Thread: CARBOHYDRATE LOADING

  1. #31
    Stephen M. Roth, a professor in the department of kinesiology at the University of Maryland, explains.

    As our bodies perform strenuous exercise, we begin to breathe faster as we attempt to shuttle more oxygen to our working muscles. The body prefers to generate most of its energy using aerobic methods, meaning with oxygen. Some circumstances, however, --such as evading the historical saber tooth tiger or lifting heavy weights--require energy production faster than our bodies can adequately deliver oxygen. In those cases, the working muscles generate energy anaerobically. This energy comes from glucose through a process called glycolysis, in which glucose is broken down or metabolized into a substance called pyruvate through a series of steps. When the body has plenty of oxygen, pyruvate is shuttled to an aerobic pathway to be further broken down for more energy. But when oxygen is limited, the body temporarily converts pyruvate into a substance called lactate, which allows glucose breakdown--and thus energy production--to continue. The working muscle cells can continue this type of anaerobic energy production at high rates for one to three minutes, during which time lactate can accumulate to high levels.

    A side effect of high lactate levels is an increase in the acidity of the muscle cells, along with disruptions of other metabolites. The same metabolic pathways that permit the breakdown of glucose to energy perform poorly in this acidic environment. On the surface, it seems counterproductive that a working muscle would produce something that would slow its capacity for more work. In reality, this is a natural defense mechanism for the body; it prevents permanent damage during extreme exertion by slowing the key systems needed to maintain muscle contraction. Once the body slows down, oxygen becomes available and lactate reverts back to pyruvate, allowing continued aerobic metabolism and energy for the body¿s recovery from the strenuous event.

    Contrary to popular opinion, lactate or, as it is often called, lactic acid buildup is not responsible for the muscle soreness felt in the days following strenuous exercise. Rather, the production of lactate and other metabolites during extreme exertion results in the burning sensation often felt in active muscles, though which exact metabolites are involved remains unclear. This often painful sensation also gets us to stop overworking the body, thus forcing a recovery period in which the body clears the lactate and other metabolites.

    Researchers who have examined lactate levels right after exercise found little correlation with the level of muscle soreness felt a few days later. This delayed-onset muscle soreness, or DOMS as it is called by exercise physiologists, is characterized by sometimes severe muscle tenderness as well as loss of strength and range of motion, usually reaching a peak 24 to 72 hours after the extreme exercise event.

    Though the precise cause of DOMS is still unknown, most research points to actual muscle cell damage and an elevated release of various metabolites into the tissue surrounding the muscle cells. These responses to extreme exercise result in an inflammatory-repair response, leading to swelling and soreness that peaks a day or two after the event and resolves a few days later, depending on the severity of the damage. In fact, the type of muscle contraction appears to be a key factor in the development of DOMS. When a muscle lengthens against a load--imagine your flexed arms attempting to catch a thousand pound weight--the muscle contraction is said to be eccentric. In other words, the muscle is actively contracting, attempting to shorten its length, but it is failing. These eccentric contractions have been shown to result in more muscle cell damage than is seen with typical concentric contractions, in which a muscle successfully shortens during contraction against a load. Thus, exercises that involve many eccentric contractions, such as downhill running, will result in the most severe DOMS, even without any noticeable burning sensations in the muscles during the event.
    Found dis article... Dont know if its sceintifly backed up....and if its applicable to dogs

    The last dog I worked got 15% carbs in his diet. I'm gonna try to knock that down closer to 10-12% the next time. I posted an article on this site under the the Conditioning Articles, Rendering Sense into Fat, that will explain a lot of what ya'll are wanting to know.

    Carbo loading WILL give your dog a 10/15 min turbo boost at the start, wich wil give him a extra15 min of energy overal..

    How about the negative effects Jack has highlighted in the article.

    wel there are always 2 sides to a story and ore flip side to every coin!. same as raw feeding and kibble. They both have merrit.and both have flaws and good points. my info and ecsperienced is not only backt up bij myself but from famouse dogman from the past from colby/ armitage/ mayfield ecetera ecetera. but iven more imoprtend from the greyhound world, where the sprinters get more carbs and the stayers more fat, yet in those diets the gross is stil carbs.. when you are dealing with Eli/alligator ore pure bully ore those typ of dogs they do have a ecsposif driving start where they use up massif amounds of fuel. where the bolio tombstone/ redboy typ of dogs ""dont"", they are usualy dogs that take the botoom and ore are very good clever dogs that ride the head in retreat.

    those type of dogs cary better on a more fat/protien typ diet.then the other who need that torque..
    most dogman preach gospel on there own ecsperienses and ore so called sientific studies who lack real live testing and ore are based on humans ore sledge dogs.ore wolfs wich is compleatly irelevand when it comes to our breed..
    a dog in contray to man only swet out of there mouths and feet .
    the APBT is a sub spiecies evolved into a compleatly diferend animal, where it looks like a dog , shits like a dog ""eats"" like a dog pissis like a dog , but it has nothing more to do with what the world considers a dog..
    This true human slection ""against"" the rulles of nature!!.
    never sientificly reasearchst due to the iligal caracter where the breed has lived and bred in..

