Scientists at the University of Leipzig (Germany) found out that endurance exercise, like running, swimming, skiing and Cycling, provide more effective anti-aging effect than weight training. About it reported in a press release on EurekAlert!.
The study involved 266 young people who were not previously engaged in physical activity. Experts randomly assigned subjects into groups. In one group of people for six months was engaged in exercise on endurance (long run), the other high-intensity interval training (warm-up, alternating fast and slow running and finishing a slow run), and one with strength training. The last group served as a control, that is, the people in it do not change the way of life.
The classes were held for 45 minutes three times a week, and only 124 people stayed until the end of the study. The researchers analyzed the telomere length of the participants and telomerase activity in white blood cells, which the volunteers took at the beginning of the experiment and 2-7 days after its completion.
It turned out that all of the subjects, doing endurance exercise, increased lengths of telomeres that protect the DNA from damage during replication of chromosomes, and increased the activity of telomerase that restores the telomeres. Strength training had no effect. According to scientists, the physical activity affects the level of nitric oxide in the blood vessels, which in turn improves the functioning of cells.
