WebJan 1, 1991 · The respiratory mechanics together with the rate of work of breathing were studied in five healthy adult Standardbred horses at rest and during different levels of exercise on a treadmill (0.8–2.3 ms −1, 7% slope). In three of the horses the stride frequency was also determined. WebThe ventilatory response to exercise is largely unaffected by μG. Maximum oxygen consumption seems to be maintained in short-duration flights (9–14 days) suggesting no pulmonary limitation to exercise. However, there is an abrupt reduction in peak upon return from short-duration space flight of ∼22%. The response returns to preflight ...
