TI  - Freedive Training Gives Additional Physiological Effect Compared to Pulmonary 
      Rehabilitation in COPD.

AB  - INTRODUCTION: Pulmonary rehabilitation (PR) is beneficial for lung mechanics, 
      chest kinematics, metabolism, and inspiratory and peripheral muscle function. 
      Freediving training (FD) can be effective in sportsmen and can improve 
      breath-holding time. AIMS: We sought to determine the effectiveness of freediving 
      training in the pulmonary rehabilitation of COPD patients. PATIENTS AND METHODS: 
      Twenty-three COPD patients (15 men and 8 women; median age 63 years; FEV1: 41% 
      pred; BMI: 28 kg/m(2)) participated in the FD + PR group (3 weeks PR and 3 weeks 
      FD + PR) and 46 patients with COPD (25 men and 21 women; median age 66 years; 
      FEV1: 43% pred; BMI: 27 kg/m(2)) participated in an inpatient PR program (6 
      weeks). Patients performed comfort zone breath holding for 30 min/day. Patients 
      increased their breath-holding time within their comfort zone for 30 min. We 
      detected lung function, chest expansion (CWE), inspiratory muscle pressure (MIP), 
      peripheral muscle function (GS), and exercise capacity (6MWD), and we included 
      breath-holding time (BHT), quality of life score (COPD Assessment Test (CAT)), 
      modified Medical Research Dyspnea Scale (mMRC) score, and the severity of the 
      disease assessed by the BODE index (FEV1, BMI, 6MWD, and mMRC) and an alternative 
      scale (FEV1, BMI, 6MWD, and CAT). RESULT: There were significant differences in 
      the characteristics of the two groups. Significant improvement was detected in 
      all functional and quality of life parameters except lung function in both 
      groups. Significantly higher improvement was detected in CWE, GS, 6MWD, BHT, CAT, 
      mMRC, alternative scale, and MIP. The improvement in forced vital capacity (FVC) 
      was not significant. There were no side effects of FD training. CONCLUSION: The 
      FD method can potentiate the effect of PR, improving not only BHT but also other 
      parameters. TRIAL REGISTRATION: ISRCTN ISRCTN13019180. Registered 19 December
