Interrupting Sitting Time During Postprandial State
A study testing 3-min Exercise Per 30 Min and 3-min Exercise Per 15 Min in people with Sedentary Behavior, run by Franklin Pierce University at 1 site in United States.
Trial summary
The literature has shown that interrupting sitting time with frequent physical activities (e.g., cycling on a stationary bike for 3 minutes every 30 minutes of sitting) is effective for decreasing blood sugar levels. However, the optimal frequency and distribution of sitting interruption remains less clear. Read more about this study

About this study
Official title: Redistributing Intermittent Physical Activity Breaks to Target Postprandial Glucose Excursion.
The literature has shown that interrupting sitting time with frequent physical activities (e.g., cycling on a stationary bike for 3 minutes every 30 minutes of sitting) is effective for decreasing blood sugar levels. However, the optimal frequency and distribution of sitting interruption remains less clear. The purpose of this study is to compare the effects of two different protocols of sitting interruption (i.e., 3 minutes of cycling every 30 minutes versus 3 minutes of cycling every 15 minutes) on blood sugar levels.
Read the detailed description
This study will involve two different physical activity conditions and a control condition. Each participant will undergo the three conditions in a random order. The first protocol involves 3 minutes of cycling on a stationary bike at moderate intensity every 30 minutes for 6 hours, totaling 36 minutes of cycling exercise. The second protocol involves 3 minutes of cycling on a stationary bike at moderate intensity every 15 minutes for 3 hours to match the total exercise duration in the first protocol. Participants will remain seated for 3 hours to match to the total time spent in the lab. For the control condition, participants will remain seated. For each condition, participants will be provided with two meals, one before the protocol and another one in the middle of the protocol. The meals will be purchased from the cafeteria on campus based on the participant's own choice as long as carbohydrates account for 55-65% of total calories. Participants will eat identical meals across the three conditions.

|---|---|---|
| 3-min Exercise Per 30 Min | Experimental | This protocol involves 3 minutes of cycling on a stationary bike at moderate intensity every 30 minutes for 6 hours, totaling 36 minutes of cycling exercise. Receives: Behavioral: 3-min Exercise Per 30 Min |
| 3-min Exercise Per 15 Min | Experimental | This protocol involves 3 minutes of cycling on a stationary bike at moderate intensity every 15 minutes for 3 hours to match the total exercise duration in the first protocol. Receives: Behavioral: 3-min Exercise Per 15 Min |

What is being measured
The primary outcome is the main question the study is designed to answer.
Postprandial glucose levels
The investigators will measure capillary blood sugar levels every 30 minutes using the finger-stick method.
Measured: three and a half hour after the carbohydrates intake

Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 24 Nov 2020. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Postprandial glucose levels (time frame: three and a half hour after the carbohydrates intake). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 24 Nov 2020; AzTrials last refreshed its copy on 27 Oct 2026.
