Resumen
Background: Although evidence shows the positive health effects of physical activity, most of the adult population
in Colombia are sedentary. It is, therefore, important to implement strategies that generate changes in lifestyle
behaviours. This protocol describes a study in which we will compare the effects of 12 weeks of high-intensity

Background: Although evidence shows the positive health effects of physical activity, most of the adult population
in Colombia are sedentary. It is, therefore, important to implement strategies that generate changes in lifestyle
behaviours. This protocol describes a study in which we will compare the effects of 12 weeks of high-intensity
interval training (HIIT), resistance training (RT) or combined training (HIIT + RT) on the improvement of body
composition, endothelial function, blood pressure, blood lipids, and cardiorespiratory fitness in a cohort of
sedentary, overweight adults (aged 30–50 years).
Methods/design: Sixty sedentary, overweight adults attending primary care in Bogotá, Colombia will be included
in a factorial randomised controlled trial. Participants will be randomly assigned to the following intervention
groups: (1) non-exercise group: usual care with dietary support, (2) HIIT group: 4 × 4-min intervals at 85–95 %
maximum heart rate (HRmax) (with the target zone maintained for at least 2 minutes), interspersed with a 4-min
recovery period, at 65 % HRmax, (3) RT group: completing a resistance circuit (including upper and lower muscle
groups) as many times as needed according to subject’s weight until an expenditure of 500 kcal at 40–80 % of
one-rep max (1RM) has been achieved, and (4) combined group: HIIT + RT. The primary end point for effectiveness
is vascular function as measured by flow-mediated vasodilatation 1 week after the end of exercise training.
Discussion: The results of this study will provide new information about the possible effect of the programme in
improving the cardiometabolic health of overweight adults, making a more efficient use of an adult’s resources
over time. [--]
