1. Evaluation of a rat model of exercise-induced fatigue using treadmill running with progressively increasing load
Abstract: The mechanism behind exercise-induced fatigue is a significant topic in the field of sports physiology. Therefore, establishing and evaluating an acute exercise-induced fatigue animal model that explores the limits of the motor system may provide greater insight into these mechanisms. Heart rate is an important quantitative parameter that accuratel

2. SIX HIT TREADMILL SESSIONS IMPROVE LIPID OXIDATION AND VENTILATORY THRESHOLD INTENSITIES
RESUMO Introdução: O treinamento cardiorrespiratório intervalado de alta intensidade (high-intensity interval training, HIT) tem sido utilizado como alternativa ao treinamento cardiorrespiratório contínuo de intensidade submáxima e duração prolongada. Objetivo: Propor um protocolo de HIT utilizando corrida em esteira e verificar a influência de se

3. ACUTE EFFECT OF DIFFERENT TYPES OF EXERCISE ON NATRIURETIC PEPTIDES OF WISTAR RATS
RESUMO Introdução: O estudo dos efeitos de diferentes tipos de exercício físico na fisiologia cardiovascular está aumentando na literatura. Os muitos mecanismos de controle hemodinâmico incluem a liberação atrial de peptídeos natriuréticos. Embora amplas evidências demonstrem seus efeitos agudos e o aumento na sua concentração plasmática, não

4. Inter-Individual Responses to Citrulline Malate Oral Supplementation on Post-Exercise Hypotension in Hypertensives: A 24-Hour Analysis
Resumo Fundamento: Estudos demonstraram de maneira persuasiva que a citrulina tem um papel fundamental no sistema arginina-óxido nítrico, aumentando a biodisponibilidade do óxido nítrico, um importante mediador da vasodilatação periférica. Objetivo: Analisar a responsividade interindividual da hipotensão pós-exercício após suplementação agud

5. Moderate-intensity exercise allows enhanced protection against oxidative stress-induced cardiac dysfunction in spontaneously hypertensive rats
The progression of myocardial injury secondary to hypertension is a complex process related to a series of physiological and molecular factors including oxidative stress. This study aimed to investigate whether moderate-intensity exercise (MIE) could improve cardiac function and oxidative stress in spontaneously hypertensive rats (SHRs). Eight-week-old male

6. VALIDATION OF SMARTPHONE FREE HEART RATE MONITORING APPLICATION DURING TREADMILL EXERCISE
RESUMO Objetivo: O número de pessoas que participam em atividades esportivas de lazer e competições amadoras aumentou acentuadamente nos últimos anos. Os aplicativos gratuitos para monitoramento da frequência cardíaca para smartphone estão disponíveis para uso; no entanto, as informações sobre sua precisão durante o exercício ainda são limitada

7. Voluntary wheel running: patterns and physiological effects in mice
Exercise can prevent and improve the pathophysiology of diseases and promote healthy aging. Thus, understanding the mechanisms that regulate the beneficial effects of exercise may lead to the development of new strategies to enhance quality of life and to counteract chronic diseases. Voluntary wheel running is an interesting model to study the effects of exe

8. Comparison of endoplasmic reticulum stress and mitochondrial biogenesis responses after 12 weeks of treadmill running and ladder climbing exercises in the cardiac muscle of middle-aged obese rats
The purpose of the present study was to compare the influence of aerobic exercise (AE) lasting 12 weeks to that of resistance exercise (RE) of the same duration on endoplasmic reticulum (ER) stress and mitochondrial biogenesis in the cardiac muscle of middle-aged obese rats. Obesity was induced in thirty 50-week-old male Sprague Dawley rats over 6 weeks by a

9. Bouts of exercise elicit discordant testosterone: cortisol ratios in runners and non-runners
ABSTRACT Objective: The testosterone:cortisol ratio (T:C) is suggested to be used in order to examine whether physical exercise generates either a “catabolic environment” or an “anabolic environment”. The present study aims to evaluate the acute time-course profile of cortisol and testosterone due to an episode of physical exercise. A biphasic profi

10. Cardiac protein expression patterns are associated with distinct inborn exercise capacity in non-selectively bred rats
In the present study, we successfully demonstrated for the first time the existence of cardiac proteomic differences between non-selectively bred rats with distinct intrinsic exercise capacities. A proteomic approach based on two-dimensional gel electrophoresis coupled to mass spectrometry was used to study the left ventricle (LV) tissue proteome of rats wit

11. Effects of a 4-week high-intensity interval training on pacing during 5-km running trial
This study analyzed the influence of a 4-week high-intensity interval training on the pacing strategy adopted by runners during a 5-km running trial. Sixteen male recreational long-distance runners were randomly assigned to a control group (CON, n=8) or a high-intensity interval training group (HIIT, n=8). The HIIT group performed high-intensity interval-tra

12. Effects of endurance training on reduction of plasma glucose during high intensity constant and incremental speed tests in Wistar rats
The aim of this research was to investigate the effects of endurance training on reduction of plasma glucose during high intensity constant and incremental speed tests in Wistar rats. We hypothesized that plasma glucose might be decreased in the exercised group during heavy (more intense) exercise. Twenty-four 10-week-old male Wistar rats were randomly assig
