A string of studies have been published over the past couple years identifying a strong relationship between High Intensity Interval Training (HIIT) and reduced cardiovascular disease and metabolic syndrome risk. High Intensity Interval Training incorporates periods of exercise above 85% VO2max or HRR in alteration with periods of active or passive recuperation. Evidence suggests that smaller amounts of HIIT are more productive than larger amounts of moderate continuous training. No one is sure, however, how little HIIT and at what exact intensity optimize any variable measured.
Last month a study published in the journal Biomed Central Endocrine Disorders indicated that insulin sensitivity may be improved with as little as 7 minutes of exercise per week. Astounding!
