Introduction: Patients in the intensive care unit (ICU) have several deleterious effects of immobilization, including weakness acquired in the ICU. Exercise appears as an alternative for early mobilization in these patients. Objective: This work aims to highlight the hemodynamic repercussions and the applicability of exercise in the ICU. Methods: An integrative literature review was carried out, with articles published between 2010 and 2018, in the Lilacs, PubMed and Scielo databases, using the following search terms: exercise, cycle ergometer, intensive care units, early mobilization, mechanical ventilation, artificial respiration. Results: 13 articles were included, addressing hemodynamic monitoring and the role of exercise as early mobilization, with or without ventilatory support. The exercise sessions were feasible and safe within the ICU environment. Conclusion: Physical exercise can be performed safely in an ICU environment, if respecting a series of criteria such as those presented here. It is important that the assistant professional seeks to prescribe interventions based on Exercise Physiology that can positively intervene in the functional prognosis in critically ill patients.Keywords: exercise, intensive care units, patient safety.

ABSTRACT Treadmill walking produced a prompt reduction in serum cortisol in 10 of 12 healthy military men. In contrast, two subjects, with pre-exercise tachycardia and apprehension, showed an increase in serum cortisol with treadmill exercise. In each group, the changes produced by exercise were still evident 30 and 60 minutes after the 30-minute treadmill walk. Urine collected before and after exercise contained similar amounts of 11-hydroxy- and 17-hydroxycorticosteroid material. These results may be explained by an increase in cortisol utilization during exercise and/or by a change in its distribution. The data indicate that in the absence of psychic factors, non-exhaustive exercise is not associated with pituitary adrenocortical activation.

ABSTRACT Background: Multiple sclerosis (MS) is an autoimmune disease that impacts the central nervous system. MS generally results in decreased mobility and work capacity. Our objective was to determine exercise testing responses on both a treadmill and cycle ergometer among individuals with MS who were able to ambulate freely. Methods: Twenty-six individuals with MS participated in a cross-sectional study (44 ± 11 years; body mass index 26.8 ± 6.2 kg·m−2; expanded disability scale score 3.1 ± 0.9), with 24 individuals with complete test data for both treadmill and cycle ergometry tests. Peak aerobic capacity (VO2peak) for both treadmill and cycle ergometry tests were measured with indirect calorimetry. Results: Participants safely completed both treadmill and cycle ergometry tests, and treadmill testing yielded higher values (26.7 ± 6.4 mL·kg−1·min−1) compared with cycle ergometry (23.7 ± 5.7 mL·kg−1·min−1), with values ~12% greater for treadmill. When comparing tests to their respected predicted values within modality, treadmill tests were 8% lower and cycle ergometry tests were 10% lower than predicted. Conclusions: While peak aerobic capacity was very low for this population, treadmill tests were still higher than cycle ergometry data, with this difference between modes being similar to that observed in healthy adult populations. Additional research is required to determine if these findings are impacted by participation in physical activity or regular exercise.

Higher exercise blood pressure represents low cardiorespiratory status of an individual and vice versa. Thechanges in systolic and diastolic blood pressure in response to rhythmic isotonic muscular exercise in sedentaryyoung normotensive Nepalese students were assessed. Normal blood pressure in standing posture in maleand female subjects are about 115 / 75 mm of Hg. and 106 / 71 mm of Hg. respectively. Just after the exercisesystolic blood pressure increases moderately in both the sexes, whereas diastolic blood pressure remainsunchanged in most of the females. Diastolic blood pressure is found to be decreased slightly in the males,just after exercise. The present study indicates the cardiorespiratory status of the Napalese medical studentsis within normal range.

The correlation between postprandial triglyceridemia and plasma viscosity was studied in 45 healthy young men. One-half, 23, of them carried out a heavy march lasting 2 hr while the other half, 22, rested in bed. Serum triglycerides and plasma viscosity were determined before the fat meal and 4 and 6 hr postprandially. Serum total proteins and hematocrits were measured simultaneously. Despite significantly higher postprandial triglyceridemia in the resting group no rise was seen in plasma viscosity, whereas, in the exercise group with a lower triglyceride level a significant elevation took place in plasma viscosity. serum triglycerides Submitted on February 18, 1963

CONTEXT AND OBJECTIVE: The change in slope of the VE/VCO2 curve with time during exercise (VE/VCO2 slope) has been recommended as a parameter for analyzing the ventilatory response during exercise among patients with heart failure of different etiologies. The aim of this work was to evaluate the ventilatory response among patients with chronic Chagas cardiopathy. METHODS: Forty-eight patients, divided into four groups according to the Los Andes clinical/hemodynamic classification, were studied. They were also classified according to peak oxygen uptake (peak VO2) for a second analysis. The results from the patients were compared with results from a control group consisting of 21 healthy male volunteers (no Chagas disease). Exercise was performed on a cycle ergometer with loads increasing at the rate of 12.5 watts/min, and exercise duration was symptom-limited. Gas concentration and flow rate data were fed into a computer, which produced a real-time report on ventilatory and gas exchange parameters (breath-by-breath). The ventilatory parameters of VE/VCO2 slope and VE/VCO2 ratio computed at different times of the test were adopted. RESULTS: Although there were no significant differences in VE/VCO2 ratio and VE/VCO2 slope when patients were grouped using the Los Andes clinical/hemodynamic classification, these parameters varied significantly when peak VO2 was used to define patient groups. CONCLUSION: Our results indicate that progressive deterioration in ventilatory response among chronic Chagas cardiopathy patients during exercise is more evident when the functional capacity (peak VO2) is reduced, than when changes are related to the Los Andes classification.
