A little morsel of an episode on exercise snacks and Vigorous Intermittent Lifestyle Physical Activity, known as VILPA. Along with a handful of scientists around the world, such as Emmanuel Stamatakis and Jon Little, Marty is leading research into the health benefits of short, vigorous bouts of exercise that are scattered through the day.
One key finding is that just four minutes of vigorous physical activity per day can decrease risk of all-cause mortality by 25%—which those of us at Exercise Science find remarkable.
So in our eighth episode, Stu leads Marty through a discussion of the ongoing and future research into the benefits of short, vigorous bouts of physical activity. The guys discuss:
—What’s the difference between exercise snacks and VILPA?
—What health benefits are provided by short, vigorous bursts of exercise?
—What are some examples of great exercise snacks that anyone can do?
—What’s the shortest amount of exercise that will make a difference to one’s health?
Finally, we explore the idea that exercise snacks and VILPA may be able to liberate physical activity from the confines of planned gym visits that require special clothing and fancy equipment.
Traditional guidelines have not done much to get more people exercising. In this episode, Stu and Marty explore their ultimate aim of getting more people engaging in strength and cardio with shorter, less-structured bouts of physical activity.
