Evidence suggests that men who increased their cardiorespiratory fitness (CRF) by more than 3% had a significantly lower risk of prostate cancer incidence (1):
- prospective study; men who completed an occupational health profile assessment including at least two valid submaximal CRF tests, performed on a cycle ergometer, were included
- data on prostate cancer incidence and mortality were derived from national registers
- during a mean follow-up time of 6.7 years (SD 4.9), 592 (1%) of the 57 652 men were diagnosed with prostate cancer, and 46 (0.08%) died
- when participants were grouped as having increased (+3%), stable (±3%) or decreased (−3%) CRF, those with increased fitness also had a reduced risk of prostate cancer incidence compared with those with decreased fitness (HR 0.65, 95% CI 0.49 to 0.86), in the fully adjusted model
In a study of metastatic castrate-resistant prostate cancer (mCRPC) patients (2):
- elevated myokine expressions and greater tumour-suppressive effects of serum after 6 months of periodised and autoregulated supervised exercise was observed in men with mCRPC
- study authors suggest that exercise-induced systemic changes may slow disease progression in men with advanced prostate cancer
