Study Notes
High-Intensity Interval Training (HIIT)
- HIIT involves short bursts of high-intensity exercise followed by brief periods of rest or low-intensity exercise.
- Similar metabolic adaptations are observed in humans after low-volume sprint interval and traditional endurance training.
Physiological Effects of HIIT
- Improves aerobic power and exercise performance (Fox et al., 1973; Burgomaster et al., 2008)
- Increases oxygen deficit during maximal exercise (Medbø et al., 1988)
- Enhances anaerobic capacity (Medbø et al., 1988)
- Stimulates both metabolic and neuromuscular/musculoskeletal systems (Gastin, 2001)
Metabolic Adaptations
- Decrease in phosphagens (PCr and ATP) (Gastin, 2001)
- Decrease in glycogen (production of energy through anaerobic glycolysis) (Gastin, 2001)
- Similar adaptations in human skeletal muscle and exercise performance after HIIT and endurance training (Gibala et al., 2006)
Other Effects of HIIT
- Improves body composition and aerobic capacity in young physically active men and women (Murawska-Cialowicz et al., 2015)
- Increases brain-derived neurotrophic factor and irisin levels at rest and after exercise (Murawska-Cialowicz et al., 2015)
- May require intensity near VO2max to recruit fast-twitch (type II) fibers and achieve maximum heart rate (Altenburg et al., 2007)
