Cardiorespiratory Fitness Linked to Cancer Risk, Mortality?

Keep on exercising (zone 2, HIIT, etc.) if you want to avoid cancer!

Higher levels of cardiorespiratory fitness (CRF) may offer protection from colon and lung cancer and from lung and prostate cancer mortality among men, a large Swedish cohort study suggests.


  • A prospective cohort study included 177,709 Swedish men (mean age, 42; mean body mass index [BMI], 26 kg/m²) who completed an occupational health profile assessment and were followed for a mean of 9. 6 years
  • CRF was assessed by determining maximal oxygen consumption during an aerobic fitness test, known as a submaximal Åstrand cycle ergometer test.

“The clinical implications of these findings further emphasize the importance of CRF for possibly reducing cancer incidence and mortality,” the authors conclude. “It is important for the general public to understand that higher-intensity [physical activity] has greater effects on CRF and is likely to be more protective against the risk of developing and dying from certain cancers.”
