2. Effect of an experimental fatigue protocol applied to the quadriceps femoris muscle of physically active persons
Abstract Aims: The purpose of this study was to test an experimental fatigue protocol for the knee joint extensor muscles performed on an isokinetic dynamometer. Method: SPIRIT recommendations were applied. Participants were 40 healthy, young men and women. Protocol: The pre-fatigue quadriceps femoris peak torque during concentric maximum voluntary contra

3. Essential oil of the leaves of Eugenia sulcata preserve myocardial contractility and does not present immunotoxicity
The essential oil of the leaves of Eugenia sulcata, in the Myrtaceae family, has a demonstrated antihypertensive effect, but its effects on heart muscle and its toxicity have not yet been elucidated. Little chemical or biological data are available for E. sulcata, whether emphasizing the beneficial effects or the pharmacological security of this species. Thi

4. Quadriceps muscle weakness influences the gait pattern in women with knee osteoarthritis
Abstract Background: Osteoarthritis is the most prevalent rheumatic disease in the population and is characterized by limitation of main functional activities of daily living, as the gait. Muscle strength is a variable that may be related to performance in daily tasks. Therefore, we to analyze the gait pattern in individuals with knee osteoarthritis (KOA) a

5. EFEITO AGUDO DA APLICAÇÃO DE VIBRAÇÃO DE CORPO INTEIRO NA FORÇA MUSCULAR DE MEMBROS SUPERIORES
RESUMO O objetivo desse estudo foi verificar o efeito agudo da aplicação de vibração de corpo inteiro (VCI) sobre o impulso e sobre a força máxima de membros superiores. Vinte voluntários do sexo masculino, treinados, com idade: 23,8 ± 3,3 anos, foram submetidos a 3 sessões (uma sessão de familiarização e duas sessões de intervenção). Em cada

7. SODIUM BICARBONATE SUPPLEMENTATION IMPROVES PERFORMANCE IN ISOMETRIC FATIGUE PROTOCOL
RESUMO Introdução: A suplementação de bicarbonato de sódio (NaHCO3) tem demonstrado atenuar a fadiga e melhorar o desempenho do exercício de alta intensidade, mas os efeitos sobre a manutenção de contrações isométricas são pouco claros. Objetivo: Investigar o efeito do NaHCO3 no desempenho de indivíduos submetidos ao protocolo de fadiga em exe

8. 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

9. Low-intensity laser therapy improves tetanic contractions in mouse anterior tibialis muscle injected with Bothrops jararaca snake venom
Abstract Introduction Envenomation by Bothrops snakes can produce local pain, edema, hemorrhage and myonecrosis. However, standard antivenom therapy is generally ineffective in neutralizing these effects so that alternative methods of treatment have been investigated. In experimental animals, low-level laser therapy (LLLT) attenuates the local effects of Bo

10. Influence of obstructive sleep apnea syndrome in the fluctuation of the submaximal isometric torque of knee extensors in patients with early-grade osteoarthritis
OBJECTIVE: The aim of this study was to investigate whether obstructive sleep apnea (OSA) alters the fluctuation of submaximal isometric torque of the knee extensors in patients with early-grade osteoarthritis (OA).METHOD: The study included 60 male volunteers, aged 40 to 70 years, divided into four groups: Group 1 (G1) - Control (n=15): without OA and witho

12. Effect of low-level laser therapy (GaAlAs - λ660 nm) on muscle function
Introduction:Low-level laser therapy (LLLT) is effective in preventing fatigue and in stimulating the microcirculation and cellular activity. In this study, we examined the effect of LLLT on injured tibial muscle in vivo by assessing muscle function during fatigue.MethodsTwenty-four male mice were used. Each mouse received an injection of sterile 0.9% saline
