Use of acetylene breathing to determine cardiac output in young and older adults

Article Abstract:

The reproducibility of open-circuit acetylene breathing, for measuring Qc during submaximal and near maximal exercise in young and older adults is examined. The estimates of Qc from open-circuit acetylene breathing are compared with previous established closed-circuit acetylene breathing.

Exercise training and autonomic nervous system activity in obese individuals

Article Abstract:

A study of obese men and women showed that not only did regular aerobic activity reduce body mass, it also increased the activity of the autonomic, sympathetic and parasympathetic nervous systems. This also increases body heat regulation and metabolism, increasing weight loss.
