Brief bursts of high intensity exercise can be particularly beneficial for improved cardiovascular health, new research suggests.
A study published online in the journal American Journal of Physiology showed that short high-intensity forms of exercise, such as sprints, can improve the function and structure of arteries more than longer, moderate exercise.
The study found that completing 30-second sprints three days each week for six weeks improved cardiovascular health as much as 40 and 60 minutes of cycling five days a week.
Commenting on the latest findings, Maureen MacDonald, an associate professor in the Department of Kinesiology at McMaster University, Canada, explained: "As we age, the arteries become stiffer and tend to lose their ability to dilate, and these effects contribute to high blood pressure and cardiovascular disease. More detrimental is the effect that blood vessel stiffening has on the heart, which has to circulate blood."
"More and more, professional organisations are recommending interval training during rehabilitation from diseases," she added.
