1. 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

2. Energy system contribution in a maximal incremental test: correlations with pacing and overall performance in a 10-km running trial
This study aimed to verify the association between the contribution of energy systems during an incremental exercise test (IET), pacing, and performance during a 10-km running time trial. Thirteen male recreational runners completed an incremental exercise test on a treadmill to determine the respiratory compensation point (RCP), maximal oxygen uptake (V˙O2

3. Association between muscle strength and the cardiopulmonary status of individuals living with HIV/AIDS
OBJECTIVE: The purpose of this study was to compare aerobic function [anaerobic threshold (%VO2-AT), respiratory compensation point (%VO2-RCP) and peak oxygen uptake (VO2peak)] between physically active patients with HIV/AIDS and matched controls and to examine associations between disease status, poor muscle strength, depression (as estimated by the profile

4. Effect of continuous and interval exercise training on the PETCO2 response during a graded exercise test in patients with coronary artery disease
OBJECTIVE: The purpose of this study was to evaluate the following: 1) the effects of continuous exercise training and interval exercise training on the end-tidal carbon dioxide pressure (PETCO2) response during a graded exercise test in patients with coronary artery disease; and 2) the effects of exercise training modalities on the association between PETCO

5. The Borg scale as a tool for self-monitoring and self-regulation of the exercise effort in patients with heart failure in hydrotherapy and land: a randomized, blinded, controlled trial / A escala de Borg como ferramenta de auto-monitorização e auto-adaptação do esforço em pacientes com insuficiência cardíaca na hidroterapia e no solo: estudo randomizado, cego e controlado
BACKGROUND: The Borg scale is the standardization of perceived exertion most widespread and has been proposed to ensure a submaximal effort in patients with the syndrome of heart failure (SIC). Hydrotherapy is a new method used in cardiovascular rehabilitation programs that seems to offer the patient an extra benefit compared to conventional exercise trainin

6. Correlação entre o ponto de compensação respiratoria e desempenho em corredores de rua / Correlation between respiratory compensation point and performance in runners
O consumo máximo de oxigênio (VO2max) é considerado medida padrão de potência aeróbica e desempenho físico, por integrar os sistemas nervoso, cardiopulmonar e metabólico e foi considerado fator determinante para o desempenho de corredores devido as boas correlações encontradas em corridas de 10 a 90 km. Além dele, parâmetros submáximos relaciona

7. Efeitos agudos do exercício cardiovascular sobre os níveis serotoninérgicos e perfil antropométrico e psicométrico de idosas ativas
Purposes: 1) Identify volunteers anthropometric (AS) and psychometric (PS) status and, 2) verify the dose-response effects of cardiovascular physical exercise of different intensities and duration, on the peripheral alterations of the serotoninergic system, through serotonin (5-HT) and tryptophan (TRP) concentrations and the possible central alterations, thr

8. C4 Acid Metabolism and Dark CO2 Fixation in a Submersed Aquatic Macrophyte (Hydrilla verticillata) 1
The CO2 compensation point of the submersed aquatic macrophyte Hydrilla verticillata varied from high (above 50 microliters per liter) to low (10 to 25 microliters per liter) values, depending on the growth conditions. Plants from the lake in winter or after incubation in an 11 C/9-hour photoperiod had high values, whereas summer plants or those incubated in

9. Responses of Two CAM Species to Different Irradiances during Growth and Susceptibility to Photoinhibition by High Light 1
Two CAM species, Kalanchoë daigremontiana Hamet et Perrier and Hoya carnosa (L.) R. Br., were grown under a range of five photon flux area densitites (PFD) and then characterized. Significant acclimation to shade was indicated by progressive decreases in leaf thickness, rates of respiratory O2 uptake, light compensation point, maximum rates of photosyntheti

10. Mechanism of Plant Growth Stimulation by Naphthenic Acid: II. Enzymes of CO2 Fixation, CO2 Compensation Point, Bean Embryo Respiration 1
Potassium naphthenate, 20 mm, was applied to the foliage of 14-day-old plants of bush bean, Phaseolus vulgaris L, cv Top Crop, maize, Zea mays L, cv Golden Bantam, spring wheat, Triticum vulgare Vill., cv Neepawa, and a 2 mm solution to 21-day-old plants of sugar beet, Beta vulgaris L, cv CS-43. Seven days after application, the activities of ribulose diphos
