The Effect of High-Intensity Short-Duration Exercise Versus Moderate-Intensity High-Volume Exercise on Glucose Control

2026年9月14日 更新者：University of California, San Francisco

The Effect of High-Intensity Short-Duration Exercise Versus Moderate-Intensity High-Volume Exercise on Glucose Control as Measured by Continuous Glucose Monitoring

This study will be conducted as a prospective, randomized crossover trial evaluating non-diabetic and pre-diabetic adults ($n=12$) continuously monitored with Dexcom G7 continuous glucose monitors over an 11-day period. Participants will complete two distinct exercise protocols in a randomized sequence: five consecutive days of Zone 2 aerobic exercise and a single session of high-intensity interval training (HIIT). Primary outcome metrics will focus on mean glucose levels and time in range (TIR, defined as $\le 120\text{ mg/dL}$) recorded throughout each active exercise block and its associated recovery window. To evaluate the comparative efficacy of the two modalities, paired within-subject differences will be statistically analyzed against pre-specified non-inferiority margins set at $3\text{ mg/dL}$ for mean glucose, as well as a primary $3$-point and secondary $5$-point margin for time in range.

描述

Inclusion Criteria:

Age 18 years or older. Non-diabetic or pre-diabetic status (defined by medical history or standard screening criteria, e.g., HbA1c < 6.5%).

Capable and willing to participate in both Zone 2 aerobic exercise and high-intensity interval training (HIIT) protocols.

Willing to wear a continuous glucose monitor (Dexcom G7) continuously for the 11-day study duration.

Able to provide written informed consent.

Exclusion Criteria:

Diagnosis of Type 1 or Type 2 diabetes. Use of glucose-lowering medications, insulin, or other pharmaceuticals that significantly alter glucose metabolism.

Current skin conditions, allergies, or sensitivities to medical-grade adhesives that prevent continuous glucose monitor placement.

Musculoskeletal, cardiovascular, or neurological conditions that contraindicate vigorous exercise or high-intensity interval training.

Pregnant or planning to become pregnant during the study period. Concurrent participation in another clinical trial or interventional exercise study.

武器和干预

参与者组/臂
干预/治疗
实验性的：Moderate Intensity Exercise
Five consecutive days of moderate intensity aerobic exercise
其他：Moderate Intensity aerobic training
45 minutes of zone 2 training for five consecutive days
有源比较器：High Intensity Exercise
One session High-Intensity Interval training
其他：High Intensity Interval Training
The Norwegian 4x4: The workout begins with a 5-to-10-minute warm-up, followed by four separate 4-minute high-intensity intervals where you push your body to 85%-95% of your maximum heart rate (roughly an 8 or 9 out of 10 effort level, where you are breathing too heavily to speak full sentences). Each intense "push" is interspersed with a 3-minute active recovery period of low-intensity movement-such as walking or light cycling-to let your heart rate drop back down to roughly 60%-70% of its maximum before starting the next round.
