Lower GI foods can also result in
higher muscle glycogen levels (storing more carbs in the muscle), and less chance of storing the extra glucose as fat.
3) In fact, it's usually better to have some guarantee that you have
high muscle glycogen for your higher intensity training, so typically it's better that you do your (short) strength workouts when you're not carb depleted.

It seems reasonable to suggest that rather than simply maintaining a
high work rate until the RPE does rise to reach near - maximal levels, the exercising athlete would instead reduce the work rate under conditions of elevated body temperature8 — 10 or depleted

During the post-workout window, certain nutrients such as water,
high glycemic index carbs and amino acids can help you stimulate better recovery by providing your
muscles with the raw materials they need — optimal post-workout nutrition requires plenty of protein to aid in protein synthesis and plenty of carbs to help replenish the depleted
muscle glycogen reserves, as well as create an optimal post-workout metabolic environment.
Besides being a major contributor to the growth and repair of tissues all around the body, vitamin C supports protein metabolism and helps keep testosterone levels
high by reducing cortisol production, while vitamin E plays an important role in preventing

glycogen levels in the
muscle.
By Brad Dieter, PhD and Dylan Dahlquist MS (c) A seminal study performed in the 1990's showed that as we increase exercise intensity blood glucose and
muscle glycogen (aka carbs) are primary fuels used during
higher intensity exercise and fat utilization begins to decline (1).
Carbohydrate - rich foods with a moderate to
high glycemic index provide a readily available source of carbohydrate for
muscle glycogen synthesis, and should be the major carbohydrate choices in recovery meals.
Most
high - quality intra-workouts will contain BCAAs in a 2:1:1 ratio to help fuel skeletal
muscles, preserve
muscle glycogen stores and reduce protein breakdown.
At low intensities, you're burning mostly fat and ketones for fuel so that your body could spare its
muscle glycogen for
higher intensities.
Since the BCAAs provide a direct source of energy for your
muscles during workout, your
glycogen levels remain
high after workout.
One study demonstrated that taking Glutamine during or after a workout, stimulates and increases
glycogen synthesis as effective as taking a
high dose of carbs.The study showed that taking an 8 - gram glutamine solution after an intense workout was as equally effective as taking 60 grams of carbohydrates for restoring
muscle glycogen.The combination of glutamine and carbohydrates (glycose) was even more effective than glutamine or carbohydrates separately.
-- The reason this diet differs from other diets that rely on carbohydrate manipulation, is the fact that the
high / moderate carb days are so important for the
muscles as it helps to flood them full of
glycogen.
Specifically, consuming
high GI foods within the first 30 minutes after training will help you replenish depleted
glycogen levels in the
muscle by elevating your levels of insulin, which is responsible for driving crucial nutrients into your starving
muscles.
Also, in order to replenish the
muscle glycogen that you burned during your workout as fast as possible, your post-workout meal should be a
high - carb one as well.
A few days each week — the night before workout days to build
glycogen stores in your
muscles — try increasing your intake of berries,
higher complex carb veggies (like sweet potatoes), and non-gluten grains.

And similarly, those looking to build
muscle, or those looking to fuel a heavy training load (especially if it's the
high - intensity, glycolytically demanding kind) may want to favour a concentrate product (with some carbohydrate), as this is the prime opportunity to replenish their
glycogen stores.
Fitness specialists recomment that after a workout that depletes
muscle glycogen (so after about one hour of
higher intensity), you eat a meal composed of 3:1 carbohydrate: protein.
Muscle glycogen was modestly, albeit statistically non-significantly lower after ketoadaption; however, ketoadapted athletes relied on a

Our bodies generally draw upon a combination of carbohydrates and fats to produce ATP, with the exception being very short - duration,
high - intensity anaerobic activities, such as a 100 - meter sprint where the primary fuel sources are creatine phosphate, stored ATP, and
muscle glycogen (i.e., carbohydrates stored in the
muscle).
Since
muscle glycogen is what your
muscles use for
high intensity exercise, it's highly unlikely your body will start breaking down protein for glucose when it already has plenty to use from
glycogen.
Post exercise ketone surges will be moderate while post exercise glucose surges will be surprisingly
high, yet transient, and beneficial to the athlete because this transient glucose surge will serve as an endogenous
muscle glycogen storage mechanism.
This also suggests that training with low
muscle glycogen may be counterproductive for athletes who compete in
high intensity events where CHO oxidation plays a significant role in performance, and that this type of training may be more suited to preparation for ultra-endurance activities.
One of the substances that carbs are converted to in the body is
glycogen, which is stored in the
muscles and liver and is the primary source of fuel during intense exercise like weightlifting and
high - intensity interval training.
Particularly during

Working out with weights first helps you burn off most of your stored
muscle glycogen (or carbs) for energy so when you do get ready to do your cardio or interval workout you'll burn a much
higher percentage of fat
It features periods of

If you were a really keen student in
high school, you may remember that insulin takes sugar away from your blood and stores it in your liver and
muscles by converting it to a molecule called «
glycogen».
A cardio workout WO N'T cut it for this... it must be
high intensity resistance training to deplete enough
muscle glycogen to handle restaurant portions of carbohydrates.
Delaying your consumption of carbohydrates post workout will result in reduced
muscle glycogen storage, and because of this, it is standard for most serious athletes to consume a
high carb drink immediately post workout.
They do not hydrate you as quickly as water does but are ideal after doing
high levels of exercise to quickly replace
muscle glycogen stores.
