Why Vigorous Exercise Is 4–10x More Effective Than Moderate (New Evidence)
64 research-tied claims examined: 4 contradicted 7 overstated 4 context 46 supported 3 unverified
3 No source found (not proven false)
Moderate physical activity shows a linear dose-response risk reduction up to about 50 minutes per day, after which additional moderate activity provides no further risk reduction.
"up to about 50 minutes per day, you kind of saw this linear dose response, uh, this risk reduction up to about 50 minutes per day of moderate activity. And then after that, you didn't see more risk reduction basically from getting more moderate activity." (said at 0:32:12)
No published record matching the claim that moderate physical activity shows a linear dose-response risk reduction up to about 50 minutes per day after which additional moderate activity provides no further risk reduction was located; this does not prove the claim false.
Vigorous-intensity exercise induces higher increases in adrenaline, cortisol, and growth hormone than low-intensity exercise.
"obviously with these vigorous intensity activities, you get more adrenaline, more cortisol, more growth hormone. Anything that you get with low intensity activity is sort of just heightened with high-intensity activity" (said at 1:03:42)
No published record matching the claim that vigorous-intensity exercise induces higher increases in adrenaline, cortisol, and growth hormone than low-intensity exercise was located; this does not prove the claim false.
Clinical studies demonstrate that older adults with type 2 diabetes can safely perform Norwegian 4x4 high-intensity interval training at 85% maximum heart rate multiple times per week.
"there are, I mean, hundreds of studies on, let's just keep using the Norwegian 4x4, for example, but adults can do that protocol safely, effectively, several times per week... we had people who were 65 years old with diabetes coming in and they were doing a couple of these 4x4 protocols a week, 85% heart rate max." (said at 1:46:30)
No published record matching the claim that older adults with type 2 diabetes can safely perform Norwegian 4x4 high-intensity interval training at 85% maximum heart rate multiple times per week was located; this does not prove the claim false.
Unverified means no publication matching the claim was located; it does not prove the claim false. Spotted an error? See the corrections policy - disputes from the people quoted are prioritized.
