1. 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

2. 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

3. Does the incremental shuttle walk test require maximal effort in young obese women?
Obesity is a chronic disease with a multifaceted treatment approach that includes nutritional counseling, structured exercise training, and increased daily physical activity. Increased body mass elicits higher cardiovascular, ventilatory and metabolic demands to varying degrees during exercise. With functional capacity assessment, this variability can be eva

4. Determination of anaerobic threshold through heart rate and near infrared spectroscopy in elderly healthy men
BACKGROUND: Aging leads to low functional capacity and this can be reversed by safe and adequate exercise prescription. OBJECTIVE: The aim of this study was to identify the anaerobic threshold (AT) obtained from the V-slope method as well as visual inspection of oxyhemoglobin ( O2Hb) and deoxyhemoglobin (HHb) curves and compare findings with the heter

5. Functional status and dyspnea as performance of activities of daily living after physical and inspiratory muscle training in patients with chronic obstructive pulmonary disease
Background: Exercise training improves exercise capacity, the performance of activities of daily living, decreases dyspnea, and enhances the inspiratory muscle strength in patients with COPD. Less is known on ventilatory and metabolic responses ( E, O2) during the execution activities of daily life (ADL) in patients going through physical training with addit

6. 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

7. Reprodutibilidade do teste do degrau incremental em pacientes com doença pulmonar obstrutiva crônica. / Reprodutibilidade of the test of the incremental step in patients with pulmonary illness obstrutiva chronicle
The determination of the functional capacity has been considered an important part of assessment in patients with chronic obstructive pulmonary disease (COPD), especially by using testes which are representatives of daily activities. Besides these characteristics the step test is considered a portable test and requires low costs. The objective of this study

8. Relationship of BODE Index to functional tests in chronic obstructive pulmonary disease
OBJECTIVE: To determine if there is a correlation between the BODE Index and variables assessed during the Activities of Daily Living assessment, performance on lower limber tests, and peripheral muscle impairment of the upper limb in patients with chronic obstructive pulmonary disease. MATERIALS AND METHODS: Ten men (aged 58 to 80 years old) with moderate t

9. Avaliação muscular e capacidade de exercício em pacientes com doença pulmonar obstrutiva crônica leve/moderado com normoxemia ou hipoxemia leve diurna e dessaturação noturna sem síndrome da apnéia obstrutiva do sono
We carried out a transversal study which included 21 patients with mild/moderate COPD, divided into a nocturnal dessaturator and a nocturnal non-dessaturator group without OSA. We first studied the total sample, to characterize its respiratory functional components, sleep and exercise. We analyzed the pulmonary function, polissonography variables, peripheral

10. Comparison of anaerobic threshold determined by visual and mathematical methods in healthy women
Several methods are used to estimate anaerobic threshold (AT) during exercise. The aim of the present study was to compare AT obtained by a graphic visual method for the estimate of ventilatory and metabolic variables (gold standard), to a bi-segmental linear regression mathematical model of Hinkley's algorithm applied to heart rate (HR) and carbon dioxide o

11. Influência do alongamento da cadeia muscular respiratória na postura rã do método de reeducação postural global (RPG) sobre as respostas cardiorrespiratórias.
O alongamento pelo método de reeducação postural global (RPG) tem sido muito utilizado como conduta fisioterapêutica em alterações posturais, porém, sua ação sobre o sistema cardiorrespiratório é pouco documentada. No entanto, as evidências científicas são necessárias para sua validação como alternativa de tratamento. Dentro desse contexto,

12. Efects of Physical Training asthsmatic women. / Efeitos de um programa de treinamento físico em mulheres asmáticas.
The aim of this study was to evaluate the effects of the lower and upper limb physical training (LLPT), arms muscle training (AMT) associated with and of the respiratory reeducation functional techniques (RFR) on asthmatic patients. The cardiopulmonary function was evaluated before and after the physical training. It was analyzed the Maximal and Submaximal c
