Interstitial lung disease (ILD) is characterised by exertional dyspnoea, exercise limitation and reduced quality of life. The role of exercise training in this diverse patient group is unclear. The aims of this study were to establish the safety of exercise training in ILD; its effects on exercise capacity, dyspnoea and quality of life; and whether patients with idiopathic pulmonary fibrosis (IPF) had similar responses to those with other types of ILD.
                57 subjects with ILD (34 IPF) were randomised to receive 8 weeks of supervised exercise training or weekly telephone support. The 6 min walk distance (6MWD), incremental exercise test, modified Medical Research Council (MRC) dyspnoea score and Chronic Respiratory Disease Questionnaire (CRDQ) were performed at baseline, following intervention and at 6 months.
                80% of subjects completed the exercise programme and no adverse events were recorded. The 6MWD increased following training (mean difference to control 35 m, 95% CI 6 to 64 m). A significant reduction in MRC score was observed (0.7 points, 95% CI 0.1 to 1.3) along with improvements in dyspnoea (p = 0.04) and fatigue (p<0.01) on the CRDQ. There was no change in peak oxygen uptake; however, exercise training reduced heart rate at maximum isoworkload (p = 0.01). There were no significant differences in response between those with and without IPF. After 6 months there were no differences between the training and control group for any outcome variable.
                Exercise training improves exercise capacity and symptoms in patients with ILD, but these benefits are not sustained 6 months following intervention. Although pulmonary rehabilitation is effective for patients with COPD, its efficacy in patients with IPF is unknown. The purpose of this study was to evaluate the effects of pulmonary rehabilitation in IPF.
                Thirty patients diagnosed with IPF, according to the consensus statement, were randomly assigned to the rehabilitation group or the control group. The pulmonary rehabilitation mainly consisted of a 10-week programme of exercise training. Pulmonary function, blood gas analysis, 6MWD, dyspnoea rating with the baseline dyspnoea index and health-related quality of life score on the St George's Respiratory Questionnaire were evaluated at baseline and after the programme.
                Assessment of efficacy was carried out on 13 patients who completed the programme and 15 patients in the control group. There were no significant effects of the programme on measures of pulmonary function, values of arterial blood gas analysis or dyspnoea rating. Although there were some differences in the baseline 6MWD and total health-related quality of life score which were not statistically significant, marked improvements were observed in the 6MWD (mean difference 46.3 m (95% CI: 8.3-84.4), P < 0.05) and the total health-related quality of life score (-6.1 (95% CI: -11.7 to -0.5), P < 0.05).
                Pulmonary rehabilitation improves both exercise capacity and health-related quality of life in patients with IPF. To evaluate the effects of an aquatic training programme for JIA patients.
                Fifty-four patients with JIA (age range 5 to 13 yr) participated in this study and were randomized into an experimental (n = 27) and a control (n = 27) group. The children in the experimental group received a training programme consisting of a 1 h per week supervised training programme in a local pool of approximately 20 sessions. Effects were analysed on the following domains: functional ability, health-related quality of life, joint status and physical fitness.
                Although all measures improved more in the experimental group than the control group, none of the differences was statistically significant.
                The current research found no significant effect of an aquatic fitness training programme in children with JIA. Since there were no signs of worsening in health status, one can conclude that this was a safe exercise programme. Regular physical activity may improve different aspects of wellbeing in older people, such as quality of life, vitality and depression. However, there is little experimental evidence to support this assumption. Therefore, we examined the effect of different training protocols on quality of life, vitality and depression of older adults living in long-term care facilities.
                Subjects (n = 173, aged 64 to 94 years, living in long-term care facilities), were randomized to six months of three different moderate-intensity group exercise training protocols, or to an 'educational' control condition. Exercise consisted of two 45-60-minute training sessions per week of 1) resistance training; 2) all-round, functional training; or 3) a combination of both. Perceived health, the Geriatric Depression Scale (GDS), the Vitality Plus Scale (VPS) and the Dementia Quality of Life questionnaire (DQoL) were administered at baseline and after six months.
                In the combined training group a small but significant decline was seen in perceived health, DQoL and VPS score compared to the control group.
                We conclude that neither strength training nor all-round, functional training of moderate intensity is effective in improving quality of life, vitality or depression of older people living in long-term care facilities. This study evaluated long-term effects of 12 weeks of supervised training, of at least 45 minutes duration with two sessions per week, on physical performance and psychological well-being after myocardial infarction (MI). Sixty-nine patients were randomized to either an exercise or a nonexercise group. Maximum exercise capacity 6 weeks post-MI was inversely related to the acute peak aspartate aminotransferase values in serum, as an index of infarct size. One year post-MI, the increase in level of fitness (10%) in the training group did not significantly exceed (p = .10) that of the controls (2%). No intergroup differences were registered in self-rated psychological well-being and physical scores or in the return to work rate. In the training group, but not in the controls, the change in perceived dyspnoea at leisure-time activities was positively related to the objectively measured peak exercise capacity. We conclude that after MI only marginal improvements in physical performance are achieved 6 months after training is finished, with no long-term psychological benefits apparent versus a usual care program. The adaptive implications of supervised conventional exercise programs post-MI are therefore questioned. To evaluate the efficacy of supervised high-intensity progressive resistance training (PRT) on lower extremity strength, function, and disability in older, long-term stroke survivors.
