BCAA

For over fifteen years, I have strongly recommended branch chain amino acids (leucine, isoleucine, and valine) for use while you train. These supplements can increase your lean body mass. I learned this trick a while ago from Drs. Serrano and Di Pasquale. I have used it with athletes who have difficulty increasing their mass.

How does it work? There could be a variety of reasons, namely:

  • Leucine is an important regulator of protein synthesis through reducing protein degradation in humans. Leucine is also very at sparing glucose as a fuel.
  • BCAAs promote protein synthesis in the fat-free body mass.
  • BCAA consumed during training raise both growth hormone and insulin at the same time, hence the increased anti-catabolism and anabolism.
  • The BCAAs, unlike the other amino acids, are used as a form of energy by muscle cells.
  • The study by Carli et al. (1992) showed that supplementing with branched chain amino acids prior to a workout not only prevents a decrease in post-workout testosterone levels, but actually allowed testosterone levels to increase following exercise.
  • BCAAs administration has an anti-catabolic effect by favoring a better testosterone/cortisol ratio.
  • BCAAs administration also reduces the exercise induced increase in the muscle concentration of tyrosine and phenylalanine, therefore indicating a decreased net rate of protein degradation during exercise.
  • There is a serious decrement in post workout soreness when you use BCAA during the training unit.
  • An Italian study on natural bodybuilders showed that 0.2 g of BCAA per kg of bodyweight 30 minutes before workout and 30 minutes after workouts lead to greater increases in lean body mass and strength in the bench press and squat.
  • BCAA decrease body fat (especially visceral fat, the fat that accumulates inside the abdomen and results in that beer gut look.
  • A group of researchers through three different studies demonstrated that BCAA supplementation might also improve exercise-induced declines in some aspects of mental functioning.
  • Prolonging endurance performance in the heat.
  • The prevention of muscle loss at high altitudes
  • One of the causes of fatigue during exercise is the enhanced conversion of the amino acid tryptophan in to 5-HTP, which makes you drowsy, and fatigued. As you may be aware, 5 HTP is sold a supplement to enhance sleep, particularly for the fibromyalgia market.

How much BCAA should you take?

I recommend taking 0.44 g per Kg of bodyweight. Take half of this dosage within 30 minutes before training. Take the other half right after training.

For example, if you weigh 90 kilograms (198 lbs), take 40 grams of branch chain amino acids. If you are on a restricted budget, use at least 20 grams. Otherwise, don't bother. Using this type of dosage, it is not uncommon for some of my clients to gain 9 lbs of lean body mass in just 3 weeks using this protocol.

Some people have recommend taking BCAA during traditional sleeping hours, waking during the night to take some tablets. In this case, the rationale is that a greater anabolic state will be created. That idea is completely worthless. Sleep should not be interrupted no matter what! As soon as you wake up for more than three seconds, you suppress completely the production of melatonin, the restorative, anti-aging hormone.

BCAAs are best used as an « intra-workout » workout supplement.

STRESS

S T R E S S

   

I once heard of a corporate personal trainer, who had established a very lucrative business working with a large law firm.  His days were filled training successful and driven attorneys.  Their company was aware of the importance of physical fitness and of the good health of their employees, indeed more and more corporations realize that if they are to demand a high work ethic in a high pressure environment, then they need to make available health and fitness benefits.

   

. 

Why then, after almost a decade of this work did the trainer give up such a lucrative position?  To quit a secure and financially rewarding position in which, one would think, you would be working with determined individuals, people that are motivated by success and are able to follow a course of action in order to achieve the desired outcome. 

   

Why?  The trainer eventually threw the towel in the ring because he felt his work was futile.  In one aspect he provided a great service, but what was desired by the majority of his clients was physical improvement, body composition changes, that is a reduction in body fat, to create a more metabolically active physique that is leaner and stronger.  The trainer was not getting these results and he knew why, he was up against an  obstacle that he could not control or work around  ......  STRESS.

   

In this case the demanding workload that the attorneys had to address meant a lot of stress.  Stress an accepted part of life and to some extent an advantageous element of life that when sporadic and in moderation can challenge us to do our best.  The adrenaline response of stress can enable extra power to be available to the muscles and it can help us mentally focus on the task in hand.  An example of each would be the pressure to perform at a sporting event and the mental focus needed to recall and concentrate in an important exam.

   

  Once the cause of the stress is removed the chemicals produced by stress (epinephrine, nor epinephrine and cortisol) are washed away in the blood and safely removed from the body, much the same way as lactic acid - a by-product of muscle contraction is safely removed from the muscles after a workout..

