Study: Slow walkers have higher risk of contracting severe COVID-19 SLOW walkers are almost four times more likely to die from COVID-19, and have over twice the risk of contracting a severe version of the virus, according to a team of researchers from the National Institute for Health Research (NIHR) Leicester Biomedical Research Centre led by Professor Tom Yates at the University of Leicester. The study of 412,596 middle-aged UK Biobank participants examined the relative association of body mass index (BMI) and self-reported walking pace with the risk of contracting severe COVID-19 and COVID-19 mortality. The analysis found slow walkers of a normal weight to be almost 2.5 times more likely to develop severe COVID-19 and 3.75 times more likely to die from the virus than normal weight fast walkers. (1)
