Amino Acids Between Meals Aid Muscle Growth

Thursday, February 26th, 2009

In order for muscle growth to occur, the body must be in a positive nitrogen balance. This means that more nitrogen must be coming into the body than going out. So where do you get the nitrogen? Well, amino acids are basically the only source of nitrogen for the body. (Note: Amino acids are the building blocks of protein.) Therefore, consuming an adequate and constant supply of amino acids throughout the day is always in the best interest of any athlete and one of the reasons why we consume 4-8 meals a day. However, due to hectic lifestyles, eating a meal isn’t always an option. This has lead many athletes to supplement their diet with amino acid blends and/or protein supplements between meals. Results from a recent study showed if there was any benefit in doing this.

Subjects in a study conducted at the University of Texas were split into two groups. Each group consumed 3 meals a day (at 8:30, 13:30 and 18:30) with the total caloric intake for each subject based on the Harris-Benedict equation. However, one group consumed a supplement blend containing 15 g of essential amino acids and 30 g of carbohydrates 2.5 hours after each meal. The results from the study showed that the subjects consuming the supplement blend had a greater anabolic (muscle building) effect than those who only ate breakfast, lunch and dinner.

Muscle Building Nutrition Q&A – Part 1

Wednesday, February 25th, 2009

I get asked a variety of muscle-building/bulking-type questions a lot, so I thought I’d just cut and paste a common question and answer it here. My opinions here would not be gender specific and apply both to males and females.

Q: Would I have to do a bulk and how long would I bulk for?

A: Ok, just to put some context to the term “bulk” here, it simply means eating at a caloric intake that is above your assumed maintenance calorie requirements for an extended period of time – with the obvious goals of adding some size and strength to your physique. It is not an excuse to get fat or sloppy.

To address the first question – would you have to do a “bulk?” This is entirely dependent on three primary things:

  • What do you look like now relative to what your goal physique generally looks like? For some, it will be obvious that yes, you definitely need more muscle if you’re going to hope to be competitive. Developing a great physique isn’t just about fat loss. Males or females with great physiques are well-developed with strategically emphasized muscle groups, in addition to carrying low levels of body fat… and yes, the developmental aspect takes time.
  • Do you want more muscle? What are your own goals and preferences for your physique? Some people like the idea of being more muscular than they are now; some people don’t. It comes down to your goals first and foremost. Only you can determine if you want more muscle.
  • Are you willing to gain a least some body fat? Or, are you presently lean enough right now that you can stand to gain a little body fat and not lose your mind?

To the issue of how long, the short answer is it depends. But that’s about as helpful as well, not answering the questions at all. I’ll be back to answer that question next.

Posing Suits Are Not Bathing Suits

Monday, February 23rd, 2009

I’ve seen it a thousand times – realizing his error, he screams to me from the stage as I sit in the stands  “Help me!” It’s the new bodybuilder on stage in his swimming trunks. Granted – far less disturbing than the fat man on the beach in his G-String – but an error nonetheless.

So the debate ensues:  Before you try to pass off a swimsuit as your gear for the day, hold on. While similar in structure and style, there are a few differences you need to know about. And while the thought of wearing such a skimpy piece of clothing on stage may seem embarrassing, losing to the guy who did wear one is even more embarrassing, don’t you think?

Remember that the reason that you are in competition is to show off the work you have been doing on your musculature. A posing suit is cut to show off as much of your leg sweep and help narrow your waist as possible, within current standards of modesty. Sure, there are those who jokingly call them “Daisy Cutters” or “Banana Hammocks” – but these puppies are the necessary tools of the trade. It is not designed for speed in the water like a standard swim trunk would be. While this will go against all logic for most of us, the key feature you are looking for in a suit is exposure. However I cannot stress the following enough! There are limits – and while posing suits are small – anything resembling dental floss is just plain wrong! While some European contests are open to thongs, North America still frowns on “Whale Tails.” And for that, we here at NxLabs are thankful.

Much like a crowd around the urinal in the men’s washroom, stage fright is the last thing you need to worry about during competition. My advice is to practice posing at home – in your posing trunks. The key to this is wearing it a few times before competition to not only help you get the most flattering fit, but also get used to an otherwise humbling experience. A great tip is to buy two suits; one that fits and one that is two sizes smaller. Some competitors can drop over 15 pounds in their last week of contest prep. There is nothing less flattering than a posing suit that has lost its shape.

How Big A Part Do Genetics Play?

Friday, February 20th, 2009

If you’re the type of guy who drops weight without effort, it’s easy to dismiss the concept of somatotyping. There is ongoing debate amongst bodybuilders about how much your body type, be it ectomorphic (e.g. slender athletes like marathon runners or swimmers), mesomorphic (e.g. sprinters), or endomorphic (e.g. powerlifters or strongmen) matters. We believe it’s something you should keep in mind.

As a competitive bodybuilder, you have a goal of packing on muscle and being ripped, while also having a well-proportioned, symmetrical physique. So while some of us can drop fat without even trying, the same people usually have a tougher time putting on muscle. On the other hand, there are people that have the exact opposite problem. This is where knowing your body type and what diet and training strategies have worked for others with a similar physique like your own will provide you with a good starting point to help you reach your goals. That being said, talk to guys in your gym with a similar body type to see what strategies work for them. Also, stay tuned for Episode #3 of the Body Challenge Podcast for further advice on training and dieting for your somatotype.

