It also revealed that the link between sedentary behavior and dementia risk persisted even among participants who were physically active.?It isn?t the time spent sitting, per se, but the type of sedentary activity performed during leisure time that impacts dementia risk,? said study author David Raichlen, professor of biological sciences and anthropology at the USC Dornsife College of Letters, Arts and Sciences.?We know from past studies that watching TV involves low levels of muscle activity and energy use compared with using a computer or reading," he said. "And while research has shown that uninterrupted sitting for long periods is linked with reduced blood flow in the brain, the relatively greater intellectual stimulation that occurs during computer use may counteract the negative effects of sitting.?Researchers used self-reported data from the U.K. Biobank, a large-scale biomedical database of more than 500,000 participants across the United Kingdom, to investigate possible correlations between sedentary le...
