Other Considerations Be attentive to affective issues such as mood, motivation, frustration, and confusion. Correctly managing affective issues can favorably influence how a patient conducts, adheres to, and responds to a prescribed exercise regimen. Strategies aimed at minimizing negative influences due to these issues are helpful and include close supervision, individualized instruction until independence is established, involvement of family members, repetition of instructions, and alternate teaching methods. Early-onset local muscle and general fatigue are common and should be considered when setting work rates and rate of progression. Specificity of training can be employed for both aerobic and resistance training in an attempt to provide an individual with the strength and endurance needed to return to his or her previous occupation. Exercise training leads to an improved ability to perform physical work, an enhanced self-efficacy, and a greater desire and comfort level for returning to work following the illness (79,112). A list of respiratory diseases in which exercise is of potential benefit is shown in Box 9. Bronchiectasis — abnormal chronic enlargement of the airways with impaired mucus clearance Restrictive lung diseases — extrapulmonary respiratory diseases that interfere with normal lung expansion. Examples include the following: Interstitial lung disease/pulmonary fibrosis — scarring and thickening of the parenchyma of the lungs Pneumoconiosis — long-term exposure to dusts, especially asbestos Restrictive chest wall disease, (e. The conclusive evidence for exercise training as an effective therapy for asthma is lacking, and at present, there are no specific evidence-based guidelines for exercise training in these individuals. Some (32,47,101) but not all (94) systematic reviews and meta-analyses have suggested that exercise training can be beneficial for individuals with asthma. The data examined from these reviews are limited by small numbers of randomized controlled trials and heterogeneity of trial methods and subjects. Significant improvements in days without asthma symptoms, aerobic capacity, maximal work rate, exercise endurance, and pulmonary minute ventilation ( E) have been noted. Overall, exercise training is well tolerated and should be encouraged in people with stable asthma (32,39,84). Exercise Testing Assessment of physiologic function should include evaluations of cardiopulmonary capacity, pulmonary function (before and after exercise), and oxyhemoglobin saturation via noninvasive methods. Exercise testing is typically performed on a motor-driven treadmill or an electronically braked cycle ergometer. Immediate administration of nebulized bronchodilators with oxygen is usually successful for relief of bronchoconstriction (40). These tests should be administered by appropriately trained individuals with medical supervision. Evidence of oxyhemoglobin desaturation ≤80% should be used as test termination criteria in addition to standard criteria (9). Exercise Prescription Specific evidence-based exercise training guidelines for people with asthma are not available at this time. However, exercise training is generally well tolerated in individuals successfully managed with pharmacotherapy and when triggers to bronchoconstriction (e. Position statements on exercise in asthma (84) and systematic reviews (32) support this recommendation. Individuals experiencing exacerbations of their asthma should not exercise until symptoms and airway function have improved. Individuals on prolonged treatment with oral corticosteroids may experience peripheral muscle wasting and may benefit from resistance training. Exercise in cold environments or those with airborne allergens or pollutants should be limited to avoid triggering bronchoconstriction in susceptible individuals. Use of a nonchlorinated pool is preferable because this will be less likely to trigger an asthma event. Be aware of the possibility of asthma exacerbation shortly after exercise particularly in a high-allergen environment. This contributes to the loss of muscle strength, power, and endurance and decrements in the performance of everyday functional activities. The beneficial effects of exercise occur mainly through adaptations in the musculoskeletal and cardiovascular systems that in turn reduce stress on the pulmonary system during exercise (114). Patients should be given specific, standardized instructions on how to relate the wording on the scale to their level of breathlessness (13). Because dyspnea scales are subjective, some caution is advised in their interpretation as exercise intolerance may be accompanied by exaggerated dyspnea scores without corresponding physiological confirmation (37). In addition to standard termination criteria, exercise testing may be terminated because of severe arterial oxyhemoglobin desaturation (i. Walking protocols may be more suitable for individuals with severe disease who lack the muscle strength to overcome the increasing resistance of cycle leg ergometers. Arm ergometry may result in increased dyspnea that may limit the intensity and duration of the activity. Pulmonary diseases and their treatments affect both the lungs and skeletal muscles (i. Because muscle weakness and gait and balance abnormalities are among the risk factors for falling (125), lower extremity strengthening and balance training are effective countermeasures. Exercise Training Considerations Higher intensities yield greater physiologic benefits (e. Supervision at the outset of training allows guidance in correct execution of the exercise program, enhanced safety, and optimizing benefit (99). This may allow these patients to tolerate relatively high work rates that approach peak levels (106) and achieve significant training effects. Flexibility exercises may help overcome the effects of postural impairments that limit thoracic mobility and therefore lung function (117). Regardless of the prescribed exercise intensity, the exercise professional should closely monitor initial exercise sessions and adjust intensity and duration according to individual responses and tolerance. In many cases, the presence of symptoms, particularly dyspnea/breathlessness supersedes objective methods of Ex R. Maximizing pulmonary function using bronchodilators before exercise training in those with airflow limitation can reduce dyspnea and improve exercise tolerance (117). Supplemental oxygen is indicated for patients with a P O ≤55 mm Hg or ana 2 SaO ≤88% while breathing room air (2 100). In patients using ambulatory supplemental oxygen, flow rates will likely need to be increased during exercise to maintain SaO >88%. Although inconclusive, there is2 evidence to suggest the administration of supplemental oxygen to those who do not experience exercise-induced hypoxemia may lead to greater gains in exercise endurance particularly during high intensity exercise (87,106,117). Individuals suffering from acute exacerbations of their pulmonary disease should limit exercise until symptoms have subsided. However, these programs should be modified to include disease-specific strategies. Resistance exercise training may be added after the aerobic training is established and well tolerated.
