Exercise Snacks and Physical Function: Meta-Analysis
This systematic review and meta-analysis of 11 randomized trials examined exercise snacks in 472 healthy or sub-healthy adults. Brief, frequent activity bouts improved several fitness and physical-function measures, but not fatigue or BMI.

Intervention
Main findings
Across 11 randomized controlled trials, exercise snacks increased absolute peak power output, maximal oxygen uptake, and 60-second sit-to-stand repetitions, while reducing body fat percentage. Differences in fatigue and BMI were not statistically significant.
What this may mean in practice
Snacksmate's reading of the evidence — not a quotation from the original paper.
Across the included randomized trials, exercise snacks improved several measures of fitness and physical function and reduced body fat percentage, while the evidence did not establish a clear effect on fatigue or BMI.
