High-Intensity Interval Training


       HIIT is an acronym that stands for high intensity interval training. It is the one of the more modern principles of exercise science, being applied now more commonly in performance training, rehabilitation after sport-related injury, as well as neurological rehabilitation.  HIIT is a means by which the subject, athlete, or patient can participate in an elevated intensity or dosage of exercise (weights, speed or resistance training over a shorter total application while realizing similar or greater-man benefits as compared to more moderate levels of intensity carried out for longer periods of time. HIIT has research-proven applications in swimmers, runners and cyclists that has included 40 and up to 60% reduction in training volume while realizing similar benefits to matched subjects that participate in greater volumes (running mileage, swimming yardage, cycling minutes or miles).
       In neurologic rehabilitation applications, subjects that participate in high intensity interval training are able to access the levels of intensity necessary to promote or facilitate Neuroplasticity that would have been otherwise inaccessible to them had they been attempting to achieve moderate levels for longer periods of time. In yet another application, HIIT has been shown to be effective in underwater treadmill-training applications for persons with osteoarthritis of the knees and hips. Persons with OA can expect to realize less pain, greater endurance, greater function, higher quality of life, and more strength through applications of HIIT using the underwater treadmill environment and work against the resistance jets.
