How to Use & Interpret Blood Tests for High Performance
08/07/24 • 142 min
In this episode, I discuss blood testing for athletic performance. I explain how performance-based blood testing differs from medical or disease-based blood panels and the pros and cons of blood testing for performance.
I explain how to choose specific blood markers based on your performance goals, scenario, and situation. I also discuss the timing, frequency, and preparation for blood tests to increase the accuracy and validity of results. I explain how to contextualize blood test results, interpret reference ranges, and account for the natural variability of blood markers. I also discuss how to improve blood test results through nutrition, behaviors, training, or supplementation.
Listeners of this episode will understand how to determine appropriate blood markers for yourself or your client based on specific training goals and how to interpret blood results so you can look, feel, and perform at your best.

Genetic Testing for Sports Performance
In this episode, I discuss genetic testing for sports and athletic performance. I describe the history of sports genomics and the search for genes that determine strength, endurance, and other performance markers. I explain how to interpret genetic test results, including how many genes determine a trait, the relative influence of a single gene, and the likelihood that a genetic variant produces noticeable performance effects.
I discuss the ethical issues and current limitations of using genetic testing for athletic talent identification. I explain whether your genetic profile can help optimize personalized training, exercise, and nutrition programs to further accelerate performance. I also discuss gene doping, gene editing, gene therapy, and the future of sports genomics.
If listeners have done or are considering genetic testing for personal or client use, this episode will provide a framework for the validity, accuracy, and reliability of current genetic testing and how to interpret their results.

Nutrition to Support Brain Health & Offset Brain Injuries
In this episode, I discuss nutrition and supplementation to reduce the risk of brain injury and enhance brain performance and long-term health. Most brain injuries, including traumatic brain injury (TBIs) and concussion, are not from sports and are actually quite common in non-athletes. I explain what happens in the brain when a TBI occurs and discuss science-supported nutrients to reduce the risk of brain injury, minimize symptoms, and improve recovery.
Summarizing both research and clinical studies, I explain the neuroprotective effects of specific nutrients, including creatine monohydrate, fish oil (DHA and EPA), vitamin B2 (riboflavin), choline, branched-chain amino acids (BCAAs), magnesium, and anthocyanins. I also describe the recommended dosages, frequency, timing, and potential adverse effects and provide options for supplementation and whole-food sources.
Listeners of all ages and backgrounds will benefit from understanding which nutrients can support acute brain injury and natural age-related cognitive decline.
