The only effective way to prevent senile infirmity is exercise that increases endurance. This is reported by physiologist Graham Holloway from the University of Guelph in Ontario (Canada).

Researchers have figured out the mechanism of muscle aging by analyzing cellular metabolism in men aged 20 and 70 years. It turned out that as cells age, sensitivity to adenosine diphosphate (ADP), the molecule from which ATP is formed during respiration, decreases by a factor of 10..

When ADP was added to tissue cultures taken from elderly subjects during a biopsy, an increase in the concentration of reactive oxygen species (ROS), including cell-damaging radicals, was observed..

According to scientists, ROS were the cause of age-related atrophy. At the same time, intensive physical exercises, for example, leg presses and loads on the upper body, did not reduce the content of active oxygen in the cells and after 12 weeks.

According to Holloway, the results of the study do not mean that physical activity in general is not useful for combating sarcopenia.. The researcher recommends making time for aerobic exercise, including cycling and swimming..
