Short-term physical training in bronchial asthma. Cardiorespiratory fitness evaluation by the shuttle test in asthmatic subjects during aerobic training. Deep diaphragmatic breathing: rehabilitation exercises for the asthmatic patient. Effect of Physiotherapy in Asthmatic Children–A One‐year Follow‐up after Physical Training Once a Week A short exercise and living course for asthmatics.
The effect of two types of physical training on patients with perennial asthma were compared in a blind , controlled , r and omized study . Eleven of 27 adults with asthma performed a physical training programme which did not change their oxygen consumption ( control group ) . The remaining 16 asthmatics performed a physical training programme which improved their maximal oxygen consumption ( training group ) . Both of the training programmes were performed for 1 hour , twice a week during a period of 2 months . No complications were reported during the performance of the training programmes . The doses of all medicines apart from beta 2-agonist aerosol were unchanged during the training period . The patients inhaled beta 2-agonist aerosol if their peak expiratory flow ( PEF ) was less than 60 % of their maximal PEF . The training group decreased their use of aerosol from an average of 4.94 puffs per day to 3.41 puffs per day ( P less than 0.05 ) . The control group did not change their use of beta 2-agonist aerosol significantly . It is concluded that physical exercise which improves the maximal oxygen consumption decreases the use of beta 2-agonist spray and that heavy exercise is well tolerated by asthmatics PURPOSE The purpose of this study was to assess the validity of the 20-m shuttle test with 1-min stages ( 20-MST ) to estimate maximal oxygen uptake ( VO2 max ) and its ability to register cardiorespiratory modifications over the course of an individualized aerobic training program for mild to moderately asthmatic children acclimatized to moderate altitude . METHODS Forty-eight asthmatic subjects aged 12 to 17 years performed both a maximal incremental exercise test on a cycle ergometer and the 20-MST . Ten of the subjects were then r and omly chosen and trained three times per week at their ventilatory threshold ( Vth ) intensity level for three months . Another group of ten asthmatic subjects served as control subjects . Training intensity was adjusted monthly ; heart rate values at Vth were increased by the same proportion as the increase in Vo2 max as measured by the 20-MST . At the end of training , both groups were again evaluated with the two tests . The Vo2 max values by direct measurement and by the 20-MST were not significantly different for the entire population ( 46.5 + /- 1.6 vs 47.2 + /- 2.1 ml.min-1.kg-1 ) . In addition , the two test results were in close agreement ( r = 0.84 ; p < 0.01 ) . After training , a sharp improvement in the direct Vo2 max ( 44.1 + /- 2.4 to 51.2 + /- 1.9 ml.min-1.kg-1 ) was noted in the training group as well as an increase in the Vth ( 25.6 + /- 1.9 to 32.1 + /- 3.4 ml.min-1.kg-1 ) , the maximal power ( 152 + /- 7.1 to 185 + /- 3.8 W ) , and the maximal oxygen pulse ( 0.24 + /- 0.007 to 0.27 + /- 0.008 ml.beat-1.kg-1 ) . CONCLUSION The indirect measure confirmed these results : a simultaneous increase in VO2 max ( 43.7 + /- 2.5 to 53.8 + /- 2.1 ml.min-1.kg-1 ) , maximal oxygen pulse ( 0.22 + /- 0.004 to 0.27 + /- 0.006 ml.beat-1.kg-1 ) , and the number of stages completed ( 7 + /- 1.4 to 10.1 + /- 1.3 ) was observed . It was concluded that the 20-MST has sufficient validity to assess VO2 max and to register cardiorespiratory modifications over the course of individualized aerobic training programs in mild and moderately asthmatic children . It thus may be used to adjust training intensities during these programs A new diaphragmatic breathing technique practice d without the aid of a physical corset is outlined , and the findings from a study of its application in the respiratory rehabilitation of asthmatic patients are presented . Sixty-seven asthmatic adults r and omly assigned to either deep diaphragmatic breathing training , physical exercise training , or a waiting list control group participated in a 16-week program . Deep diaphragmatic training result ed in significant reductions in medication use and in the intensity of asthmatic symptoms . Importantly , a nearly 300 % increase in time spent in physical activities also result ed from deep diaphragmatic training . A follow-up at two months found many patients had returned to earlier medication levels and sedentary habits . A strengthened musculature can replace the need for a physical aid in this respiratory habilitation ; adherence to its use may require individually-tailored encouragement Physiotherapy is an established treatment in asthmatic children . One purpose is to increase tolerance towards physical activity , decrease broncho-obstruction and promote elimination of secretions . A positive effect of physical training in asthmatic children has been reported in many studies . An improved working capacity has e.g. been shown after supervised physical training at least twice a week for a period of three months ( 1 ) . This was not a realistic level of training intensity in our clinical practice . Therefore , the goal of this study was to test whether physiotherapy combined with physical training once a week had any effect on working capacity or lung function tests in asthmatic children A 5-day , non-residential exercise and living course for children with asthma is described as a feature of a programme of outpatient physiotherapy .  Eleven children undertaking such a course were compared with 10 asthmatic children in a control group . The subject group showed , in the short term at least , an improvement in bronchial lability , peak flow rates , nocturnal and daytime wheeze , and activity compared with the controls . These findings were statistically significant . There was no difference between the groups in the number of days on which extra medication was taken . A short , sharp course is of benefit physically , socially and psychologically to children with asthma
OBJECTIVES To assess the evidence for the effects of physical training on pulmonary function , symptoms , cardiopulmonary fitness , and quality of life in subjects with asthma .
