Many COVID-19 survivors worldwide suffer from persistent symptoms, impaired functional capacity and quality of life. Rehabilitation exercise interventions for the long-term physical consequences of coronavirus disease 2019 (COVID-19) are currently being reported. As a result, the clinical practice and research focus on interventions that support recovery from ongoing symptomatology, independently to hospitalization. To date, the outpatient rehabilitation programs offer various exercise modes and training intensities for people recovering from long-term symptomatology of COVID-19. This narrative review summarizes previous studies that used exercise training protocols at the outpatient rehabilitation setting, presents the effectiveness of training on the functional outcomes and provides practical issues of the application of exercise training which overcome possible respiratory and peripheral muscle limiting factors of exercise and functional capacity for patients with Long-COVID-19. To this end we make recommendations on how better to implement exercise training in future studies so as to maximize training effects. Due to lack of randomized trials, more research is needed in the field of the exercise training modalities that are more effective and in parallel more tolerable for patients with persistent post-COVID-19 symptoms. In this context, interval training mode with short exercise periods can prevent high lactate accumulation and allow more intense exercise stimuli to the deconditioned peripheral muscles with minimal cardiac strain and exercise-induced hyperventilation, thus improving exercise capacity in this patients’ population.

<p class="abstract"><strong>Background:</strong> Optimal adherence to pharmacological and non-pharmacological treatment in pediatric pulmonary diseases is crucial to address the increased morbidity levels. The purpose of this scoping review was to investigate the level of evidence about technical factors that facilitate adherence to non-pharmacological treatment with the use of mobile health (mHealth) in children with chronic respiratory diseases.</p><p class="abstract"><strong>Methods:</strong> The methodological framework for scoping review recommended by Arksey and O’Malley’s and Levac will be followed for conducting the present one. The preferred reporting items for systematic reviews and meta-analyses for scoping reviews (PRISMA-ScR) guidelines will be used. Methodological quality will be assessed using the critical appraisal skills programme (CASP) checklist and the mixed methods appraisal tool (MMAT). Five databases will be searched: Medline (via Ovid), PubMed, Scopus, CINAHL (EBSCOhost) and Cochrane Library. Two independent reviewers will screen titles and abstracts for assessment against the eligibility criteria. Any disagreements will be resolved through discussion and consensus among other authors. Data will be extracted and presented in a narrative summary.</p><p class="abstract"><strong>Conclusions: </strong>This scoping review does not require ethics approval as it only includes information from previously published studies. The results will be disseminated through a peer-review publication, conference presentations and/or as part of stakeholder meetings with physiotherapists, clinicians, academicians, technicians and researchers.</p><p class="abstract"><strong>Trial Registration:</strong> NA.</p>
