A new research published in the American Journal of Physiology – Regulatory, Integrative and Comparative Physiology has revealed that, short bursts of high-intensity exercises are as good for your cardiovascular health as longer exercises of moderate intensity. The study was undertaken by researchers at the McMaster University of Canada and was carried out on 20 healthy men and women.
According to the study, high intensity exercise in short bursts of 30 seconds can improve the function and the structure of your blood vessels, in particular arteries that deliver blood to our muscles and heart. Individuals who are short of time hence no longer need to perform traditional long duration and moderate intensity exercises and can reap the same benefits by performing short duration high intensity exercises.
The research compared individuals who completed interval training using 30 second all out sprint three days a week to a group, which completed between 40 and 60 minutes of moderate intensity cycling five days a week. The comparison revealed that six weeks of intense sprint interval exercise training improved the function and the structure of arteries as much as traditional longer duration endurance exercises.
