A decade or so ago, the training method of high-intensity interval training (HIIT) moved off of the running track and into both hospital-based cardiac rehabilitation programs and fitness center-based extreme fitness programs. This popular method for training, originally developed by Drs. Woldemar Gerschler and Hans Reindell in the 1930s to the 1950s, has stood the test of time and remains an effective method for improving cardiorespiratory fitness.
To accommodate HIIT’s ongoing popularity, this issue of the Journal is devoted to the topic. Four feature articles are provided, each addressing an important aspect of HIIT. We start off with “High-Intensity Interval Training: A Review of Physiological and Psychological Responses,” by Marcus W. Kilpatrick, Ph.D., Mary E. Jung, Ph.D., and Jonathan P. Little, Ph.D. As the title implies, this article not only summarizes the benefits associated with HIIT but also identifies important areas for future research. Michele Olson, Ph.D., FACSM, CSCS, next provides a deeper dive into variations of HIIT, with a special emphasis on the Tabata technique. Her article is titled “Tabata: It’s a HIIT!”
Complementing the exercise aspects of HIIT, it is proper that important nutritional issues be addressed as well. Raquel C. Garzon, M.S., R.D., L.D., and Christopher Mohr, Ph.D., R.D., cover these in “Meeting the Nutritional Demands of High-Intensity Interval Training.” Finally, and as one might expect, HIIT might expose trainers and fitness centers to unique legal concerns, a few of which are discussed in the article by JoAnn M. Eickhoff-Shemek, Ph.D., FACSM, FAWHP, and Margaret C. Keiper, Ph.D., “High-Intensity Exercise and Legal Liability Risks.” My hope is that this issue provides a balance of HIIT topics that helps advance your interaction with clients and patients. Speaking of which, don’t miss the copy-and-share Fitness Focus column in this issue about HIIT for use with your clients and patients.
In addition to the above, I encourage you to read through the other department and column articles in this issue. These are listed in the accompanying box. As always, the authors cover a wide array of topics, each providing a concise focus on material relevant to educating others about health improvement.
For those of you residing in North America, I trust you will enjoy the upcoming fall season…and the warm days and cooler evenings that it brings.
Our associate editors continue to do an outstanding job of providing well-written summaries on a wide variety of topics of importance to the fitness professional.
