“…The LIPOXmax occurs at 64 watts (i.e., 42% VO 2max ), and MFO at this level is 282 mg/min. However, the optimal level of fat/carbohydrate oxidation ratio (OLORFOX) [352] occurs at a lower power intensity at 23 watts, so the target heart rate can be proposed as 82 b/min, rather than 92 bpm, if one wants to spare carbohydrates.…”

“…Another recently proposed strategy based on the balance of substrates is to prescribe endurance training, minimizing carbohydrate oxidation by targeting the optimal level of the fat/carbohydrate oxidation ratio (OLORFOX) [352]. This level is calculated from the ratio between fat oxidation and CHO oxidation (Figure 9).…”

“…In this population, 3 years of exercise training targeted toward the OLORFOX helped individuals to lose 11.5 ± 1.5% of their initial weight. We, therefore, propose more thorough evaluation of this new concept of the metabolic targeting level of endurance training in individuals exhibiting this biphasic profile [352]. ).…”

Recent literature shows that exercise is not simply a way to generate a calorie deficit as an add-on to restrictive diets but exerts powerful additional biological effects via its impact on mitochondrial function, the release of chemical messengers induced by muscular activity, and its ability to reverse epigenetic alterations. This review aims to summarize the current literature dealing with the hypothesis that some of these effects of exercise unexplained by an energy deficit are related to the balance of substrates used as fuel by the exercising muscle. This balance of substrates can be measured with reliable techniques, which provide information about metabolic disturbances associated with sedentarity and obesity, as well as adaptations of fuel metabolism in trained individuals. The exercise intensity that elicits maximal oxidation of lipids, termed LIPOXmax, FATOXmax, or FATmax, provides a marker of the mitochondrial ability to oxidize fatty acids and predicts how much fat will be oxidized over 45–60 min of low- to moderate-intensity training performed at the corresponding intensity. LIPOXmax is a reproducible parameter that can be modified by many physiological and lifestyle influences (exercise, diet, gender, age, hormones such as catecholamines, and the growth hormone-Insulin-like growth factor I axis). Individuals told to select an exercise intensity to maintain for 45 min or more spontaneously select a level close to this intensity. There is increasing evidence that training targeted at this level is efficient for reducing fat mass, sparing muscle mass, increasing the ability to oxidize lipids during exercise, lowering blood pressure and low-grade inflammation, improving insulin secretion and insulin sensitivity, reducing blood glucose and HbA1c in type 2 diabetes, and decreasing the circulating cholesterol level. Training protocols based on this concept are easy to implement and accept in very sedentary patients and have shown an unexpected efficacy over the long term. They also represent a useful add-on to bariatric surgery in order to maintain and improve its weight-lowering effect. Additional studies are required to confirm and more precisely analyze the determinants of LIPOXmax and the long-term effects of training at this level on body composition, metabolism, and health.

“…Studies show that endurance-trained people regulate acylcarnitines and glycerophosphocholines differently than untrained people (Weiss et al, 2022). Additionally, Endurance exercise at low to medium intensities that focused on maximising lipid oxidation was shown to impact eating behaviour through epigenetic and regulatory mechanisms, promoting fullness and decreasing the desire to snack (Myzia et al, 2022). Moreover, Long-term LIPOXmax endurance exercise improves fuel metabolism, eating habits, and body composition, reducing weight and improving lipid metabolism (Brun et al, 2022).…”

According to many studies, concurrent training has many benefits for the general fitness of the body, especially fat Loss. In fact, this article include a set of elements that explain the benefits of concurrent endurance-strength training in improving the efficiency of fat Loss, Starting with clarifying the effects of concurrent training on physical fitness, then understanding the balance between Intensity and volume in fat-reducing training, understanding the mechanism of fat metabolism in Concurrent training, as well as the benefits of endurance and strength training, and finally dealing with the benefits of improving Concurrent endurance-strength training by using the Periodization.
