People who want to lose weight are better off running than lifting weights -- or even than doing both, researchers at Duke University say.
The researchers compared people who did aerobic exercise -- running, swimming, walking, for instance -- with those who did resistance training such as weightlifting and with people who did both kinds of exercise. Those who got up and moved burned the most fat, they said in the Dec. 15 Journal of Applied Physiology.
“Given that approximately two-thirds of adults in the United States are overweight due to excess body fat, we want to offer clear, evidence-based exercise recommendations that will truly help people lose weight and body fat,” Leslie H. Willis, an exercise physiologist at Duke Medicine and the study’s lead author, said in a statement.
It is the largest randomized trial to look at how the three modes of exercise in overweight or obese adults -- 119 people by the end of the study -- without diabetes changed body composition.
