1. 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

2. Medo de quedas e força muscular do quadril em idosos independentes da comunidade
RESUMO O medo de quedas pode fazer com que o idoso desenvolva estratégias que alteram o equilíbrio semiestático e dinâmico, predispondo-o a um risco aumentado de cair. A função muscular dos abdutores e adutores de quadril tem importante papel na manutenção da estabilidade postural. Entretanto, não se sabe se idosos com medo de cair apresentam maior

3. 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

4. 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

5. 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

6. Decreased muscle strength is associated with proinflammatory cytokines but not testosterone levels in men with diabetes
The aim of this study was to compare muscle strength in male subjects with type 2 diabetes mellitus (DM2) with and without low plasma testosterone levels and assess the relationship between muscle strength, testosterone levels, and proinflammatory cytokines. Males (75) aged between 18 and 65 years were divided into 3 groups: control group that did not have d

7. 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

8. Skinfold thickness affects the isometric knee extension torque evoked by Neuromuscular Electrical Stimulation
BACKGROUND: Subcutaneous adipose tissue may influence the transmission of electrical stimuli through to the skin, thus affecting both evoked torque and comfort perception associated with neuromuscular electrical stimulation (NMES). This could seriously affect the effectiveness of NMES for either rehabilitation or sports purposes. OBJECTIVE: To investigat

9. Effect of L-carnitine on exercise performance in patients with mitochondrial myopathy
Exercise intolerance due to impaired oxidative metabolism is a prominent symptom in patients with mitochondrial myopathy (MM), but it is still uncertain whether L-carnitine supplementation is beneficial for patients with MM. The aim of our study was to investigate the effects of L-carnitine on exercise performance in MM. Twelve MM subjects (mean age±SD=35.4

10. The influence of stimulus phase duration on discomfort and electrically induced torque of quadriceps femoris
BACKGROUND: Although a number of studies have compared the influence of different electrical pulse parameters on maximum electrically induced torque (MEIT) and discomfort, the role of phase duration has been poorly investigated. OBJECTIVE: To examine the variation in muscle torque and discomfort produced when electrically stimulating quadriceps femori

11. Strength deficit of knee flexors is dependent on hip position in adults with chronic hemiparesis
BACKGROUND: The extent to which muscle length affects force production in paretic lower limb muscles after stroke in comparison to controls has not been established. OBJECTIVES: To investigate knee flexor strength deficits dependent on hip joint position in adults with hemiparesis and compare with healthy controls. METHOD: a cross-sectional study with ten su

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
