   FULL STORY   
   ==========================================================================   
   One in ten early deaths could be prevented if everyone managed at least   
   half the recommended level of physical activity, say a team led by   
   researchers at the University of Cambridge.   
      
      
   ==========================================================================   
   In a study published today in the British Journal of Sports Medicine,   
   the researchers say that 11 minutes a day (75 minutes a week) of   
   moderate-intensity physical activity -- such as a brisk walk -- would   
   be sufficient to lower the risk of diseases such as heart disease,   
   stroke and a number of cancers.   
      
   Cardiovascular diseases -- such as heart disease and stroke -- are the   
   leading cause of death globally, responsible for 17.9 million deaths per   
   year in 2019, while cancers were responsible for 9.6 million deaths in   
   2017. Physical activity -- particularly when it is moderate-intensity --   
   is known to reduce the risk of cardiovascular disease and cancer, and the   
   NHS recommends that adults do at least 150 minutes of moderate-intensity   
   activity or 75 minutes of vigorous-intensity activity a week.   
      
   To explore the amount of physical activity necessary to have a beneficial   
   impact on several chronic diseases and premature death, researchers from   
   the Medical Research Council (MRC) Epidemiology Unit at the University of   
   Cambridge carried out a systematic review and meta-analysis, pooling and   
   analysing cohort data from all of the published evidence. This approach   
   allowed them to bring together studies that on their own did not provide   
   sufficient evidence and sometimes disagreed with each other to provide   
   more robust conclusions.   
      
   In total, they looked at results reported in 196 peer-reviewed articles,   
   covering more than 30 million participants from 94 large study cohorts, to   
   produce the largest analysis to date of the association between physical   
   activity levels and risk of heart disease, cancer, and early death.   
      
   The researchers found that, outside of work-related physical activity,   
   two out of three people reported activity levels below 150 min per week   
   of moderate- intensity activity and fewer than one in ten managed more   
   than 300 min per week.   
      
   Broadly speaking, they found that beyond 150 min per week of   
   moderate-intensity activity, the additional benefits in terms of   
   reduced risk of disease or early death were marginal. But even half   
   this amount came with significant benefits: accumulating 75 min per   
   week of moderate-intensity activity brought with it a 23% lower risk of   
   early death.   
      
   Dr Soren Brage from the MRC Epidemiology Unit said: "If you are someone   
   who finds the idea of 150 minutes of moderate-intensity physical activity   
   a week a bit daunting, then our findings should be good news. Doing some   
   physical activity is better than doing none. This is also a good starting   
   position -- if you find that 75 minutes a week is manageable, then you   
   could try stepping it up gradually to the full recommended amount."   
   Seventy-five minutes per week of moderate activity was also enough to   
   reduce the risk of developing cardiovascular disease by 17% and cancer   
   by 7%. For some specific cancers, the reduction in risk was greater --   
   head and neck, myeloid leukaemia, myeloma, and gastric cardia cancers   
   were between 14-26% lower risk.   
      
   For other cancers, such as lung, liver, endometrial, colon, and breast   
   cancer, a 3-11% lower risk was observed.   
      
   Professor James Woodcock from the MRC Epidemiology Unit said: "We   
   know that physical activity, such as walking or cycling, is good for   
   you, especially if you feel it raises your heart rate. But what we've   
   found is there are substantial benefits to heart health and reducing   
   your risk of cancer even if you can only manage 10 minutes every day."   
   The researchers calculated that if everyone in the studies had done the   
   equivalent of at least 150 min per week of moderate-intensity activity,   
   around one in six (16%) early deaths would be prevented. One in nine   
   (11%) cases of cardiovascular disease and one in 20 (5%) cases of cancer   
   would be prevented.   
      
   However, even if everyone managed at least 75 min per week of moderate-   
   intensity physical activity, around one in ten (10%) early deaths would   
   be prevented. One in twenty (5%) cases of cardiovascular disease and   
   nearly one in thirty (3%) cases of cancer would be prevented.   
      
   Dr Leandro Garcia from Queen's University Belfast said: "Moderate activity   
   doesn't have to involve what we normally think of exercise, such as sports   
   or running. Sometimes, replacing some habits is all that is needed. For   
   example, try to walk or cycle to your work or study place instead of   
   using a car, or engage in active play with your kids or grand kids. Doing   
   activities that you enjoy and that are easy to include in your weekly   
   routine is an excellent way to become more active."  The research was   
   funded by the Medical Research Council and the European Research Council.   
      
   What counts as moderate-intensity physical activity?  Moderate-intensity   
   physical activity raises your heart rate and makes you breathe faster,   
   but you would still be able to speak during the activity.
