The ONLY Sugar That Won't Raise Your Blood Sugar

High GI glycogen replenishment -

A post shared by BarBend Strength Sports News barbend. The other reason for choosing high GI carbs is the rate at which they can replenish energy stores.

Your muscles store carbohydrates to use for energy during training in a form called glycogen. During training, our muscles use up their stores of glycogen and it is common practice to eat high glycemic carbohydrates to rapidly recover these glycogen stores for your next training session.

Early nutrient timing research found that a mixture of carbohydrates and protein post-workout leads to the fastest rate of glycogen replenishment in the hours immediately following a training session.

In general, higher GI carbohydrates will replenish glycogen faster than lower GI carbs. However, there is plenty of evidence that shows mid GI carbs are just as effective at replenishing glycogen stores.

Kreider and his team looked at the effect of protein combined with one of three different carb sources, with three different glycemic index ratings on insulin concentrations, blood glucose levels, anabolic hormones and marks of immune system suppression.

The study actually showed that the lowest-glycemic liquid carb supplement honey powder plus protein had the greatest effect raising blood glucose levels post-exercise, and that all three liquid carbs raised insulin concentrations to the same degree.

This is a relevant study because it was performed using resistance trained athletes, where others used cyclists, soccer players, or other endurance athletes.

The Kreider study shows us that the combination of carbohydrate and protein post-workout, and the dose of the combination, are more important than the glycemic index of the carbohydrate supplement involved. Other research seems to suggest that by the hour mark, total carbohydrate ingested, and not glycemic index , is the most important determinant of muscle glycogen replenishment.

If you are an athlete training hard once per day, it is unlikely that an expensive, super fast acting high GI carb like Waxy Maize Starch or Branched Cyclic Dextrin is necessary for you to optimize performance and recovery.

You can either consume solid food before and after training, or make a shake with a quality protein and carb powder. They are fast acting and generally inexpensive.

As for dose, Alan Aragon recommends resistance training athletes consume roughly 0. The high-glycemic index foods, or fast-burning fuels, like sugars, increase your blood sugar quickly.

This low blood sugar, and the adrenaline and cortisol that it stimulates, can make you feel terrible, and cause a number of different health problems over time.

A diet heavy in high glycemic index foods is not a healthy diet. So if slow-burning, low-glycemic index foods like fruits and vegetables are healthy, and fast-burning, high-glycemic index foods like sugars are unhealthy, why does Tailwind Rebuild, or for that matter Tailwind Endurance Fuel, contain simple sugars?

The answer is exercise. Tailwind Endurance Fuel is taken continuously during long periods of exercise. When used in this way, it never spikes your blood sugar, and keeps you fueled all day long. As an added bonus, the fast-burning sugars in Tailwind can bring you back from bonking if needed, something that a low-glycemic index carbohydrate will not do very well.

A recovery drink needs to solve two problems. It needs a good amount of fast-burning fuel to replenish depleted glycogen. But it also needs some amount of slow-burning carbohydrates to avoid taking your blood sugar on a roller-coaster ride. From the standpoint of glycogen replenishment, you do not need fat in your recovery drink, only carbohydrate and protein.

No matter how fit or lean you are, and no matter how long your endurance event is, you will not deplete your fat reserves during your workout or competition.

When you finish a hard event or training, your glycogen supplies are exhausted, and your muscles need repair and rebuilding.

Exercise simultaneously increases insulin sensitivity so more energy can enter cellsand decreases insulin secretion so more glucose will be available as fuel. The magic hour exists because while insulin suppression ceases after exercise stops, the increased insulin sensitivity persists for about an hour. This is the best time to replenish your glycogen energy stores, and is when you want to refuel after exercise.
