Even in a very short amount of time, if you focus and exercise intensely, you can fully enjoy the health benefits.

 

If it is difficult for you to allocate a long time for exercise, try short-term workouts to reduce body fat.

You can alternate between high-intensity exercise and low-intensity exercise.

If you only do high-intensity exercise, your body's oxygen levels become insufficient, which impairs the function of mitochondria that produce energy in our body.

At this time, repeatedly engaging in low-intensity exercise replenishes oxygen in the body, allowing the mitochondria to produce energy efficiently.

When mitochondrial function is activated, the body's metabolism becomes more active, preventing fat from accumulating easily.

The method is as follows.

 

It is recommended to repeat running at full speed for 15 seconds followed by walking slowly for 45 seconds.

 

There are research results on what health benefits this method provides.

 

The research team from Curtin University's School of Health Sciences in Australia divided 90 adults aged 18 to 60 into two groups, each practicing different exercise methods for 10 weeks.

 

One group sprinted at full speed for 15 seconds to the point where they couldn't even talk to the person next to them, then

Repeated walking slowly for 45 seconds, 18 times, three times a week.

The other group biked for 45 minutes, five times a week. What was the intensity at that time?

It was of moderate intensity enough to hold a conversation with the person next to me.

 

The results comparing the physical changes of the two groups after 10 weeks,

Both groups showed an average 9% increase in body oxygen levels and a similar reduction in body fat.

 

The reason why the two exercises produced similar effects is,

Even intense exercises like sprinting, even for a short period, cause a shortage of oxygen in the body, prompting a rapid replenishment of oxygen.

Because the heart and lungs are moving vigorously.

 

During exercise, the cardiovascular muscles are strengthened, leading to improved cardiovascular function.

 

However, high-intensity exercise can suddenly raise blood pressure.

People with heart or lung problems should consult a doctor and adjust their exercise intensity accordingly.
