Maximal Fat Oxidation (MFO) is a measure of how efficiently muscles use oxygen during exercise. This study aimed to determine the optimal intensity of exercise for measuring MFO in nonathletic individuals. Fourteen healthy young men participated in the study. They first did a running test to measure their MFO rate. Then, they walked at their most comfortable paces for 30 minutes at two different speeds. The researchers measured various factors like oxygen consumption, heart rate, and perceived effort. The results showed that the highest fat burning during walking occurred when participants walked at an intensity equivalent to about 35.8% of their maximum effort. This suggests that this walking pace might be suitable for evaluating MFO in nonathletic populations.
