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 ...

Regulation of Breathing at Beginning of Exercise

Journal of Occupational and Environmental Medicine, 1963
In initial 20-sec periods of running on the treadmill, raising the slope to 12% increased by 50% the integrated muscle action potential, recorded from the under side of the thigh, without affecting the ventilation in four men. Five men worked for 1 min at four tasks, two on the treadmill and two on the horizontal cycle ergometer.

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 ...

Breathing during Exercise

New England Journal of Medicine, 1978
THE main source of energy for the life process is the oxidation of dietary substrate in the mitochondria of cells, and the major catabolic end product is carbon dioxide.

Potassium and Breathing in Exercise

Sports Medicine, 1997
The increase in ventilation caused by exercise is controlled by a combination of neural and chemical events, although the precise contribution and relative importance of these signals is still debated. It is generally agreed that the genesis of exercise hyperpnoea lies within the central nervous system and that peripheral reflexes, both chemical and ...

Control of Breathing During Exercise

Comprehensive Physiology, 2012
Abstract 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, 2013
Breathing 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 ...

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.

Control of breathing in the exercising dog

Respiration Physiology, 1971
Abstract 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 ...

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
