7.3 Exercise Prescription for Pulmonary Diseases

Pulmonary diseases like COPD and asthma make breathing harder, which can make exercise tough. But regular workouts can actually help by boosting fitness, muscle strength, and quality of life. It's all about finding the right balance.

Exercise for lung disease patients needs to be tailored to each person. A mix of cardio, strength training, and breathing exercises can improve symptoms and overall health. Careful monitoring during workouts helps keep things safe and effective.

1 of 3

• Pulmonary diseases (COPD, asthma) cause airflow limitation, reduced lung capacity, and increased breathlessness, making exercise more challenging
• Exercise improves cardiovascular fitness, muscle strength, and endurance, leading to better overall functional capacity and quality of life
• Regular exercise reduces the frequency and severity of exacerbations by improving airway clearance and reducing inflammation
• Engaging in exercise provides psychological benefits, such as reducing anxiety and depression, and increasing self-efficacy
• Challenges during exercise include increased dyspnea, hypoxemia, and dynamic hyperinflation, which can limit exercise tolerance and increase the risk of adverse events

Physiological Adaptations to Exercise

• Ventilatory limitations lead to reduced oxygen uptake and carbon dioxide elimination, resulting in increased ventilatory demand and dyspnea
• Dynamic hyperinflation occurs when patients are unable to fully exhale before the next inhalation, leading to increased end-expiratory lung volume and reduced inspiratory capacity
• Patients may experience hypoxemia due to ventilation-perfusion mismatching and reduced diffusing capacity, which can limit exercise performance and increase the risk of adverse events
• Skeletal muscle dysfunction, including reduced muscle mass, strength, and endurance, is common and can contribute to exercise intolerance
• Pulmonary rehabilitation, which includes exercise training, leads to physiological adaptations such as improved oxidative capacity, reduced ventilatory demand, and increased skeletal muscle function

Exercise Prescription for Pulmonary Diseases

Individualized Exercise Prescription

• Exercise prescription should be individualized based on the patient's specific condition, severity, and functional capacity, as determined by exercise testing and clinical assessment
• Aerobic exercise training (walking, cycling, swimming) should be performed at a moderate intensity (60-80% of peak work rate) for 20-60 minutes per session, 3-5 times per week, to improve cardiovascular fitness and endurance
• Resistance training, using free weights, machines, or elastic bands, should be performed 2-3 times per week, targeting major muscle groups, to improve muscle strength and mass
• Breathing exercises (pursed-lip breathing, diaphragmatic breathing) should be incorporated to improve ventilatory efficiency and reduce dyspnea

Exercise Session Structure and Modifications

• Exercise sessions should include a warm-up and cool-down period
• Patients should be monitored for symptoms such as excessive dyspnea, chest pain, or desaturation, with modifications made as needed
• For patients with exercise-induced asthma, a short-acting bronchodilator should be used 15-30 minutes before exercise, and a gradual warm-up period should be included to reduce the risk of bronchoconstriction
• Exercise intensity, duration, and frequency should be adjusted based on the patient's tolerance and progress, with the goal of gradually increasing the workload over time to promote further adaptations

Monitoring Exercise Progress

Subjective and Objective Measures

• Regular monitoring during exercise is essential to ensure safety and effectiveness, and to modify the exercise prescription as needed based on the patient's response and progress
• Subjective measures, such as the Borg Rating of Perceived Exertion (RPE) scale and the modified Medical Research Council (mMRC) dyspnea scale, can be used to assess the patient's perceived effort and breathlessness
• Objective measures, such as heart rate, oxygen saturation (SpO2), and blood pressure, should be monitored to ensure that the patient remains within safe limits and to detect any adverse responses

Adjustments and Reassessment

• If a patient experiences persistent or worsening symptoms (excessive dyspnea, desaturation, chest pain), the exercise prescription should be modified or suspended until the underlying cause can be addressed
• Periodic reassessment of the patient's functional capacity and clinical status should be performed to ensure that the exercise prescription remains appropriate and effective over time
• Exercise intensity, duration, and frequency should be adjusted based on the patient's tolerance and progress, with the goal of gradually increasing the workload over time to promote further adaptations
