Entry #004: The ergogenic potential of caffeine and sodium bicarbonate in endurance events

Hi Endurance Enthusiast, The pursuit of marginal gains in endurance performance often leads athletes toward the pharmaceutical cabinet of evidence-based ergogenic aids. Among the most rigorously studied are caffeine and sodium bicarbonate—two substances that target the physiological limiters of endurance through distinct, yet potentially complementary, pathways. While caffeine operates

Entry #003: How to prepare for a cycling race, pre-race fueling timeline, 24 hours to the start

Hi Endurance Enthusiast, Now that we have talked about the long-term aerobic development required to build your engine, we need to address the structural integrity of the chassis before you take it to the redline. Too often, I see athletes invest months in meticulous Zone 2 volume and threshold/Vo2

Entry #002 - The interaction between aerobic and anaerobic energy systems during endurance efforts

Hi Endurance Enthusiast, We need to address a fundamental misconception in training architecture: the idea that your energy systems operate like light switches—flicking from "aerobic" to "anaerobic" the moment you cross a specific heart rate or pace. This sequential view of physiology is outdated and

Entry #001 - Welcome to the Lab

Hi Endurance Enthousiast, Most training advice is based on anecdotes and marketing. This is where we change that. I’m Dr. Thomas Mortelmans, and I started The Scientist’s Notebook because the gap between sports science research and what athletes actually do is far too wide. You are joining as
