Descripción detallada
Central obesity means having a lot visceral fat, that is, fat located in the abdominal cavity. Visceral fat is a well-established risk factor for cardiovascular disease and all-cause mortality.
Participants will be recruited from the Healthy Ageing Initiative (HAI), an ongoing population-based study that invites all 70-year-olds in Umeå, Sweden, to a health examination. The exercise program will focus is on station-based aerobic exercises and resistance exercises, predominantly with participants' own body weight as resistance. The program is progressive, starting at a moderate pace so that participants learn to perform the exercises properly. The intensity will be aimed at 60-80% of maximal exhaustion, and each exercise bout will last 60 seconds with 20 seconds of rest between bouts. The program was developed by seniors in the bachelor's program in exercise physiology at Umeå University, Sweden.
