1. Association between the increase in brain temperature and physical performance at different exercise intensities and protocols in a temperate environment
There is evidence that brain temperature (Tbrain) provides a more sensitive index than other core body temperatures in determining physical performance. However, no study has addressed whether the association between performance and increases in Tbrain in a temperate environment is dependent upon exercise intensity, and this was the primary aim of the presen

2. Determinação do limiar de lactato e do máximo estado estável de lactato em comundongos ob/ob na natação
Obesity is a chronic metabolic disturb of multiple ethiology and a high prevalence worldwide. It is also associated to several diseases. One type of non-pharmachological treatment of obesity is the physical exercise. Although many researchers have been performed in animal models, there is a lack in the literature of studies analyzing aerobic capacity assessm

3. The influence of the different information about the time of the exercise on the eletromyographic and the oxygen uptake at cyclists / Influencia de diferentes informações quanto ao tempo de realização do exercicio sobre a atividade eletromiografica e consumo de oxigenio em ciclistas
The purpose of this study was to evaluate the effect of different information about the time of the test to be helded on specific physiological variables. Ten men cyclists (1.76 ± 0.04 m, 78.48 ± 10.40 kg and 32.5 ± 6.02 years old)was submitted to a incremental test (beginning of 100W and increased 20W.min - 1) to determine the peak power (PP) (369.84 ±

4. Heart rate variability threshold in different ergometric protocols / Limiar de variabilidade da freqüência cardíaca em diferentes protocolos ergométricos
The heart rate variability (VFC) decreases gradually during progressive exercise, which tends to stabilization in intermediate loads. Initially, the possibility of identification of a threshold of this variable (LiVFC1), assumed as demarcating of the transition of the vagal withdrawal for the predominance of the sympathetic activity in the control of the FC

5. IdentificaÃÃo dos limiares de lactato, glicÃmico e ventilatÃrio e efeitos da intensidade do exercÃcio resistido sobre a glicemia em diabÃticos tipo-2
The aim of this study were: 1) to identify the incidence and compare the lactate (LT), glycemic (IGT) and ventilatory thresholds (VT) in cycle ergometer, as well as the lactate (LT)and glycemic thresholds (GT) in resistance exercise in type 2 diabetics; 2) to correlate the thresholds on cycle ergometer with the thresholds determined on resistance exercises;

6. Histamine reactivity during the refractory period after exercise induced asthma.
An episode of exercise induced asthma will usually be followed by a period during which further exercise will not induce asthma. Postulated mechanisms include persistence of catecholamines released during exercise, development of tolerance to released mediators, and mediator depletion. To investigate the underlying mechanism further eight asthmatic men under

7. Dyspnoea assessed by visual analogue scale in patients with chronic obstructive lung disease during progressive and high intensity exercise.
BACKGROUND: A study was carried out to determine whether rating of dyspnoea by means of a visual analogue scale during a progressive exercise test is affected by the subject's awareness of the progressive nature of the protocol. METHODS: Nineteen patients with chronic obstructive lung disease (FEV1 mean (SE) 1.06 (0.07) 1) were studied. A preliminary increme

8. Adenosine receptor antagonist and augmented vasodilation during hypoxic exercise
We tested the hypothesis that adenosine contributes to augmented skeletal muscle vasodilation during hypoxic exercise. In separate protocols, subjects performed incremental rhythmic forearm exercise (10% and 20% of maximum) during normoxia and normocapnic hypoxia (80% arterial O2 saturation). In protocol 1 (n = 8), subjects received an intra-arterial adminis

9. Active forearm blood flow adjustments to handgrip exercise in young and older healthy men.
1. Our purpose was to test the hypothesis that ageing impairs the active muscle hyperaemia consequent to dynamic exercise in humans. 2. Eleven young (19-29 years) and eleven older (60-74 years) healthy, non-obese men with similar chronic physical activity levels and forearm size performed two protocols of dynamic handgrip exercise: (a) brief (1 min), increme

10. Development of a shuttle walking test of disability in patients with chronic airways obstruction.
BACKGROUND: The aim was to develop a standardised and externally paced field walking test, incorporating an incremental and progressive structure, to assess functional capacity in patients with chronic airways obstruction. METHODS: The usefulness of two different shuttle walking test protocols was examined in two separate groups of patients. The initial 10 l
