The findings of this study suggest that isometric exercises in individuals with Achilles Tendinopathy (AT) do not cause statistically significant or clinically relevant alterations in pain during a functional task, mechanical pressure pain thresholds or motor output.

The intervention utilized 5 sets of 45-second bent knee (90 degrees) isometric plantar flexor contractions at 70% maximum voluntary contraction (MVC), separated by 2-min rest intervals.
