Effects of walking on peak expiratory flow rate in four asthmatic children
1Department of Physical Education, University of North Carolina, School of Health, Greensboro 27412.
Abstract:
The effect of walking on peak expiratory flow rate (PEFR) of four asthmatic children is reported. Subjects 1 and 2 exercised three days per week and Subjects 3 and 4 exercised two days per week during this 9-mo. study. Subjects 1 and 3 exercised for 10 wk., did not exercise for 11 wk., and exercised again for 11 wk. Subjects 2 and 4 did not exercise for 10 wk., exercised for 11 wk., and again did not exercise for 11 wk. Subjects 1, 2, and 4 had a higher mean PEFR during exercise than during no exercise, and Subject 3 had a lower mean PEFR during exercise than during no exercise. These results suggest that walking may positively influence PEFR of selected asthmatic children if factors such as environment, allergies, and medication side-effects can be controlled.

Alveolar Surface Tension
The alveolar fluid lines the luminal surface of the alveoli and exerts a force called surface tension. This force is caused by the polar water molecules in the liquid being more strongly attracted to each...

Pulmonary Function Tests
Pulmonary Function Tests are crucial diagnostic tools for assessing respiratory function, particularly in patients with chronic respiratory disorders. They comprehensively evaluate lung volumes, ventilatory function, breathing mechanics, diffusion, and gas exchange. These tests help diagnose pulmonary diseases and play a significant role in monitoring disease progression, evaluating disability, and assessing response to therapy.
