This continuing education quiz will look deep into the science of high-intensity interval training (HIIT). The fitness industry is seeing a surge of interest in HIIT, a burst-and-recover cycle that can offer a viable alternative to continuous aerobic exercise. HIIT, which pairs quick bouts of high-energy with low-effort rest intervals, is not exactly a new idea; it dates back to as early as 1912. As our knowledge of HIIT has increased, exercise scientists have demonstrated that HIIT can: boost the performance of competitive athletes, improve the health of recreational exercisers, and provide the benefits of continuous-endurance training with fewer workouts. This quiz will cover the body’s cardiovascular, skeletal-muscle and metabolic adaptations to HIIT and compare them with the body’s response to continuous endurance exercise. Go HIIT and go endurance!
After reading this article, readers should be able to:
- Explain program design specifics of HIIT.
- Show a basic educational understanding of the cardiovascular responses and adaptations to aerobic exercise.
- Compare and contrast cardiovascular adaptations to HIIT with cardiovascular adaptations to continuous-endurance training.
- Compare and contrast skeletal-muscle adaptations of HIIT with skeletal-muscle adaptations to continuous-endurance training.
- Compare and contrast metabolic adaptations to HIIT with metabolic adaptations to continuous-endurance training.
