I love HIIT workouts.
- Short duration
- High intensity
- Increased fat loss thanks to EPOC
- Improved anaerobic endurance
- Improved muscular power
- Improved athletic performance
- Honorary BADASS certification
And if that wasn’t enough, it also turns out that HIIT is good for your overall health.
Here’s the latest scientific proof.
Researchers at the University of Glasgow took 10 overweight/obese men and subjected them to three different fitness protocols:
- Sitting on their ass…aka the couch potato workout
- 4 x 30 second full-intensity sprints with 4.5 minute rest periods (HIIT workout)
- A single full-intensity sprint (ES – Extended Sprint workout) designed to be equal to the work done during the HIIT workout.
The day after doing these workouts, the participants…
- had a fasting blood sample taken,
- undertook an oral glucose tolerance test to determine insulin sensitivity index (ISI),
- and had blood pressure measured.
Here’s what they found….
- Total work performed did not differ between the HIIT & ES workouts
- More power was generated during the HIIT workouts than during the ES workouts
- Both the HIIT & ES workouts resulted in increased Insulin Sensitivity compared to the control group
- The HIIT group saw a 63% increase in fat oxidation compared to the control group
- The ES group saw a 38% increase in fat oxidation compared to the control group
And just in case you weren’t aware, increased insulin sensitivity & fat oxidation is exactly what our obese / diabetic society is in dire need of.
And this was after just one workout…imagine how much better things will look after 52 weeks of High Intensity workouts.
