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 the previous studies was the same for all the subjects, and it is possible that some subjects could have been either insufficiently or too much stimulated. buy cipro
Aerobic training appears to have increased VrBWmax and VTBVV/Rmax in our training group, with a subsequent rise of VEmax. Ramonatxo et al have suggested that children with moderate asthma have good neural compensation of their resistive load by using higher Vtbw and lower respiratory frequencies, probably in order to avoid exaggerated turbulence. A complementary study carried out with more obstructed asthmatics has shown that this adaptation could reach a limit, these asthmatics being unable to increase sufficiently their Vtbw during an incremental exercise test. In this study, after the training period, the Vtbw values were the same as those reported by Ramonatxo et al, indicating a better ventilatory adaptation. After aerobic training, Vtbw/I1 was significantly increased at maximal exercise but also for the same metabolic rate (ie, at the same Vo2), thus, presumably for the same neural drive.
