What is the exercise training method defined by intervals of near-maximal intensity, broken up by relatively short rest periods?

• A. Continuous steady-state training
• B. Fartlek training
• C. High Intensity Interval Training (HIIT)
• D. Intermittent sprint training

Answer: (C)

High Intensity Interval Training is defined by repeating bouts of near-maximal effort followed by short recovery periods. Each intense interval pushes you close to your maximum, typically lasting a short duration, with brief rest or low-intensity recovery in between to allow partial renewal and keep the workout moving at a high overall intensity. This structure yields substantial improvements in aerobic capacity, anaerobic performance, and overall fitness in a shorter time than longer steady workouts. Compared to continuous steady-state training, which maintains a moderate effort for a long time, HIIT emphasizes those high-intensity bursts and built-in rests. Fartlek training mixes pacing in an unstructured way, not necessarily with defined intervals and rest periods. Intermittent sprint training uses sprint efforts with rest but may vary in structure and intensity; HIIT specifically targets near-maximal efforts in a repeatable interval format.
