A population-based cohort study in Finland done by researchers shows physical exercise during leisure time among older adults resulted in lower cardiovascular disease events, lower mortality due to all causes and lower mortality due to cardiovascular disease. Researchers say the benefits of physical exercise were independent of risk factors associated with cardiovascular diseases (CVD) such as cholesterol, smoking, blood pressure (BP) and body mass index (BMI).
Researchers used the National FINRISK Study data which monitored individuals with cardiovascular risk factors. Researchers analyzed 2,456 adults, aged between 65 and 74 years. The researchers collected individual's information related to habits, education, leisure-time physical activity, height, weight, blood pressure (BP) etc. Researchers have done a follow-up study.
The researchers classified leisure time activity into three categories such as
The study results show significant health benefits such as lower cardiovascular disease events, lower mortality due to all causes and lower mortality due to cardiovascular disease in individuals who are under HIGH and MODERATE physical activity categories when compared with LOW physical activity category. Lead author of the study is Dr. Nol C Barengo PhD, Florida International University, Miami and the study findings were published in the Journal of the American Geriatrics Society.
American Heart Association suggests that adults should perform 30 minutes of exercise per day, five times in a week to reduce risk factors associated with multiple diseases including risk associated with cardiovascular disease. A study by the researchers from the University of Leicester shows individuals matching 150 minutes of moderate exercise per week in one or two days also get health benefits such as reducing risks associated with cardiovascular disease.
Researchers studied 63,591 responses from adult individuals between 1994 and 2012 to find out the association between one or two days 150 minutes duration exercise and the mortality risk associated with cardiovascular disease and mortality risk with other causes. Researchers found that
Lead author of the study is Dr. Gary O'Donovan PhD, a researcher in Physical Activity, Sedentary Behavior and Health, University of Leicester and the study findings were published in the JAMA Internal Medicine.
Scientists around the world are trying to find a practical method to stimulate beta cells in pancreas so that they can produce insulin. A study by researchers from the University of Oregon found a protein that boosts insulin production in the guts by microbiota in a zebrafish. When the zebrafish is in larva stage, beta cells in the pancreas multiply with this discovered protein. Researchers named the newly discovered protein as Factor A or BefA.
The newly discovered mechanism in zebrafish offers a different approach in fighting type 1 diabetes (T1D). Researchers are trying to find out the mechanism behind the improvement in the beta cell functionality by microbiota. Researchers are going to conduct clinical tests with the newly discovered mechanism in humans. Researchers say microorganisms in microbiome (microorganisms environment in our body) have the capability to promote good health. Co-author of the study is Karen Guillemin, a biologist, University of Oregon and the study findings were published in the eLife.