Creatine Plus Heavy Weight Training Promotes Satellite Cell Proliferation

Thursday, February 19th, 2009

Satellite cells are immature cells that surround muscle tissue. When muscle tissue is broken down during weight training, a cascade of biochemical and hormonal reactions can happen to send a message to a satellite cell to fuse to the damaged muscle tissue. In doing so, the muscle tissue gains the nuclei from the satellite cell, which aids in repair and growth. Nuclei are the brain centers of the cell and are responsible for signaling protein synthesis (new muscle). Danish researchers found that 16 weeks of creatine supplementation along with heavy-resistance training not only increases the number of satellite cells, but also the number nuclei in the muscle.

The Principles of Muscle Gain

Tuesday, February 17th, 2009

Looking in magazines and through the internet, one can easily find literally thousands upon thousands of workouts to accomplish almost any goal. Some are good, some are significantly less so. In reality, if you lack at least a basic understanding of the fundamental principles behind resistance training and physiology, your chance of success is very limited.

Now to be perfectly honest, I myself have and will continue to use programs designed by other people to great effect. Why would I, a so-called expert, follow someone else’s program? Simple, I don’t believe in re-inventing the wheel, and let’s face it, I’m always learning. However, because of my background and education, I’m quite capable of modifying workouts by selecting different movements and/or load variables for example, to suit my body and requirements. If you choose to follow someone else’s program, and there is nothing wrong with doing so, you must be able to recognize how to modify the program to suit you.

Even the most well-designed program will eventually fail to give you results in time if left unchanged, so be willing to modify or abandon the plan if it isn’t working. That being said, in order to make adjustments to any training program you must understand the essentials for program design.

If you take a good, hard look at the various muscle-building/mass-building programs out there, you’ll notice most sound training plans tend to be based on a few proven ideas or concepts. For example:

  • Stick to basic compound movements. Such as squats, deadlifts, overhead presses and bench press.
  • Progression through various means and methods, such as load (weight used), intensity and frequency.
  • Challenge you to lift loads heavy enough to illicit an adaptive response.
  • Recognize the importance of the nervous system (CNS) in muscle building.
  • Utilize the equation Force = Mass x Acceleration (F=MA). Basically – lift heavy, lift fast.
  • Provide enough strategic variation in exercise selection to minimize stagnation.
  • Control fatigue for best results. Remember the old adage “Stimulate don’t annihilate!”

This might all sound complex, but it doesn’t have to be executed as such. A workout I’ve used with tremendous success is based around the standby 5 sets of 5 reps or 5 X 5 volume protocol. Without getting into the neuroscience surrounding myo-fibrous activation, it seems muscle responds to the timed stimulus achieved with this 5 X 5 parameter. Essentially it’s tough to go wrong when planning your volume and intensity when adhering to 5 X 5.

So, a simple but brutally effective workout utilizing the 5 X 5 approach might look something like this:

  • Warm-up (I prefer active mobility bodyweight exercises)
  • Squats
  • Chest Press
  • Bent-Over Rows with an overhand grip
  • Military Press

You should likely try to perform a variation on the above lifts every second workout front:

  • Front Squats
  • Flat Dumbbell Presses
  • Bent-Over Rows with an overhand grip
  • Seated Dumbbell Press

Challenge yourself with increasing loads every week and something this simple should yield MASSive results!

Next week we’ll look at some principles surrounding fat loss and why most people just don’t get it!  Hint: Just say NO to Cardio!!

Whey & Casein Combo Increases Lean Body Mass

Thursday, February 12th, 2009

Whey and casein are proteins both derived from milk. While each type of protein offers a different amino acid profile, they’re also digested at different rates in the body. Whey is digested fast, while casein takes a lot longer, and therefore, considered a slow-digesting protein. Research has shown that whey can spike protein synthesis (muscle building), but only for a short time. On the other hand, casein has been shown to inhibit protein degradation (muscle breakdown) over a long period of time. This has led many bodybuilders to combine the two for better results in muscle growth – a practice that recent research also supports.

In a 10-week study conducted at Baylor University, researchers split 36 males randomly into 3 groups, who were given a different supplement prior to weight training. Group 1 received a placebo; Group 2 consumed 40 g of whey and 8 g of casein; while Group 3 ingested 40 g of whey, 3 g of branch chain amino acids and 5 g of glutamine. The results showed that Group 2 had the greatest increase in fat-free mass.

One Perfect Rep

Thursday, February 5th, 2009

After witnessing the Gong Show last night at the gym, I find it necessary to clear up once and for all when it’s OK to cheat and when it’s not.

  1. When the girlfriend is out of town: NOT OK
  2. On a test you opted not to study for but party instead – the weekend your girlfriend was out of town: NOT OK
  3. When you’ve done 7 reps in a set with perfect form and feel, you could still squeeze one more out to achieve failure: OK

It’s an epidemic that’s plaguing gyms across the world. The bucking of hips, the swinging of shoulders, even the craning of necks. The affliction? Those who think every rep should be a cheat rep. Perfect from when doing an exercise is a rarity these days.

Little does one know that by cheating every rep. you’re risking injury and actually robbing yourself of gains. There is a reason an exercise is done a certain way. It’s time to get your mind away from quantity and focus on quality for a while. Do a reality check. Drop the weights you’re using by half and do each rep. slowly, while you watch yourself in the mirror. Better yet have a buddy or training partner watch you. Are your hands in the correct position on the bar? Are you bringing the bar down low enough to get the full range of motion? Are you putting as much energy into the negative movement as the positive one? And finally, are you breathing with every rep?

This might seem like a checklist for a rookie, but look at the guys around you. The pride of adding an extra plate can come at the cost of form and that will hurt muscle development and can lead to injury. Perfect form beats a loaded bar any day for gains that last. Whether you’re a powerlifter, a bodybuilder, a football player or somewhere in between, it’s all about the right technique first; the weight will come.
