Official title
Metabolic Effects of Interrupting Sedentary Time in Youth In-lab and in Free-living Settings
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This study is a randomized crossover trial to compare the effectiveness of interrupting SB on glucose homeostasis in the lab and free-living settings. All participants (N=56) will complete one screening visit to determine eligibility, complete at fitness test, and body composition analysis by bioelectrical impedance. After 7-21 days, all participants will complete two 3-hour in-lab oral glucose tolerance tests (spaced 7-21 days apart). Prior to the in-lab OGTT visits, participants will wear an activity monitor for 7 days on the right thigh. The experimental conditions for the OGTTs will be: 1) 3-hour OGTT of continuous sitting; and 2) 3-hour OGTT with sitting interrupted every 30 minutes with 3-minutes of moderate intensity walking on a treadmill. There will be a 7-21 day washout period between the OGTT visits. In addition, a subset of participants (N=12) who meet inclusion criteria and who successfully complete both OGTT visits will complete a second randomized crossover trial in the free-living environment. The experimental conditions for the free-living components will be: 1) 4 days of habitual sedentary behaviors; and 2) 4 days of prompted short exercise breaks during times in which sedentary behaviors have exceeded 30 minutes. Participants in the free-living trial will wear an activity monitor and a continuous glucose monitor.
