13. 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

14. Tolerância ao esforço de hipertensos em tratamento farmacológico
The systemic hypertension is a disease with high prevalence and the major cause of cardiovascular morbid-mortality. Among the therapeutic measuresrecommendedare the modificationoflifestyle andregularphysical activity.

15. Physical training prevents body weight gain but does not modify adipose tissue gene expression
The relationship of body weight (BW) with white adipose tissue (WAT) mass and WAT gene expression pattern was investigated in mice submitted to physical training (PT). Adult male C57BL/6 mice were submitted to two 1.5-h daily swimming sessions (T, N = 18), 5 days/week for 4 weeks or maintained sedentary (S, N = 15). Citrate synthase activity increased signif

16. Avaliação laboratorial do estresse oxidativo e eletrocardiografia de cadelas submetidas a exercício / Laboratory findings of oxidative stress and electrocardiography of dogs submitted to exercise
The lack or absence of physical activity in dogs, combined with a diet high in energy has seriously affected the health of dogs, taking them to the development of various problems associated with the heart. This study aimed to study the activity of serum enzymes creatine kinase (CK), creatine kinase MB fraction (CK-MB), lactate dehydrogenase (LDH) and glutat

17. Relationship between work rate and oxygen uptake in mitochondrial myopathy during ramp-incremental exercise
We determined the response characteristics and functional correlates of the dynamic relationship between the rate (Δ) of oxygen consumption ( O2) and the applied power output (work rate = WR) during ramp-incremental exercise in patients with mitochondrial myopathy (MM). Fo

18. The slope of the oxygen pulse curve does not depend on the maximal heart rate in elite soccer players
INTRODUCTION: It is unknown whether an extremely high heart rate can affect oxygen pulse profile during progressive maximal exercise in healthy subjects. OBJECTIVE: Our aim was to compare relative oxygen pulse (adjusted for body weight) curves in athletes at their maximal heart rate during treadmill cardiopulmonary exercise testing. METHODS: A total of 180 e

19. Relação entre a oferta e a utilização muscular periférica de oxigênio na transição do exercício leve para o intenso em pacientes com insuficiência cardíaca / Peripheral muscle oxygen delivery-to-utilization mismatch in the transition from mild to heavy-intensity exercise in patients with CHF
Impaired muscle blood flow at the onset of heavy-intensity exercise may transiently reduce microvascular O2 pressure and decrease the rate of O2 transfer from capillary to mitochondria in chronic heart failure (CHF). However, advances in the pharmacological treatment of CHF (e.g., angiotensin-converting enzyme inhibitors and third generation of â-blockers)

20. Atividade enzimática da ADAMTS-13 e padrão de fragmentação do fator de von Willebrand em crianças hipoxêmicas portadoras de cardiopatias congênitas / ADAMTS-13 enzimatic activity and von Willebrand factor subunit proteolysis in children with cyanotic congenital heart disease
Hypoxia has been shown to alter several biochemical mechanisms in endothelial cells. In addition, hypoxia induces the endothelial expression of adhesion molecules, including von Willebrand factor (VWF). Increased release of high-molecular-weight VWF multimers is associated with higher risk for thrombotic events. In physiological conditions, the multimeric pa

21. Identificação dos limiares de lactato, ventilatórios e eletromiográficos em exercício resistido
Resistance training (RT) has been subject of several scientific studies, since its application not only for aesthetic purposes, but in health promotion and sports activities. To understand the determinants of physical performance is necessary to analyze biochemical, biomechanical and physiological phenomena triggered as a result of each physical activity pro

22. Blockade of the action of nitric oxide in human septic shock increases systemic vascular resistance and has detrimental effects on pulmonary function after a short infusion of methylene blue
To investigate the role of nitric oxide in human sepsis, ten patients with severe septic shock requiring vasoactive drug therapy and mechanical ventilation were enrolled in a prospective, open, non-randomized clinical trial to study the acute effects of methylene blue, an inhibitor of guanylate cyclase. Hemodynamic and metabolic variables were measured befor

23. Influência do gênero e do índice de massa corpórea na capacidade funcional em pacientes com apneia obstrutiva do sono / The influence of gender and body max index in functional capacity in OSA patients
Purpose: To evaluate the functional capacity in men and women with Obstructive Sleep Apnea (OSA) and to analyze its impact on exercise capacity and blood parameters in lean subjects. Methods: OSA patients were selected from database of Sleep Institute of Sao Paulo city. All subjects underwent clinical evaluation, blood sample withdrawal, polysomnography, a m

24. 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
