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) × 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.
