Extramyocellular lipids (EMCL) are found within the muscle tissue and are a type of lipid that can serve as an energy source for skeletal muscle, especially during prolonged exercise. The relationship between EMCL and muscular performance is significant because higher levels of EMCL are often seen in individuals who are less active or who have reduced muscle function.

Research suggests that an inverse association exists between EMCL levels and muscular performance, especially in the context of athletes. This means that as EMCL levels increase, muscular performance tends to decrease. This can be important for athletes who rely on optimal muscle function for performance outcomes. Understanding this relationship helps in developing effective nutrition and training strategies for enhancing athletic performance.

In contrast, younger athletes may have a different metabolic profile, and intense training typically leads to a greater utilization of fats, including EMCL, rather than their accumulation. Endurance athletes often have adaptations that allow them to utilize fat more efficiently, possibly resulting in lower levels of EMCL in correlation with better performance metrics. Therefore, while EMCL levels can provide insights into metabolic health, the relationship with performance is primarily negative.
