Researcher Martin Gibala, PhD, who along with Izumi Tabata, PhD, et al., have helped bring high-intensity interval training back to the forefront of training for both athlete and novice alike. I have had the pleasure of reading all of Dr. Gibala’s papers on high-intensity interval training (HIIT), so when I saw that his book, The One-Minute Workout, was going to be published this year (Avery Publishers, 2017, 263 pages), I couldn’t wait to get my hands on a copy. The first half of the book he goes into the importance and research history (his and other researchers) of interval-based training. The second half of the book has the actual HIIT workout protocols and “hits” on nutrition as well. As expected it was a great read. One of the training workouts featured in the book (pages 146-148), called the 10-20-30 protocol, is excellent, I have tried it myself and have previously written about it, see here.
The original research was completed on 16 male/female runners who ran 2-4x/week. Eight of the runners kept running as usual (covering about 17 miles in those 2-4 training sessions). The other group of eight runners reduced their training volume by 54 percent and worked out using the 10-20-30 sprint protocol. After a warm-up, the group ran for a minute that included an easy run for 30-seconds, followed by a faster run for 20-seconds and finally a sprint for 10-seconds. They completed this 1-minute run for 3 to 4 intervals with rest between each interval run. Both groups trained for seven weeks. Among other things, the sprint group experienced a 4 percent increase in their VO2 max. The sprint interval group also saw significant changes in performance despite cutting their volume by more than 50 percent.
Try adding this type of interval training into your training program if you’re a runner or maybe if you’re looking to get back into running like I was. After a period of time away from running, I started doing interval training indoors on a treadmill over the course of a month. My goal was to develop a good base with just 10-15 minutes of total running time/session during that first month (total workout time: 20-30 minute training sessions, every other day). As my aerobic capacity improved, I got more into the 10-20-30 jog to sprint protocol during the following month (as my body got use to the stress of running). As the research demonstrated, and I too experienced, the protocol worked beyond expectation, experiencing great results with less time spent working out.
