A meta-analysis of data from over one million people, published on July 27th in a new Lancet Series ahead of the 2016 Summer Olympic Games, emphasize the importance of physical activity to attenuate the harmful effect of sitting time.
The researchers classified individuals into four groups according to how active they were, less than 5 mins a day, up to 60-75 mins a day for the most active. The study suggest that doing at least one hour of moderate intensity physical activity per day such as brisk walking at 5.6 km/h or cycling at 16 km/h, may attenuate the increased risk of death associated with sitting for 8h a day. Furthermore authors’ recommendations are superior to World Health Organization guidelines, which recommend at least 150 minutes of physical activity per week.
If we are active enough, it is not necessary to go to the gym for one hour per day, according to Ulf Ekelund, lead author (Norwegian School of Sport, Norway and the University of Cambridge, UK).
