High-intensity exercise (sprints/burst training/circuits) can work to improve insulin sensitivity, which can help with glucose control and inevitably allow you to utilize carbohydrates better.
How? During a HIIT sessions, blood glucose from glycogen breakdown is elevated for fuel (HIIT uses a different energy system compared to LISS – aerobic/anaerobic), which will result in a decline in blood glucose during the HIIT session.
Since you are basically going at your max, you will also be having a lot more muscle contractions compared to low intensity exercise, which will stimulate the glucose shuttle transporters (GLUT4 translocaters) to take up glucose into the working muscle.
If you are looking for a training guide that will yield a more positive hormonal profile – I highly recommend checking out “The Happy Hormone 12-Week Exercise Guide” available for $10 in the guide section of my website
