Why the study?
Does endurance exercise training result in a long-term adaptive increase in sensitivity of skeletal muscle to insulin in rats?
Population
Rats (sedentary and endurance exercise-trained via treadmill-running)
Comparison
Endurance exercise training and acute exercise vs Sedentary rats
Design
Preclinical
Follow-up
Up to 40-46 hours after last exercise session

Residual effects of recent exercise explain transient glucose uptake gains in rats; leaves open whether chronic insulin sensitivity adaptations exist and should not yet change practice.
Does endurance exercise training result in a long-term adaptive increase in sensitivity of skeletal muscle to insulin in rats?
Differences in muscle glucose uptake between trained and untrained rats are due to residual effects of the last exercise session rather than a long-term adaptive increase in insulin sensitivity.
