1) What are the benefits of HIIT interval training?
The best benefit of interval training has a lot to do with heart health. Training at Intervals can boost cardio-respiratory health with a smaller time investment compared to continuous forms of exercise, intervals improving VO2 max, increasing the maximum volume of oxygen the body can use. “The more aerobically fit you are, the better your heart can pump blood, the longer it takes you to get out of breath, and the farther and faster you’re able to bike, press or run” And that can help prevent heart disease.
2) Why does HIIT improve cardio health?
HIIT improves the volume of blood that comes out when the heart contracts (pumps blood), and a major determinant of VO2 max is stroke volume.
The maximum amount of blood that comes out of the heart, is improved by cardio and weight training and evidence shows that when you do interval exercise training, the stroke volume increases drastically
3) Is HIIT the best exercise regimen for weight loss?
There’s no doubt that interval training can be a time-efficient way to burn calories. People can burn considerable amounts of calories in HIIT routines lasting 20-30 minutes, compared to longer continuous exercise routines lasting, say, 50 minutes. The reason for that is that higher-intensity exercise, intervals, results in a greater disturbance of the body’s homeostasis, “and it literally takes more energy and oxygen to return it to normal basal levels.
So if your goal is weight loss, you might consider a longer interval routine, and you definitely want to look at your diet consider calorie consumption, as this will be the overall the decider of whether you reach your goals or not.
70% food – 30% exercise
4) HIIT Afterburn effect?
Many HIIT 99.9% of my HIIT classes will lead to an “afterburn” or “excess post-exercise oxygen consumption” a period of elevated calorie burn after you exercise.
This puts your metabolism into 5thgear and makes you burn calories long after your workout is over,
“The Afterburn Effect is real — but it’s often underrated, for a 25 minutes session of intervals can result in same calorie burn over 24 hours as a 50-minute bout of steady continuous exercise, So that means the Afterburn Effect is greater after the intervals — but it peters out after a while.
