Research Focus:

As a researcher with significant training in exercise science and sleep medicine, Dr. Kline's research focuses on the use of physical activity as a nonpharmacologic/behavioral treatment for disturbed sleep and its health consequences, how poor sleep impacts exercise behavior, and how behavioral interventions such as exercise may reduce cardiometabolic disease risk through improved sleep. Dr. Kline also has a long-standing interest in studying the impact of sleep and circadian rhythms on athletic performance, and specifically how these factors may be used to optimize performance. He utilizes a wide variety of measurement techniques to assess sleep, including self-report questionnaire, diary, actigraphy, home-based portable monitoring, and laboratory-based polysomnography, and has addressed his research questions using a number of different approaches including laboratory-based randomized controlled trials (exercise and sleep apnea), archival analyses of RCTs (DREW, Sleep AHEAD) and epidemiologic datasets (SWAN), and observational surveys ('Sleep in America' poll).

Current Research:

Dr. Kline's research is currently supported by a Career Development Award from the NIH's National Heart, Lung, and Blood Institute. With this grant, he is studying the subclinical cardiovascular risk profile of the insomnia/short sleep phenotype and examining whether an augmented behavioral intervention would be feasible for this phenotype. Data collection is ongoing and will continue through December 2018. For more information on this study, visit www.pittsleepheartstudy.com.

Dr. Kline is also conducting a study on commercial sleep trackers (Fitbit, Garmin) and how well they measure sleep in comparison to research-grade sleep trackers. Data collection is ongoing and will continue through December 2017.

Finally, Dr. Kline recently received funding to address whether acute exercise impacts obstructive sleep apnea (OSA) severity and examine whether evening exercise reduces OSA severity to a greater extent than morning exercise in comparison with a sedentary control condition. The study is still in its planning stage, with data collection anticipated to begin in the fall of 2017.

If interested in learning more about any of these studies, please contact Dr. Kline.

Students:

Dr. Kline is looking to accept graduate students with research interests in the bidirectional relationship between exercise and sleep for the 2018-2019 academic year. Please contact Dr. Kline for additional information about the research group and the application process.

If you are an undergraduate or MS student at the University of Pittsburgh who is interested in joining the group as a volunteer research assistant, please contact Dr. Kline. The minimum commitment expected is 5-10 hours per week for at least 2 semesters. Students will gain hands-on experience at all stages of the research process.
