ObjectiveThe objective of this study was to use a cycle ergometer to assess cardiorespiratory changes during active exercise and to verify patients' satisfaction with this type of activity. Methods A single intervention involving active lower limb exercise was performed with a cycle ergometer (without load) for 5 minutes. The following variables were measured before, during and immediately after exercise: heart rate, blood pressure, respiratory rate, peripheral oxygen saturation and the Borg dyspnea scale score. Following the exercise, the patients answered a questionnaire to evaluate their satisfaction with this type of activity. Results A total of 38 patients (65% male) with a mean age of 48 ± 16 years old participated in the study. Enrolled patients presented a sequential organ failure assessment (SOFA) score of 2 (0 - 5 scale). During the exercise, 16% of the patients used ventilation support and 55% of them were breathing at room air. A comparison of the initial and final values of the variables indicated increases in the heart rate (92±17 beats/min vs. 95±18 beats/min; p<0.05), the respiratory rate (19 ± 8 breaths/min vs. 23±8 breaths/min; p<0.05) and the Borg dyspnea scale score (1.3±1.8 vs. 2.8±2.2; p<0.05). In addition, 85% of the patients reported enjoying the activity. Only 25% of the patients reported some discomfort, and 100% of the patients wanted to repeat this type of activity in future treatments. ConclusionDuring the cycle ergometer exercises, minor cardiorespiratory changes were observed in the patients. The evaluated patients reported high satisfaction with this type of activity.
The teaching-learning process is challenging in human anatomy. In this process, practical exams are necessary to enable a proper evaluation of the students. Students’ performance, on the other hand, reflects not only their knowledge but also their individual reactions to exams. Objective: This study aimed to identify signs and symptoms of stress in undergraduate students before practical exams in human anatomy. Methods: The sample consisted of 93 students (48 females and 45 males, mean age = 20.33 years) enrolled in medical and dental courses at undergraduate level. Blood rate, heart rate and oxygen saturation were assessed 30 minutes before the practical exams. Lipp´s Inventory of Stress Symptoms for Adults (LSSI) was used. Results: Statistically significant differences (p < 0.05) was observed for the systolic blood pressure between females (117.76 11.82 mmHg) and males (120.66 10.09 mmHg). Diastolic rate, respiratory rate and oxygen saturation were similar between sex groups (p > 0.05). A higher report of signs and symptoms of stress was detected in females (p < 0.05) for each of the stress stages described by LSSI, namely alarm, resistance and exhaustion. Medical and dental undergraduate students manifested signs and symptoms of stress before practical exams in human anatomy. The outcomes were more evident in females.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
