OBJECTIVE To study the acute aftereffects of exercise and relaxation, performed alone and in combination, on blood pressure (BP) measured at baseline and during stressful conditions. DESIGN Clinical trial with comparison of groups and repeated measures in each group. SETTING Exercise Hemodynamic Laboratory, University of São Paulo, Brazil. PARTICIPANTS Fourteen normotensive (NT) and 16 es...

OBJECTIVE Cardiovascular drift (CVdrift) is characterised by a continuous, gradual increase in heart rate (HR) after approximately 10 min of moderate-intensity aerobic exercise, despite maintenance of a constant work rate. This has important implications for trials that employ HR to monitor exercise intensity, as reducing work rate in order to keep HR constant could result in participants exerc...

Hematocrit has been implicated in the triggering of cardiovascular events and the development of cardiovascular disease. Studies have demonstrated the reliability of hematocrit at rest, however, data are lacking about hematocrit during repeated acute stress exposures. The current study assessed the reliability of hematocrit during rest and stress. Hematocrit was measured in two sessions during ...

background & objectives: several epidemiological studies have indicated factors such as leptin level, adiponectin and plasma adiponectin-to-leptin index to be the predicting biomarkers for cardiovascular diseases. given the importance of healthy nutrition and adequate exercise in reducing the risk of atherosclerosis, this study aimed to investigate the effects of fasting and aerobic exercise on...

BACKGROUND Different methods of measuring blood pressure (BP) have been used in clinical and scientific evaluations. However, the methods employed have constraints and peculiarities to be considered. OBJECTIVE To evaluate whether similar BP values are obtained in elderly hypertensive patients undergoing resistance exercises when using the oscillometric (Omron-HEM-431) and auscultatory methods...

OBJECTIVE To investigate the effect of treadmill walking exercise as a treatment method to improve gait efficiency in adults with cerebral palsy (CP) and to determine gait efficiency during overground walking after the treadmill walking exercise. METHODS Fourteen adults with CP were recruited in the experimental group of treadmill walking exercise. A control group of 7 adults with CP who atte...

During physically interactive video game play (e.g., Nintendo Wii), users are exposed to potential distracters (e.g., video, music), which may decrease their ratings of perceived exertion (RPE) throughout game play. The purpose of this investigation was to determine the association between RPE scores and heart rate while playing the Nintendo Wii. Healthy adults (N = 13, 53.5 ± 5.4 years old) pa...

the aim of this study was to compare the effect of an aerobic exercise program with two different volumes on some risk factors of cardiovascular diseases in mentally retarded girls. 24 mentally retarded girls were randomly assigned to three groups: 1) aerobic exercise, 3 sessions per week for 45 minutes, 2) aerobic exercise, 4 sessions per week for 40 minutes, and 3) control. the experimental g...

OBJECTIVE Evaluate the effect of different exercise intensities on spontaneous physical activity energy expenditure in overweight adolescents. METHODS A crossover study was developed with a control session, followed by moderate and vigorous exercise sessions, with six days of monitoring each. Twenty-four adolescents, 11-13 years old, male and overweight were selected. Spontaneous physical act...
