Recent studies have reported that resistance exercise is an effective method to counteract these metabolic diseases. Objective To analyze the metabolic and physical effects of a 12-week resistance exercise program in 40 sedentary women aged between 30 and 60 years who worked at the University of Concepcion, Los Ángeles, Chile. The study was conducted between September and December, 2013. Materials and methods Participants were randomly assigned to either an experimental group or to a control group.
