1. Interval training

   High-intensity interval training (HIIT) is a training protocol alternating short periods of intense or explosive anaerobic exercise with brief recovery periods until the point of exhaustion. HIIT involves exercises performed in repeated quick bursts at maximum or near maximal effort with periods of rest or low activity between bouts. The very high level of intensity, the interval duration, and number of bouts distinguish it from aerobic (cardiovascular) activity, because the body significantly recruits anaerobic energy systems (although not completely to the exclusion of aerobic pathways). The method thereby relies on "the anaerobic energy releasing system almost maximally".Although there are varying forms of HIIT-style workouts which may involve exercises associated with both cardiovascular activity and also resistance training, HIIT's crucial features of maximal effort, duration, and short rest periods (thereby triggering the anaerobic pathways of energy production) materially differentiate it from being considered a form of cardiovascular exercise. Though there is no universal HIIT session duration, a HIIT workout typically lasts under 30 minutes in total as it uses the anaerobic energy systems which are typically used for short, sharp bursts. The times vary, based on a participant's current fitness level. Traditional HIIT initially had been designed to be no longer than 20 seconds on with no more than 10 seconds off; however, intervals of exercise effort tend to range from 20 to 45 seconds but no longer than 75 seconds, at which point the aerobic system would then kick in.HIIT workouts provide improved athletic capacity and condition as well as improved glucose metabolism. Compared with longer sessions typical of other regimens, HIIT may not be as effective for treating hyperlipidemia and obesity, or improving muscle and bone mass. However, research has shown that HIIT regimens produced significant reductions in the fat mass of the whole-body in young women. Some researchers also note that HIIT requires "an extremely high level of subject motivation" and question whether the general population could safely or practically tolerate the extreme nature of the exercise regimen.Sprint interval training (SIT) is an exercise conducted in a similar way to HIIT, but instead of using "near maximal" effort for the high-intensity periods, "supramaximal" or "all-out" efforts are used in shorter bursts. In physiological terms, "near maximal" means reaching 80–100% HRmax, while "supramaximal" means a pace that exceeds what would elicit VO2 peak. SIT regimens generally include a lower volume of total exercise compared with HIIT ones as well as longer, lower activity recovery periods and creates a greater homeostatic disturbance. Both HIIT and SIT fall into the larger class of interval training. Distinction between the two is not always maintained, even in academia: for example, Tabata describes his 170% VO2 max regimen as "supermaximal", but does not use the term SIT.

1. Interval training

   Interval training is a type of discontinuous physical training that involves a series of low- to high-intensity exercise workouts interspersed with rest or relief periods. The high-intensity periods are typically at or close to anaerobic exercise, while the recovery periods involve activity of lower intensity. Interval training can be described as short periods of work followed by rest. The main aim is to improve speed and cardiovascular fitness. Interval training can refer to organization of any cardiovascular workout, and is prominent in training routines for many sports. It is a technique particularly employed by runners, but athletes from several backgrounds have been known to use this type of training.

Examples of interval training in a Sentence

1. David Siik:

   It’s a big calorie burn-- but when you do the balanced version of it you also strength train your body, you get a tighter stomach and the cardiovascular benefits from doing interval training is just tremendous.

2. Richard Isaacson:

   In our work, we have found that certain people need to really commit to their exercise program to demonstrate effects on the memory domain, for example, people with one or more copies of the APOE4 genetic variant need to participate in more intense cardiovascular exercise programs, such as high-intensity interval training on a regular basis, to show positive effects.

3. Sreekumaran Nair:

   Exercise training, especially high intensity interval training, enhanced the machinery (ribosomes) to produce proteins, increased the production of proteins and enhanced protein abundance in muscle.

4. David Siik:

   It’s the running definition of HIIT (high intensity interval training)—so HIIT training but done in running.
