We have previously demonstrated that eccentric exercise results in an immediate decrease in tendon thickness in healthy young adults [3]. Based on in vitro evidence, it was proposed that the marked diametral strain response (≈ 20%) observed in vivo primarily reflected the radial extrusion of fluid from the tendon [4, 5]. Such convective fluid movement likely plays a vital role in tendon homeost...

A distributed remote collaborative hybrid test (RCHT) method for complex substructures based on OpenFresco is presented in this paper. Challenges the RCHT include modeling of numerical substructure, boundary degree-of-freedom (DOF) loading, and equivalent communication multi-story space frame as a substructure OpenFresco. The effectiveness accuracy proposed are verified by series tests that rep...

Fiber reinforced Polymers (FRP) have widely used for the purposes of enhances strength and ductility of concrete columns. Proper design of such hybrid columns, however, requires a better recognition of the behavior of concrete columns confined with FRP. In this paper, the influence of FRP thickness, concrete compressive strength, and column size on the performance of eccentrically loaded reacti...

BACKGROUND Systemic enzyme therapy may improve symptoms of exhaustive eccentric exercise due to anti-inflammatory properties. METHODS In a randomised, placebo-controlled, two-stage clinical trial, systemic enzyme therapy (Wobenzym) was administered for 72 hours before and 72 hours following a day on which subjects performed an exhaustive eccentric exercise (isokinetic loading of the quadricep...

PURPOSE To identify the effect of additional elastic force on the kinetic and kinematic characteristics, as well as the magnitude of leg stiffness, during the performance of accentuated countermovement jumps (CMJs). METHODS Fifteen trained male subjects performed 3 types of CMJ including free CMJ (FCMJ; ie, body weight), ACMJ-20, and ACMJ-30 (ie, accentuated eccentric CMJ with downward tensil...

  Background: The aim of this study was to investigate muscle damage indicators and electromyography activities of quadriceps muscles at 25° of hip flexion in untrained healthy females after an eccentric exercise induced muscle fiber damage.   Methods : A total of 14 healthy females participated in this pre-experimental study. The subjects performed maximal eccentric quadriceps contractions at ...

BACKGROUND Intratendinous Doppler activity has been interpreted as an equivalent of neovessels in the Achilles tendon and as a sign of tendinosis (AT). AIM To evaluate the vascular response as indicated by color Doppler activity after repeated loading of both symptomatic and non-symptomatic Achilles tendons. MATERIAL AND METHODS Ten non-trained, healthy subjects ran 5 km. Ultrasound (US) Do...

Identification of functional programmable mechanical stimulation (PMS) on tendon not only provides the insight of the tendon homeostasis under physical/pathological condition, but also guides a better engineering strategy for tendon regeneration. The aims of the study are to design a bioreactor system with PMS to mimic the in vivo loading conditions, and to define the impact of different cyclic...
