In the present study cardio-vascular adaptation to graded exercise was studied in untrained male medical students. The subjects were given two grades of exercise each lasting for about five minutes with a rest of fifteen minutes in between on a mechanically braked bicycle ergometer. There was a statistically significant rise in the heart rate during both the exercise sessions. This rise was per...

The aim of the present study was to analyse the usefulness of the 6-20 rating of perceived exertion (RPE) scale for prescribing and self-regulating high-intensity interval training (HIT) in young individuals. Eight healthy young subjects (age = 27.5±6.7 years) performed maximal graded exercise testing to determine their maximal and reserve heart rate (HR). Subjects then performed two HIT sessio...

Contamination is commonly overlooked in randomized trials. The present study examined contamination (minutes of aerobic activity outside of exercise sessions) within an active control condition in a 6-month randomized exercise trial for older adults. We hypothesized that outside aerobic activity would be greater in the control condition compared to the intervention conditions. Participants (mea...

BACKGROUND/AIMS This study examines the feasibility of a preoperative exercise program to improve the physical fitness of a patient before gastrointestinal surgery. METHODS An outpatient exercise program was developed to increase preoperative aerobic capacity, peripheral muscle endurance and respiratory muscle function in patients with pancreatic, liver, intestinal, gastric or esophageal canc...

BACKGROUND The effect of exercise during hemodialysis has been a controversial issue, however, there are just few studies about the effect of active exercise during hemodialysis. OBJECTIVES This study aimed to compare the effects of passive and active intradialytic pedaling exercises on dialysis efficacy, electrolytes, hemoglobin, hematocrit, blood pressure and health-related quality of life ...

Six sessions of high-intensity interval training (HIT) are sufficient to improve exercise capacity. The mechanisms explaining such improvements are unclear. Accordingly, the aim of this study was to perform a comprehensive evaluation of physiologically relevant adaptations occurring after six sessions of HIT to determine the mechanisms explaining improvements in exercise performance. Sixteen un...

Hypertension is a chronic disease that affects about 30% of the world's population, and the physical exercise plays an important role on its non-pharmacological treatment. Anywise, the dose-response of physical exercise fractionation throughout the day demands more investigation, allowing new exercise prescription possibilities. Therefore, this study aimed to analyze the acute blood pressure (B...

Skeletal muscle gene response to exercise depends on nutritional status during and after exercise, but it is unknown whether muscle adaptations to endurance training are affected by nutritional status during training sessions. Therefore, this study investigated the effect of an endurance training program (6 wk, 3 day/wk, 1-2 h, 75% of peak Vo(2)) in moderately active males. They trained in the ...

Aim: The study aimed to quantify and characterize the Training Load (TL) in a Functional (FT) model using Heart Rate (HR) Session Rating of Perceived Exertion (sRPE) methods, verify whether these methods could be valid monitor TL during FT program. Methods: design consisted two phases: phase 1 - composed single training session (FTSESSION), which HR, sRPE, pre- post-exercise lactate [La] levels...
