Metabolic Parameter Determination via COT Curve Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for characterizing an individual's metabolic response to exercise require multiple separate protocols and equipment, making it difficult to obtain a synthetic mapping of the response, and there is no single protocol for directly quantifying an individual's energetic potential.
Innovation Solution
A method and device that combine muscle response with ventilatory response to exercise, allowing for the calculation of five key metabolic parameters (basal power, threshold metabolic intensity, metabolic resistance, feedback resistance, isometric force, and metabolic merit factor) through a single test protocol using equations like COT=φ02v=a0 +Rmv+Bv and (F+a) (v+b)=c, which can be measured using a test device like a treadmill or bicycle.

Engineering Contradiction Analysis
1Measurement precision
If multiple separate protocols and equipment are used to measure ventilation, heart rate, force-movement speed response, and electromyograms, then comprehensive metabolic characterization can be obtained, but the complexity of the testing procedure increases and a synthetic mapping cannot be achieved
Solution Approach 1:
The patent combines multiple separate measurement protocols (ventilation testing, heart rate monitoring, force-movement speed response, electromyograms) into a single integrated testing procedure. The COT curve methodology synthesizes data from these different measurement domains into one unified metabolic characterization framework, eliminating the need for multiple separate equipment setups and protocols while maintaining comprehensive assessment capability
Solution Approach 2:
The COT curve approach serves as a universal methodology that can characterize multiple aspects of metabolic response (ventilatory, cardiac, muscular) through a single testing protocol. This multi-functional approach allows the same test to provide information across different physiological domains without requiring separate specialized protocols for each measurement type
2Ease of operation
If a single test protocol is used to measure metabolic parameters, then the complexity of the testing procedure is reduced, but the ability to obtain comprehensive synthetic mapping of the response is lost
Solution Approach 1:
The patent transforms the approach by changing the parameter framework from multiple separate measurements to a unified COT curve parameter set. By expressing ventilatory, cardiac, and muscular responses in terms of cost of transport parameters (B, RM, Rfb, Fiso, IT), the system maintains comprehensive information while simplifying the operational complexity through parameter standardization and integration
3Measurement precision
If classical measurement protocols are used separately for ventilation, heart rate, and force-movement speed, then each parameter can be measured accurately, but the individual's energetic potential cannot be directly quantified
Solution Approach 1:
The patent performs preliminary integration of multiple measurement parameters into the COT curve framework before final analysis. By pre-processing ventilation, heart rate, and force-movement speed data through the unified COT parameter model, the system prepares comprehensive information in advance, enabling direct quantification of energetic potential without requiring separate analysis of each classical measurement protocol
