BFP is an important indicator of fat levels within the body and reflects an individual's body composition. A high body fat percentage is typically associated with obesity and may increase the risk of health issues such as cardiovascular disease and diabetes. While BMI is a key indicator for assessing whether an individual is underweight, normal weight, overweight, or obese, it does not distinguish between fat and muscle mass. Therefore, when evaluating weight changes and their response to interventions, it is essential to consider body fat percentage alongside BMI. An analysis of the collected data revealed that different exercise interventions significantly impact both BMI and body fat percentage (F(7, 88) = 781.282, \(p\) < 0.001, \(\eta^{2}\) = 0.899; F(7, 88) = 534.876, \(p\) < 0.001, \(\eta^{2}\) = 0.859). As shown in Figure 1, the HIIT-LISS, MICT-LISS, and HIIT-MICT exercise interventions are the most effective for improving participants' BMI, with the mixed approach of high-intensity exercise interspersed with low-intensity exercise being the most effective. Compared to pre-intervention levels, this approach achieves an improvement of up to 5.37%. On the other hand, the alternating intervention of HIIT-MICT-LISS is less effective, only surpassing the LISS intervention. Regarding body fat percentage improvement, the alternating combination of two exercise interventions also shows better results. Notably, continuous HIIT proves more effective in reducing body fat percentage, with a maximum reduction of 5.65%, highlighting the crucial role of high-intensity exercise in improving body fat percentage. \begin{table}

In terms of metabolic health, maintaining low LDL levels and high HDL levels is crucial for good metabolic health. Exercise interventions have a significant impact on the levels of LDL and HDL (F(7, 88) = 37.701, \(p\)! 0.001, \(\eta^{2}\) = 0.75; F(7, 88) = 18.596, \(p\)! 0.001, \(\eta^{2}\) = 0.597). Regular aerobic exercise helps lower LDL levels in the blood, reducing cholesterol accumulation on arterial walls and lowering the risk of cardiovascular diseases. Simultaneously, exercise can increase HDL levels, enhancing cholesterol clearance and further protecting cardiovascular health.
