单词 | hyperpnea |
例句 | Interestingly, exercise does not cause hyperpnea as one might think. Anatomy and Physiology 2013-06-19T00:00:00Z The exact mechanisms behind exercise hyperpnea are not well understood, and some hypotheses are somewhat controversial. Anatomy and Physiology 2013-06-19T00:00:00Z In contrast, forced breathing, also known as hyperpnea, is a mode of breathing that can occur during exercise or actions that require the active manipulation of breathing, such as singing. Anatomy and Physiology 2013-06-19T00:00:00Z However, hyperpnea during exercise appears to occur before a drop in oxygen levels within the muscles can occur. Anatomy and Physiology 2013-06-19T00:00:00Z As a result, hyperpnea related to exercise is initiated when exercise begins, as opposed to when tissue oxygen demand actually increases. Anatomy and Physiology 2013-06-19T00:00:00Z Therefore, hyperpnea must be driven by other mechanisms, either instead of or in addition to a drop in oxygen levels.
