System and method for determining a subject's muscle fuel level, muscle fuel rating, and muscle energy status
Provided is a non-invasive system and method for determining a fuel value for a target muscle and potentially at least one indicator muscle. The method includes receiving an ultrasound scan of a target muscle; evaluating at least a portion of the ultrasound scan to determine fuel value within the target muscle; recording the determined fuel value for the muscle as an element of a data set for the muscle; evaluating the fuel data set to determine a value range; and in response to the range being at least above a pre-determined threshold, establishing a target score for the muscle as based on an upper portion of the value range. The method may be repeated to identify ranges for a plurality of muscles, the muscle with the greatest range being identified as an indicator muscle. Based on these findings the muscles estimated fuel level, fuel rating and energy status may be determined. An associated system is also disclosed.
1. A non-invasive method of determining a fuel level for a target muscle in a subject, comprising:
receiving from the subject a plurality of ultrasound scans from the target muscle over a plurality of ultrasound scanning sessions;
evaluating at least a portion of each ultrasound scan to determine a fuel value;
evaluating collective fuel values for the target muscle to establish a fuel value data set without requiring a biopsy;
receiving from the subject a real time ultrasound scan from the target muscle and establishing a real time fuel value for the target muscle; and
ranking the real time fuel value within the fuel value data set to determine a real time fuel level for the target muscle.
2. The method of claim 1 , wherein the fuel value data set is adjusted to have a range of from 1 to 100, such that:
a fuel value of 1 is a minimum fuel value for the target muscle; and
a fuel value of 100 is a maximum fuel value for the target muscle.
3. The method of claim 2 , wherein the real time fuel level of the target muscle is a number between 1 to 100.
4. The method of claim 1 , further comprising:
comparing the real time fuel level of the target muscle against an established fuel value data set for other individuals; wherein, the established fuel value data set is for the same muscle as the subject's target muscle, and the comparison provides a fuel rating for the subject's target muscle.
5. The method of claim 4 , wherein the other individuals are the same gender as the subject.
6. The method of claim 4 , wherein the other individuals are the same age as the subject.
7. The method of claim 4 , further comprising:
combining the real time fuel level and the fuel rating for the target muscle to establish a composite score, wherein the composite score is a real time energy status for the target muscle.
8. The method of claim 7 , further comprising:
establishing a real time energy status for a contralateral muscle to the target muscle in the subject; and
comparing the real time energy status of the target muscle to the real time energy status of the contralateral muscle to establish a fuel symmetry for the target muscle.
9. The method of claim 7 , further comprising:
establishing an energy status data set for the target muscle; and
ranking the real time energy status for the target muscle within the energy status data set.
10. The method of claim 9 , wherein the ranking is on a low, average and high scale.
11. The method of claim 9 , wherein the ranking is on a numeric scale.
12. A non-invasive method of determining a fuel level of a target muscle in a subject, comprising:
acquiring ultrasound scan images of the subject; taking a plurality of fuel level measurements for the target muscle over time by evaluating the ultrasound scan images;
preparing a fuel tank range from the plurality of fuel level measurements without requiring a biopsy; and
taking a new fuel level measurement on the target muscle and establishing where the new fuel level measurement of the target muscle falls within the fuel tank range.
13. The method of claim 12 , wherein the fuel tank range has a minimum and a maximum that correspond to 0% fuel level and 80% fuel level, respectively.
14. The method of claim 13 , wherein the plurality of fuel level measurements for the target muscle is at least 10, and the plurality of fuel level measurements for the target muscle occurs over at least 6 months.
15. The method of claim 13 , further comprising:
taking a plurality of fuel level measurements for a contralateral muscle of the target muscle over time;
preparing a fuel tank range from the plurality of fuel level measurements for the contralateral muscle; and
taking a new fuel level measurement on the contralateral muscle and establishing where the new fuel level measurement of the contralateral muscle falls within the fuel tank range.
16. The method of claim 15 , wherein:
the fuel level of the target muscle is compared to a fuel level of the contralateral muscle; and
a lack of symmetry between fuel level of the target muscle and the contralateral muscle is indicative of a risk of injury for the target muscle.
17. A method of assessing muscle fuel for a target muscle in a subject, comprising:
acquiring ultrasound scan images of the subject; determining a fuel level for the target muscle using the ultrasound scan image;
comparing the fuel level of the target muscle to a fuel level of muscles in other individuals in a database to obtain a muscle fuel rating; and
combining the fuel level and the muscle fuel rating of the target muscle to obtain a muscle energy status for the target muscle;
wherein:
the muscle energy status provides a muscle readiness for activity; and
the fuel level of the muscles in the other individuals in the database is obtained without requiring a biopsy.
18. The method of claim 17 , wherein the muscle energy status is based on a color indicator.
19. The method of claim 18 , wherein the color indicator corresponds to a low, average and high scale.
20. The method of claim 17 , wherein the subject is a professional athlete.
