     Summary:   
         A new study suggests that reducing daily sedentary time can have   
         a positive effect on the risk factors of lifestyle diseases in   
         only three months. Spending just one hour less sitting daily and   
         increasing light physical activity can help in the prevention of   
         these diseases.   
      
      
      
   FULL STORY   
   ==========================================================================   
   A new study suggests that reducing daily sedentary time can have a   
   positive effect on the risk factors of lifestyle diseases already in   
   three months.   
      
   Spending just one hour less sitting daily and increasing light physical   
   activity can help in the prevention of these diseases.   
      
      
   ==========================================================================   
   Type 2 diabetes and cardiovascular diseases are the most common chronic   
   diseases globally. The risk of developing these diseases is increased   
   particularly by overweight caused by physical inactivity and unhealthy   
   diet, and metabolic disorders often associated with it.   
      
   Regular exercise is well known to be beneficial in weight management   
   and disease prevention. However, many adults do not meet the weekly   
   recommendation of 2.5 hours of moderate-intensity exercise, and the   
   majority of the day is typically spent sitting.   
      
   In an intervention study of the Turku PET Centre and the UKK Institute   
   in Finland, the researchers investigated whether health benefits can   
   be achieved by reducing daily sedentary time during a three-month   
   intervention period. The research participants were sedentary and   
   physically inactive working-age adults with an increased risk of type   
   2 diabetes and cardiovascular diseases.   
      
   The researchers compared two groups: the intervention group was guided   
   to reduce their sitting time by one-hour per day through increasing   
   standing and light-intensity physical activity, and the control group   
   was instructed to maintain their usual habits and sedentary lifestyle.   
      
   "What makes our research design unique is that sedentary time and physical   
   activity of both groups were measured with accelerometers throughout   
   the entire three-month period, whereas in earlier studies activity has   
   typically been measured only for a few days at the beginning and end of   
   the study period. This makes it possible to receive more information on   
   the actual behaviour changes over a longer time period," says Doctoral   
   Candidate Taru Garthwaite from the University of Turku in Finland.   
      
   The intervention group managed to reduce sedentary time by 50 minutes   
   per day on average, mainly by increasing the amount of light- and   
   moderate-intensity physical activity. In the three-month period, the   
   researchers observed benefits in health outcomes related to blood sugar   
   regulation, insulin sensitivity and liver health in the intervention   
   group.   
      
   "It is an encouraging thought that health benefits can be achieved   
   by reducing the time spent sitting and increasing the amount of even   
   light-intensity physical activity. For many, this may be an easier   
   starting point than increasing actual exercise," says Garthwaite.   
      
   Particularly beneficial for physically inactive individuals It is likely   
   that people who do not meet the weekly physical activity recommendations   
   will benefit the most from replacing sedentary time with light physical   
   activity. However, reducing sedentary time is probably not enough in   
   itself to prevent diseases if the person has several risk factors of   
   diabetes and cardiovascular diseases.   
      
   "Reducing the time spent sitting might still slow down the development of   
   these diseases, but greater benefits can of course be gained by increasing   
   the amount or intensity of physical activity in addition to sitting less,"   
   encourages Garthwaite.   
      
   The next step for the researchers is to study how changes in daily   
   activity and sedentary time affect energy metabolism and body composition   
   in addition to the risk factors of diabetes and cardiovascular diseases   
   during a six-month study period.
