Important dataset, but wrong framing leading to misinformation.
They adjust for volume, then claim intensity is superior.
A huge flaw in the study is the determination of high intensity which for the authors is >6METs which is ~21 mL O₂/kg/min…
So the reality is that this high intensity is in the range of Z1-Z3 for many people…😬…That is not high intensity for most. And low intensity in the study is <6METS which for many is not even a brisk walk or just Z1
To produce intensity:
• ↑ ATP turnover
• ↑ glycolysis
• ↑ lactate
To sustain it:
• mitochondrial capacity
• NAD⁺/NADH balance
• lactate clearance
This study doesn’t even mention metabolism or bioenergetics…
However, the main thing is misinformation as we keep falling into the same trap: either intensity or volume. It’s both!
And more importantly, exercise must be individualized, whether for an elite athlete or a patient.
