Both high intensity (HI) and low-to-moderate intensity (LMI) exercise significantly reduce cancer-related fatigue, with no statistically significant difference between the two intensities.
If you are a cancer survivor recovering from treatment, you can choose either high or low-to-moderate intensity exercise to fight fatigue. Both work equally well. Focus on consistency (twice weekly supervised + home activity) rather than pushing for maximum intensity, as this reduces fatigue without the higher risk or discomfort of HI training.
HI and LMI exercise significantly reduced general and physical fatigue and reduced activity (MFI subscales) compared to WLC, with no significant differences between both interventions.
Why this rating
Large RCT (n=277), blinded outcome assessment, intention-to-treat analysis, but self-reported fatigue measures.

- High intensity (HI) exercise yields larger improvements in cardiorespiratory fitness (peakVO2) than low-to-moderate intensity (LMI), suggesting a dose-response relationship, although the difference was not statistically significant.Good
- High intensity (HI) exercise improves global quality of life and reduces anxiety more effectively than wait-list control, whereas low-to-moderate intensity (LMI) does not show significant benefits for these specific psychological outcomes compared to control.Good
