Which of the following training methods is most effective for improving the efficiency of fat burning pathways?

Long-duration continuous training is particularly effective for improving the efficiency of fat burning pathways because it primarily engages the aerobic energy system. This type of training involves performing exercises at a steady, moderate intensity for an extended period of time, such as jogging or cycling for 30 minutes or longer.

During prolonged aerobic exercise, the body's reliance on fat as a fuel source increases, especially once glycogen stores are depleted. This method encourages adaptations in the muscles and cardiovascular system that enhance the body's ability to oxidize fat, ultimately improving mitochondrial density, capillary development, and the enzymes involved in fat metabolism.

Furthermore, sustained moderate-intensity exercise can improve overall aerobic endurance, which in turn supports better fat utilization during both exercise and rest. These physiological adaptations are key to enhancing the efficiency of the fat burning pathways in the body.
