JF - European Respiratory Review JO - EUROPEAN RESPIRATORY REVIEW DO - 10.1183/16000617.0253-2021 VL - 31 IS - 164 SP - 210253 AU - Nicola Borasio AU - Marco Vecchiato AU - Giulia Quinto AU - Francesca Battista AU - Daniel Neunhaeuserer AU - Andrea Ermolao Y1 - 2022/06/30 UR - http://err.ersjournals.com/content/31/164/210253.abstract N2 - Collins et al. [1] discussed the pathophysiological mechanisms and clinical relevance of ventilatory efficiency in athletes, asthma and obesity in their interesting review article entitled “Ventilatory efficiency in athletes, asthma and obesity”. Patients with obesity can display an altered ventilatory response to exercise, which may contribute to functional limitations in this population. We aim to provide a supplementary contribution to the clinical evaluation and pathophysiological interpretation of the ventilatory response to exercise in patients with obesity. This contribution resulted from two papers recently published by our research group.Patients with obesity may have different ventilatory phenotypes during exercise related to an interaction of expiratory flow limitation, mechanical constraints and adaptations of chemoreception and metabolic setpoints. https://bit.ly/3JBs86S ER -
