Fat oxidation during exercise refers to the body's process of burning fat for energy during physical activity. Research shows that the body utilizes a greater percentage of fat for fuel at lower exercise intensities, typically within the 60-70% of maximal heart rate or VO2 max range. As exercise intensity increases, the body relies more on carbohydrates for energy, although fat oxidation still occurs. Key Takeaways: The highest percentage of fat is burned for fuel at lower exercise intensities (around 60-70% of max heart rate). At higher intensities, total calorie expenditure is greater, potentially leading to more total fat burned, even if the percentage from fat is lower. Exercise intensity is a key variable in determining fuel utilization during workouts. Exercise zones, often based on heart rate, categorize exercise intensity levels. These zones help individuals train within specific physiological parameters to achieve different fitness goals. Understanding these zones is crucial for optimizing fat burning. - Zone 1 (Very Light): 50-60% of Maximal Heart Rate (MHR). Primarily aerobic, focuses on recovery. Low fat oxidation percentage. - Zone 2 (Light): 60-70% of MHR. The "fat-bu…
