SARS-CoV-2 is a virus classified within the Betacoronavirus genus and belongs to the Coronaviridae family, which is the cause of the development of the acute respiratory syndrome known as COVID-19. Among the most common symptoms, there are fever, dry cough, expectoration, dyspnea, anosmia, ageusia, dysgeusia, sore throat, headache, myalgia, arthralgia, nausea, and vomiting (Moreover, cardiac manifestations have been described, which can be direct or indirect sequelae due to inflammatory and/or thrombocytopenia (Evaluation of the respiratory complications of COVID-19 disease covers a wide range of instrumental and functional tools (In the context of COVID-19, respiratory training plays a crucial role in the management and recovery of subjects. Some authors enhance the importance of exercise respiratory training, such as diaphragmatic breathing, nasal inspiration and active abdominal muscle contraction, with the addition of instrumental respiratory training as interventions to improve respiratory function, alleviating respiratory symptoms in individuals affected by the virus, either in the acute and post-acute rehabilitation, strongly recommending pulmonary rehabilitation due to its positive results in lung function parameters (Exercise respiratory training focuses on strengthening the respiratory muscles and improving lung capacity. It involves specific breathing exercises such as deep breathing, diaphragmatic breathing and pursed-lip breathing. These exercises aim to improve ventilatory functioning, respiratory muscles strength and quality of life (Instrumental respiratory training involves the use of specialized devices or tools to assist and optimize respiratory function. These tools, such as incentive spirometers, positive expiratory pressure devices or inspiratory muscle training devices, provide targeted respiratory exercises and facilitate lung expansion. They can help improve lung volumes, strengthen respiratory muscles, and enhance airway clearance. Some studies have explored the effect of this training in various pathologies, such as multiple sclerosis (Both exercise respiratory training and instrumental respiratory training have shown promising results in improving respiratory outcomes in COVID-19 patients. The aim of this study is to verify the effectiveness of a respiratory physiotherapy treatment protocol based in instrumental respiratory training and aerobic exercise
