Subjects
The study included 64 older adults who volunteered to participate in an outpatient pulmonary rehabilitation program at Duke University Medical Center. Criteria for inclusion in the study were: (1) age =50 years, (2) symptoms for more than six months, and (3) the ***FEV1/FVC ratio <0.70. Participants ranged in age from 53 to 82 years (mean = 67.4 ± 7.0 years), and were approximately evenly distributed by gender (35 male [55 percent], 29 female [45 percent]).
Exercise Rehabilitation Program
Participants attended the program in
Adherence
Of the 64 subjects assessed at time 1, 61 subjects (95 percent) completed the 30-day program. Two females and one male dropped out, leaving 34 males and 27 females with complete data.
Pulmonary Function
Changes in pulmonary function were tested in a MANOVA of three variables: FVC, FEV1 and MVV. The MANOVA indicated a gender main effect (F[3,56] = 14.08, p<0.001) and time main effect (F[3,57] = 10.05, p<0.001), but no interaction effect. Univariate testing indicated that all three measures of pulmonary function
DISCUSSION
These data suggest the efficacy of exercise rehabilitation among both male and female older adults with COPD. Participants in the 30-day exercise rehabilitation program achieved significant improvement in pulmonary function, physical endurance and functional capacity. In addition, participants experienced enhanced psychological well-being, as indicated by reduced affective distress and improved cognitive functioning.
The greater functional and work capacity among males as opposed to females is

Effects of exercise training on cognition in chronic obstructive pulmonary disease: A systematic review
2018, Respiratory MedicineCitation Excerpt :In a crossover experimental trial, strenuous exercise acutely improved verbal fluency compared to video watching [16]. Although longer-term trials of exercise on cognition in COPD have been reported [17–23], the heterogeneity of exercise training as well as cognitive outcome used makes it difficult to draw clear conclusions. Therefore, the objectives of the present systematic review were to: i) describe the exercise training interventions designed to improve cognition in COPD, and ii) document their impact.

2015, Contemporary Clinical TrialsCitation Excerpt :Patients with COPD are at high risk of developing symptoms of anxiety and depression [6,7]. Anxiety over dyspnea-producing activities is common and may promote maladaptive sedentary lifestyles [74,75]. Inherent in mind–body exercises such as Tai Chi is training in mindfulness, stress-reduction and other relaxation techniques that may improve mood, perceived stress, and directly address anxiety and depression-related factors.
