"Glycogen resynthesis" refers to the process of replenishing or restoring the stored form of sugar called glycogen in our muscles. After intense exercise or physical activity, glycogen levels decrease, and this process helps the body regain those energy stores.
Full definition
The study, «High rates of
muscle glycogen resynthesis after exhaustive exercise when carbohydrate is co-ingested with caffeine,» is by David J. Pedersen, Sarah J. Lessard, Vernon G. Coffey, Emmanuel G. Churchley, Andrew M. Wootton, They Ng, Matthew J. Watt and John A. Hawley.
[2] Furthermore, because of Waxy Maize's ability to
increase glycogen resynthesis post workout, it is found that consuming a HMW carb improves performance for subsequent exercises.
What's more noteworthy is that HMW carbohydrates leads to increased
glycogen resynthesis post workout - as mentioned in the study above.
Those who train a muscle group to glycogen depletion, and then must compete with those same glycogen - depleted muscles within the same day (or more specifically, within ~ 8 hrs or less) can indeed benefit from consuming high - GI carbs in order to
expedite glycogen resynthesis for maximizing endurance performance in the subsequent bout.
Muscle
glycogen resynthesis rate in humans after supplementation of drinks containing carbohydrates with low and high molecular masses.
While there is still some overlap between running and swimming,
maximizing glycogen resynthesis will still be less important since you're using different muscle groups.
Since your glycogen has to be restored after a training session it is important to consume carbohydrates with a high - glycemic index to
boost glycogen resynthesis.
As muscle damaging exercise has previously been reported to decrease GLUT4 translocation and subsequent rates of muscle glycogen resynthesis [49], the possibility that it also may impart a negative effect on protein transporters and rates of protein synthesis can not be discounted.
They measured recovery in two ways: power output (how hard their muscles could work) and
muscle glycogen resynthesis (how fast their muscles refilled their carbohydrate supply).
Glycogen resynthesis after exercise: effect of carbohydrate intake.
If you eat before or during a workout, you'll also use less muscle glycogen during exercise.51 - 53 The food you ate before and / or during your workout will still be digesting after you finish training, supplying carbs for
glycogen resynthesis.
