muscle damage with symptoms of delayed onset muscle soreness), we decided to use a careful and safe progression of eccentric training
(40) Compared with a standard exercise regimen without eccentric strength training, use of eccentric training
improves such clinical measures as pain intensity and disability status, as it decreases tendon thickness and aids in recovering homogenous tendon structure.
Preventive effect of eccentric training
on acute hamstring injuries in men's soccer: A cluster-randomized controlled trial.
In recent years, the eccentric training
program, Extracorporeal Shock Wave Therapy, Deep friction massage, Sclerosing Agents and Aprotinin injection, Electrocoagulation, Prolotherapy (Intratendinous hyperosmolar dextrose), Ultrasound and Low-Level Laser Therapy, Topical Glyceryl Trinitrate, and platelet rich plasma (PRP) injections are introduced to treat Achilles tendinopathy.
The purpose of this study was to compare the effects of an eccentric training
program to a concentric training program on the morphological and mechanical properties of the knee extensor muscle-tendon unit in the elderly in an attempt to improve our understanding of the muscular adaptations to resistive exercises in this population.
Prentice stated "In an eccentric contraction, the resistance is greater than the muscular force being produced, and the muscle lengthens while producing tension." (18) Eccentric training
(also known as negative work) is an exercise in which the muscles lengthen during contraction and provide braking and control mechanisms for limb movement.
for the treatment of tendinopathies.
(23,24) Furthermore, the technique of eccentric training
has been refined to more effectively treat PT.
However, that was a pilot study evaluating the effect of eccentric training
and not a randomized study comparing the effects of different treatment regimens.

Thus, an acute bout of eccentric exercise induces a marked proinflammatory response, while an eccentric training
program attenuates the activation of different signaling pathways involved in inflammatory processes [6-8].
However, due to the unnatural nature of eccentric training
with using isokinetics, as well as the risks associated with supra-maximal loads we should be cautious of inferring practical application from this research.
