Implication

Meta-analysis reveals short-bout accumulated exercise reduces postprandial glucose and insulin in adults, indicating frequent activity breaks improve post-meal metabolic regulation.

Key Points

To systematically evaluate the acute effects of interrupting prolonged sedentary behaviour with short-bout accumulated exercise on postprandial glucose, insulin, and triglyceride levels in adults.
Systematic search across seven databases through December 10, 2025, identifying randomised crossover trials comparing short-bout accumulated exercise (≤10 min/bout, inter-bout interval ≥30 min or adequate recovery) with continuous sedentary behaviour.
Included 31 publications representing 29 independent cohorts with 573 unique participants (mean age 47.8 ± 20.3 years, 47.5% female, mean BMI 29.0 ± 5.1 kg/m²), pooling standardised mean differences with random-effects models.
Short-bout exercise significantly reduced postprandial glucose AUC (SMD = -0.53, 95% CI: -0.71 to -0.34, P < 0.001) and insulin AUC (SMD = -0.58, 95% CI: -0.85 to -0.31, P < 0.001) compared with continuous sitting.
Postprandial triglyceride AUC did not significantly differ between short-bout exercise and continuous sitting (SMD = -0.17, 95% CI: -0.48 to 0.15, P = 0.306).
Exploratory subgroup analyses showed significant reductions in glucose and insulin for walking interventions and inter-bout intervals <60 minutes, whereas standing alone or intervals ≥60 minutes showed no statistically significant effect.
