Brief, intermittent bouts of physical activity designed to interrupt prolonged sedentary behavior; specific bout duration, intensity, rest, and session counts were heterogeneous or not stated.
Exercise Snacks
Exercise Snacks: Systematic Review of Health Outcomes
This systematic review examined brief, intermittent exercise snacks in adults, including older people and those with chronic conditions. Across 26 studies, findings suggested improvements in metabolic, cardiovascular, functional, cognitive, and mood-related outcomes, with good feasibility.

Intervention
Main findings
Across the included studies, exercise snacks were reported to improve postprandial glucose, insulin, and triglyceride responses; reduce blood pressure; preserve endothelial and cerebral blood flow; and enhance cardiorespiratory fitness. Older adults showed gains in lower-limb strength and mobility, while emerging findings suggested improvements in mood, fatigue, and cognition. Feasibility studies reported high acceptability and adherence.
What this may mean in practice
Snacksmate's reading of the evidence — not a quotation from the original paper.
This review suggests that brief activity breaks are a feasible approach associated with improvements across several health domains, but varied interventions and reliance on narrative synthesis mean the best protocols and long-term effects remain uncertain.
Limitations
Intervention heterogeneity led the review to prioritize narrative synthesis; the authors also identified a need for research on optimal protocols and long-term sustainability across varied populations.
