Cardiorespiratory fitness of a Brazilian regional sample distributed in different tables.

Background: Most classification tables of cardiorespiratory fitness (CRF) used in clinical practice are international and have not been validated for the Brazilian population. That can result in important discrepancies when that classification is extrapolated to our population.

Objective: To assess the use of major CRF tables available in a Brazilian population sample of the Central High Plan of the state of Rio Grande do Sul (RS).

Blood pressure reduction in hyper-reactive individuals after aerobic exercise.

Background: Some normotensive sedentary individuals have an exaggerated increase in blood pressure (BP) during physical activity, which is a behavior that is called blood pressure hyper-reactivity.

Objective: To investigate the effect of an aerobic exercise program (AEP) on blood pressure in individuals with blood pressure hyper-reactivity (BPH).

Methods: Ten male volunteers with BPH, aged 45 ± 10 years, referred to as the experimental group (EG), took part in an AEP on a treadmill, 3 times a week for two months.

[Lack of influence of body mass on blood pressure reduction after exercising].

Background: Hypertension (H) is associated with a large number of co-morbidities, including obesity. The correlation between two variables has been investigated.

Objective: To analyze the correlation between the loss of body mass and blood pressure reduction in hypertensive patients undergoing exercising programs (EP).

Dose-response curve to exercise in hypertensive individuals: analysis of the number of sessions to the hypotensive effect.

Background: The effect of exercise on blood pressure (BP) is already known; however, the dose-response curve of the hypotensive effect of exercise in hypertensive individuals is yet to be clarified.

Objective: To evaluate the dose-response curve of the number of sessions that are necessary to cause a hypotensive effect in hypertensive individuals.

Methods: 88 individuals, aged 58 +/- 11 years, divided in Experimental group (EG), with 48 that participated in a physical exercise program (PEP), which consisted of 40 minutes of aerobic exercises performed 3x/week, for 3 months, at 70% of the VO2max, and muscular exercises at 40% of the maximal voluntary contraction (MVC) and Control Group (CG) with 40 individuals that did not participate in the PEP.
