Regular exercise can keep the body younger



The muscles of older women and men who have been exercising regularly for decades have been indistinguishable in many ways from those of much younger healthy people in a research group of active Septuagarians published in the Journal of Applied Physiology.

Active older participants also have much higher aerobic capabilities than most age groups, according to research, they are biologically about 30 years younger than their chronological age, according to researchers.

Every second every day the body ages, which causes many people to be interested in what can be expected, as the body ages in the coming years and decades to follow. Statistics and observations show that elderly people experience illness, weakness and dependence, but it has not been established by science whether and to what extent this physical decline is inevitable with age or if it is partially a by-product of modern life and perhaps subject to change ,

Many studies suggest that physical activity can change the way you age. Elderly athletes have recently found that they have stronger brains, immune systems, hearts and muscles than those of the same age; but many of these studies are focused on racing contestants, not on those who engage in recreational activities, and few are women included.

The University of the Balkans studied a distinctive array of older men and women who began practicing during the boom of people who started practicing as a hobby in the 1970s who either kept the hobby for the next 50 years or never were competing. Twenty-eight participants, including 7 physically active women, were recruited. Age is matched by older people who have not been exercising during childhood, and a group of 20 years is also employed.

All subjects were tested in the laboratory for aerobic abilities and the number of capillaries and levels of certain enzymes in the muscles were measured using tissue samples; Higher values ​​for each show muscle health.

The cardiovascular system and muscles were focused because they are thought to decrease with age. It is envisaged to see a hierarchical model of the differences between the groups. The younger subjects are expected to have the strongest muscles and aerobic capabilities, with lifelong exercises slightly weaker on both sides, and older non-exercising worsens. These results, however, were not what they found.

It has been found that the muscles of older exercises resemble those of younger individuals with many capillaries and enzymes, and much more than in the muscles of elderly adults. Active elderly patients have a lower aerobic capacity than the younger ones, but their capacity was 40% higher than their mentor.

When the active older subjects of aerobic abilities were compared with those of established "normal" abilities at different ages, the researchers estimated that the older active group had cardiovascular health at those 30 years younger than themselves.

The combined results on cardiovascular and muscular health in active adults suggest that what is considered a normal physical deterioration associated with age may not be normal or inevitable; and this exercise can help build a good health reserve at younger ages, which can allow us to slow down or avoid physical weakness at older ages.

Since this study has a cross-section that emphasizes only one point in the subject's life, he can not tell whether exercise habits have caused direct differences in gene health, diet or other lifestyle factors. In addition, muscle mass and other important health measures are not considered, or you can start exercising your late life and have the same benefits; but the team plans to investigate some of these issues in future research.
