Understanding Muscle Fatigue
Ever wondered why it is we get tired, sometimes to the point where we can no longer even move our limbs. Muscle fatigue is a topic of intense research and study as biochemists and biophysicists seek to explain what exactly occurs in our bodies that leads to such exhaustion. The 100 year old theory that fatigue is due solely to lactic acid buildup in the muscle cells has recently been contested as two newly discovered factors now are seen as playing roles in muscle exhaustion.Let me start off by saying that this is going to be a technical article, not terribly so, but more than you might be used to. Do not be afraid though, by understanding what is going on in our bodies we can then train in more efficient ways.
The lactate model of muscle fatigue can be summed up by saying that after partial depletion of our bodies glycogen stores, glycogen phosphorylase (the fight-or-flight enzyme) steps in to convert the now depleted glycogen stores into glucose, the basic energy unit for all cellular functions. This process is called glycogenolysis; after this occurs the resulting glucose is then converted to ATP or adenosine triphosphate, the basic energy unit for all metabolic processes. This is as far in detail as we need to go but what is important to know is that this production of ATP via the degradation of glycogen is very inefficient and the faster rate of the oxidation of glucose versus absorption of lactate results in excess lactate production.
to get a swim suit body or get that mythic six pack so I can show the world. It starts with knowing how to plan a lean diet. Rule number one: never skip meals. Dropping the number of meals you take in per day lowers your metabolic rate and increases the level of nutrient oxidation. This means you will feel lethargic and what fat you have, your body will fight to keep as long as possible based on a primal survival instinct. Rule number two: eat 5 to 6 meals per day. This will kick start your metabolism leading to a higher basal metabolic rate, or BMR, and will stabilize your level of nutrient oxidation making your body more efficient at utilizing food you put in it.
convinced by the marketing madness thrown at them by the major supplement companies out there. Well to those people whose breakfast looks like a bunch of pills and various powders, I want to hear this: have you seen any measurable progress towards your goal that you can attribute to this pseudo pharmacy you take in every day? If you can say yes to that question, please email me or leave a comment, I want to hear from you. Now to the majority that will have answered that question with a no lets start talking real sense.
