Women typically demonstrate greater fat oxidation during High-Intensity Interval Training (HIIT) protocols compared to men. This difference can be attributed to physiological factors such as hormonal influences and differences in muscle fiber composition. Women generally have a higher percentage of type I muscle fibers, which are more efficient at utilizing fat as a fuel source during aerobic and anaerobic activities. This results in a greater capacity for fat oxidation.

Furthermore, research indicates that women may have different metabolic pathways activated during exercise, leading to an enhanced reliance on fat as fuel, especially in moderate to high-intensity activities. This aspect of women's metabolism can also be influenced by hormonal factors, such as estrogen, which has been shown to affect fat storage and mobilization.

This understanding is important for designing effective exercise programs for both genders, acknowledging the inherent metabolic differences and tailoring HIIT protocols to optimize fat oxidation and overall performance.
