Examining Elastic Band Properties for Exercise Prescription: AGUEDA Equations.
Beatriz Fernandez-Gamez, Álvaro Pulido-Muñoz, Marcos Olvera-Rojas and 6 others
PMID 39601439WHAT IT FOUND
Equations from measured Theraband bands estimate load in kilograms from percent stretch.
For all seven colors, the study found Theraband reference values were underestimated, so stated band color may not match actual resistance.
Key findings
01The study created linear equations for seven Theraband colors that estimate resistance in kilograms from percent elongation.
02The authors reported that Theraband reference values were underestimated for all intensities.
03The equations apply only to the tested Theraband bands, which were 200 cm natural rubber latex bands.

What it does not show
The equations were derived only for Theraband bands, so they do not apply to other brands or types of elastic bands. The study did not follow the bands over time, so changes in resistance with wear or repeated use are unknown. The paper reports band measurements, not patient exercise outcomes.
Declared interests
The authors declare no conflicts of interest.
The easy way to misread this
Do not assume these equations prove elastic band exercise improves strength or function. The study measured band resistance only, and the equations apply only to Theraband bands tested here.
