In this episode, Rick discusses the differences in Sprint Interval Training (SIT) and High-Intensity Interval Training (HIIT) and the benefits of both including:

- Time efficiency

- Health and fitness benefits

- Aerobic and anaerobic performance

- Better fat oxidation

- Lower blood pressure

- Increased insulin sensitivity

- Optimized hormonal responses

- Weight loss

- Decreased in abdominal weight

- Increased EPOC

That's an impressive list and by no means exhaustive.

HIIT work to rest ratio is often seen as 1:1, 1:2, and 1:3

Sprint interval training involves an all-out effort for shorter durations and longer rest. SIT work to rest ratio is often seen as 1:8 with some researchers indicated that rest is still too short! The following workout may be seen during SIT:

•(1)30:240 (4×30 s bouts, 240 s [4 mins] recovery);

•(2) 15:120 (8×15 s bouts, 120 s [2 mins] recovery);

•(3) 5:40 (24×5 s bouts, 40 s recovery)

(Islam et al, 2017)

This episode contains quite a bit of research (thank you Dr. Brian Oddi) and shows empirically that the calories expended in HIIT and Sprint versus moderate-intensity training can provide increased weight loss from abdominal and visceral fat stores. Tune in and see what all the buzz is about with HIIT and Sprint training.
