(select all that apply) Hypothesis: Exercise groups lost adipose tissue and gained muscle mass. Experiment: measure body composition (%fat vs lean tissue) before and after the exercise intervention Hypothesis: Tissues of people who exercise are less sensitive to insulin which favors synthesis of glycogen and lipids. Experiment: Measure glycogen content of muscle biopsies and analyze body composition (%fat vs lean tissue) before and after the exercise intervention Hypothesis: Exercise activated metabolic pathways that promote growth of larger, faster muscle fibers, while simultaneously utilizing more lipids as a metabolic energy source. Experiment: Collect muscle biopsies before and after 6 months of exercise training, measure the sizes of the muscle fibers and contraction speed, and the lipid content of the fibers.
