MuscleSound Terminology

Glycogen

The primary source of energy used by your muscles. We get glycogen mainly from carbohydrates (sugars and starches) that we eat/drink. Glycogen is the primary ingredient in determining your Muscle Fuel.

Muscle Fuel

This consists mainly of glycogen but also includes other constituent such as protein, carnitine and creatine.

Estimated Fuel Level (EFL)

The level of energy (fuel) stored in your muscles at any given time. MuscleSound uses a ‘fuel tank’ analogy for this measure and, via multiple scans over time, provides a continuously updated ‘percentage full’ Estimated Fuel Level for each muscle.

Muscle Fuel Symmetry (MFS)

The symmetry (balance) of MuscleSound scores between corresponding right and left muscles of the upper or lower body. Such differences have been linked to increased injury risk and performance deficits.

Muscle Fuel Rating (MFR)

The comparison (rating) of an individual’s muscle fuel score with the fuel scores of thousands of individuals in our MuscleSound database. Comparing scores in this way shows what the potential of a muscle fuel score may be. It also answers an important question: “How do my muscles compare to all the others who have been assessed in this way?”

Muscle Energy Status (MES)

A combined value made up of Estimated Fuel Level, and Muscle Fuel Rating. A fully fueled, well rated muscle is at a high Muscle Energy Status, and is at optimal readiness for performance.

Muscle Readiness

An indication of your muscles readiness to perform at its full potential. A fully fueled muscle is at optimal muscle readiness to engage in activity or exercise.

MuscleHealth

The capacity of an individual’s muscle to store, generate, and replenish energy. This is a measure that can be tracked over time.

Muscle Health Index (MHI)

This unique concept is still in development. When completed, it will be expressed as a single number derived from a composite score of Muscle Energy Status, Muscle Structure Status and Body Composition.
