The effect of exercise training modalities on the morphological and mechanical properties of the achilles tendon: a systematic review and network meta-analysis.

Therefore, this finding needs to be interpreted with caution until larger, adequately powered head‒to‒head trials can confirm whether the small numerical benefits attributed to gait retraining translate into statistically and practically significant tendon adaptations. 4.3 AT force and stress Among the studies included in this review, all 4 investigations of long-term isometric plantar flexion contraction training reported significant increases in AT force, notably when protocols met intensity targets (55%–90% MVC/55% 1RM) and exposure targets
