New research has found that on top of all of the other health benefits you already know about exercise, it can help with aging, too.
According to this study, you should add endurance and high-intensity interval training (HIIT) to your routine. These exercises keep your heart rate up and can keep your cells younger for longer. The researchers determined this by measuring the structures at the end of chromosomes, known as telomeres. Thanks to older research, we know that our telomeres start to shrink as we age. Also, older people with longer telomeres don’t experience vascular aging as rapidly as people with shorter ones. This means their veins are generally in better shape and they’re less at risk for conditions like heart disease and stroke.
Details of the study
The researchers also found that the people in the aerobic and HIIT groups experienced more telomerase activity. This is the process that caused their chromosomes to become longer.
It’s worth noting several things about this study:
It also wouldn’t be accurate to say that it’s aerobic or HIIT exercise alone that cause this change in healthy aging factors. These exercises help play a part in stimulating nitrous oxide, which helps keep your mitochondria healthy and maintain the fight-or-flight mechanisms in your body.
While the study didn’t find anti-aging benefits from resistance training, it doesn’t mean there’s no benefit to weightlifting. As you get older, your body will have decreased muscle mass. This can increase your risk for:
If anything, treat this study as a reminder to maintain a balanced approach to exercise. Try a mix of aerobic and resistance: Run on Tuesdays and lift weights on Thursdays.
Start your telomere-friendly routine anytime
If you’ve never been a gym aficionado, aerobic and HIIT workouts are a great way to start. After all, the study saw growth in the telomere length of middle-aged participants even with no fitness background. Tip: Almost any workout can become HIIT workouts simply by creating intervals of intensity.

The ECU study was a collaboration with researchers from the Herlev & Gentofte University Hospital, Aarhus University, as well as the Danish Cancer Society Research Centre, Aalborg University Hospital, the Universities of Western Australia and the International Agency for Research on Cancer.
