Individualized Aerobic and High Intensity Training for Asthmatic Children (16)

The results concerning the cardiovascular adaptations after high intensity training (Fig 3) show that the maximal heart rate increased in the training group, but the maximal 02 pulse decreased slightly. These data suggest the following: (1) a decrease of stroke volume mediated by decreasing myocardial contract-ibility; (2) a decrease of arteriovenous 02 difference, with the […]

Individualized Aerobic and High Intensity Training for Asthmatic Children (15)

Previous studies have shown that exercise of maximal intensity and 30-s duration (which corresponds approximately to the sprint time performed by the children during the high intensity training) requires essentially an anaerobic glycolysis contribution.’ Moreover, when several bouts of exercise are performed, an inhibition of glycogenolysis occurs at the third and fourth exercise bouts. Therefore, […]

Individualized Aerobic and High Intensity Training for Asthmatic Children (14)

We thus cannot rule out the possibility that a bias occurred in the effects of the different training programs. In addition, the interpretation of our results remains problematic because there have been no other studies carried out on maximal intensity exercise in asthmatic children. However, we can point out that asthmatics seem to respond in […]

Individualized Aerobic and High Intensity Training for Asthmatic Children (13)

A particularly interesting finding in this study is the increase in VTh (about 20 percent) because the ventilatory requirement, for the range intensities between the pretraining and posttraining VTh, is lower. It is now well established that the level of hyperventilation is a major determinant of exercise-induced broncho-spasm. Thus, we can argue that, beyond cardiorespiratory […]

Individualized Aerobic and High Intensity Training for Asthmatic Children (12)

This result probably indicates a decrease of airway resistance. We observed a nonsignificant improvement in maximal flows in the trained group and we can hypothesize that Vtbw/Ti was more sensitive for showing a decrease in airway resistance than the maximal flows. However, an alternative explanation may be proposed since Haas et al have shown that […]

Individualized Aerobic and High Intensity Training for Asthmatic Children (11)

Effects of Aerobic Training After aerobic training, we observed a marked increase of two cardiorespiratory fitness variables: maximum 02 uptake (Vo2max) and VTh. The increase of Vo2max agrees with several previous studies1(M315- but contrasts with others. The results of our study show that this discrepancy might be explained by the lack of training individualization. Training […]

In contrast, our study failed to demonstrate significant modifications in average baseline pulmonary function and clinical wellbeing was only partly affected. Clinical Benefit and Pulmonary Function Though clinical evolution was not a specific feature of this work, and it was impossible to characterize the specific effects of the different training programs (season lability) on the […]

Individualized Aerobic and High Intensity Training for Asthmatic Children (9)

Effects of High Intensity Training The Vo2max (Fig 1) remained unchanged after high intensity training. However, the difference between the two groups was still significant (p<0.01). Furthermore, no differences were observed after this training either in VEmax or in the ventilatory variables (Fig 2 and Table 3). buy birth control online The VTh (Fig 1) […]

Individualized Aerobic and High Intensity Training for Asthmatic Children (8)

Moreover, the parents pointed out that their children were sometimes able to prevent acute asthmatic attacks by practicing relaxation and breathing exercises; the children were also described as being less anxious than previously. These observations were unlinked to the intensity of training. flovent inhaler Time Course of Lung Function We observed no significant differences between […]

Individualized Aerobic and High Intensity Training for Asthmatic Children (7)

Clinical Benefit This was assessed by a questionnaire, administered orally, which focused on the evolution of wheezing attack frequency and any modifications observed by the parents. ventolin 100 mcg Statistical Analysis The values are reported as mean ± SEM. The data collected on entry were compared for homogeneity between the two groups, using an unpaired […]