                Forty-two volunteers aged 50 years and above, 6 months to 6 years after a single mild to moderate stroke, were randomized into either a control group of upper extremity stretching or a PRT group that received a 12-week supervised high-intensity resistance training program consisting of bilateral leg press (LP), unilateral paretic and nonparetic knee extension (KE), ankle dorsiflexion (DF), and plantarflexion (PF) exercises. Functional performance was assessed using the 6-minute walk, stair-climb time, repeated chair-rise time, and habitual and maximal gait velocities. Self-reported changes in function and disability were evaluated using the Late Life Function and Disability Instrument (LLFDI).
                Single-repetition maximum strength significantly improved in the PRT group for LP (16.2%), paretic KE (31.4%), and nonparetic KE (38.2%) with no change in the control group. Paretic ankle DF (66.7% versus -24.0%), paretic ankle PF (35.5% versus -20.3%), and nonparetic ankle PF (14.7% versus -13.8%) significantly improved in the PRT group compared with the control. The PRT group showed significant improvement in self-reported function and disability with no change in the control. There was no significant difference between groups for any performance-based measure of function.
                High-intensity PRT improves both paretic and nonparetic lower extremity strength after stroke, and results in reductions in functional limitations and disability. Beneficial training outcomes have been reported in patients with chronic heart failure (CHF) following leg exercise training. However, data from more comprehensive training programs are limited. The aim of this study was to test the hypothesis that exercise training applying the concept of comprehensive local muscle training can improve aerobic and functional working capacity as well as quality of life in patients with CHF.
                Twenty-four men and women [age 63+/-9 years (mean+/-S.D.)] with stable, moderate chronic heart failure (left ventricular ejection fraction 30+/-10%), were investigated in a randomized controlled study with a training group of 16 patients and a control group of 8 patients. The training was performed as an aerobic resistance training by activating all the main muscle groups, one at a time. The patients exercised for 1 h, three times per week for 8 weeks.
                Patient groups did not differ at baseline. Peak oxygen uptake (8%, P<0.03), the distance walked in a 6-min walking test (11%, P<0.002), the health-related quality of life (P<0.001) and plasma norepinephrine levels at rest (32%, P<0.003) and at submaximal intensities (P<0.03) improved after training. No changes were found in the control group, except for decreased peak oxygen uptake (P<0.02) and quality of life scores (P<0.03).
                Since comprehensive physical training activating a minor muscle mass at a time markedly improves exercise capacity and quality of life and reduces catecholamine levels, it can be recommended for the rehabilitation of patients with CHF under supervision of a physical therapist. Twenty-four men with chronic bronchitis participated in a controlled trial of a physical training scheme. The training involved progressive stair-climbing exercises carried out over a three-month period unsupervised at home. The twelve men in the exercise group benefited significantly in terms of general well-being and reduced breathlessness. Their exercise tolerance increased significantly as judged by increased walking speed in a simple 12-minute walking test and by a greater work load tolerated in a progressive work load test on a bicycle ergometer. The mean stride length during the walking test increased significantly with training. No significant changes occurred in body weight, ventilatory function tests or heart rate on exercise. There were no important changes in the control group. It is not clear whether the improvements noted were due to physiological changes such as improved neuromuscular coordination producing a more efficient walking pattern or to predominantly psychological factors such as increased tolerance of dyspnoea. The study demonstrates that a simple training scheme which can be administered from a hospital clinic or family doctor's surgery is safe, feasible, and of benefit to the chronic bronchitic. This study investigated the relative effects of distributed constraint-induced therapy (CIT) and bilateral arm training (BAT) on motor performance, daily function, functional use of the affected arm, and quality of life in patients with hemiparetic stroke.
                A total of 60 patients were randomized to distributed CIT, BAT, or a control intervention of less specific but active therapy. Each group received intensive training for 2 hours/day, 5 days/week, for 3 weeks. Pretreatment and posttreatment measures included the Fugl-Meyer Assessment (FMA), Functional Independence Measure (FIM), Motor Activity Log (MAL), and Stroke Impact Scale (SIS). The proximal and distal scores of FMA were used to examine separate upper limb (UL) elements of movement.
                The distributed CIT and BAT groups showed better performance in the overall and the distal part score of the FMA than the control group. The BAT group exhibited greater gains in the proximal part score of the FMA than the distributed CIT and control groups. Enhanced performance was found for the distributed CIT group in the MAL, the subtest of locomotion in the FIM, and certain domains of the SIS (eg, ADL/IADL).
                BAT may uniquely improve proximal UL motor impairment. In contrast, distributed CIT may produce greater functional gains for the affected UL in subjects with mild to moderate chronic hemiparesis.
Physical training is safe for people with ILD. Improvements in functional exercise capacity, dyspnoea and quality of life are seen immediately following training, with benefits also evident in IPF. There is little evidence regarding longer-term effects of physical training.
