There are many studies that show that aerobic and resistance (muscle) training improve abdominal fat distribution, liver fat content, and increased sensitivity to insulin in the liver and the muscles. There has been no studies just looking at only muscle training on insulin sensitivity in teens until recently. In the November journal of Medicine and Science in Sports and Exercise®, a group of researcher examined the effect of resistance training in a small group obese non-diabetic hispanic teens. The average age of the teens were 15 years old, average BMI was 35, and 40% body fat; they were put through a 12 week resistance training program exercising all major muscle groups twice a week for one hour each session. At the beginning of the study and completion of the study their total body fat and liver fat was measured by MRI, insulin sensitivity at the muscles and liver were also measured.
