Aim: The aim of this study was to investigate the effects of high-intensity aerobic training (AT) and high-intensity aerobic training combined with resistance training (ie, combined training [CT]) on cognitive function in patients with COPD.
Methods: Twenty-eight Caucasian male patients (68.35±9.64 years; mean ± SD) with COPD were recruited and randomized into two groups, AT and CT. Both groups performed physical reconditioning for 4 weeks, with a frequency of five training sessions per week. The CT group completed two daily sessions of 30 minutes: one aerobic session and one strength session, respectively; The AT group performed two 30-minute aerobic endurance exercise sessions on treadmill. Physical and cognitive function tests were performed before and after the training intervention performances.
Results: Exercise training improved the following cognitive functions: long-term memory, verbal fluency, attentional capacity, apraxia, and reasoning skills (P<0.01). Moreover, the improvements in the CT group were significantly greater than those in the AT group in long-term memory, apraxia, and reasoning skills (P<0.05).
Conclusion: CT may be a possible strategy to prevent cognitive decline and associated comorbidities in male patients with COPD.
