Exercise and incidence of cancer
- investigation of vigorous intermittent lifestyle physical activity (VILPA) in short bouts (<= 1 and <=2 minutes) incident cancer among nonexercising adults
- in this prospective cohort study of 22,398 self-reported nonexercising adults, a minimum dose of 3.4 to 3.6 minutes of VILPA per day was associated with a 17% to 18% reduction in total incident cancer risk compared with no VILPA
- a median daily VILPA of 4.5 minutes was associated with a 31% to 32% reduction in physical activity-related cancer incidence
- findings of this large cohort study suggest that 3 to 4 minutes of VILPA per day may be associated with decreased cancer incidence risk; thus, VILPA may be a promising intervention for cancer prevention among individuals unable or unmotivated to exercise in leisure time
A cohort study demonstrated that balanced levels of MPA (moderate physical activity), VPA, and MSA (muscle strengthening activity) combined may be associated with optimal reductions of mortality risk (1)
- higher-than-recommended levels of MPA and VPA may further lower the risk of cancer and all-cause mortality, respectively
Association between physical activity (PA) intensity and certain cancer sites, such as breast and colon cancers, is dose dependent and has a greater risk reduction associated with vigorous physical activity (VPA) compared with lower intensities (2)
- vigorous intermittent lifestyle physical activity (VILPA) refers to brief and sporadic (eg, up to 1-2 minutes [min]) bouts of VPA during daily living, eg, bursts of very fast walking or stair climbing (3)
