Summary

Midportion Achilles tendinopathy (MAT) is a common overuse injury of the lower extremity characterized by the presence of pain, restricted function and interruption of sport activities. Conservative management of MAT has been suggested as the first line of treatment. Actually, there are several exercise programs with beneficial effects on pain and function among which high load training stands out. However, this training modality is inherently difficult to implement in certain populations and pathological conditions due to their inability to tolerate this mechanical stress. In this sense, low load training with blood flow restriction (BFR-LLT) emerges as an effective option in producing hypertrophic adaptations with low intensities (30% 1RM). However, this training modality has not yet been studied in tendon pathology. The aim of this study is to evaluate the potential clinical effects of BFR-LLT in comparison with HLT in patients with chronic MAT.

Interventions

OTHER

Low Load Training with Blood Flow Restriction

A 12-cm-wide pneumatic nylon tourniquet will be proximally positioned with a snug fit on each thigh. Previously, arterial occlusion pressure (AOP) will be determined using a handheld Doppler Ultrasound in a standing position for each participant. For training routines, cuff pressure will be set to 50% of each individual´s AOP and will be keep inflated during the entire session including the interset rest period of 1 minute. Between the two exercises, the cuff will be deflated for 3 minutes.

OTHER

High Load Training

All participants in this arm will do two exercises, unilateral dynamic standing and sitting calf-raises, with a training load of 70% 1RM, being progressively increased by 5% every four weeks from 70% to 80%. This protocol will consist of three sets of 6-12 repetitions with a interset rest period of 1 minute and 3 minutes rest between exercises.
