In view of the lack of objective information on work performance in asthma, a progressive incremental exercise test was carried out in 44 subjects with mild to moderate asthma and 64 normal, healthy subjects matched for habitual activity, to compare cardiorespiratory fitness and to determine the relative contribution of airflow obstruction to exercise limitation. The two groups achieved similar maximum heart rates (mean (SD) 176(12) and 175(10) beats/min). After allowance for confounding… 

Exercise performance in children with asthma: is it different from that of healthy controls?

The results suggest that asthmatic children can achieve a level of exercise performance similar to that of healthy children, provided that they have a comparable level of habitual physical activity.

Maximal oxygen consumption in asthma patients before and after aerobic training program

A long-term aerobic exercise intervention can induce favorable changes in cardiorespiratory fitness in adult males with mild to moderate asthma.

Physiologic and nonphysiologic determinants of aerobic fitness in mild to moderate asthma.

Results from the exercise questionnaire suggested that asthmatics perceive their disease as a limiting factor to improved aerobic fitness and that they lack adequate knowledge about asthma and exercise.

Aerobic conditioning in mild asthma decreases the hyperpnea of exercise and improves exercise and ventilatory capacity.

Exercise rehabilitation improves aerobic fitness in both asthmatic and nonasthmatic participants of a 10-week aerobic fitness program and additional benefits of improved ventilatory capacity and decreased hyperpnea of exercise occurred in patients with mild asthma.

The Relationship Between Physical Work Capacity and Asthma Disease

PWC was correlated with different degrees of asthma, and asthma disease was an important factor impressing PWC.

Relationship of Cardiorespiratory Fitness with Spirometrical markers in Asthma patients

It is suggest that increased aerobic capacity by exerc ise training can be respiratory function in asthma patients.

Cardiopulmonary responses of asthmatic children to exercise: Analysis of systolic and diastolic cardiac function

The data suggest that most of these children with moderate or severe asthma have normal diastolic cardiac function, but exhibit impaired systolic function and have lower LVM than healthy peers of the same age.

Exercise training on disease control and quality of life in asthmatic children.

Supervised exercise training might be associated with beneficial effects on disease control and quality of life in asthmatic children, and an adjunct role of physical conditioning on clinical management of patients with more advanced disease is suggested.

Cardiopulmonary fitness in children with asthma versus healthy children

Cardiopulmonary fitness in children with asthma was moderately but significantly altered compared with healthy children and a decreased VO2max was associated with female gender, high BMI and the pulmonary function.

Maximal oxygen consumption rate in patients with bronchial asthma-the effect of beta 2-adrenoreceptor stimulation.

It is concluded, that Vo2 max seems to be within the normal range in asthmatics, provided they are free from attacks, and normal relationships were observed between Vo2 and work load, ventilation, RPE and acid-base data and these relations were unaffected of beta 2-stimulation.

Specificity of Exercise in Exercise-induced Asthma

Swimming should be recommended in preference to running or cycling as an exercise programme for adults and children with asthma, and the unexplained aetiology of increased airways resistance after exercise in asthmatics is discussed.

Exercise conditioning in children with asthma.

Children with asthma can safely engage in a running program and can increase work tolerance and fitness without worsening their asthma.

Ventilatory muscle strength and endurance training.

It is concluded that ventilatory muscle strength or endurance can be specifically increased by appropriate ventilatories muscle training programs.

Physical Education Programs and Exercise-Induced Asthma

It is shown that asthma, with or without hay fever, was the third main cause of limitation of activity caused by chronic disease in persons under age 45.

Anaerobic threshold and respiratory gas exchange during exercise.

The I-min incremental work rate test is associated with changes in gas exchange which can be used as sensitive on-line indicators of the AT, thus bypassing the need for measuring arterial lactate or acid-base parameters to indicate anaerobiosis.

Metabolic responses to selective β-adrenergic stimulation in man

The responses of plasma free fatty acid, glucose, lactate, insulin and growth hormone to intravenous administration of the predominantly β-2 stimulant, salbutamol, were studied and tentative proposals are made regarding the nature of the β-receptor subtypes responsible for mediating these effects.

The metabolic effects of inhaled salbutamol.

It is concluded that inhaled salbutamol does not cause the unwanted metabolic effects reported with oral or parenteral administration, and that this is a further indication for this route of administration.
