Aerobic or Resistance Training?
A study of 234 obese/overweight adults compared the effects of aerobic training (AT), resistance training (RT) and both aerobic training and resistance training (AT/RT). Researches found the participants in the AT/RT group both increased lean mass (muscle) and decreased body fat, while the RT group did not decrease body fat, and the AT group did not increase lean mass. According to Leslie H. Willis, an exercise physiologist at Duke University Medical Center and the study’s lead author, “If increasing muscle mass and strength is a goal, then resistance training is required. However, the majority of Americans could experience health benefits due to weight and fat loss. The best option in that case, given limited time for exercise, is to focus on aerobic training. When you lose fat, it is likely you are losing visceral fat, which is known to be associated with cardiovascular and other health benefits.”
