Arnt Erik Tjønna
Background and activities
My main research area is cardiovascular physiology and physical activity in the prevention and rehabilitation of individuals at risk (metabolic disease / diabetes / obesity) for cardiovascular disease. I has been involved in scientific research since 2002.