   

Stress is not necessarily a problem, our response to stress is immediate, it serves a purpose and the body can easily restore its own natural balance and so continue to pre stress behavior.

   

TOO MUCH OF A GOOD THING

   

The problems start when we overload the system with stress. When it is coming at you many directions then ' Stress becomes Distress,' The  situation is prolonged  and the reactive chemicals continue to be produced, instead of being reabsorbed and discarded they continue tobuild up in the system.  A person in 'Distress' is vulnerable on many levels; the link between stress and a variety of health issues from heart disease to infertility  is already well established and widely discussed. 

   

Back then to the fitness trainer.  The attorney clients obviously have stressful jobs, but the trainer found that in around 80% of his cases not only did his clients not reduce their levels of body fat, but their body composition changed with a negative swing.

   

"Moderation is the key", "it's not the use but the abuse" we have heard these phrases thrown around to describe the consumption of dietary fat or the use of alcohol even exercise routines , it is a general way of thinking that allows "most things in moderation". There are exceptions, however stress is not one of them.

   

CATABOLIC CORTISOL

   

Cortisol, released from the adrenal cortex in response to stress can suppress the immune system and the inflammatory reaction.  This can be good thing as damaged cells release chemicals that cause inflammation.

Also cortisol has the affect of increasing blood sugar levels.  It can do this as it enables the body to convert amino acids (breaking down protein stores) into glucose, a process known as 'gluconeogenesis', it also trys to preserve glucose by attempting the shift of using glucose stores for energy to using fatty acid stores for energy instead.

   

In the short-term cortisol helps us cope with internal and external environmental changes, although not fundamental to life cortisol does play a huge part in managing stress.

   

MORE IS NOT NECESSARILY BETTER

   

Back again then to the attorneys.  In seeking the physical gains they are up against self-sabotage.  With skipped meals and late nights added to the stress of work, this doesn't diminish unless you are able to make a conscience effort.

   

The cortisol keeps doing its job and so the breakdown of protein continues. The stored protein is from muscle tissue and you become "Catabolic" - instead of increasing your lean body you are decreasing it, muscle is being broken down to form glucose, an unusual process except in the situation where the body recognizes stress and the need to increase blood glucose stores.

   

Muscle is also the furnace of fat burning. When fat is broken down it travels in the blood stream to working muscles where it is burnt up for energy.  As you lose muscle you so reduce your ability to burn fat.  This is where many diets for fat loss fail.  The perseverance of muscle tissue is crucial to fat loss.  With very low calorie diets weight (not fat) is initially lost, but your ability to burn fat has been reduced, this explains the all to common rebound or "yo yo  diet." If you return your calories to their previous level (or more) fat storage will increase as during the calorie deprivation stage you lost muscle weight and so reduced your ability to burn fat. 

   

The more cortisol produced as a by-product of stress creates a catabolic environment, you lose muscle, your ability to burn fat is reduced, you find yourself heading in the wrong direction. This causes some to train harder and longer ....  more stress, this time physical stress.

   

Add to this any family problems or health concerns and we begin to see how after many years of the same pattern the fitness trainer considered his efforts futile as so moved on.

   

MITIGATING STRESS

   

The law firm is just an example of a well-told story, the story however runs deeper and stronger throughout our society.  Stress related conditions include heart disease, obesity, cancer, depression, anxiety, substance abuse and numerous immune and infectious disorders.

   

Maybe the first step is recognizing where stress lies, it is not always in the most obvious places.  Consider over-training, under or overeating, smoking, drugs and alcohol, poor nutrition and poor sleep. Then consider grief, finance, and moving, children, school,  work or hostility and arguments as well as the demands and expectations of others.

   

Stress that leads to distress may seem unavoidable but by identifying where it lies you can then work on the areas where you have some control, consider those below

   

1.  Nutrition   eating every 3-4 hours, learn to be prepared and carry snacks with you.  Eating balanced meals avoiding the spices and limiting your fat intake.

   

2.  Vacation   take it !  If you cannot afford the time, then plan a break in the future, maybe a day trip or a long weekend.  Just knowing you have some down time in the near future can help.

   

3.   Alcohol    look at how much you drink, what you drink and why you drink.  Is it purely social, or do you use alcohol to wind down?  The 'moderation' comes in here, be sensible and choose your poison wisely.

   

4.   Compromise.  Sometimes you have to.  If you are deadlocked with someone just as thick skinned as yourself then look for some middle ground.  Take a time out, don't let anger drag you into a battle that need not happen.

