Glycogen concentrations in the sedentary group were as follows: soleus, 5. Glycogen concentrations in the post-exercise group were as follows: soleus, 1. These results indicated that endurance exercise in this study reduced muscle and liver glycogen concentrations.
There were no significant differences in liver glycogen concentrations between the two groups Fig. A Soleus muscle glycogen concentration; B Plantaris muscle glycogen concentration; C Liver glycogen concentration.
Given that glucose is absorbed in the small intestine and transported to the liver through the portal vein, we next evaluated portal plasma glucose concentrations. To clarify the mechanism of different administration methods on glycogen recovery, signaling pathways in the plantaris muscle were examined.

In this study, we examined glycogen synthesis and also measured the utilization of exogenous glucose.
The Δ 13 CO 2 iAUC was similar between the two groups Fig. A Amount Dextrosr change in 13 CO 2 ; B Δ 13 CO 2 iAUC. To the best of our knowledge, this is the first study to determine the effect of differences in the frequency of carbohydrate intake on glycogen recovery in the early phase post-exercise.
Our results showed that bolus high dose and single administration immediately after the exercise glucose intake enhanced post-exercise muscle glycogen repletion in the plantaris muscle as compared to pulsed low dose and frequent administration during the post-exercise phase glucose intake.
In contrast, liver glycogen repletion was enhanced by pulsed glucose intake compared with that after bolus glucose intake. Glycogen is mainly stored in the liver and skeletal muscles. Glucose transport into skeletal muscles is mediated by the GLUT1 and GLUT4 proteins [ 15 ]. GLUT1 is found in the plasma membrane and contributes to basal glucose transport [ 16 ], while the more abundant GLUT4 is largely sequestered intracellularly from where it is rapidly translocated to the cell surface in response to insulin and exercise [ 16 ].
Insulin-stimulated glucose uptake into the muscles is enhanced by exercise [ 17 ]. Increased insulin secretion enhances skeletal muscle glycogen recovery after exercise [ 18 ]. Hence, it is important to increase insulin secretion after exercise.
In this investigation, plasma insulin concentration in the bolus group was significantly higher than that in the pulse group Fig.
Our results suggest that a high amount of glucose ingestion is required at once to increase insulin secretion and promote glucose uptake. Furthermore, Akt phosphorylation was higher in the B group than in the B group. However, there was no difference among the B, P, and P groups in this study Fig.
Akt pathway plays an important role in glucose uptake into the muscles [ 19 ]. Therefore, it is possible that activation of Akt phosphorylation by increased insulin secretion may be partly responsible for higher muscle glycogen recovery in the bolus group than in the pulse group.
A previous study reported that activating gluconeogenesis and inactivating glycolysis enhanced glycogen repletion in the skeletal muscle and liver [ 20 ]. Furthermore, we previously reported that enhancement of energy expenditure during the post-exercise period suppressed glycogen recovery [ 21 ].
Therefore, it is necessary to consider glycogen recovery in terms of not only glucose uptake and glycogen synthesis but also glucose consumption. In this experiment, 13 C glucose was used to assess the utilization of exogenous glucose, but no difference was found between the two groups i.
Thus, differences in mode of glucose administration may not affect the utilization of exogenous glucose during the glycogen recovery period. Furthermore, increased meal frequency might slow small-intestinal absorption of glucose [ 22 ].

Disclosure: PricePlow relies on pricing from stores with which we have a business relationship. We work hard to keep pricing current, but you may find a better offer. With low-carb diets all the rage, and the mainstream nutrition scene increasingly concerned with avoiding blood sugar spikes, why would we want to consume something like dextrose? The answer boils down to glycogen — the rapidly accessible form of glucose that our bodies store in muscle and liver tissue. Whenever we experience something that increases our glucose consumption, whether it be a mental or a physical stressor, our bodies mobilize glycogen and release it into our bloodstream as glucose in order to stabilize blood glucose level. Even on a ketogenic diet , designed to minimize the consumption of dietary carbohydrates, our bodies still need some glucose — even after full fat-adaptation — and are constantly making new glycogen through a process called gluconeogenesis , [3] using mostly dietary protein as a substrate. Whether the body can fully replenish its glycogen stores is a subject of intense debate, especially among athletes. In other words, as with almost everything else in the nutrition and fitness world, one size does not fit all. The reality is that while the high-fat ketogenic way of eating might be great for some people, others may find through trial and error that they do better by replenishing glycogen with dietary carbohydrates instead of relying on gluconeogenesis. If you are in the latter camp, then dextrose is a carbohydrate with some uniquely beneficial properties that you should think about trying. However, not all carbohydrates are necessarily created equal. For example, in one study, nine cyclists completed three different 64 kilometer time trials TT where each rider was randomized to one of three groups: the first group consumed honey during the TT, the second group consumed dextrose, and the third group got a non-caloric placebo. The interesting thing is that the dextrose group slightly outperformed the honey group , by about 12 seconds minutes and 30 seconds vs. Riders ingesting dextrose had a higher power output than those ingesting honey. These differences may seem slight, but a watt increase in average power is the kind of return that an experienced cyclist might expect from a whole season of structured training. In another study, researchers put dextrose up against ribose , a sugar produced endogenously by the human body from food. The researchers randomized 31 female collegiate rowers to get 10 grams of either ribose or dextrose before and after exercise for eight weeks, and measured their performance in 2, meter time trials. The result was that the dextrose group outperformed the ribose group , [9] with the dextrose group getting about 15 seconds faster in the time trial, whereas the ribose group only got 5 seconds faster. These are intriguing studies, but dextrose is a neglected subject in sports nutrition research. However, there is one very good theoretical reason for suspecting that dextrose might be a better choice than, say, honey or sucrose table sugar : and that is the total absence of fructose in the dextrose molecule. The chemical structure of sucrose : one part glucose and one part fructose [10]. CAPTION: The chemical structure of sucrose : one part glucose and one part fructose [10]. Dextrose, on the other hand, is pure D-glucose. Instead, your liver turns it into mostly liver glycogen — as opposed to muscle glycogen — which is used by the body for different purposes than athletic performance. Added to.

Dextrose Muscle Glycogen -
This will put a stop on breaking down any more muscle, and switch your body into repair, rebuild and recovery mode. Our first choice is dextrose. Taking in dextrose immediately following your workout can help maximize your gains and drive nutrient uptake. Every time you train, your body uses stored glycogen as fuel.
Glycogen is made of long chains of glucose molecules that gets broken down to fuel everything from your brain to muscles to organs.
In muscles where much of it is stored, glycogen functions as an immediate reserve source of glucose for muscle cells. Following intense workouts, we drain much of our reserves. However, the refueling is necessary after your tank is drained.
The fastest way to refuel your glycogen after workouts is to use a simple sugar such as dextrose. Dextrose is a readily absorbed isomer, also known as D-glucose. Dextrose has another great impact on sports nutrition.
In order to repair and refuel, lots of nutrients must be moved around the body. Insulin is famous for its many roles in the human body. As a hormone, Insulin serves in the transportation system of nutrients.
In a sense, it helps nutrients from the bloodstream to the muscles to start the recovery and rebuilding process. The nutrients in the bloodstream are going to build up your muscle tissue and the insulin is the involved in the transportation from the bloodstream to improve your performance!
Because dextrose is a fast-digesting simple sugar, it helps to raise blood sugar glucose levels quickly, causing a fast spike in nutrient-transporting insulin into the bloodstream.
If the spike is from unhealthy eating, you will drive nutrients into fat cells as well. Remember, dextrose speeds up nutrient absorption, whereas a slower digesting carbohydrate would not help shuttle nutrients as fast.
