Moderate exercise can offset the health risks of being sedentary

  Many adults sit for most of the day in addition to sleeping – whether driving to work, going to the office, or returning home to watch TV. A number of studies have previously shown that being sedentary poses certain health risks.  An international team recently published in the British medical journal “The Lancet” reported that they analyzed a number of previous research findings and found that more than one hour of moderate exercise per day can offset the health risks associated with sedentary behavior.  To further explore this issue, scholars from Norway, the United Kingdom, Australia and the United States and other research institutions, a comprehensive analysis of 16 previous research findings, involving data from more than 1 million people.  The researchers defined moderate exercise as walking at a speed of 3.5 miles per hour (1 mile equals 1.61 kilometers) or bicycling at a speed of 10 miles per hour, and accordingly divided the study subjects into four groups, with the lowest group exercising moderately for less than five minutes per day and the highest group for more than 60 minutes per day.  The researchers noted that 60 to 75 minutes of moderate exercise per day would be enough to eliminate the risk of premature death from sitting for more than 8 hours per day. However, three-quarters of the people surveyed were unable to achieve this level of exercise.  The researchers also found that the population surveyed, those who do not move much during the day, regardless of how long they are sedentary, their risk of premature death is 28% to 59% higher than the group of people with the highest level of exercise. In other words, compared with sedentary, the lack of exercise exercise brings higher health risks.  But they also pointed out that the analysis was based on data mainly from people aged 45 and older living in Western Europe, the United States and Australia, and the coverage was not large enough. Nevertheless, the researchers believe that the assessment is more informative than other similar studies before.  One of the report’s authors, Cambridge University professor Ulf Ekron said that many people have to take the car to work every day, and then sit at a desk to work, it is difficult to avoid sedentary, “for these people, we have also repeatedly stressed the importance of exercise, whether it is lunchtime to walk outside, running or cycling to work in the morning, there is an hour or so of exercise time every day is more ideal. If you really can’t do it, even a small amount of exercise every day can help reduce the associated health risks”.
