Introduction: Fatigue during voluntary muscle contractions is a complex and multifactorial phenomenon associated with central changes adaptations of the neuromuscular system. Objective: The purpose this study was to evaluate fatigue induced by intermittent successive extension knee between active inactive university students. Method: Twenty healthy men (≥18 years), voluntarily participated in study. To determine maximum isometric contraction (MVIC) extensors group, three sets were performed...
ABSTRACT Introduction: Although sodium bicarbonate (NaHCO3) supplementation has been shown to decrease fatigue and improve high-intensity exercise performance, the effects on maintenance of isometric contractions are not clear. Objective: To investigate effect NaHCO3 performance individuals subjected a protocol in an isokinetic dynamometer. Methods: Participants were 12 men randomized, double-blind, crossover, placebo-controlled trial. Sixteen minutes after intake 0.3 g/kg body mass or...
AIMS The aim of this study was to examine the effects 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 experimental protocol, each participant ingested 0,6 g.kg body mass-1 or placebo. Maximum voluntary isometric contraction tests were performed and after dynamic fatigue induction protocol...
Aim: To determine how EMG, anthropometric, and psychological factors, 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) inactive (I=10), performed 10x10:40secs maximal unilateral knee flexions extensions at 120o.s-1. The IPT, glucose, LDH, lactate concentrations perceptions pain, effort, recovery. Results: Active volunteers showed higher muscularity (52±5 vs 47±4...
ABSTRACT Introduction: Muscular fatigue during voluntary muscle contractions is a complex and multifactorial phenomenon associated with central changes adaptations of the neuromuscular system. Objective: The aim this study was to analyze in both peak torque hematological parameters active inactive healthy subjects following muscular protocol. Methods: Twenty-one adult males performed protocol (10 sets, 10 repetitions knee extension at 75% maximal isometric (MIT), 120º s-1 40 seconds rest)....
The aim of the present study was to determine whether ingestion sodium bicarbonate (NaHCO3) promotes changes in strength, muscle activity, and perceived exertion trained individuals following high-intensity intermittent exercise.Twelve men were enrolled a randomized, double-blind, crossover study.Each participant underwent two interventions with 14-day washout period: i) alkalosis (ALK) -administration gelatinous capsules containing 0.3 g.kg -1 NaHCO3; ii) placebo (PLA) calcium carbonate...
Sodium bicarbonate (NaHCO3) has been used as an ergogenic substance during high-intensity exercises. Therefore, the aim of present study was to investigate effects NaHCO3 supplementation on external and internal load parameters isokinetic exercise in trained subjects. Ten subjects were tested two occasions: after ingesting 0.3 g.kg-1 body mass or placebo. Maximum voluntary isometric contraction performed before a dynamic protocol consisting 10 series movements flexion/extension knee...
