The importance of using masks during exercise has increased since the coronavirus disease‐2019 (COVID‐19). This study aimed to investigate the effects of using surgical masks on gas exchange and exercise responses in maximal exercise. Twenty‐six participants were included. Participants performed the maximal exercise tests twice, masked, and unmasked. Gas exchange parameters (at maximal exercise and anaerobic threshold [AT]) and hemodynamic responses were measured. In the hemodynamic responses measured at rest, only the saturation of peripheral oxygen (SpO 2 ) was lower in the masked (mean: 97.23 ± 1.33%) measurement than in the unmasked (mean: 97.96 ± 1.07%) measurement ( p = 0.006). Test duration was lower in the masked test (unmasked: 10.32 ± 1.36 min vs. masked: 10.03 ± 1.42 min, p = 0.030). Peak oxygen consumption (VO 2peak ) (unmasked: 31.23 ± 5.37 vs. masked: 27.03 ± 6.46 ml/kg/min), minute ventilation (V E ) l/min, and energy expenditure (EE) kcal/hour were higher in unmasked tests ( p < 0.001). There was no difference in the gas exchange parameters measured at the AT in the masked and unmasked tests ( p > 0.05). Respiratory gas exchange parameters were affected in peak exercise due to increased respiratory workload, but not at the AT. There was no change in hemodynamic responses because vascular control may not be affected by mask usage.

Purpose: Reverse shoulder prosthesis is a method used after massive rotator cuff tears. It is a surgical method used to improve shoulder functions and to cope with pain. Long-term results of physiotherapy programs applied after surgery are insufficient. The aim of this study is to investigate the long-term results of reverse shoulder prosthesis applied to both shoulders. Methods: A 66-year-old female patient with a rotator cuff tear on both shoulders was included in the study. After surgery, 40 sessions of physiotherapy were applied to the left shoulder and 45 sessions of physiotherapy to the right shoulder, and the right shoulder was followed for 6 years and the left shoulder for 8 years. VAS for pain, goniometer for active range of motion, and constant shoulder score questionnaire for functionality were used in the evaluations. Results: Significant differences were found in the preoperative and postoperative evaluation in terms of pain, activities of daily living and active range of motion of the patient. While the preoperative Constant scores were 32 for the left shoulder and 34 for the right shoulder, the postoperative Constant scores were calculated as 84 for both shoulders.
