Who wouldn’t spend less time working out and reap the same (or better) benefits, and burn the same (or even more) calories???! ?Does this make any sense to you at all (ah-hem, 26.2 peeps)??? Love this article – here’s an excerpt.
The fitness industry is seeing a surge of interest in high-intensity interval training (HIIT), a burst-and-recover cycle that can offer a viable alternative to continuous aerobic exercise. According to http://www.ideafit.com/fitness-library/hiit-vs-continuous-endurance-training-battle-of-the-aerobic-titans , HIIT, which pairs quick bouts of high-energy exercise with low-effort rest intervals, is not exactly a new idea. As early as 1912, the Finnish Olympic long-distance runner Hannes Kolehmainen was using interval training in his workouts (Billat 2001). As our knowledge of HIIT has increased, exercise scientists have demonstrated that HIIT can
- boost the performance of competitive athletes;
- improve the health of recreational exercisers; and
- provide the benefits of continuous-endurance training with fewer workouts.
The standard way to improve cardiovascular fitness is to increase the volume of exercise—for example, with longer runs or bike rides, or more time on an aerobic machine. HIIT is intriguing because, according to current research, it can yield a broad range of physiological gains, often in less time than high-volume continuous exercise (Daussin et al. 2008).
