Despite full voluntary effort, neuromuscular activation of the quadriceps femoris muscle appears inhibited during slow concentric and eccentric contractions. Our aim was to compare neuromuscular activation during maximal voluntary concentric and eccentric quadriceps contractions, hypothesizing that inhibition of neuromuscular activation diminishes with resistance training. In 15 men, pretrainin...

This study compares the changes in pathway and center of gravity (COG) on the calcaneus of non-involved and involved sides according to eccentric and concentric strengthening in patients with unilateral Achilles tendinopathy. The goal was to define the biomechanical changes according to eccentric strengthening for the development of clinical guidelines. Eighteen patients with Achilles tendinopa...

The aim of this study was to evaluate the alterations in eccentric evertor/concentric invertor strength ratio and their importance in the chronically unstable ankle. Eight patients with chronic ankle instability (CAI) and nine healthy individuals participated in this study. Isokinetic concentric and eccentric invertor and evertor muscle strength measurement was carried out at an angular velocit...

OBJECTIVE To analyze concentric and eccentric strength and endurance in patients with unilateral intermittent claudication. INTRODUCTION Basic motor tasks are composed of concentric, isometric, and eccentric actions, which are related and contribute to physical performance. In previous studies of patients with intermittent claudication, the disease-related reduction in concentric and isometri...

BACKGROUND/AIMS Both all-cause and cardiovascular mortality risks are extremely high in patients with end-stage kidney disease (ESKD). Sudden death accounts for approximately one-quarter of all fatal events. Left ventricular hypertrophy (LVH) is a known risk factor for mortality and can be divided in 2 types: concentric and eccentric. This study evaluated possible differences in all-cause morta...

BACKGROUND Localized exercises are widely used in rehabilitation processes. The predominant options are exercises with an emphasis on either concentric or eccentric contractions. Eccentric exercises promote greater strength gains compared to classical concentric stimuli, but can cause muscle damage. The aim of present study was to compare strength training composed of 10 sessions with progressi...

Baptista R, Onzi E, Goulart N, Dos Santos LD, Makarewicz G, Vaz M. Effects of Concentric Versus Eccentric Strength Training on the Elderly’s Knee Extensor Structure and Function. JEPonline 2016;19(3):120-132. The purpose of this study was to compare the effects of eccentric vs. concentric 12-wk strength training program on the quadriceps properties of elderly men. Twenty-three subjects performe...

This study investigated the chronology of neural and morphological adaptations to knee extensor eccentric training and their contribution to strength gains in isometric, concentric and eccentric muscle actions. 20 male healthy subjects performed a 12-week eccentric training program on an isokinetic dynamometer, and neuromuscular evaluations of knee extensors were performed every 4 weeks. After ...

BACKGROUND The different geometric patterns of the left ventricle may or may not coexist with chamber dilatation. The prognostic impact of such a combination is unclear. METHODS AND RESULTS We studied a cohort of 2635 initially untreated patients with hypertension, mean age 50 years. At entry, 24-hour ambulatory blood pressure progressively increased across the patterns of normal geometry, co...

The aim of this systematic review was to determine if eccentric exercise is superior to concentric exercise in stimulating gains in muscle strength and mass. Meta-analyses were performed for comparisons between eccentric and concentric training as means to improve muscle strength and mass. In order to determine the importance of different parameters of training, subgroup analyses of intensity o...
