Oronasal breathing during exercise

Pfl�gers Archiv European Journal of Physiology, 1978
The 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.

Breathing exercises for asthma

2000
There is much anecdotal evidence in Eastern and Western literature describing considerable benefits for patients with asthma when treated with breathing interventions. The term 'breathing exercise, training and retraining' has numerous interpretations depending on the nature of the therapy, therapist and cultural background.To assess the evidence for ...

Breath Holding After Exercise

Journal of Applied Physiology, 1957
Breath holding time was measured after exercise at five grades of work in a group of 12 men. An average of 1.4 seconds elapsed between the signal, which was given without warning, and the cessation...

Control of Breathing During Exercise

Comprehensive Physiology, 2012
AbstractDuring exercise by healthy mammals, alveolar ventilation and alveolar‐capillary diffusion increase in proportion to the increase in metabolic rate to prevent PaCO2 from increasing and Pao2 from decreasing. There is no known mechanism capable of directly sensing the rate of gas exchange in the muscles or the lungs; thus, for over a century there

Qigong — Chinese Breathing Exercise

The American Journal of Chinese Medicine, 1982
Qigong is an ancient Chinese breathing exercise with meditation which is being developed today for therapy of chronic illnesses in the People's Republic of China. It is claimed to cure gastric ulcers, hypertension, anxiety neurosis, otitis media, cancer and has even been used as a form of anaesthesia.

Work of breathing in exercising ponies

Research in Veterinary Science, 1989
This paper attempts to evaluate the changes in the mechanical work of breathing induced by the increase of ventilation in ponies exercising on a treadmill. Airflow, tidal volume (VT) and oesophageal pressure were simultaneously recorded in eight ponies (four to six years old and weighing 258 +/- 11 kg) before, during and after standardised exercise ...

Influence of exercise hyperthermia on exercise breathing pattern

Journal of Applied Physiology, 1979
Passive 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 Easy: Exercise Despite Asthma

The Physician and Sportsmedicine, 1992
In brief More than 80% of asthmatic patients develop exercise-induced asthma (EIA), but most of them can successfully and safely participate in most types of physical activity. Physicians can teach them to avoid conditions that exacerbate EIA, such as air pollution.