   

5.   Your own space.   Make a space your space, it could be a room in the house, it could be the garage or the garden.  For those that work at home it sometimes gets overwhelming, your home is no longer your retreat its just one big office.  Find a space, put some favorite things in there - books, TV, music, plants, whatever it takes for you to make your mark, then make it off limits to everyone else.  Try to get into your space several times a week, even if its only for 15 minutes and DON'T take your cell phone or your pager.

   

6.   Communicate.  OK so those at work may not want to hear about your stress, but some people can help and when asked they feel special and are usually more than happy to help,  Show them your list if need be or simply explain that all the demands made on you are wearing you down.  If it is a partner and if they are also a cause of some of your stress, explain the whole picture, how overwhelming it is and ask for their compromise and understanding.

   

Now we should mention here that once you communicate your stress with a partner then you could be opening the flood gates.  It is a two way street, you may be oblivious to stress in their life.  If so ask them to write down a list, sit down together and see where you can help each other.  How apt is that saying "A problem shared is a problem halved."

   

7.  A pet.  Research has proved that having a pet can be a great stress reducer.  Obviously stress should not be the sole reason for getting a pet, but there are benefits to having a companion that doesn't talk back.

   

Living a stressful live is not conducive with living a happy life and as a scientist at Duke University Medical Center pointed out "a man living in this constant state of stress is unpleasant to be around, but absolutely lethal to himself."

Protein and the Kidney Monologue

Credit: CharlesPolquin.com and Jose Antonia, Ph.D.

By Jose Antonio, Ph.D.

One of my close friends is a professor at a fairly high profile Midwestern university (he'll remain anonymous so as to avoid the wrath of his fellow protein-hating colleagues) and we were talking recently about how grossly misinformed many in academia are regarding dietary protein intake.



This is what you'll often hear in the ivory towers.

"High protein diets are bad for your kidneys."
"Protein dehydrates you."
"Athletes get plenty of protein in their normal diets."
"Protein is evil."
Okay, maybe the last one is an exaggeration; albeit a slight one.

For whatever odd reason, some of the most educated individuals are also some of the most misinformed when it comes to dietary protein. First, let me set the record straight.

There is no evidence that high protein diets (which I'll operationally define as 2-3 times greater than the ridiculously low RDA) is harmful to otherwise healthy individuals.(1)
There is evidence that in individuals with renal dysfunction may need to consume protein that even exceeds the RDA.(2)
The addition of protein to a sports drink does not dehydrate you and may in fact improve performance and recovery.(3)
Athletes do need more protein than couch potatoes.
Protein is not evil. (Sorry, no references).
What the heck is protein anyway?
Just as glucose serves as the building block of glycogen, so are amino acids, which are the building blocks of proteins. Proteins are arguably the most important component of your cells.

They're involved in formation of contractile tissue or muscle, they make up a large part of the structural component of cells, they are a part of enzymes, antibodies, blood, etc. You name it, protein is part of it.

The main function of protein is to provide the needed amino acids for maintaining an anabolic (growth) or weight-stable state. However, recent data shows that additional protein promotes recovery and performance during exercise. (3, 4)

How much protein should you consume?
The easiest way to remember how much protein to consume is via the formula – 1 gram of protein per pound of body weight. Hence, a 200 pound individual needs about 200 grams of protein. And don't be misled by the "carb-Nazis" who pontificate on the impending doom of your kidneys if you consume this much protein. If that were the case, gyms would be littered with strength-power athletes with failing kidneys.
In fact, according to Darryn Willoughby, Ph.D., of the International Society of Sports Nutrition and member of AXL's Advisory Board, "the hazards of eating a high protein diet are as overblown as a big Texas hairdo. Now if you have damaged kidneys then the work that your kidneys need to perform to eliminate excess nitrogen would make it wise to avoid excess protein. Otherwise, enjoy that Porterhouse."

Suffice it to say that the RDA of 0.8 grams per kilogram body weight per day is grossly inadequate for anyone whose activity levels exceed that of a La-Z-Boy recliner. Even though muscle protein degradation or breakdown increases during exercise, there is a significant increase in muscle protein synthesis for at least 24 hours after either resistance or endurance exercise. If you are not getting adequate protein during this time, then it would make sense that you probably will not gain lean body mass.

How much protein can I consume at one sitting?
Great question! Unfortunately, the scientific answer isn't known. But I'll give you the Midwestern common sense answer. Would your 75 year old grandma and the 250 lb, 25 year old martial arts fighter have the same limitations when it comes to digesting and absorbing protein? Obviously, the fighter needs more protein to assist with recovery and repair of muscles.

