It's the exercise that will help you age better

A group of researchers found that aerobic and endurance exercises such as running, swimming, skiing or cycling would help you age better than anaerobic exercises, such as workout. of strength with weights.

The study was published in the European Heart Journal and examines the aging of cells in the human body

Anti-Aging Exercises and Telomeres

Our DNA is Organized in chromosomes. in all the cells of our body. At the end of each chromosome, a repeated DNA sequence, called telomer covers the chromosome and prevents its deterioration. As we get older, telomeres get shorter and it is an important molecular mechanism for cellular aging, which eventually leads to cell death when the telomere is no longer able to protect chromosomal DNA . The process of shortening telomeres is regulated by several proteins. Among them is the telomerase enzyme, which can thwart the process of shortening and even add length to the telomeres.

Researchers led by Ulrich Laufs of the University of Leipzig, Germany, were enrolled. 266 young volunteers, healthy but previously inactive, randomly badigned them six months of resistance training (continuous running), high intensity interval training (warm-up followed by four courses of different intensities), training in endurance (circuit training) in eight machines, including seated rowing, flexion and leg extension, sitting chest pressure and elongated leg) and an unchanged lifestyle (control group) .

The participants randomly badigned to all three types of exercises performed three sessions. s 45 minutes a week and a total of 124 people completed the study . Researchers badyzed telomere length and telomerase activity in white blood cells extracted from volunteers at the start of the study.

Volunteers who performed resistance and high intensity training increased the activity of telomerase and telomere length, which are important for cellular aging and regenerative capacity, which implies aging in good health. Interestingly, resistance training did not exert these effects .
