简要总结
Physical inactivity and prolonged sedentary behavior are major health concerns, especially for individuals with chronic conditions such as diabetes and prediabetes. Many patients have difficulty following traditional exercise recommendations due to time constraints, limited physical capacity, comorbidities, or lack of access to exercise facilities. Therefore, new and more practical exercise strategies are needed.
"Exercise Snacks" is a novel physical activity approach that involves short bouts of exercise performed multiple times throughout the day. Each session is brief and easy to integrate into daily life, such as performing short periods of resistance exercises, brisk walking, stair climbing, or other simple activities. This approach may improve exercise adherence and provide health benefits without requiring long exercise sessions.
The purpose of this study is to evaluate the feasibility and acceptability of an Exercise Snacks intervention in sedentary adults with diabetes or prediabetes and to explore its potential effects on cardiovascular and metabolic health, physical function, and body composition.
In this study, sedentary adults aged 18-65 years with diabetes or prediabetes will participate in a 12-week study and will be randomly assigned to either an Exercise Snacks group or a control group. Participants in the Exercise Snacks group will perform short exercise sessions lasting approximately 3-5 minutes, including simple resistance exercises and short aerobic activities. These exercise sessions will be performed several times per day and integrated into daily routines. The control group will maintain their usual lifestyle without additional exercise intervention.
Participants may use wearable devices or mobile applications to receive reminders and record exercise activity. Assessments will be conducted before and after the intervention to evaluate physical activity adherence, physical function, body composition, blood pressure, blood glucose, and other cardiovascular and metabolic health indicators.
This study aims to determine whether short, frequent exercise sessions are a practical and effective alternative to traditional exercise recommendations for sedentary individuals with diabetes or prediabetes. The results of this study may help develop more feasible lifestyle intervention strategies to improve long-term exercise adherence and overall health in individuals with chronic diseases.
详细描述
Physical inactivity and prolonged sedentary behavior are recognized as major risk factors for cardiovascular disease, type 2 diabetes, obesity, and metabolic syndrome. Although current physical activity guidelines recommend at least 150 minutes of moderate-intensity exercise per week, many individuals with chronic conditions such as diabetes or prediabetes are unable to meet these recommendations due to time constraints, low exercise tolerance, comorbidities, or lack of access to exercise facilities. Therefore, alternative exercise strategies that are feasible, flexible, and sustainable are needed for sedentary populations with chronic diseases.
Exercise Snacks is an emerging exercise concept that involves performing short bouts of physical activity multiple times throughout the day rather than completing a single continuous exercise session. These short sessions typically last from 1 to 5 minutes and may include resistance exercises, stair climbing, brisk walking, or other moderate-to-high intensity activities. Previous studies suggest that accumulating short bouts of exercise throughout the day may improve glycemic control, cardiovascular fitness, muscle strength, and exercise adherence. However, the feasibility and acceptability of Exercise Snacks in sedentary individuals with diabetes or prediabetes remain insufficiently studied in clinical settings.
The primary aim of this study is to evaluate the feasibility and acceptability of an Exercise Snacks intervention among sedentary adults with diabetes or prediabetes. Secondary aims include evaluating the preliminary effects of the Exercise Snacks intervention on cardiovascular and metabolic health indicators, physical function, and body composition.
This study will recruit sedentary adults aged 18 to 65 years who have been diagnosed with diabetes or prediabetes. Participants will be randomly assigned to either the Exercise Snacks intervention group or the control group. The intervention period will last 12 weeks.
Participants in the Exercise Snacks group will perform short exercise sessions multiple times per day. Each exercise session will last approximately 3 to 5 minutes and will include simple resistance exercises (such as squats, split squats, resistance band exercises, and curl-ups) and short aerobic activities (such as brisk walking, stair climbing, running in place, or jumping jacks). Participants will be encouraged to perform at least 3 to 4 exercise sessions per day and integrate these activities into their daily routines. Exercise intensity and exercise type will be adjusted based on individual physical capacity and safety considerations.

研究组 & 干预措施
Control Group
Participants assigned to the control group will maintain their usual lifestyle and physical activity habits during the 12-week study period and will not receive the Exercise Snacks intervention. Outcome assessments will be conducted at baseline and at the end of the study period.
Exercise Snacks Group
Participants assigned to the Exercise Snacks group will perform short bouts of exercise multiple times throughout the day for 12 weeks. Each exercise session will last approximately 3-5 minutes and will include simple resistance exercises (such as squats, split squats, resistance band exercises, and curl-ups) and short aerobic activities (such as brisk walking, stair climbing, running in place, or jumping jacks). Participants will be encouraged to perform at least 3-4 exercise sessions per day and integrate these activities into their daily routine. Exercise intensity and duration will be adjusted according to individual physical capacity. Wearable devices or mobile applications may be used to provide reminders and record exercise adherence.
