A new study from the United Kingdom finds that sedentary lifestyle may significantly contribute to building fat around internal organs.
The study included MRI scanning of 124 patients who were at risk of developing type 2 diabetes. The researchers also measured how much time these people spent sitting with the help of accelerometers.
Having analyzed the received results, the scientists found that the more time people spent sitting during the day, the more visceral and abdominal fat they had.
Lead study author Dr. Joe Henson, a research associate at the University of Leicester, says: “Using MRI techniques and physical activity monitors we have shown that the more time spent sedentary, the stronger the association with higher level of internal and abdominal fat. This was particularly so if the long periods of sedentary behavior were uninterrupted.”
According to a new study from the USA, people sitting for long periods of time every day are at higher risk of premature death, even if they exercise.
For the study, researchers examined data taken from around 8,000 adults aged 45 and older. The participants were asked to wear accelerometers to measure daily activity levels for a week. The researchers found that participants were sedentary for 77% of their waking hours (approximately 12 hours a day).
Dr. David Alter, head of cardiovascular and metabolic research for the University Health Network-Toronto Rehabilitation Institute in Canada and the author of an accompanying editorial, says: “The lack of activity in our muscles affects our ability to metabolize our sugars efficiently. Over time, our body accumulates excess fat, which can lead to obesity, diabetes, heart disease, cancer, and death.”
According to the researchers from George Washington University, people over 50 who spend 5 hours a day watching TV set may have three times higher risk of disability.
A team of researchers analyzed data from the National Institute of Health’s Diet and Health Study, which tracked people aged between 50 and 71 from six states and metropolitan areas. After all necessary calculations were made, the scientists concluded that nearly 30% of the previously healthy participants reported difficulty walking or being unable to walk at all.
Lead author of the research Dr Loretta DiPietro, chair of the department of Exercise and Nutrition Sciences, says: “Sitting and watching TV for long periods – especially in the evening – has got to be one of the most dangerous things that older people can do because they are much more susceptible to the damages of physical inactivity.”
A new Canadian study suggests that leading a lazy lifestyle without exercising or active recreation connected to the higher risk of developing dementia, as people are genetically predisposed to this disease.
In the study, the researchers analyzed data of more than 1,600 people aged 65 and older who led a sedentary life. And they seemed to have the same risk of developing the condition as they all carried the apolipoprotein E gene mutation. This gene is known to increase the risk of developing dementia.
Jennifer Heisz, the lead researcher and an assistant professor in the department of kinesiology at McMaster University in Hamilton, Ontario, says: “Being inactive may completely negate the protective effects of a healthy set of genes.” However Heisz adds that how exercise may reduce the risk for dementia isn’t known at the present moment.
A new study investigated the impact of a sedentary lifestyle on the biological age of senior women.
Modern science associates the telomere length with ageing and disease. With age, telomeres become shorter until the cells die or transform into oncogenic cells. Short telomeres are connected to cancer, heart diseases, and diabetes.
The team of researchers at the University of California-San Diego, led by Aladdin Shadyab, Ph.D., from the Department of Family Medicine and Public Health at UCSD School of Medicine, examined the effects of a sedentary lifestyle on the age of cells in senior women.
According to the findings of the study, women who exercised for under 40 minutes and spent sitting more than 10 hours per day had biologically older cells compared to women who had been sitting less and exercised more. As the scientists note, low physical activity seemed to account for an eight-year biological age gap between those who exercised and those who did not.
