MedicalResearch.com: What is the background for this study? What are the main findings?
Response: It is known that long sitting hours may be detrimental to health and previous studies have suggested associations between sitting time and all-cause mortality.However, it is not known whether physical activity can eliminate the increased risk of death associated with long sitting time.

We found that at least one hour of physical activity every day appear to offset the increased risk associated with more than eight hours of sitting. We also found that those who were physically inactive and sat for less than 4 hours every day were at greater risk compared with those who were physically active and sat for more than 8 hours providing further evidence on the benefits of physical activity.

MedicalResearch.com: What should readers take away from your report?

Response: If you have to sit for long hours during work or transportation it is particular important to also try to be physically active. A little is better than nothing and more than hour of activity appear to offset the increased risk of activity. You do not have to take up sport or go to the gym. Activities such as brisk walking or bicycling are fine.

MedicalResearch.com: What recommendations do you have for future research as a result of this study?

Response: Our results are based on studies from developed countries including North America, Europe, Japan and Australia and it is unknown whether these associations are similar in developing countries.

MedicalResearch.com: Is there anything else you would like to add?

Response: The take home message is physical activity is one of the best cures for almost all non-communicable diseases and  people should be encouraged to sit less and move more and the more the better.

MedicalResearch.com: Thank you for your contribution to the MedicalResearch.com community.
