Randomized Controlled Trial Comparative StudyBreathing helium-hyperoxia and tolerance of partitioned exercise in patients with COPD.
Partitioning exercise by 1-legged cycling is more effective than conventional training in patients with chronic obstructive pulmonary disease. Similarly, inhaling helium-hyperoxia can extend conventional exercise tolerance. This study aimed to determine whether breathing helium-hyperoxia could increase the tolerance of a high-intensity exercise session achieved by 1-legged cycling. ⋯ Inspiring a helium-hyperoxia mixture does not increase the endurance of what would be a typical training session, breathing supplemental oxygen, of high-intensity 1-legged constant power exercise. Leg muscle fatigue was similar after 1-legged exercise with and without breathing the helium mixture.

Randomized Controlled TrialDeep breathing exercises performed 2 months following cardiac surgery: a randomized controlled trial.
Postoperative breathing exercises are recommended to cardiac surgery patients. Instructions concerning how long patients should continue exercises after discharge vary, and the significance of treatment needs to be determined. Our aim was to assess the effects of home-based deep breathing exercises performed with a positive expiratory pressure device for 2 months following cardiac surgery. ⋯ No significant differences in lung function, subjective perceptions, or quality of life were found between patients performing home-based deep breathing exercises and control patients 2 months after cardiac surgery.

Randomized Controlled TrialDevelopment and feasibility of a self-management intervention for chronic obstructive pulmonary disease delivered with motivational interviewing strategies.
Self-management is proposed as the standard of care in chronic obstructive pulmonary disease (COPD), but details of the process and training required to deliver effective self-management are not widely available. In addition, recent data suggest that patient engagement and motivation are critical ingredients for effective self-management. This article carefully describes a self-management intervention using motivational interviewing skills, aimed to increase engagement and commitment in severe COPD patients. ⋯ A self-management intervention that includes motivational interviewing as the way if guiding patients into behavior change is feasible in severe COPD and may increase patient engagement and commitment to self-management. This provides a very detailed description of the process for the specifics of training and delivering the intervention, which facilitates replicability in other settings and could be translated to cardiac rehabilitation.

Randomized Controlled TrialThe addition of strength training to aerobic interval training: effects on muscle strength and body composition in CHF patients.
The loss of lean muscle mass and muscle strength is a common problem in chronic heart failure (CHF) patients. Endurance training is efficient in improving patient exercise capacity. This study sought to evaluate the additional effects of strength training on muscle strength and body composition in chf patients participating in an interval training program. ⋯ Combined aerobic interval and strength training induces a greater benefit than interval training alone on muscle strength in CHF patients. Adaptations other than hypertrophy, such as muscle fiber type alterations and/or neuromuscular adjustments, may account for these results.

Randomized Controlled Trial Comparative StudyPulmonary rehabilitation after acute exacerbation of chronic obstructive pulmonary disease in patients who previously completed a pulmonary rehabilitation program.
Acute exacerbations of chronic obstructive pulmonary disease (AECOPD) impair health-related quality of life (HRQL). We evaluated the effect of an abbreviated repeat pulmonary rehabilitation (PR) program on HRQL after an AECOPD. ⋯ The reduction in dyspnea in those who did not experience a second AECOPD provides preliminary evidence for the role of repeat programs. The application of repeat PR should be refined in larger trials.
