Although patients with chronic obstructive pulmonary disease (COPD) benefit in many ways after participating in pulmonary rehabilitation programs, high dropout rates are still observed among participants. This study aims to analyze the adherence rate and perceived satisfaction in individuals with chronic obstructive pulmonary disease who underwent high-intensity physical training on land (LG) and in water (WG). This study is an additional analysis from a randomized controlled trial. In total, 36 subjects (51%) completed the intervention. All participants underwent six months of high-intensity endurance and strength training. Adherence was assessed by the proportion of patients who completed the training program. Perceived satisfaction was evaluated using a questionnaire composed of structured and semi-structured questions. The interviews were recorded, transcribed, and analyzed according to the criteria of our thematic analysis. The Shapiro-Wilk test was used to assess data normality, and dropout rates were compared using the chi-square test. Statistical significance was set at 5%. Regarding adherence, 59% of WG participants and 44% of LG participants completed the program, with no difference between the groups (p>0.05). Individuals from both groups were equally satisfied after six months of physical training (0,05). Os indivíduos de ambos os grupos estavam igualmente satisfeitos após seis meses de treinamento físico (0,05). Ambos grupos estaban igualmente satisfechos después de seis meses de entrenamiento físico (

Dysfunctional breathing (DB) is a respiratory condition characterized by irregular breathing patterns that occur either in the absence of concurrent diseases or secondary to cardiopulmonary diseases. Although the primary symptom is often dyspnea or “air hunger”, DB is also associated with nonrespiratory symptoms such as dizziness and palpitations. DB has been identified across all ages. Its prevalence among adults in primary care in the United Kingdom is approximately 9.5%. In addition, among individuals with asthma, a positive diagnosis of DB is found in a third of women and a fifth of men. Although DB has been investigated for decades, it remains poorly understood because of a paucity of high-quality clinical trials and validated outcome measures specific to this population. Accordingly, DB is often underdiagnosed or misdiagnosed, given the similarity of its associated symptoms (dyspnea, tachycardia, and dizziness) to those of other common cardiopulmonary diseases such as COPD and asthma. The high rates of misdiagnosis of DB suggest that health care professionals do not fully understand this condition and may therefore fail to provide patients with an appropriate treatment. Given the multifarious, psychophysiological nature of DB, a holistic, multidimensional assessment would seem the most appropriate way to enhance understanding and diagnostic accuracy. The present narrative review was developed as a means of summarizing the available evidence about DB, as well as improving understanding of the condition by researchers and practitioners. RESUMO A disfunção respiratória (DR) é um quadro respiratório caracterizado por padrões respiratórios irregulares que ocorrem na ausência de doenças concomitantes ou secundariamente a doenças cardiopulmonares. Embora o principal sintoma seja frequentemente dispneia ou “fome por ar”, a DR também está associada a sintomas não respiratórios, como vertigem e palpitações. A DR pode ser identificada em todas as idades. Sua prevalência entre adultos na atenção primária no Reino Unido é de aproximadamente 9,5%. Além disso, entre indivíduos com asma, um diagnóstico positivo de DR é encontrado em um terço das mulheres e um quinto dos homens. Embora a DR tenha sido investigada por décadas, ela permanece pouco compreendida devido a uma escassez de ensaios clínicos de alta qualidade e de variáveis de desfecho validadas especificamente para essa população. Assim, a DR é frequentemente subdiagnosticada ou diagnosticada incorretamente, devido à similaridade de seus sintomas associados (dispneia, taquicardia e vertigem) aos de outras doenças cardiopulmonares comuns, como DPOC e asma. As altas taxas de diagnóstico incorreto de DR sugerem que os profissionais de saúde não entendam completamente esse quadro e possam, portanto, não fornecer aos pacientes um tratamento adequado. Dada à natureza multifatorial e psicofisiológica da DR, uma avaliação holística e multidimensional parece ser a maneira mais apropriada de melhorar a compreensão e a precisão do diagnóstico. A presente revisão foi desenvolvida como um meio de resumir as evidências disponíveis sobre DB, bem como de melhorar a compreensão do quadro por pesquisadores e profissionais.

Objective: To verify whether 30 minutes of rest between two incremental shuttle walking tests (ISWT) are enough for cardiovascular variables and perceived exertion to return to baseline values in healthy subjects in a broad age range. Method: The maximal exercise capacity of 334 apparently healthy subjects (age ≥18) was evaluated using the ISWT. The test was performed twice with 30 minutes of rest in between. Heart rate (HR), arterial blood pressure (ABP), dyspnea, and leg fatigue were evaluated before and after each test. Subjects were allocated to 6 groups according to their age: G1: 18-29 years; G2: 30-39 years; G3: 40-49 years; G4: 50-59 years; G5: 60-69 years and G6: ≥70 years. Results: All groups had a good performance in the ISWT (median >90% of the predicted distance). The initial HR (HRi) of the second ISWT was higher than the first ISWT in the total sample (p
