Extreme athletes may face increased healthcare costs from additional screening procedures and potential treatments. Could reduce participation in ultramarathons/marathons if causation confirmed, affecting fitness industry revenue. Broader population may demand more frequent colonoscopies despite moderate exercise benefits.
Health authorities may need to revise screening guidelines for endurance athletes. Sports medicine organizations may issue new recommendations. Insurance companies could adjust coverage for preventive colonoscopies in athletic populations. Regulatory bodies may require additional research before policy changes.
