Carbohydrate loading

When most think of carbohydrate loading, the classic method of low carb consumption coupled with bouts high intensity exercise followed by a high intake of carbs a few days before competition comes to mind. The result, according to the theory, is super-compensation of glycogen storage in the muscle cells and liver. The theory holds that one must deplete their glycogen stores prior to consuming or loading carbs in order to facilitate super-compensation.

The average person’s total amount of muscle glycogen is approximately 300 – 500g depending on their gender, size, and level of training. The liver stores between 60 and 120g. A linear relationship exists between the depletion of muscle glycogen and fatigue during exercise. With less glycogen to produce glucose, hypoglycemia begins to affect the athlete. Typically, a person with a blood glucose level below 70 will start to feel light headed, lethargy, and have cold clammy skin. A highly trained athlete, on the other hand, can train at much lower levels than 70 for long periods of time.

As with all training topics there is conflicting evidence on what is the best method to achieve super-compensation of glycogen stores. studies are reporting similar results to the classic method, which so many athletes swear by, without carb depletion, while tapering their training (1,2,3). One thing is for sure, carbohydrate levels play a key role in training and competition success.

In order to figure out what works best for you, try different methods and keep a detailed journal. We all process carbs the same way, but we metabolize them at different rates. Keep mind, studies on training are by no means the end all be all. There are too many variables in most training studies to be reliable. Athletes, especially endurance athletes are over-trained. It is my opinion that athletes who are achieving super-compensation without depletion coupled with bouts of intense training, are doing so because they are over-trained and under-fed before starting the process.

The body is constantly working to stay in homeostasis. Physiology shows us glycogen storage is finite; the body needs a reason to super-compensate. Achieving a glycogen depleted state over a period of time produces an insulin sensitive environment, which is essential for more than normal levels of glycogen storage.

High intensity or high volume?

The question, “What’s best workout for building strength and muscle?” has been the subject of heated debates for years.  My answer is always the same.  There is no one workout that is the best.  There is no one workout that works for all.  However, there are training principles that do apply to everybody.

Anatomically and physiologically we are identical.  A bicep is a bicep and has the exact same function from person to person.  An aorta is an aorta.  Our anatomical structures may have different shapes and sizes, but they all function the same.  This holds true for all tissues in our bodies from blood to hormones.  If this weren’t true medicine could not exist.  How could an anesthesiologist do his job if everybody were different?

Therefore, in order to get bigger, stronger muscles the same stimulus is needed.  That stimulus is short, intense training sessions.  Why short?  Because we have known for centuries the body can either train long or train hard.  A perfect example is to compare distance runners to sprinters.  Because of the types of training, one is emaciated looking and one is muscular.  Remember you can not sprint a mile.  Is it difficult to run a mile, yes?  But it is essentially impossible to run a mile with 100% intensity.

The other factor one needs to take into consideration for building bigger, stronger muscles is recovery.  How much or how often can you train?  Or better yet, how much “should” you train?  Here is where the differences in genetics lie.  Our muscles need the exact same stimulus in order to cause a chain of events that forces them to adapt by making bigger stronger muscles.  However, the rate at which we are able to recover from these intense bouts is as different as the shapes and sizes of our bodies.

So what are you to do?  If you’re training using the typical muscle building routine, which is 3 or more working sets per exercise and 4 or more sessions a week, and not getting anywhere, change it.  First, reduce your sets per exercise by half and only train each body part once a week.  If you still don’t make gains or you plateau after a short while, reduce your sets again.  Remember, if you’re training with 100% intensity and you’re not making gains, you’re not recovering.

More is only better when it comes to sex and money.        

Time equals muscle

A highly overlooked, but very useful tool for progressive resistance training is – Tempo. I will even go one step further and call tempo an essential tool for attaining optimum results from weight training. Yes, it’s true one can attain results performing reps just like every other hack in the gym, but I’m talking about optimum results.

If you’re going to spend the time in the gym, why not get the most out of it. The biggest reason most people who weight train don’t use tools like tempo is shear laziness. Performing a set to momentary failure, to the point where you can’t possibly get another rep is grueling. Few people have what it takes to train correctly, achieving 100% intensity. Hence, the legions of frustrated people in gyms across the US. Like any endeavor, doing your best takes hard work, focus and dedication.

So what is tempo? Tempo goes hand in hand with “time under tension” or TUT. TUT is simply the amount of time a muscle in under tension. To develop the optimum amount of muscle in the shortest amount of time, a set should last between 20 and 60 seconds.

