Short Bursts Of Activity Can Reduce Cancer Risk
31 Jul 2023 • People who do 4 to 5 minutes of vigorous physical activity daily can reduce their cancer risk by up to 32%, a new study published in JAMA Oncology says.
- This prospective cohort study involved 22,398 nonexercising adults with a mean age of 62.0 years. During an average follow-up of 6.7 years, 2356 total incident cancer events occurred, with 1084 of them related to physical activity (PA). Most of the very light physical activity (VILPA) occurred in short bouts of up to 1 minute.
- The study found that daily VILPA duration was associated with cancer outcomes in a near-linear manner, with stronger effects observed for PA-related cancer.
- Compared to no VILPA, a median daily VILPA duration of 4.5 minutes (in bouts up to 1 minute) was associated with a 31% to 32% reduction in PA-related cancer incidence and an 18% reduction in total cancer incidence. The minimal dose of VILPA associated with reduced cancer risk was 3.4 to 3.6 minutes per day for both total and PA-related cancer.
In conclusion, even small amounts of VILPA were associated with a lower risk of incident cancer. Daily VILPA could be a promising intervention for cancer prevention, especially in populations that may not be able or motivated to engage in traditional exercise during leisure time.
