1. Comparison between Bruce and Ramp Protocols for Exercise Testing in the Diagnosis of Myocardial Ischemia
Abstract Background: Exercise tests are an important tool in the investigation of myocardial ischemia. The ramp protocol has gained increasing importance in clinical practice because of the possibility of individualizing its exercise intensity. Objective: To assess and compare the sensitivity, specificity, and accuracy of Bruce and ramp protocols for exerc

2. Limited cardiopulmonary capacity in patients with liver cirrhosis when compared to healthy subjects
SUMMARY OBJECTIVES: The present study compared cardiorespiratory capacity between cirrhotic patients and healthy subjects. METHODS: Nineteen cirrhotic patients and 19 healthy subjects, paired by age and gender, participated in the study. Volunteers performed an incremental cardiopulmonary test with a ramp protocol, a ventilatory and metabolic variables wer

3. 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

4. The association between physical activity, sedentary behavior and the occurrence of falls in asymptomatic adults over 40 years old
Resumo Introdução: O Comportamento sedentário (CS) tem sido descrito como fator de risco independente para saúde, a despeito da recomendação de atividade física moderada a intensa (AFMI). Contudo, pouco foi investigado se CS e AFMI são preditores da ocorrência de quedas. Objetivo: Comparar as associações entre CS e AFMI e a ocorrência de qued

5. Use of cardiopulmonary exercise testing to assess early ventilatory changes related to occupational particulate matter
Spirometry has been used as the main strategy for assessing ventilatory changes related to occupational exposure to particulate matter (OEPM). However, in some cases, as one of its limitations, it may not be sensitive enough to show abnormalities before extensive damage, as seen in restrictive lung diseases. Therefore, we hypothesized that cardiopulmonary ex

6. Heart rate as an indicator for exercise prescription for normal, overweight, and obese adolescents
Abstract This study aimed to investigate the relationship between heart rate (HR) predicted and VO2max using a CPET (cardiopulmonary exercise testing) among normal weight, overweight, and obese adolescents. The sample comprised 299 adolescents (142 boys), from Vitória (ES, Brazil), aged 10-14 years (12.6±1.4). Adolescents were classified into normal weight

7. Use of the Wasserman equation in optimization of the duration of the power ramp in a cardiopulmonary exercise test: a study of Brazilian men
This study aimed to analyze the agreement between measurements of unloaded oxygen uptake and peak oxygen uptake based on equations proposed by Wasserman and on real measurements directly obtained with the ergospirometry system. We performed an incremental cardiopulmonary exercise test (CPET), which was applied to two groups of sedentary male subjects: one ap

8. Intensity and physiological responses to the 6-minute walk test in middle-aged and older adults: a comparison with cardiopulmonary exercise testing
The 6-minute walk test (6MWT) is a simple field test that is widely used in clinical settings to assess functional exercise capacity. However, studies with healthy subjects are scarce. We hypothesized that the 6MWT might be useful to assess exercise capacity in healthy subjects. The purpose of this study was to evaluate 6MWT intensity in middle-aged and olde

9. Variabilidade da frequência cardíaca após treinamento concorrente : comparação entre homens e mulheres de meia-idade = Heart rate variability after concurrent training : comparison between middle-aged men and women / Heart rate variability after concurrent training : comparison between middle-aged men and women
The autonomic nervous system dysfunction and the increase in chronic degenerative diseases are manifested by the aging process, leading to changes of the autonomic modulation cardiac, and therefore the heart rate variability. Regarding the response of the autonomic nervous system and cardiorespiratory adaptive responses are even less enlightening evidencing

10. Different ventilatory responses to progressive maximal exercise test performed with either the arms or legs
OBJECTIVE: This study aimed to compare respiratory responses, focusing on the time-domain variability of ventilatory components during progressive cardiopulmonary exercise tests performed on cycle or arm ergometers. METHODS: The cardiopulmonary exercise tests were conducted on twelve healthy volunteers on either a cycle ergometer or an arm ergometer followin

11. Long-term stability of the oxygen pulse curve during maximal exercise
INTRODUCTION: Exercise oxygen pulse (O2 pulse), a surrogate for stroke volume and arteriovenous oxygen difference, has emerged as an important variable obtained during cardiopulmonary exercise testing. OBJECTIVES: We hypothesized that the O2 pulse curve pattern response to a maximal cycling ramp protocol exhibits a stable linear pattern in subjects reevaluat

12. The decreased oxygen uptake during progressive exercise in ischemia-induced heart failure is due to reduced cardiac output rate
We tested the hypothesis that the inability to increase cardiac output during exercise would explain the decreased rate of oxygen uptake (VO2) in recent onset, ischemia-induced heart failure rats. Nine normal control rats and 6 rats with ischemic heart failure were studied. Myocardial infarction was induced by coronary ligation. VO2 was measured during a ram
