Long-chain triglycerides have not demonstrated ergogenic benefits before exercise due to their slower digestion and absorption process compared to medium-chain and short-chain triglycerides. When consumed, long-chain triglycerides are often converted into fatty acids and then transported for storage or use, which can take longer to metabolize. This means they do not provide the quick energy availability that athletes may seek right before or during exercise.

In contrast, medium-chain triglycerides are absorbed rapidly and can provide a quick source of energy, potentially enhancing performance in endurance events or prolonged physical activities. Short-chain triglycerides are also quickly metabolized, allowing for efficient energy use. Saturated triglycerides refer more to the structure of the fatty acids rather than their chain length, so while they may not offer specific ergogenic benefits either, they are generally less relevant in the context of energy metabolism during exercise.

Thus, long-chain triglycerides are typically not effective for pre-exercise energy needs due to their metabolic properties.
