New study: Evidence-based guide on the effect of applying the HITT model to Resistance training


As PTs, we know that, the lack of time is the primary reason for people to not exercise regularly. Over the last few years, the aerobic high-intensity interval training (HIIT) has grown in popularity with both PTs and client largely because it promises equal or better results in less time than traditional training programs.

HIIT has traditionally been used with aerobic modalities, involves, high-intensity exercise lasting 30 seconds to five minutes with either rest or lower-intensity work during an exercise session. HIIT workout allows shorter duration workouts, with the results that are equal to, and often better than, traditional moderate-intensity steady-state training.

Furthermore, Lance Dalleck, Ph.D., and his colleagues have investigated the effect of applying the HITT model to Resistance training by looking at 45 men and women (age from 21 to 59 years old). The outcome of this study suggested, HIIT resistance exercise improves muscular fitness in a more rapid timeframe when compared to traditional moderate-intensity.

This study compared the muscular fitness and cardiometabolic outcomes between HIIT resistance exercise group and traditional moderate-intensity exercise group in 3 stages, baseline, midpoint (at week 3) and final week (week 6). The outcome of this study showed, the traditional moderate-intensity exercises group (i.e., chest press and leg extension) there were no significant improvements on muscular fitness and cardiometabolic until after six weeks of training. While, all HIIT resistance exercise group improved the muscular fitness and cardiometabolic significantly at three weeks. The achievement of such results is important, as these may improve the motivation levels of many clients during the early phase of a new workout, when they are typically most prone to frustration and dropout.