In all fairness, there are studies in which levels of 30 grams of protein are fed to subjects; and this amount produces a tremendous rise in blood amino acid levels. I'd imagine that 30 grams of protein per meal is a good starting point. If you eat 30 grams a sitting and you eat 6 times daily, that's about 180 grams of protein.

For most "normal-weight" individuals, that should suffice. But imagine if you're a 300 lb football player or bodybuilder? You'd either have to eat more protein per sitting or just eat more meals. The answer to this problem? Consume meal replacement powders as a protein supplement.

Protein and those with real kidney problems – the other viewpoint
A recent paper discussed two of the National Kidney Foundation Kidney Disease Outcomes Quality Initiative (K/DOQI) clinical practice guidelines for nutrition in chronic renal failure.

These guidelines recommended a dietary protein intake of 1.2 g protein/kg body weight/day for clinically stable maintenance hemodialysis (MHD) patients (Guideline 15) and 1.2 to 1.3 g protein/kg/day for clinically stable chronic peritoneal dialysis (CPD) patients (Guideline 16).

If you do the math, that is roughly 50% to 63% greater than the regular RDA or recommended daily allowance. But I thought eating protein was evil, evil, evil? Maybe not.

Scientists suggest that the possible mechanisms that require these increased protein needs include (a) the substantial quantity of amino acids, peptides, and proteins removed by the dialysis procedure and (b) the protein catabolic or anti-anabolic state caused by the uremic milieu, the inflammatory state, the oxidative and carbonyl stress, and the bio-incompatible dialysis materials to which MHD and CPD patients are exposed. In English, that means these individuals tend to be very catabolic and need to somehow replace the lost amino acids or protein. (2)

Protein types – the slow and the fast!
Cool work from France delineated the concepts of "slow" and "fast" proteins. In fact, this may play a greater role in muscle protein metabolism than the older concepts of biological value.

In essence, there are two proteins that many of us consume, which are digested at different rates (hence, slow and fast). In comparing whey to casein protein, whey is a faster protein, meaning it's absorbed quickly into the bloodstream and remains elevated for about 3 to 4 hours. On the other hand, casein tends to clot in your stomach and in essence is "timed-released" such that you have significant elevation of blood or plasma amino acids for up to 7 hours.

Why are these distinctions important? First of all, whey is a very anabolic protein. However, inasmuch as you get a quick rise in plasma aminos, you also get quite a bit of oxidation of the protein (i.e. it is used for fuel). Casein however does not promote as much anabolism but is very anti-catabolic (i.e. inhibits protein breakdown). The "net" effect is that if you do a head to head comparison, casein beats whey over the long haul. Does that mean you should dump that bucket of whey into the trash bin? Hell no.

In fact, take advantage of whey's easy and quick digestion/absorption qualities and consume it as part of your post-workout meal. Casein may be best if consumed as a single meal prior to bed (to sustain plasma aminos throughout the day).(5-9)

Protein and bone health
According to one study, protein intakes do not contribute to the wide variability in calcium absorption efficiency. (10) Or put another way, eating protein probably has no effect on bone mineral content.

Another investigation stated verbatim that "several recent epidemiological studies demonstrate reduced bone density and increased rates of bone loss in individuals habitually consuming low protein diets." (10-12) So, one might argue that low protein intakes is the culprit. Either way, it would be wise to consume both adequate protein and calcium to maintain lean body mass and reduce body fat.

Adding protein to sports drinks
In a recent study that compared a traditional sports drink (water, carbs, and electrolytes) versus a sports drink that contained added protein, they found that cyclists rode 29% to 40% longer when they consumed the sports drink with protein than the one without.

Also, peak post-exercise plasma CPK (creatine phosphokinase) levels, an indirect measure of muscle damage, was 83% lower after consuming the sports drink plus protein. So don't believe the baloney about protein dehydrating you ('cause if it did, these cyclists would not have performed better) or being unimportant during exercise. Even a small amount (~3-6 grams) during exercise might do wonders for you!(3)

The Moral of the Story

Consume 1 gram of protein per pound of body weight daily.
Spread it out over 6 meals.
Protein intake 2-3 times over the RDA is not harmful to your kidneys, bones, or anything else for that matter.
Adding a touch of protein to a sports drink may improve performance and speed up recovery.
Consume "fast" proteins after you exercise and "slow" proteins at the end of the day.
