Have Questions about Terminology?

Reviewing our terminology will give you a more in-depth understanding of MuscleSound.

The capacity of an individual’s muscle to store, generate and replenish energy. This unique concept was conceived and developed by MuscleSound. It quantifies the interrelated components contributing to the healthy functioning of muscles and is a measure that can be tracked over time.

The relative percentages of lean body mass and fat mass – both of which are essential components of fitness and health. Also reported is a visual analysis of subcutaneous fat thicknesses at each measurement site.

The primary source of energy used by muscles. Glycogen is mainly obtained from carbohydrates (sugars and starches) in the diet. Glycogen is the primary ingredient in determining Muscle Fuel levels.

This consists mainly of glycogen but also includes other constituents such as carnitine, creatine and, under certain circumstances, protein.

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

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?”

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.

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

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.

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.
