How to live longer: Endurance exercise helps to offset the damaging effects of ageing

Research into the importance of regular exercise is conclusive but knowing what to do and how long to do it is still fiercely debated. While studies have linked short bursts of exercise to a longer life, it is hard to ignore the evidence supporting endurance activity.

Remarkably, in the follow-up study 30 years later, an endurance training program using a relatively modest intensity of training was able to reverse 100 percent of the loss of cardiovascular capacity, returning the group to their 1966 baseline levels of aerobic power.

The five study volunteers completed a six-month, individualised endurance training program.

Two study participants took part in walking exercises, two jogged and the fifth trained on a stationary bicycle. The endurance training was increased weekly.

“By the end of the study, the subjects were exercising weekly about four and a half hours divided into four to five exercise sessions,” said Dr Darren McGuire, assistant professor of internal medicine and lead author of the study.

The health benefits of endurance exercise

As the Texas studies showed, endurance exercise is the best way to improve cardiovascular function.

“It helps keep the heart muscle supple and the arteries flexible, lowers the resting heart rate, and boosts the heart’s peak ability to deliver oxygen-rich blood to the body’s tissues,” explains Harvard Health.

What’s more, endurance exercise is also the best way to protect the body’s metabolism from the effects of age.

As Harvard Health points out, it reduces body fat, sensitises the body’s tissues to insulin, and lowers blood sugar levels.

“Exercise boosts the HDL (“good”) cholesterol and lowers levels of LDL (“bad”) cholesterol and triglycerides,” it adds.

Cholesterol and triglycerides are fatty substances that can clog up your arteries, thereby raising your risk of cardiovascular problems.

Aerobic exercises – continuous activity that works your heart, lungs and muscles – form the basis of endurance workouts.

Examples include brisk walking, cycling and running.
