1. Oxygen consumption and heart rate obtained in a ramp protocol are equivalent during exercise session of rectangular loading at ventilatory thresholds for athletes
Resumo O treinamento no limiar ventilatório (LV) é um estímulo adequado para melhorar os limiares em indivíduos sedentários, entretanto uma maior intensidade é necessária para indivíduos condicionados. A escolha do protocolo de teste de exercício cardiopulmonar (CPx) tem influência na identificação dos LV e pode reduzir sua confiabilidade na pres

2. Effects of continuous vs interval exercise training on oxygen uptake efficiency slope in patients with coronary artery disease
The oxygen uptake efficiency slope (OUES) is a submaximal index incorporating cardiovascular, peripheral, and pulmonary factors that determine the ventilatory response to exercise. The purpose of this study was to evaluate the effects of continuous exercise training and interval exercise training on the OUES in patients with coronary artery disease. Thirty-f

3. Determinação das zonas de transição metabólica durante a corrida mediante os limiares de variabilidade da frequência cardíaca / Determination of transition metabolic zones during running using hert rate variability thresholds
The aim of the present study was to obtain evidences of validity and reliability of the thresholds of heart rate variability (HRV). Nineteen male subjects, healthy and runners (30,4 ± 4,1 years; 175,9 ± 6,4 cm; 74,3 ± 8,5 kg) performed a progressive maximal test on a treadmill with initial velocity 5 km.h-1 e increases of 1 km.h-1 every 3 minutes (1% slop

4. Respostas cardiorrespiratórias, neuromuscularese e cinéticas de exercícios de hidroginástica / Cardiorespiratory, neuromuscular and kinetic responses of water aerobic exercises
The aim of the present study was to analyze the cardiorespiratory, neuromuscular and kinetic responses of women performing water aerobic exercises at different effort intensities. In study I, 20 young women (24.0 ± 2.5 years; 163.3 ± 6.7 cm; 60.0 ± 6.7 kg) performed four progressive test sessions, three corresponding to aquatic tests (stationary running (

5. Respostas cardiorrespiratórias máximas e submáximas de mulheres jovens na corrida em piscina funda / Maximal and submaximal cardiorespiratory responses to the deep water running in young women
A corrida em piscina funda é um exercício que simula a corrida em terra, realizada sem o apoio dos pés no fundo da piscina e com o auxílio de um colete flutuador. De acordo com as características específicas dessa atividade, é importante adequá-la aos objetivos dos praticantes, estudando as suas diferentes respostas cardiorrespiratórias. Deste modo,

6. Efeito do treinamento de musculação em circuito sobre a aptidão cardiorrespiratória e citocinas plasmáticas IL-6, IL-8, IL-10, TNF, IL-1β e IL-12p70 em mulheres saudáveis / Efeito do treinamento de musculação em circuito sobre a aptidão cardiorrespiratória e citocinas plasmáticas IL-6, IL-8, IL-10, TNF, IL-1β e IL-12p70 em mulheres saudáveis
There are evidences demonstrating that long-term aerobic exercises boost the plasmatic cytokines concentrations. However, there are few researches that deal with that relation in short-term and high intensity ones. This study aims at verifying the effects of strength training in circuit over the cardiorespiratory competence response and also over the plasmat

7. A variação da acuidade visual durante esforços fisicos em atletas com baixa visão
This research work evaluated the response of the visual acuity in visually impaired athletes during a procedure of continued physical exercise. The evaluation was carried out in two days of testing. The subjects were six visually impaired, high performance runners athletes. The following were carried out during the first day: medical examination, anamnesis a

8. The ventilatory response to CO2 of the peripheral and central chemoreflex loop before and after sustained hypoxia in man.
1. The ventilatory response to sustained hypoxia is characterized by a fast increase due to the peripheral chemoreceptors followed by a slow decline. The mechanism of this decline is unknown. 2. To investigate the characteristics of the ventilatory response to sustained hypoxia ten healthy subjects were exposed to two consecutive periods of isocapnic hypoxia

9. Effect of theophylline on exercise performance in patients with severe chronic obstructive pulmonary disease.
BACKGROUND--Theophylline is a well known bronchodilator which has been used for more than 50 years in the treatment of obstructive pulmonary diseases. In patients with severe chronic obstructive pulmonary disease whose cardiopulmonary performance is limited by their ventilatory capacity the administration of theophylline may improve exercise performance.