Tempo is the speed of your reps. It is expressed and recorded by three or four digit numbers representing the seconds required to complete a rep. Example: 402 (four, zero, two) or 50X0 (five, zero, explosive, zero). Using the bench press, the first digit is the speed in which the weight is lowered (negative). The second digit is the amount of time one pauses once they’ve reached their chest. The third digit is the amount of time one takes to raise the weight (positive). The forth digit, if used, is the amount of time one takes before lowering the weight again. If an “X” is used, it means explosive, or as fast as possible.

Designing Your Workouts

Is it really necessary to count each rep in order to build strength and muscle? No. Is it necessary to lift under control and to vary your speeds to get the best most rapid gains per your genetics? Yes. When you perform an exercise under control, the muscles are truly doing the work. “Slower”, not “slow” speeds make the muscles work harder by eliminating momentum and bouncing. There’s nothing impressive about performing a bench press by allowing the weight to drop, bounce off your chest and then barely being able to complete the lift.

If tempo is used properly, the target muscle group is truly performing the exercise. Tempo forces one to lift in a very controlled manner, but like any training tool it should be used as an adjunct to your weight training program.

The Good Morning

Bending over to pick something up can be a very dangerous move if done with a rounded back. Most people in their lifetime will have an injury to the lower back. One way to help prevent such injuries is to do the good morning.

Performing the good morning is an excellent choice for strengthening and building the posterior chain, which includes the lower back, glutes and hamstrings. The glutes (butt) and the hamstrings are responsible for hip extension while the muscles of the lower back (erector spinea) are contracted statically.

Because of the large degree of hip flexion, the gluteus maximus and the hamstrings are utilized throughout the movement. The glutes work in unison with the hamstring to extend the hips in the concentric (raising) part of the movement. The hamstrings, located on the back of the upper thigh, become more involved as you begin to decrease the degree of hip flexion while raising the weight. The erector spinea, which run the length of your spine on both sides, are statically contracted throughout most of the movement, keeping the normal curvature of the spine. A static contraction of the rhomboids and the trapezius muscles help maintain the shoulders.

Extension of the body occurs when the upper body, torso and pelvis rotate up and back. The biggest mistake I see with this movement is allowing the back to “round” and magnifying the kyphotic (upper back) curvature while de-emphasizing the lordotic (lower back) curvature. I need to add that a slight curve of the upper back will present no danger and will happen to most while using heavy weight, but if you look like a big question mark (?) while performing the exercise, that’s a different story.

The good morning

Perfect Pecs

Like a great set of developed arms, a well developed chest always gets attention.  Chest and arms are the most frequently worked body parts in any gym across the country.  You never hear of anyone skipping a chest workout to do legs, but frequently hear people skipping their leg workout.  Most of this is due to shear laziness, but some is because chest is much more fun to work.

In their quest for an “Arnold like” chest many people look for that one exercise or that one workout that, like magic, will give them the chest they want.  Unfortunately, genetics, as with all body parts, determines the size and shape of ones chest.  This doesn’t mean, however, that one can’t improve upon what they have.

Do not get caught up in the game of trying to make your muscles look a certain way.  You will consistently be disappointed.  Instead concentrate on making the best of what you’ve got.  You can do this by hitting the chest from a variety of angles.  It is also imperative you “feel” the muscle being worked.  Concentrating on feeling your chest work is as important as performing the exercises. And last, using TEMPO to increase muscle tension is essential and will help to improve your concentration level.

Is performing cardio the best way to lose fat?
There are 3 things to keep in mind about cardio when trying to get leaner. One is that it doesn’t build muscle. Two, it doesn’t preserve muscle while losing weight. Both are extremely important if your goal is not only to get leaner, but to stay that way. As we lose weight the body does not discriminate where the weight comes from. We lose muscle along with fat, especially on a low calorie diet. And performing cardio accentuates this phenomenon.

Lastly, unless you enjoy cardiovascular training, it’s just not worth the time. The work to benefit ratio is dismal to say the least. Unless you’re willing to bust your butt and perform 60 – 90 minutes of cardio a day, which will hinder your muscle building capacity, cardio is not worth it.

KISS for improving soccer performance

These days it’s becoming common practice to start sports earlier and earlier in a child’s life. Soccer is no exception. In the United States the popularity of soccer has exploded along with strength and conditioning camps focusing on sport specific programs. Unfortunately many coaches do not train their players correctly because they do not look at the metabolic demands of the sport.

