- How was the study conducted, and what data was used?
- The study, published in BMC Medicine, involved over 86,000 participants who wore accelerometers to track their physical activity. Researchers analyzed four activity patterns, identifying morning and evening activity as most beneficial for reducing colorectal cancer risk.
- What did the World Cancer Research Fund say about this research?
- Dr. Helen Croker from the World Cancer Research Fund highlighted that while physical activity is known to reduce cancer risk, these findings could lead to more specific recommendations about the timing and patterns of exercise to maximize its preventative effects.
- What did the lead investigator say about the implications of the study's findings?
- Prof. Dr. Michael Leitzmann, lead investigator from the University of Regensburg, emphasized the importance of both the amount and timing of physical activity in cancer prevention. He suggests that further research could lead to more targeted prevention strategies based on these findings.
- Were other factors considered that might affect cancer risk? What were the results?
- The study controlled for factors like smoking and shift work, suggesting that the link between morning and evening activity and reduced colorectal cancer risk is independent of these lifestyle variables. More research is needed to confirm these findings.
- What were the main findings of the study regarding physical activity and bowel cancer risk?
- A study using UK Biobank data found that people with two daily activity peaks (around 8 am and 6 pm) had an 11% lower risk of colorectal cancer compared to those with other activity patterns. This suggests that the timing of physical activity might be crucial in reducing cancer risk.
