RESEARCH ON HIGH-INTENSITY INTERVAL TRAINING
read moreThere is a growing body of research showing that HIIT leads to faster physiological adaptations
and indicating that it’s a less time-consuming method to gain the desired results compared to
following a more long-term MICT (Moderate intensity continuous training) program (Gibala,
2007).
Gibala (2007) conducted a study using the Wingate laboratory fitness test (on a cycle
ergometer) to examine the rapid physiological alterations that occur in athletes’ bodies. He
found great improvements in the body’s capacity for aerobic energy metabolism (VO2 max: the
ability to use O2 more effectively) and exercise capacity after HIIT. Using a “percutaneous
needle biopsy technique,” they also found substantial improvements in the skeletal muscle’s
oxidative capacity (increased activity and number of mitochondrial proteins) after only 2 weeks
of HIIT. Open the lesson to download the full PDF.