Research on soccer players has shown, to the surprise of many, anaerobic as well as aerobic power are prerequisites to success. More-over, it’s been reported that 96% of the sprints in a soccer game are shorter than 30m, and 49% are shorter than 10m. It’s becomes obvious that strength and power are important aspects of a player’s development. As soccer becomes more competitive, becoming faster and stronger to get to the ball before your opponent by jumping or sprinting is becoming more important. As a strength coach the question is, how do we develop a player to their optimum ability?

A study by Chelly et al recently reported the effects of a back squat training program on leg power, jump performance, and field performance in junior soccer players. Twenty two male soccer players were divided into two groups a resistance training group (RTG) and a control group (CG). Both groups completed tests before the start of the program and after 2 months of strength training twice per week with heavy loads (80 – 100% 1RM). The tests included a force velocity test to evaluate power, 3 jump tests, a 40m dash, and a 1 RM back half squat. (J Strength Cond Res 2009;23(8):2241-2249)

No significant changes were noted in leg or thigh muscle volume after the 2 month training period between the 2 groups. However, the RTG showed significant improvement over the CG in leg cycling power, jumping and sprinting. This is another example of the value in sticking to the basics. Too many coaches try to reinvent the wheel while training their athletes. There is no need or value in complicated, high volume strength training programs. KISS, Keep It Simple Stupid and train according to the athletes needs

Sex differences in the gym

Weight training can elicit numerous benefits including injury prevention. However, weight lifting has it’s share of injuries and according to a study in Cincinnati Ohio, which examined a sample of 3713 patients, these injuries vary between genders. The objective of this study was to examine the differences in injuries associated with strength training in adolescents and young adults.

Comparisons of accidental injuries between the sexes revealed that women had significantly greater odds while strength training when compared to men. Women had higher foot, trunk, and leg injuries, where as men had higher arm, hand, and head injuries. Men had a much higher percentage of their injuries in the form of strains and sprains compared to women, but there was no difference in reported fractures. The trunk was by far the most commonly injured body part for both men (36.9%) and women (27.4%).

The findings of this study show that men are at far greater risk for exertional types of weight training injuries than women. However, women had significantly higher odds of accidental weight training injuries compared to men, which researchers say is of particular concern. Common accidental injuries include dropped weights, improper use of equipment, or tipping over of equipment. Does this really surprise anyone?

Best exercise for building big lats

Over the years it has been well established that performing exercises behind the neck, like lat pull downs, is detrimental to the shoulder joint. The unnatural movement pattern of bringing the bar behind ones head causes external rotation combined with horizontal abduction, which places the shoulder at a great risk of injury. However, when the lat pull down is performed to the front of the head, there is a lower stress on the shoulder joint because of a higher degree of stabilization by the rotator cuff muscles.

Not only is the front of the neck lat pull down (FNL) a safer exercise, but it allows for a great range of motion. Despite the amount of empirical and anecdotal evidence illuminating the possible negative effects of behind the neck pull downs (BNL), proponents tout is greater efficacy for building bigger lats. But Is there a difference in the activity of the primary movers during different lat pull down exercises?

A recent study analyzed the electromyographical (EMG) activity of 3 different lat exercises. The exercises used where the BNL, FNL, and V-bar behind the neck lat pull (V-bar). Twenty four experienced weight lifters participated in the study performing 5 reps with each exercise, with electrodes positioned over 4 muscle bellies (pectoralis major, latissimus dorsi, posterior deltoid, and biceps brichii). Although a previous study (J Strength Cond Res 16:539-546) showed a greater activity of the latissimus dorsi muscle using FNL when compared to the BNL, this was not the case with the present study. (J Strength Cond Res 2009:23(7);2054-2060)

If your objective is to build bigger lats, than any of the 3 exercises in this study can be used with equal activation. However, with no advantage being found in this or any other study to date performing the BNL, one should question it’s use. There is no movement in sport or daily activity that the BNL mimics. Conversely, the FNL mimics movement patters in sports and daily activities helping to reduce injury and improve function.

There are a few concerns I have with this and previous studies analyzing prime mover activation in lat exercises. The distance between the hands, which were the same for this and other studies, has a huge impact on the range of motion, the load used, and EMG activation. The closer the grip one uses performing a lat pull down, the greater the range of motion and load, which consequently yields a greater activation of the prime movers.

Changing exercises alters movement patterns and muscle recruitment, which can increase or decrease the load used. A greater load, which elicits a greater EMG activation, can always be achieved with movements to the front of the neck as opposed to the back of the neck. For this reason, using the same load for all 3 exercises doesn’t show the true ability of an exercise to activate target muscles. The correct load used would be such that each exercise was performed with maximum intensity. Only then can there be an apples to apples comparison.
