High-Intensity Interval Training (HIIT) is an essential component for enhancing endurance performance in athletes, though the optimal intensity distribution and specific prescription remain unclear.
For endurance athletes, HIIT is non-negotiable for performance gains, but you must balance it with moderate volume. Do not prescribe HIIT in isolation; integrate it into a broader program (pyramidal or polarized) to avoid overtraining. The exact type of HIIT (short vs. long intervals) should be periodized based on the specific sport and competition phase.
HIIT is considered an essential training component for the enhancement of athletic performance, but the optimal intensity distribution and specific HIIT prescription for endurance athletes is unclear.
Why this rating
Based on a perspective review citing multiple systematic reviews and meta-analyses, though noting gaps in elite athlete RCTs.

- In a health context, High-Intensity Interval Training (HIIT) is a viable and effective method to improve cardiorespiratory fitness and reduce morbidity/mortality risk, often superior to Moderate-Intensity Continuous Training (MICT) when volume is matched.Good
- Sprint Interval Training (SIT), a variant of HIIT involving near-maximal to 'all out' efforts, can improve endurance performance in highly trained athletes by enhancing fatigue resistance and durability.Moderate
