Introducing Gradescale: An Endurance Analytics Platform That Shows Its Work
A contribution to the science-curious end of the endurance community
Over the past few months, this corner of the endurance
Snippet #016: Explosive Training Accelerates Neural Drive for Faster Force Production
The Mechanism
Explosive-strength training involves moving moderate loads (40–79% of 1RM) with maximal intended acceleration. This specific stimulus primarily
Entry #018: Top supplements for longevity and ahtletic performance
The traditional demarcation between performance enhancement and longevity medicine is dissolving. Emerging data from 2024 and 2025 indicate that the
Introducing the Calculator Library: 29 Peer-Reviewed Tools, One Transparent Workbench
The Scientist's Notebook is releasing what I believe is the largest free, source-cited collection of endurance calculators on
Snippet #015: Gut Microbiota Adapt to Metabolize Systemic Lactate During Endurance Efforts
Current research identifies the intestinal microbiome as a responsive metabolic organ rather than a static passenger during physical exertion. During
Entry #017: Autonomic Regulation and HRV-Guided Training Architecture
The quantification of recovery remains the most elusive variable in endurance periodization. While external load—measured in watts or pace—
Snippet #014: Autonomic Competition at the Sinoatrial Node Drives HRV
The Mechanism
Heart rate variability (HRV) emerges from the dynamic interplay between sympathetic and parasympathetic signaling at the sinoatrial node,
OpenLab #004: Competing at at an Ironman with Type 1 diabetes - Lucas (coachee) - Part II
Welcome back to the second part of OpenLab #004. In Part I, we covered the foundational physiology of glucose regulation
Entry #016: The Science Of Training Periodization in Endurance Sports (Base, Build, Peak, Taper, Transition)
The fundamental challenge in endurance training architecture is managing the non-linear dose-response relationship between training stress and physiological adaptation. While
Snippet #013: Sodium Bicarbonate Facilitates Hydrogen Ion Efflux to Preserve Contractile Function
During intense exertion, hydrogen ions accumulate within muscle fibers, creating an acidic environment that inhibits the enzymes responsible for energy
