"The method thereby relies on 'the anaerobic energy releasing system almost maximally'."
High-intensity interval training (HIIT) involves short periods of intense exercise followed by rest and recovery. This type of training can help improve cardiovascular health, endurance, and overall fitness.
Definition of High-intensity interval training: Explanation of what HIIT is and how it differs from other forms of exercise.
Benefits of High-intensity interval training: Outline of the benefits of HIIT, including improved cardiovascular health, increased metabolism, and greater fat loss.
HIIT Workouts: A comprehensive guide to HIIT workouts, including types of exercises and intensity levels.
HIIT vs LISS: Comparison between high-intensity interval training and low-intensity steady-state cardio.
Energy systems in HIIT: Explanation of the three energy systems used during HIIT workouts.
Preparation for HIIT: Guidance regarding how to prepare your body for HIIT workouts including warming up, stretching, and hydration.
Intensity and duration of HIIT: Advice on the right intensity and duration of HIIT workouts for different fitness levels.
How to progress with HIIT: Information about progressing with HIIT workouts by increasing intensity, duration, or frequency.
Safety precautions for HIIT: Advice on how to perform HIIT workouts safely and minimize the risk of injury.
Nutrition and HIIT: Explanation of how proper nutrition can support HIIT workouts and enhance their effectiveness.
"The very high level of intensity, the interval duration, and number of bouts distinguish it from aerobic (cardiovascular) activity."
"...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."
"A HIIT workout typically lasts under 30 minutes in total... The times vary, based on a participant's current fitness level."
"Intervals of exercise effort tend to range from 20 to 45 seconds but no longer than 75 seconds."
"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."
"Research has shown that HIIT regimens produced reductions in the fat mass of the whole-body in young women comparable to prolonged moderate-intensity continuous training (MICT)."
"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."
""Near maximal" means reaching 80–100% HRmax."
"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."
"Traditional HIIT initially had been designed to be no longer than 20 seconds on with no more than 10 seconds off."
"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."
"HIIT involves exercises performed in repeated quick bursts at maximum or near maximal effort with periods of rest or low activity between bouts. The body significantly recruits anaerobic energy systems (although not completely to the exclusion of aerobic pathways)."
"HIIT workouts provide... improved glucose metabolism."
"HIIT's crucial features of maximal effort, duration, and short rest periods materially differentiate it from being considered a form of cardiovascular exercise."
"HIIT workouts provide improved athletic capacity and condition."
"Though there is no universal HIIT session duration, a HIIT workout typically lasts under 30 minutes in total."
