Endurance but not resistance training has anti-aging effects – Study

Researchers have discovered evidence that endurance exercise, such as running, swimming, cross-country skiing and cycling, will help you age better than resistance exercise, which involves strength training with weights, as reported in Medical Xpress.

In a study published in the European Heart Journal, researchers in Germany looked at the effects of three types of exercise—endurance training, high intensity interval training and resistance training—on the way cells in the human body age, and they found that endurance and high intensity training both slowed or even reversed cellular aging, but that resistance training did not.

Our DNA is organized into chromosomes in all the cells in our bodies. At the end of each chromosome is a repetitive DNA sequence, called a telomere, that caps the chromosome and protects its ends from deteriorating. As we grow older, the telomeres shorten and this is an important molecular mechanism for cell aging, which eventually leads to cell death when the telomere are no longer able to protect the chromosomal DNA. The process of telomere shortening is regulated by several proteins. Among them is the enzyme telomerase that is able to counteract the shortening process and can even add length to the telomeres.

Women need strength training to ward off aging effects – Study

The more I work on this blog the more I get the idea that whatever the problem exercise is the answer. Eat less; move more; live longer.

Regular physical activity may help older women increase their mobility, but muscle strength and endurance are likely to succumb to the effects of frailty if they haven’t also been doing resistance training.

That is according to the findings of a cross-sectional study led by the University at Buffalo and published in the journal Physical & Occupational Therapy in Geriatrics.

The study underscores the need for older women to build up muscle strength early in the aging process to help ward off the effects of aging, say the study’s lead authors Machiko Tomita, clinical professor, and Nadine Fisher, clinical associate professor, both in the Department of Rehabilitation Science in UB’s School of Public Health and Health Professions.

“Frailty progresses with aging, but older women who engage in a high level of daily physical activity can reverse certain characteristics related to aging, such as slow walking and decreased function,” says Tomita. Continue reading
