Responses of healthy young males to fine-particle exposure are modified by exercise habits: a panel study.

ABSTRACT:

Background

Aerobic exercise benefits health but increases inhalation of fine particles (PM_2.5) in ambient air. Acute cardiopulmonary responses to PM_2.5 exposure in individuals with different exercise habits, especially in areas with severe air pollution, are not well understood.

Methods

To examine acute cardiopulmonary responses to PM_2.5 exposure modified by exercise habits, a panel of 20 healthy non-smoking male subjects, recruited in Beijing, China, completed seven visits. The exercise frequency per week and preferred exercise place were recorded using a baseline questionnaire to describe exercise habits. Fractional exhaled nitric oxide (FeNO), cytokines in exhaled breath condensate, blood pressure, and pulse-wave analysis (PWA) indices wer
