Control of Breathing During Exercise
Comprehensive Physiology, 2012Abstract During exercise by healthy mammals, alveolar ventilation and alveolar‐capillary diffusion increase in proportion to the increase in metabolic rate to prevent PaCO 2 from increasing and Pa o 2

Breathing exercises for adults with asthma
Cochrane Database of Systematic Reviews, 2013Breathing exercises have been widely used worldwide as a complementary therapy to the pharmacological treatment of people with asthma.To evaluate the evidence for the efficacy of breathing exercises in the management of patients with asthma.The search for trials led review authors to review the literature available in The Cochrane Library, MEDLINE ...

Control of breathing in the exercising dog
Respiration Physiology, 1971Abstract The ventilatory response to exercise was studied on awake dogs trained to run on a treadmill. Various combinations of speed and grade produced metabolic increases up to 6.5 times the resting value. Ventilatory flow, tidal volume and respiratory frequency were measured cycle by cycle for the purpose of analyzing the roles of nervous and ...

Oronasal breathing during exercise
Pfl�gers Archiv European Journal of Physiology, 1978The shift from nasal to oronasal breathing (ONBS) has been observed on 73 subjects with two independent methods. A first group of 63 subjects exercising on a bicycle ergometer at increasing work load (98--196 W) has been observed. On 35 subjects the highest value of ventilation attained with nasal breathing was 40.2 +/- 9.41 . min-1 S.D.

Influence of exercise hyperthermia on exercise breathing pattern
Journal of Applied Physiology, 1979Passive elevation of the body core temperature (Tc) induces rapid, shallow breathing in resting man. We wondered if exercise-induced Tc elevation would also lead to decreased tidal volume (VT) and increased breathing frequency (f) during exercise. To investigate this question, 10 subjects each performed 47 min of cycle ergometer exercise at 50--60% of

Breathing exercises for adults with asthma
Drug and Therapeutics Bulletin, 2015Asthma is a common long-term condition that remains poorly controlled in many people despite the availability of pharmacological interventions, evidence-based treatment guidelines and care pathways.1 There is considerable public interest in the use of non-pharmacological approaches for the treatment of asthma.2 A survey of people with asthma reported ...

Breath holding at beginning of exercise
Journal of Applied Physiology, 1962Men stood astride a moving treadmill belt and at a verbal signal held their breath, jumped on the treadmill belt, and walked or ran at a series of speeds up to 9 mph until the breaking point was reached. Breath-holding time decreased sharply with increasing exercise rates, but began to level off at approximately 30 sec between 6 and 9 mph.

Breathing exercises for dysfunctional breathing/hyperventilation syndrome in children
2013Dysfunctional breathing is described as chronic or recurrent changes in breathing pattern causing respiratory and non-respiratory symptoms. It is an umbrella term that encompasses hyperventilation syndrome and vocal cord dysfunction. Dysfunctional breathing affects 10% of the general population.
