Effect of different conditioning methods of traditional Chinese health exercise on lung function in healthy middle-aged and elderly people: study protocol for a randomized controlled trial.

Background: Lung function is highly age-dependent as it decreases in varying degrees with age, even in healthy people. Decreased lung function results in less elastic lung tissue, reduced chest wall compliance, reduced area for gas exchange, and even a variety of chronic diseases. Traditional Chinese health exercise (TCHE) has three components: "breath regulation," "body regulation," and "heart regulation," which play an important role in the improvement of lung function.

Social support and HIV/STDs infections among a probability-based sample of rural married migrant women in Shandong Province, China.
