Perform with Dr. Andy Galpin - How Lactate & Metabolism Influence Performance

How Lactate & Metabolism Influence Performance

1 Listener

In this episode, I discuss lactate (or “lactic acid”) and its essential roles in metabolism and athletic performance. Lactate is commonly misinterpreted as the waste product responsible for muscle soreness and exercise fatigue. However, I explain why it is produced, how lactate positively affects multiple organ systems, and its critical function in metabolism and as a signaling molecule.

I explain the concept of metabolic flexibility and how lactate helps cells effectively transition between energy sources (carbs vs. fats). I describe why lactate is essential for mitochondrial health and how different muscle fiber types use lactate. I also discuss how lactate relates to endurance performance and training “zones,” the cause of exercise fatigue, and whether more lactate or lactate supplementation improves exercise performance.

I explain the three I’s (investigate, interpret, intervene) to determine your lactate levels and lactate threshold and how to use different exercise intensities to improve mitochondrial health and reduce fatigue.

This episode will help listeners appreciate the vital role of lactate in overall health and understand how lactate levels should inform training and exercise to improve metabolic flexibility, increase energy, and enhance performance.

How to Enhance Performance With Better Sleep

In this episode, I explain how sleep optimization produces a competitive advantage and the many tools available for improving sleep to maximize athletic performance. I explain how sufficient, high-quality sleep enhances speed, accuracy, reaction time, and competition performance and aids in injury recovery. I also describe why most athletes suffer from chronic suboptimal sleep, the athlete’s sleep paradox, the biochemical reason athletes need more sleep, and the most common sleep disorders affecting athletes.

I explain the importance of optimizing three areas for sleep: duration, quality, and timing. I also discuss how to use sleep extension to improve performance and how to use sleep banking and/or adjust sleep timing during competition training or travel.

I discuss the three I’s (investigate, interpret, intervene) for improving sleep and describe sleep solutions, ranging from free protocols and low-cost wearables to high-precision clinical sleep testing.

Listeners will understand the importance of sleep for performance and how to create a precise, effective sleep program tailored to individual needs and goals for yourself or the athletes you coach.

Avoid Fitness Plateaus, Overtraining & Mis-Timed Performance Peaks

In this episode, I discuss training plateaus, overtraining, and peaking (aka “tapering”) to help you train smart for your goals and effectively use rest to maximize performance.

I discuss training plateaus, the underlying molecular mechanisms that cause plateaus, and how to overcome plateaus by targeting systems and nutrition-based approaches. I describe how overtraining reduces performance, which molecular biomarkers to measure to determine if you are overtrained, and how to recover from overtraining. I also explain how to use peaking (tapering) to significantly enhance performance, when to place a taper relative to competition, and how to effectively taper by reducing volume and increasing rest days.

I explain multiple causes and solutions for diminished performance and describe tracking options for measuring your health, fatigue, and performance. Listeners will learn how high-performance athletes, down to general exercisers, should measure, monitor, and intervene in plateaus, overtraining, and taper effectively.
