Final answer:
During several hours of exercise, increased lipolysis is NOT likely to occur.
Step-by-step explanation:
During several hours of exercise, increased lipolysis is NOT likely to occur. Lipolysis refers to the breakdown of triglycerides (stored fats) into fatty acids and glycerol. While lipolysis does occur during exercise, it is more prominent during prolonged and low-intensity exercises. High-intensity and shorter-duration exercises primarily rely on the breakdown of glycogen stores in the muscles, leading to the depletion of glycogen stores and increased plasma free fatty acid concentrations. Additionally, exercise typically leads to reduced plasma insulin concentrations and increased cortisol concentrations.
