13. Exercise training and detraining modify the morphological and mechanical properties of single cardiac myocytes obtained from spontaneously hypertensive rats
We determined the effects of exercise training and detraining on the morphological and mechanical properties of left ventricular myocytes in 4-month-old spontaneously hypertensive rats (SHR) randomly divided into the following groups: sedentary for 8 weeks (SED-8), sedentary for 12 weeks (SED-12), treadmill-running trained for 8 weeks (TRA, 16 m/min, 60 min/

14. Efeito da fototerapia prévia ao exercício isocinético sobre a fadiga e o dano muscular
Desde seu desenvolvimento na década de 60, a fototerapia têm sido utilizada no tratamento de diversas condições patológicas, havendo um considerável corpo de evidências acerca de sua ação regenerativa, analgésica e anti-inflamatória. Tais efeitos terapêuticos podem ser explicados pela capacidade que a energia luminosa possui de ser absorvida pelo

15. Efeito agudo de diferentes velocidades de exercício excêntrico na sinalização da hipertrofia muscular / Effect of an acute bout of eccentric exercise at Different velocities on muscle hypertrophy signaling
Atualmente, alguns pesquisadores tem se dedicado ao estudo do efeito da manipulação do treinamento de força sobre a ativação das vias de sinalização intracelular para hipertrofia. Tem-se sugerido que o grau de tensão muscular desempenhe um papel importante nesta sinalização. Dentre os diferentes tipos de ações musculares, as ações excêntricas

16. Low-frequency fatigue at maximal and submaximal muscle contractions
Skeletal muscle force production following repetitive contractions is preferentially reduced when muscle is evaluated with low-frequency 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 ma

17. Efeitos da suplementação de taurina sobre os parâmetros de estresse oxidativo muscular induzidos por exercício excêntrico / Efeitos da suplementação de taurina sobre os parâmetros de estresse oxidativo muscular induzidos por exercício excêntrico / Taurine supplementation effects on muscle oxidative stress induced by eccentric exercise / Taurine supplementation effects on muscle oxidative stress induced by eccentric exercise
This study was to investigate the effects of taurine supplementation on biomarkers of oxidative stress after eccentric exercise. Twenty four male rats Wistar were divided into the following groups (n=6): control (C); eccentric exercise (EE); eccentric exercise plus taurine (EET); eccentric exercise plus saline (EES). Taurine was administered with solution of

18. Dano muscular induzido pelo sistema de treinamento de cargas descendentes em exercício resistido / Muscle damage induced by drop set training system in resistance exercise
INTRODUCTION: Exercise-induced muscle damage (EIMD) in humans occurs after unaccustomed or vigorous exercise. Various experimental models was dedicated to EIMD, however few studies, essential those with eccentric action, replicated action that commonly occur during real physical training. PURPOSE: The general purpose of this research was to verify and to com

19. Analysis of adaptive muscular responses to stretching and eccentric exercises applied after immobilization of the hindlimb in female rats in postnatal development / Análise das respostas musculares adaptativas frente a protocolos de alongamento e exercício excêntrico, aplicados após desuso do membro posterior de ratas em desenvolvimento pós-natal
O presente estudo analisou as mudanças e adaptações geradas pelos protocolos de alongamento e exercício excêntrico nos músculos sóleo e plantar, após 10 dias de imobilização do membro posterior de ratas em desenvolvimento pós-natal. Para isso, 45 ratas da raça Wistar, com 21 dias de idade, foram divididas em 10 grupos: grupo imobilizado (GI); gru

20. Muscular responses to eccentric action performed at different velocities and its influence in the repeated bout effect / Respostas musculares à realização de ações excêntricas em diferentes velocidades e sua influência no efeito da carga repetida
Performing a bout of eccentric exercise causes muscle damage. During recovery, some adaptations occur that can protect muscle structure. These adaptations are known as Repeated Bout Effect. However, this phenomenon has been studied with two bouts. Velocity of eccentric action has been referred as one possible factor which can affect the extension of muscle d

21. Efeito agudo e crônico do exercício resistido de alta intensidade sobre o torque, atividade eletromiográfica do vasto lateral e freqüência cardíaca de homens idosos.
The objective of this study was to investigate the acute and chronic effects of high intensity resistance physical exercise on the magnitude of maximal average torque response normalized by body mass (MAT), RMS amplitude of eletromyographic signals (EMGs) of the vastus lateralis and heart rate variation (∆HR). Subjects were nine non-smoking men (ages 6

22. Contribuição das forças musculares isocinéticas de joelho e tronco para aquisição da massa óssea em atletas de futebol feminino / Contributions of knee and trunk isokinetic muscular strength to bone mass acquisition in female soccer players
OBJECTIVE: to analyze the contribution of isokinetic muscular strength of dominant knee and trunk flexors and extensors in the acquisition of bone mass in the correspondent regions that these forces are applied in female soccer players. METHODS: twenty-two female soccer athletes (GAF) were compared with 20 matched-controls (GC). The bone mineral content (BMC

23. Efeitos agudos do exercÃcio resistido sobre linfÃcitos totais, CD4 e CD8 de idosas
Introduction - Physical exercise has been recommended to minimize the effects of the aging process and resistance training has been recognized as a type of exercise efficient in increase muscle strength and mass of older individuals. On the other hand, high intensity exercise is associated with a higher incidence of illness in athletes, particularly those of

24. Alterações funcionais e morfológicas do músculo quadríceps induzidas pelo treinamento excêntrico após reconstrução do LCA.
The anterior cruciate ligament (ACL) is the most commonly injured ligament in the knee and its rupture results in pain, instability, muscle atrophy and weakness. The quadriceps femoris muscle dysfunction is common before and after ACL reconstruction and can persist over years. A detailed understanding of neuromuscular function after ACL reconstruction is cri
