Examining Elastic Band Properties for Exercise Prescription: AGUEDA Equations

Abstract

Objective: The objective of this paper is to quantify muscle load using Theraband elastic bands across seven resistance intensities. Methods: Bands were profiled using a force sensor, standardized to 200 cm length, and manually stretched. Measurements for each band were twice recorded at 11 distances and converted to percentages for standardization. Results: Equations derived from Theraband resistance properties were established (kg = ((elastic constant) ± SE) x percentage of elongation). The standard error ranged from 0.0007 to 0.069, while the coefficient of determination ranged from 0.977 to 0.995. Conclusion: This study provides quantification of resistance across various intensities of Theraband elastic band, offering equations for estimating external load.
