Evidence-Based Framework

Clinical Methodology & Scientific Foundations

At VisualBody Lab, we replace guesswork with computation. Every diagnostic tool in our ecosystem is built upon peer-reviewed formulas and clinical research.

1. Biomechanical Modeling

Our Movement Architecture utilizes established kinetic and kinematic models to estimate force production and muscle activation patterns. We prioritize formulas with the lowest standard error of estimate (SEE) in clinical settings.

1RM Prediction

Utilizing Epley and Brzycki algorithms to project maximal strength based on sub-maximal load performance, ensuring safe intensity prescriptions.

Hypertrophy Load

Integration of the Force-Velocity Curve to determine optimal repetition speeds for mechanical tension and metabolic stress targets.

1RM = weight × (1 + reps / 30) The Epley Formula: Clinically validated for calculating estimated one-repetition maximum in compound movements.

2. Metabolic & Nutritional Algorithms

VisualBody’s nutrition pillar is built on predictive thermochemical equations. We analyze Total Daily Energy Expenditure (TDEE) using models that account for lean body mass to provide superior precision for athletes.

  • Mifflin-St Jeor: The current clinical gold standard for estimating Resting Metabolic Rate (RMR) in the general population.
  • Katch-McArdle: Utilized for users with known Body Fat percentages, focusing on Lean Body Mass (LBM) as the primary driver of metabolic activity.
BMR = 370 + (21.6 × LBM) The Katch-McArdle Equation: High-precision metabolic mapping for bio-hackers and high-performance athletes.
