About 40% of people who exercise solely at moderate intensity fail to increase their cardiorespiratory fitness (non-responders).
"but the people who do it through moderate intensity, a brisk walk, which is probably the most common form of exercise, about 40% of people are non-responders to increasing their cardiorespiratory fitness." (said at 0:22:47)
No published record matching the specific claim that approximately 40% of individuals exercising solely at moderate intensity fail to increase cardiorespiratory fitness (non-responders) was located; this does not prove the claim false.
A single human cell can contain thousands of mitochondria.
"And what we know—Except for the erythrocyte, of course. Yeah, and we know now that you can have thousands in one cell" (said at 0:29:09)
No published record matching the specific claim that a single human cell can contain thousands of mitochondria (while erythrocytes contain none) was located; this does not prove the claim false.
Heat exposure increases heart rate and cardiac output to the same degree as moderate to vigorous exercise.
"We mimic exercise, moderate to vigorous exercise, because our heart rate and our cardiac output goes up to the same degree as exercise. That's going to create shear stress in our arteries." (said at 0:35:31)
No published record matching the claim that heat exposure increases heart rate and cardiac output to the same degree as moderate to vigorous exercise 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.
