Exercise Snacking and Cardiometabolic Health

2026年7月21日 更新者：Gregory Ruegsegger、University of Wisconsin, River Falls

Influence of Exercise Snacking on Cardiometabolic Health, Physical Activity, and Psychological Well-Being

Regular physical activity is associated with numerous health benefits, yet many young adults do not achieve recommended levels of physical activity. Exercise snacking, which involves performing brief bouts of physical activity throughout the day, may provide a practical alternative to traditional exercise programs by making physical activity easier to incorporate into daily routines.

This randomized controlled trial will evaluate whether a 12-week exercise snacking intervention improves physical activity levels, aerobic fitness, cardiometabolic health, and psychological well-being in insufficiently active young adults. Participants will be randomly assigned to either an exercise snacking intervention or a usual behavior control group. Assessments will be completed at baseline, after the 12-week intervention, and after an additional 12-week follow-up period to determine whether any changes are maintained after the intervention ends.

The study will measure physical activity using wearable activity monitors and assess aerobic fitness, body composition, blood pressure, blood lipids, glucose, exercise motivation, affective responses to exercise, and mental well-being. The findings will help determine whether exercise snacking is an effective and sustainable strategy for improving health in young adults and may inform future physical activity recommendations and interventions

詳細な説明

Regular physical activity reduces the risk of cardiovascular disease, type 2 diabetes, obesity, and other chronic health conditions. Despite these well-established benefits, many young adults do not achieve recommended levels of physical activity. Commonly reported barriers include limited time, competing academic or work demands, and difficulty maintaining structured exercise programs.

Exercise snacking, defined as accumulating multiple brief bouts of moderate-to-vigorous physical activity throughout the day, has emerged as a potential strategy for increasing physical activity while minimizing many of the barriers associated with traditional exercise programs. Although short bouts of physical activity have demonstrated favorable acute physiological effects, relatively few randomized controlled trials have evaluated whether exercise snacking produces sustained improvements in objectively measured physical activity, physical fitness, cardiometabolic health, and psychological outcomes in free-living young adults.

The purpose of this study is to determine whether a 12-week exercise snacking intervention improves physical activity behavior, aerobic fitness, cardiometabolic health, exercise motivation, affective responses to physical activity, and psychological well-being compared with a usual behavior control group. Participants will be randomly assigned to either an exercise snacking intervention or a control condition. Following completion of the intervention, participants will be observed for an additional 12 weeks to evaluate the maintenance of behavioral and physiological changes after structured support is withdrawn.

The primary objectives are to determine whether exercise snacking increases objectively measured physical activity and improves aerobic fitness. Secondary objectives are to evaluate changes in body composition, blood pressure, fasting cardiometabolic biomarkers, exercise motivation, affective responses to exercise, and psychological well-being. Exploratory analyses will examine whether changes in motivation and affective responses are associated with long-term maintenance of physical activity during the follow-up period.

This study will contribute to the growing evidence regarding practical, scalable approaches for increasing physical activity among young adults and may help inform future lifestyle interventions and public health recommendations aimed at promoting long-term engagement in regular physical activity

介入・治療
実験的：Exercise Snacking
Participants assigned to the exercise snacking group will complete a 12-week intervention consisting of multiple brief bouts (approximately 1-3 minutes each) of moderate-to-vigorous physical activity performed throughout the day. Participants will receive written instructions, examples of appropriate exercise snacks, and periodic check-ins to support adherence. The intervention is designed to increase daily physical activity by integrating short bouts of exercise into normal daily routines.
行動：Exercise Snacking
Participants assigned to the intervention group will complete multiple brief bouts of moderate-to-vigorous physical activity throughout each day for 12 weeks. Each exercise snack will typically last approximately 1-3 minutes and may include activities such as stair climbing, brisk walking, repeated sit-to-stands, body-weight squats, or other moderate-to-vigorous activities that can be incorporated into daily routines. Participants will receive standardized written instructions, examples of exercise snacks, and periodic follow-up visits to monitor adherence and reinforce study procedures.
介入なし：Usual Behavior Control
Participants assigned to the control group will continue their usual daily activities for 12 weeks and will not receive instruction regarding exercise snacking or any structured physical activity program during the intervention period. They will complete the same outcome assessments as participants in the intervention group.

Exercise motivation will be assessed using the 24-item Behavioral Regulation in Exercise Questionnaire-3 (BREQ-3). The questionnaire produces six subscale scores: amotivation, external regulation, introjected regulation, identified regulation, integrated regulation, and intrinsic regulation. Each subscale is calculated as the mean of four items and ranges from 0 to 4. Higher scores indicate a greater degree of the corresponding type of exercise motivation; therefore, higher scores do not uniformly represent a better or worse outcome.
Baseline, Week 12, Week 24
Psychological Well-Being
時間枠：Baseline, Week 12, Week 24
Psychological well-being will be assessed using the World Health Organization-Five Well-Being Index (WHO-5). The five items are summed to produce a raw total score ranging from 0 to 25. Higher scores indicate better psychological well-being.
Baseline, Week 12, Week 24
Depressive Symptoms
時間枠：Baseline, Week 12, Week 24
Depressive symptoms will be assessed using the 9-item Patient Health Questionnaire (PHQ-9). Items are summed to produce a total score ranging from 0 to 27. Higher scores indicate more severe depressive symptoms and therefore a worse outcome.
Baseline, Week 12, Week 24
Anxiety Symptoms
時間枠：Baseline, Week 12, Week 24
Anxiety symptoms will be assessed using the 7-item Generalized Anxiety Disorder scale (GAD-7). Items are summed to produce a total score ranging from 0 to 21. Higher scores indicate more severe anxiety symptoms and therefore a worse outcome.
Baseline, Week 12, Week 24
Perceived Stress
時間枠：Baseline, Week 12, Week 24
Perceived stress will be assessed using the 10-item Perceived Stress Scale (PSS-10). Items are summed after reverse-scoring the positively stated items, producing a total score ranging from 0 to 40. Higher scores indicate greater perceived stress and therefore a worse outcome.
Baseline, Week 12, Week 24
