1. Ischemic preconditioning delays the time of exhaustion in cycling performance during the early but not in the late phase
Abstract Aims: To investigate the early and late ischemic preconditioning (IPC) effect on the trained cyclists’ performance during incremental cycling test until exhaustion. Methods: Twenty-one male cyclists allocated to an IPC (2 x 5-min of blood flow occlusion at 50 mm Hg above systolic pressure followed + 5-min of deflation), SHAM (2 x 5-min at 20 m

2. Evaluation of maximal lactate steady state in middle-aged hypertensive women
Abstract AIM The aim of this study was to investigate the lactate response in physically inactive hypertensive women submitted to the treadmill maximal lactate steady state (MLSS) protocol. METHODS Twenty-two hypertensive women (40 - 64 years) performed a familiarization period of walking on the treadmill following by one incremental test for estimating th

3. Carbohydrate mouth rinse reduces rating of perceived exertion but does not affect performance and energy systems contribution during a high-intensity exercise
ABSTRACT Aim The study aimed to verify the effect of carbohydrate (CHO) mouth rinse on time to exhaustion, energy systems contribution and rating of perceived exertion (RPE) during a high-intensity exercise. Methods Fourteen men performed an incremental exercise test to determine their maximal oxygen uptake and peak power output (PPO) and two time-to-exhau

4. 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

5. 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

6. Identification and agreement of first turn point by mathematical analysis applied to heart rate, carbon dioxide output and electromyography
BACKGROUND: The second heart rate (HR) turn point has been extensively studied, however there are few studies determining the first HR turn point. Also, the use of mathematical and statistical models for determining changes in dynamic characteristics of physiological variables during an incremental cardiopulmonary test has been suggested. OBJECTIVES: To

7. 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

8. Efeito do treinamento de musculação em circuito sobre a aptidão cardiorrespiratória e citocinas plasmáticas IL-6, IL-8, IL-10, TNF, IL-1β e IL-12p70 em mulheres saudáveis / Efeito do treinamento de musculação em circuito sobre a aptidão cardiorrespiratória e citocinas plasmáticas IL-6, IL-8, IL-10, TNF, IL-1β e IL-12p70 em mulheres saudáveis
There are evidences demonstrating that long-term aerobic exercises boost the plasmatic cytokines concentrations. However, there are few researches that deal with that relation in short-term and high intensity ones. This study aims at verifying the effects of strength training in circuit over the cardiorespiratory competence response and also over the plasmat

9. 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

10. Efeito da terapia estrogênica sobre o controle autonômico da freqüência cardíaca e a capacidade aeróbia de mulheres saudáveis.
The effects of female sex hormones on the cardiovascular system have been the topic of much discussion and controversy in the literature. Nevertheless, many scientists believe that estrogens play an important cardioprotective role in premenopausal women, with their effects being observed directly on blood vessels or indirectly by the promotion of an antiathe

11. Efeito da suplementaÃÃo de cafeÃna sobre biomarcadores salivares e plasmÃticos em ciclistas e praticantes de spinning durante teste incremental no cicloergÃmetro
This study investigated the effect of the caffeine ingestion in the salivary biomarkers, blood lactate and the physical performance, during incremental test in cycle ergometer. We tested 16 cycle men and practitioners of spinning in an adaptative test, phase A, and after the ingestion of placebo and caffeine (5mg/kg), phase B. The exercise protocol was initi

12. Efeitos do exercício agudo em cicloergômetro sobre parâmetros hemodinâmicos em indivíduos diabéticos
Type 2 diabetes mellitus if develops in result of the lack of insulin or the incapacity of the insulin to exert adequately its effect. For type 2 diabetic the inadequate glicemic control can contribute for the appearance of other illnesses, between them the cardiovascular illnesses and the arterial hypertension. The not pharmacologic treatment more recommend
