1. L-ARGININE SUPPLEMENTATION IMPROVES POST-EXERCISE HYPOTENSION IN ELDERLY WOMEN
RESUMO Introdução: A suplementação de L-arginina aumenta os níveis plasmáticos dos metabólitos de óxido nítrico, um importante mediador da dilatação periférica. Dessa forma, é possível que a suplementação de L-arginina maximize a duração e a magnitude dos efeitos hipotensores pós-exercício. Objetivos: O presente estudo investigou os efe

2. 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

3. Multivariate linear regression analysis to evaluate multiple-set performance in active and inactive individuals
Abstract Aim: To determine how EMG, anthropometric, and psychological factors, and physical activity levels affect isokinetic peak torque performance (IPT) of multiple set exercise sessions. Methods: 20 participants (27±7 years old), classified as active (A=10) and inactive (I=10), performed 10x10:40secs of maximal unilateral knee flexions and extension

4. 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

5. Use of combined method, accelerometer and international physical activity questionnaire, to determinate occurence of physical inactivity in adults
Abstract Aim Evaluate and compare the proportion of PI and associated factors by IPAQ questionnaire, triaxial accelerometry and the combination of both. Adults aged ( 18 years were enrolled (n = 250). Methods We considered PI as < 600 MET-min/wk in the IPAQ total score, < 150 min/wk of moderate-to-vigorous physical activity in 7 days accelerometry, and the

6. Effects of a progressive resistance exercise program with high-speed component on the physical function of older women with sarcopenic obesity: a randomized controlled trial
ABSTRACT Background Sarcopenic obesity is associated with disability in older people, especially in women. Resistance exercises are recommended for this population, but their efficacy is not clear. Objective To evaluate the effects of a progressive resistance exercise program with high-speed component on the physical function of older women with sarcopenic

7. 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

8. Study of muscle fatigue in isokinetic exercise with estimated conduction velocity and traditional electromyographic indicators
INTRODUCTION: In the study of human biomechanics, it is often desirable to evaluate fatigue in the muscles that are involved in performing a particular task. Identifying the phenomena responsible for this condition is a problem that in most cases is complex and requires appropriate research mechanisms. Isokinetic dynamometry (ID) and surface electromyography

9. Differences in muscle strength after ACL reconstruction do not influence cardiorespiratory responses to isometabolic exercise
Objectives: To investigate whether the muscle strength decrease that follows anterior cruciate ligament (ACL) reconstruction would lead to different cardiorespiratory adjustments during dynamic exercise. Method: Eighteen active male subjects were submitted to isokinetic evaluation of knee flexor and extensor muscles four months after ACL surgery. Thigh c

10. Relationship between work rate and oxygen uptake in mitochondrial myopathy during ramp-incremental exercise
We determined the response characteristics and functional correlates of the dynamic relationship between the rate (Δ) of oxygen consumption ( O2) and the applied power output (work rate = WR) during ramp-incremental exercise in patients with mitochondrial myopathy (MM). Fo

11. Efeitos de um treinamento físico sobre o equilíbrio estático e dinâmico de mulheres idosas residentes na área de abrangência do Programa Saúde da Família de São Carlos
IBGE estimative for relative Brazilian elderly participation was 9.49% in 2008 and 29.75% in 2050. However, the country has been organized to define public policy to elderly people. Health Family Program has been presented as a strategy to consolidate this policy. Physical therapy participates of this system with a different perspective. It is also performin

12. Postural control in elderly submitted to multi-sensory versus strength exercises: a randomized single-blind study / Controle postural em idosos submetidos a treinamento resistido versus exercícios multissensoriais: um estudo aleatorizado e simples-cego
The practice of regular exercise in aging is helpful to bring benefits in all aspects older peoples life, especially on senescence individuals postural control that tend to reduce such capacity. The aim of this study was to verify and to analyze the changes promoted by two types of exercise programs on postural control in healthy elderly. The study design wa
