extensive re-checking their findings.
