“…In turn, the modified Borg scale for the assessment of the subjective perception of effort allowed to determine in real time a safety limit for training throughout the program designed (Amorim et al, 2019). Being a scale that allows to evaluate the intensity of the sensation of effort, the user was asked during the sessions of the program, to indicate the sensation of perceived effort at a certain moment of the exercise.…”

Accountability, involvement, empowerment of the patients and families/ caregiver, as well as the incentive for health behaviors based on physical exercise and healthy living habits with the support of health professionals, are fundamental in meeting the demands of the current society. The main objective of this report is to describe the process of developing skills in rehabilitation nursing that was possible in the context of the final stage in which an intervention program in the area of cardiac rehabilitation was designed, implemented and evaluated. In this quantitative study with exploratory characteristics, it was used the collection of observable and quantifiable data, from patients submitted to coronary artery bypass grafting. During the study, the Kolmogorov-Smirnov test was applied-being verified the normal distribution-and Student t-test, which aimed at comparing outcomes at the beginning and end of the program. When 6-min walk test was applied, there was an optimization of functional capacity (P= 0.05), can be proved by the fact that all the patients had statistically significant improvements in the time-walk relationship. Furthermore, the quality of life in those who participated in the program was moderate in the preoperative period with 53.09%, and at the end a significant improvement was observed with 75.02%. Cardiac rehabilitation is fundamental in the patient submitted to coronary artery bypass grafting, taking into account the educational, physical exercise, and quality of life dimensions. Given the prevalence of risk factors associated with cardiovascular disease, differentiated intervention in rehabilitation nursing becomes essential in the training of patients for self-care.

“…However, it is extremely difficult to determine the suitable aerobic exercise intensity required for optimal improvement with minimal aerobic or even biomechanical strain (Amorim et al, 2015). The anaerobic threshold (AT), the point at which the energy required for physical activity can no longer be primarily produced by the aerobic system and must be compensated by an upregulation in anaerobic energy production during the gradual increase in exercise intensity, can be calculated using a respiratory gas analyser.…”

The effect of wearing a surgical mask on cardiopulmonary function and anaerobic threshold (AT) has not been reported. Thus, we aimed to determine whether cardiopulmonary function and AT vary while wearing surgical masks. Six healthy men were enrolled and underwent the cardiopulmonary exercise (CPX) stress test under two different conditions (with and without a commercially available surgical mask) to evaluate their AT. To confirm that there was no breath leakage, a gas mask connected with a respiratory gas analyser was worn over the surgical mask when the participants performed the CPX. The AT was measured by the V-slope method. Moreover, the AT time, exercise load, oxygen consumption, and ventilation values after the CPX were determined. No significant differences were found between the two conditions. The number of complaints of respiratory distress, however, was significantly higher while wearing a surgical mask. The exercise intensity achieved by each participant was equivalent, irrespective of whether they wore the surgical mask; therefore, wearing a surgical mask does not affect cardiopulmonary function during vigorous exercise.

“…There are discrepancies in exercise prescription approaches and the volume of training across cardiovascular rehabilitation programs, making it complex to analyze overall improvements. Other studies have found a correlation between exercise intensity and cardiorespiratory improvements such as VO2peak and functional capacity [22][23] . Our study agrees with the recommendations reviewed by Mitchell et al 22 in that we investigated adherence to exercise prescription as one of the major factors influencing functional improvements.…”

Objectives: To investigate the effect of exercise intensity on functional capacity in individuals with coronary artery disease, assess adherence to the heart rate training zone (HRTZ), and determine the relationship between trained intensity and functional capacity. Methods: A retrospective study was conducted on the medical records of 54 outpatients with coronary artery disease in a public hospital. The prescribed intensity started at 50%–60% of the heart rate reserve, increasing monthly to 70%–80% by the third month. Spearman’s test was used to assess the correlation between improvement in distance in the incremental shuttle walk test (ISWT), exercise intensity, and rating of perceived exertion (Borg–RPE). Adherence was classified as ‘below’ when HRTZ was not achieved in any phase of the program, ‘intermediate’ when HR was within the HRTZ for one or two months, and ‘above’ when HR was at or higher than HRTZ ≥ two months. Improvement was tested using t-test and one-way ANOVA. Results: 51.9% of participants had an increase in ISWT of ≥70 m (p < 0.0001). In at least one month, 50.9% trained below HRTZ. The trained intensity did not fall below 8.6% of the prescribed HRTZ minimum threshold. Changes in ISWT were not significantly correlated with exercise intensity (p = 0.87) or Borg–RPE (p = 0.16). Conclusion: While a significant increase in functional capacity was found, considerable heterogeneity in changes were observed. This may, in part, be related to adherence to HRTZ with progressive exercise intensity and to the variability in exercise volume in cardiovascular rehabilitation programs.
