Mode: high-intensity interval exercise and continuous endurance exercise: chronic effects. Several research groups compared long-term HIIT with traditional endurance and/or resistance training on weight loss and body composition and the results are inconclusive. Some groups reported no difference in changes in body fat and weight between HIIT and continuous endurance training in overweight/obese individuals [23] or type 2 diabetic patients [24]. However, Keating et al.
showed that continuous aerobic exercise offered greater improvement in fat mass and fat distribution, particularly android fat, than HIIT [25]. Nybo and colleagues showed that endurance exercise reduced body weight and resistance training increased lean mass, with HITT having no impact on body weight and body composition [26]. HITT seems to
be a solution for the “lack of time” barrier for individuals who want to increase physical activity, however its effect on weight loss needs further investigation.
