Note, this isn't for all types of aerobic activity. They're specifically saying that high-intensity aerobics, such as sprinting, are beneficial.

> "Our results indicate that unlike fat-burning exercise, which is relatively moderate, it is a high-intensity aerobic activity that helps in cancer prevention," adds Dr. Gepner. "If the optimal intensity range for burning fat is 65-70% of the maximum pulse rate, sugar burning requires 80-85% - even if only for brief intervals."

Is a daily 7-minute workout enough? I perform it at a very high intensity (40 jumping jacks, 16 push ups).

If your lungs are burning and you're about to collapse after 30 seconds of activity the intensity is about right.

Do 30 seconds high intensity, then 90 seconds low intensity (don't sit down or stand still), repeat 8 times.

Rowing and sprinting works really well.

That would explain the relationship to glucose consumption as noted in the subheading of the article . In events like sprinting, the glycolytic pathway is the primary one.

This also seems somewhat related to the fact that we inject an irradiated glucose analog to make certain types of malignancy show up better on a PET scan (re: Warburg effect)

I am layman but can somebody explain this?

Even if blood sugar level dips during the exercise it comes right back immediately after. Even if you exercise a lot, for majority of the day your blood sugar level should be nominal because nobody can exercise at the effort needed to dip your sugar for very long.

So does this mean cancer cells are so hungry for sugar that they can't survive even a short term dip in sugar availability?

How does one determine maximum pulse rate? I do workouts where I'm constantly at 160-170 bpm for 15 minutes and my lungs aren't burning nor am I about to collapse (aged mid-30s, if that matters)
