“…The spirometric variables, which mainly reflect the function of the upper airways, showed a slight tendency toward improved FVC values at the end of the study (Table 2). Previous short-term training studies have shown minor effects (3,10) or significant improvements (15,16) of lung function tests. The latter studies involved patients with more advanced lung disease and sputum production.…”

“…3 Standardized exercise protocols of running or swimming have been shown to have beneficial effects on sputum clearance, lung function, muscle strength, aerobic endurance, and psychosocial behavior. [4][5][6][7][8] It has also been demonstrated that physical exercise is as effective in mobilizing bronchial secretions as chest physiotherapy. 9 In CF patients exercise tolerance is dependent on a variety of factors including the severity of the disease, nutritional status, the degree of airway obstruction, and hypoxemia.…”

Summary. Physical exercise can improve sputum clearance in patients with cystic fibrosis (CF). To set up individual training protocols it is desirable to know the anaerobic threshold (AT). Established methods such as blood lactate measurements and ergometry can only be performed in specialized centers. Conconi showed that the heart rate threshold (HRT), i.e., the deflection point from the linear relationship between work load and heart rate, correlated significantly with the AT in healthy adults. To assess the reliability of the HRT in CF, we performed ergometry in 32 CF patients (mean age, 21.0 ± 5.5 years; mean Shwachman score, 77.8 ± 12.0) according to the Conconi protocol. The HRT was compared with the aerobic threshold (AeT) as determined by the V-slope method and with two turn points in the lactate performance curve (LTP 1 , LTP 2 ).An HRT could be obtained in only 17 of the 32 patients (53%). In these 17 patients there was a significant correlation between HRT and the other thresholds, but the absolute values for the AT differed considerably: The mean HRT was 132% higher than the AeT according to Beaver, 107% higher than LTP 1 , and 19% higher than LTP 2 . Exercise protocols that rely solely on the HRT in CF will lead to excessive exertion during exercise training programs in these patients. According to these results the HRT of Conconi is not a suitable method to determine appropriate exercise levels in CF training programs and might even be harmful in CF patients. These results also indicate the need to test the reliability of a diagnostic procedure that has been developed only for healthy people.

“…Nutritional status and exercise tolerance in CF patients are associated with prognosis and survival [1,2], and their preservation is thus important [3]. Exercise programmes have been shown to improve exercise tolerance in children and adults with CF [4][5][6][7][8][9][10][11][12]. For monitoring of exercise programmes in individual patients, easy and reliable measurements of exercise capacity with correction for nutritional status are needed.…”

In children with cystic fibrosis, objective parameters of exercise tolerance are needed which are easy to measure in nonspecialized centres. We investigated maximal workload (W 'max) in children with cystic fibrosis in relation to body weight and fat-free mass, and compared this with results for maximal oxygen consumption (V 'O 2 ,max).Fourteen patients with cystic fibrosis performed an incremental maximal exercise test on a bicycle ergometer. W 'max, V 'O 2 ,max, body weight and fat-free mass were measured.W 'max and V 'O 2 ,max were significantly correlated (r=0.91; p<0.001). Using standard deviation scores in relation to reference values, W 'max and V 'O 2 ,max per kilogram body weight were significantly higher than uncorrected W 'max and V 'O 2 ,max (mean difference (95% CI) 0.63 (0.24-1.01) and 0.91 (0.32-1.49) SD units, respectively). There was no such difference after correction for fat-free mass. Standardized V 'O 2 ,max was significantly higher than standardized W 'max (mean difference (95% CI): 1.59 (1.14-2.04)), also after correction for body weight and fat-free mass.In children with mild-to-moderate cystic fibrosis, maximal workload per kilogram fat-free mass, but not per kilogram body weight, is a useful parameter to correct for diminished nutritional status. In these patients, maximal workload is consistently lower than maximal oxygen consumption. Taking into account this difference, maximal workload and maximal workload per kilogram fat-free mass can be used for follow-up of paediatric patients with cystic fibrosis in nonspecialized settings.
