Show Notes

  1. How our understanding of lactate has evolved. Why lactate is no longer viewed as a waste product and how the lactate shuttle theory transformed our understanding of energy metabolism, performance, and recovery.
  1. Lactate as a signaling molecule. How lactate influences cellular communication, mitochondrial adaptations, substrate utilization, and the body’s response to training.
  1. Endogenous versus exogenous lactate. The differences between lactate produced during exercise and externally supplied lactate, along with the opportunities and challenges associated with supplementation.
  1. Lactate, brain function, and endurance performance. Why lactate may play an important role in fueling the brain, supporting nervous system function, and influencing fatigue resistance during prolonged exercise.
  1. The future of performance nutrition. Exploring how exogenous lactate could complement existing fueling strategies and open new possibilities for endurance performance and recovery.
