Whey Protein increases Glucose carriers for greater muscle glycogen replenishment. By Veeraj Vic Goyaram

Supplement Research Update

Whey Protein increases Glucose transporters for greater muscle glycogen replenishment
By Veeraj Vic Goyaram
I am very pleased to report this study because it involves Glucose Transporters in skeletal muscle, the same molecules that I do research in.  In this study, researchers from the University of Campinas in Sao Paulo showed how whey protein improves glycogen (stored muscle carbohydrate) replenishment following exercise, allowing improved recovery. They showed that this happens by improved activity of glucose transporters named GLUT4 in a rat model which received whey protein following exercise.

What is GLUT4?
The main transporter of glucose in muscle is Glucose Transporter 4 (GLUT4). GLUT4 is found inside the cell in the resting state of the cell. After a meal or after an exercise bout, these GLUT4 molecules move to the surface of the cell  where they take up glucose from the bloodstream. The fact that exercise can do this is fantastic news for diabetics and exercising individuals because it means better blood glucose control and muscle glycogen replenishment, respectively. If you need more info on the topic please contact me.
In the right picture you can see that the GLUT4 molecules (stained in green) have moved to the surface of the cell following exercise or a meal. This movement allows glucose to be taken up by the cell from the bloodstream. 

What the researchers did
The researchers, Morato and colleagues had three groups of rats fed experimental diets containing  (A) Casein, (B) Whey Protein and (C) Whey protein Hydrolysate. The animals were subjected to exercise protocol (60min of treadmill running at a speed of 15m/min) and then sacrificed 16 hours later. Their muscles were taken out and analysed.

What was found and what are the implications?
  • In rats fed Whey protein and Whey protein hydrolysate, GLUT4 levels on the cell membrane was higher following after exercise compared to rats fed casein. 
  • This increased level of GLUT4 at the cell surface membrane allowed more glucose to be taken up after exercise for better recovery and the replenishment of muscle glycogen used during exercise.
  • This research study shows the importance of taking a whey protein supplement post training although further research is needed in this topic in human athletes and in diabetics because the latter have reduced GLUT4 movement to the cell membrane.
Exercise increased GLUT4 protein levels in the muscle cell membrane in
all rats. However, this increase was more pronounced in rats fed whey protein and whey protein hydrolysate than rats fed casein

Caffeine allows you to get more reps and feel less pain. By Veeraj V. Goyaram

Supplement Research Update

Caffeine: Less Pain and More Gain.
By Veeraj V. Goyaram


In this edition of our Supplement Science Update Bodybuilding Mauritius brings you a latest scientific study which further backs the efficacy of Caffeine as a workout booster. It is interesting to note that most caffeine-performance studies were done with aerobic-type exercise and it is nice to see some studies that concern us, iron enthusiasts. The study I report here was done in people who lift!

Duncan and colleagues from Coventry University in England looked at what caffeine, taken at 5mg/ kg body weight, does to:

a. The number of reps performed until failure is reached.
b. The perception of pain while repping to failure.

Findings:

a. More reps thanks to caffeine: For the four exercises tested (bench press, deadlift, prone row and back squat), caffeine allowed participants to get more reps until failure (19.6±3.7 and 18.5±4.1 respectively in caffeine and placebo groups). 

b. Less pain perceived: the perception of muscle pain was also lower in the caffeine group in all exercises. The the scientists among you I am including this nice little graph below. 

Add caption
Some important lessons:
  • Caffeine is a great resistance training booster. That is why most preworkout supplements have caffeine as the main ingredient. Most of the other ingredients are just for show on the labels. I said most, not all.  
  • Caffeine works by reducing the perception of pain.
  • 5mg/kg of Caffeine may be a bit high for certain people. The authors accept that they must look at smaller doses. You must also experiment to find your appropriate dose. 
  • If you don't have the cash for expensive preworkout formulas (neither do I), get hold of coffee or inexpensive caffeine tablets.

High Protein Diets & Health. By Veeraj Vic Goyaram

Nutrition Science

High Protein Diets & Health
Do they affect your Liver and kidneys?

Researched and Composed by Vic Goyaram
Bodybuilding is full of myths and a common one concerns the health effects of high protein diets. Along the same lines as "Bodybuilding makes the penis small", "Creatine damages the kidneys" and the like, high protein diets have been said to compromise the function of the liver, kidneys, the cardiovascular system, the skeletal system and God knows what else. Shockingly, the medical community have adopted these myths as facts, much to the disregard of scientific literature which proves otherwise. If a bodybuilder presents to a medical practitioner for some ailment, chances are high that his high protein diet will be put to blame. Most nutrition and dietetics books are full of these myths, as well. 

In this article we will attempt to shed some light on the effect of high protein diet on liver and kidney function. 

High Protein Diets and Liver function

The liver breaks down excess amino acids by the process of deamination. Therefore, the more amino acids from proteins consumed in excess of what we need, the greater the burden placed on the liver and the greater the risk of liver damage, right? 

The TRUTH: WRONG! The truth is that there is no evidence that this happens although there is an upper limit to how much amino acids your liver can degrade. That limit is very high anyway. On the contrary, high protein diets that good amounts of BCAAs are useful to treat liver diseases like cirrhosis (Suzuki et al., 2004).  Furthermore, it is a well known fact that unhealthy habits like overindulgence in sugar-sweetened beverages and booze can cause non-alcoholic fatty liver disease (NAFLD) and liver cirrhosis respectively. However, nobody bats an eye and gives lectures to people drowning themselves in these crap. Open a tupperware full of chicken or drink a whey protein shake and everybody loses their minds. Suddenly, your whole entourage turns into hepatologists (liver experts).
High protein diets do not negatively affect liver function
High Protein Diets and Kidney function

A high protein diet increases the output of ammonia which must be excreted by the kidneys in the form of urea. It has been hypothesised, therefore, that a high protein diet is detrimental to the kidneys because of the extra work they are made to do in that regard. People who suffer from renal problems are often placed on low protein diets in order to avoid this "burden" on the kidneys. The big question remains, does a high protein diet affect the kidneys of individuals with NO existing kidney problems?

The TRUTH: There is no evidence that a high protein diet affects negatively affects renal function even at the high intakes common among bodybuilders. Studies have compared bodybuilders consuming high protein (2.8g/kg bodyweight) with athletes consuming moderate amounts of protein and found that no significant difference in kidney function between these two groups (Poortmans et al., 2000).  A high protein intake may affect kidney function in people with existing renal problems but we cannot go further and say that this will also happen in healthy individuals.  Research published this year in the American Journal of kidney disease (Jurashchek et al., 2013) showed that a long term high protein diet does not negatively affect kidney function in healthy adults.

The consensus among medical scientists is that 
"it is uncertain that kidney health is affected by the long term consumption of a high protein diet and that there is no reason to restrict protein intake in healthy individuals"

If your medical doctor still scares you with the dangers of high protein diets then please invite him to keep up to date with scientific research (list of relevant articles below). Even if he asks "whether you know more than him" at least you did your part. 

..Certainly not damage your kidneys if you are healthy
Future articles will look at other aspects of the health effects of high protein diets. If you have any question, drop me a line! If there is anything complicated in whatever I write please also drop me a line. As always I'd be glad to assist.
