1. THE EFFECT OF MUSCLE DAMAGE AND THE IL-6-174C/G POLYMORPHISM ON THE SERUM IL-6 LEVELS OF OLDER MEN
RESUMO Introdução O rápido envelhecimento populacional é uma realidade global. O principal desafio atual é promover o envelhecimento saudável de cada vez mais pessoas, atuando em fatores que podem ser modificados, como por exemplo, o exercício físico. O exercício regular pode contribuir com a prevenção de doenças crônicas associadas ao envelhec

2. Specific interventions for prevention of muscle injury in lower limbs: systematic review and meta-analysis
Resumo Introdução: Lesões musculares apresentam incidência associada à alongamento extremo, ou ainda, a uma contração excêntrica de alta intensidade. Tais lesões, acarretam prejuízos graves aos atletas que incluem queda de rendimento, afastamento e transtornos psicológicos. Neste cenário, o estudo de métodos preventivos eficazes, constituem fa

3. Effects of previous carbohydrate supplementation on muscular fatigue: double-blind, randomized, placebo-controlled crossover study
Abstract AIMS The aim of this study was to examine the effects of previous carbohydrate supplementation on high-volume resistance exercise performance METHODS Twenty males physically independent adults aged ≥18 years participated in a double-blind randomized placebo-controlled crossover study. Sixty minutes before the experimental protocol, each particip

4. Effects of eccentric exercise in pressure pain threshold in subjects with functional ankle equinus condition
RESUMO Exercícios de alongamento são amplamente utilizados pela população antes da atividade esportiva. Uma das técnicas mais comuns é o exercício excêntrico. Aqui, fizemos um exame clínico de 98 indivíduos com condição de pé equino antes da atividade e após 30 minutos de corrida (49 corredores com exercício excêntrico anterior e 49 sem exerc

5. Time to task failure of the contralateral untrained limb after high load-low repetition eccentric and low load-high repetition resistance training
Abstract Aims: Cross-training is the process whereby training of one limb gives rise to enhancements in the performance of the opposite, untrained limb and may be dependent on type of muscle contractions performed. The aim of this study was to investigate whether unilateral resistance training using eccentric contraction is more effective than concentric res

6. Longer repetition duration increases muscle activation and blood lactate response in matched resistance training protocols
Abstract This study analyzed the effect of different repetition durations on electromyographic and blood lactate responses of the bench press exercise. Fifteen recreationally trained male volunteers completed two training protocols, matched for intensity (% one-repetition maximum; 1RM), number of sets, number of repetitions, and rest intervals. One of the pr

7. A single bout of exercise with a flexible pole induces significant cardiac autonomic responses in healthy men
OBJECTIVES: Flexible poles can provide rapid eccentric and concentric muscle contractions. Muscle vibration is associated with a "tonic vibration reflex” that is stimulated by a sequence of rapid muscle stretching, activation of the muscle spindles and stimulation of a response that is similar to the myotatic reflex. Literature studies analyzing the acute

8. Efeitos do uso da corrente interferencial no tratamento da dor decorrente de microlesão induzida por exercício excêntrico nos músculos flexores e extensores do joelho em humanos
O objetivo do presente trabalho foi avaliar os efeitos da corrente interferencial na sensibilidade dolorosa e no torque muscular dos músculos flexores e extensores do joelho após a realização de um protocolo de exercícios excêntricos. A amostra foi constituída de 41 indivíduos saudáveis do sexo masculino com idade entre 18 e 33 anos, que foram divid

9. Fibrose muscular em camundongo mdx : efeitos do exercício físico e de agente anti-fibrótico / : Prevention of muscle fibrosis and myonecrosis in mdx mice by suramin, a TGF-beta1 blocker
The mdx mouse is commonly used as a model to study Duchenne muscular dystrophy (DMD) however shows cycles of muscle regeneration and reduced fibrosis. The purposes of this study were (1) to induce muscle fibrosis through eccentric running exercise in mdx mice and (2) to verify the effects of suramin on muscle fibrosis. Six-month-old mdx (n=42) and control (C

10. Functional and morphological effects of resistance exercise on disuse-induced skeletal muscle atrophy
Abstract The reduction of skeletal muscle loss in pathological states, such as muscle disuse, has considerable effects in terms of rehabilitation and quality of life. Since there is no currently effective and safe treatment available for skeletal muscle atrophy, the search for new alternatives is necessary. Resistance exercise (RE) seems to be an important t

11. Eccentric and concentric cardiac hypertrophy induced by exercise training: microRNAs and molecular determinants
Among the molecular, biochemical and cellular processes that orchestrate the development of the different phenotypes of cardiac hypertrophy in response to physiological stimuli or pathological insults, the specific contribution of exercise training has recently become appreciated. Physiological cardiac hypertrophy involves complex cardiac remodeling that occ

12. Low-frequency fatigue at maximal and submaximal muscle contractions
Skeletal muscle force production following repetitive contractions is preferentially reduced when muscle is evaluated with lowfrequency stimulation. This selective impairment in force generation is called low-frequency fatigue (LFF) and could be dependent on the contraction type. The purpose of this study was to compare LFF after concentric and eccentric max