    At the same time Sledge dogs who are often refeurd to as a comparison in food discussions consirning diets., work in ecstreem cold iviromends lots of fresh and DENSH air carying ""lots"" of oxygen, wich is needed to ""burn"" the fat fuel witch is the ""slowest"" energy fuel dilivery there is for man AND dog ore any mamal for that matter, (look at artic animals they NEED fat insted of carbs as a energy and isolation sours)

    where as carbs used 1/3 less oxygen to be used as a quik fuel dilivery. you can compear it with gasoline and diesel fuel, and our dogs are hybrids in that matter... at the same time the sledge dog works with his mouth ""open"" Being able to consume ""vasts"" amounds of cold fresh ""densh"" air to be ""able"" to burn of the fat. and cope with the heat that comes along with that. insted of a APBT who works with his mouth ""closed"" in ""hotter"" inviremends with mutch ""less"" oxygen intake is availeble to use ..

    where fat wil be a mutch slower energy sours... just like a bad tunned cumbustion engine who cant properly burn its fuel due to bad air fuel ratio!..
    So those type of comparisens and teoryes is like comparing apples with oranges....
    now you might say wel what if the carbs are burned of afther 15 min. then the dog needs to go to the fat fuel and the lactic asidproduced tru fast burned carbs wil make him runn hot ..absolutly ""true"", But that same dog is on his fat resirves 15 min later!!!!!!!. And wil run just as hot afther 20/25 min as the fat diet dog who due to the lesser oxygen air fuel ration intake, is running just as hot!!!!!!!!!!Being forced to tug along with the energy onslought of a carb fueld dog that defenatly has a faster pace........ so teoreticly the carb loaded dog has more fuel reserves for the long run ... NOW if he faces a mutch better uponend then al of this gose out the window!!. never the less. conditioners try to get the dog in max shape ore chanse to compeat.. and at times where it comes douwn to the nitty gritty. i lean to the carb loaded dog... this being said AGAIN it thepends on what typ of dogs from what type of bloodlines ore famelies your dealing with..

    I know these dogs quite well. They are 40 minute killers. If they can't stop you in that amount of time ,you are going to win. Hense the carb load diet.

    I also noticed that about Fat Bill's keep. When I had my dogs on it, they had energy for about 40-45 minutes. After that they were done and just holding on to the other dog.

    The reason sled dogs are used in research surrounding fat/carbs is due to the endurance aspect. It has nothing to do with how cold it is. It's related to the conditioning of the dog for the event. The entire issue about carbs/fats is that the dog should be changed at least 4-6 weeks to a higher fat diet so the dog's body grows accustomed to the higher fat content. Lower carbs/higher fat improves the conditioning of the dog. The conditioning allows the dog to do what? Go at a faster pace, for longer, if properly conditioned. Carb loading is great for people. Carb loading simply isn't optimal for dogs as it simply isn't their primary energy source, and that will never change.

    ignorense is bliss i gues, as carb loading has EVERYTING to do with it........... read ""with our"" dogs when it comes to heat, cold dense air, ecetera in order to adjust diet /conditioning. Are you aware or where you around where upto the mid 70,s of the last century.. Shows where agreed upon minimum and maximum hights above sea level as wel !!. To compensate for bad non dense air, ore the oposit. To get as mutch advantige for there dogs!!??... Why do you think the greatest atleats train high up in the mountains!! ..

    cold and heat and densh air has EVERYTING to do with burning diferend fuels and getting the max out of the fuel used.. hell if you runn your sledge dogs team ABOVE a sirtin temparature you get aressted in some of parts of the world!! because they heat up so quik... why do you think these type of dogs can sleep perfectly wel in minus 30 in snow storms .. it isend just there nice fury coats my frind..Its there genetic make up and those are compleatly diferend then our dogs.

    And its very Obviusly that you dont fuel up a diesel engine with gasoline !.
    and sins when thuse the APBT do its thing on a steady pace when sporting????????, where cruising speed is esentional in order to ditermen how far and long they CAN runn!!!!!.......
    you think a texas condition fat/protien diet dog at sea level can compeat when he gets up in the mountains with the same heat?? and less oxygen levels in the air!!. that dog wil fall flat on its face within 25 min to never rize on its feet again... now feed that dog carbs with his fat and protien diet. and you see a diferend picture as carbs need 1/3 less oxygen to burn and diliver enery... last but not least did anybody ore you ever tought about WHERE those sientific studies on those sledge dogs and there diets where held!!??. i can tell you one thing it wassend in Texas ore new mexico ore in loisiana!!.................
