Shoulder Injury (Part 1)

shoulder

I read a Frederic Delavier’s book « Strength Training Anatomy » and there is good stuff.

Shoulders injuries are frequent in bodybuilding because we want develop all deltoid muscles. To do this, we must perform a signigicant number of repetition and movements thus multiplying the risk of injury.

It’s worth remembering that, in comparison with the solid hip’s articulation where the femur head is deeply embedded in the pelvic cavity of the pelvis, shoulder’s articulation, which must be very mobile to allow arms to move in all direction, is very little embedded.

Shoulders can thus be defined as a joint to muscular fixation, the maintenance of the humerus head on the scapula’s glenoid cavity is mainly ensured by a complex musculo-tendinous ensemble.

Although in bodybuilding most injuries occur during shoulders training, it’s rare to see this muscle directly injured. The wound are generally much deeper and appear most often during a false movement or after a long wear by friction of tendon structure reinforcing the articular capsule.

While in other sports of violent contact (such American football) or rapid arms movements (such as throwers) can result in serious injuries with dislocations and enven tendon pull. The main lesion observed is what we call subacromial bursitis.

Some people when performing elevated arm movements, such as back press or lateral raise, the supra-spinous tendon is rubbed and compressed between humerus head and osteoligamentous vault formed by the underside of the aromion and the coracoacromial ligament.

The result is an inflammation which generally begins with the synovial bursa, which normally protects the supra-spinous tendon from excessive friction. And it continue by the supra-spinous tendon itself and ends, if this inflammation isn’t treaed, by touching the adjacent tendons of the infraspinatus at the back and the long portion of the biceps at the front.

Arms elevation becomes extremely painful and there may be an irreversible deterioration of the supraspinatus tendon with calcification and sometimes even rutpure. The latter being observed in general only with people over 40 year old.

The space between the humerus and osteoligamentous vault can vary from one individual to another. Some athletes will not be able to lifte their arms laterally without generating excessive friction. These individuals must therefore avoid all back press, lateral raise to high and also when they train back, pulldown behind the neck.

All exercices with barbell for shoulders should be done in front of, with elbows slightly forward. With dumbbells lateral raise, the correct working angle should be sought, the right movement being the one that is realized painless.

It’s interesting to note that for the same shoulder injury all individuals don’t respond in the same way. Some people can perform all sort of arms raise, compressing and sometimes even deteriorating their tendons without ever triggering a painful inflammatory process. Thus, in the course of an examination, some people have discovered a rupture of the supra-spinous muscle’s tendon without ever having complained of any pain.

Another cause of shoulder pain may be due to an imbalance in the distribution of muscle tension around the joint capsule. Recall that the humerus head is firmly held against the scapula’s glenoid cavity by a muscular system with tendons adhering or passing through the articular capsule. This set is composed at the front by the subscapular, a little more on the outside by the long portion of the biceps, above by the supra-spinous and finally at the back by the infraspinatus and the teres major muscle. Spasm, hypertonicity or, on the contrary, a lack of tonicity of one or more of these muscles, can lead to a bad position of the shoulder joint. This bad position will be the cause, during the movements of the arm, of friction likely to generate inflammatory pathologies.

Exemple : A contracture or a spasm of the teres major muscle and infraspinatus will cause an external rotation of the humerus head which will generate during the movements of the arm, friction in the front of the shoulder joint. And with the time can injure the tendon of the long portion of the brachial biceps.

It will therefore be necessary to ensure to train in a balanced way all the muscles of the shoulder avoiding all the exercices where one will feel a discomfort, a pain or a friction.

Note : Hand massage or better with a vibrator, as well as electostimulation, give very good results to diminish and eliminate spasms and contractures of teres major muscle and infraspinatus.

I read a Nerd Fitness article  and there is good stuff.

In training, the key of success is to have constantly better results and improve challenges level.

If you repeat the same training everydays, every months, your body will adapt et it will learn to burn less calories and make less progress.

To continue to make progress our body to become stronger, we must constantly add little challenges everydays.

Always do the same thing again and again doesn’t work

same thing

Normaly, if you want to lose weight, you need to increase your energy expenditure. You need to move more, right ?

In summary to lose weight, you must move more and eat less. But move more is a little bit more complex than that.

Exercices don’t always lead to an expenditure of energy. There is a little explanation the New York Times .

Professor Pontzer for Hunter College followed a hunter-gatherers tribe and he learned they burn the same amount of calories than an average american. Mainly, their bodies adapted to the stress and learned to burn less calories in other ways to increase efficiency :

« Energy expenditure is consistent across a broad range of lifestyles and cultures. Of course, if we push our bodies hard enough, we can increase our energy expenditure, at least in the short term. But our bodies are complex, dynamic machines, shaped over millions of years of evolution in environments where resources were usually limited; our bodies adapt to our daily routines and find ways to keep overall energy expenditure in check ».

If you do 3 sets of 10 push-ups everydays, your body will be really good to do 3 sets of 10 push-ups, it will be more efficient but not necessarily stronger each time.

Look :

  • To increase your level in a video game, you need to fight against enemies stronger than you.

  • To increase your level training, you need to do harder challenges in your training.

Progressive overload

progressive overload

We know we can’t do the same thing forever to have huge progress. We need to do challenges.

« Progressive overload », this is our chanllenge’s name. We overload ours current capacities, slowly but surely.

NSCA’s Performance Training Journal  explains :

« Without overload there is no adaptation by the body. Neuromuscular adaption occurs first, followed by increases in muscle and connective tissue, and bone mass. Proper conditioning methods will lead to physiological advancement as well. Depending on the training goals, improvements in lactic acid tolerance, lactate threshold, maximum aerobic power, and a variety of cardiovascular functions could be the appropriate responses ».

Our body will improve in all sorts of ways form stronger muscles to a better performance of the central nervous system. All of this is possible with a stimulus or simply « a challenge ».

We apply a stimulus to our body and our body responds, this improve all these areas mentioned above.

The solution is simple, right ? Just increase the challenge to each exercice, everydays and forever. Just to reach the level 99.

A record everydays

I wrote an article to break a plateau  and the better thing to break a plateau is to avoid it. A plateau can drain mentally, depress and can demotivate the most rebel.

When a linear progression is no longer possible, it’s the time to make little progress each week. This allows to progress without injuries.

Here are the benefits of this approach :

  • You don’t overload too much your body but you learn to lift more weight each week then your body begin to adapt to become stronger and repairing properly.

  • You don’t have these days where you feel blocked. You proves to yourself constantly than you’re better than yesterday.

The goal is to increase the total weight you lift in each training somehow. There are several ways :

  • Lift more weight per reps than the last time

  • Do more reps with the same weight than the last time

  • Lift more tota weight than the last training

  • Do the same number of reps, same number of sets and the same weight, but with less rest time between sets.

  • Lift in a better form with more range of motion or a harder variation.

As long as one of these metrics is higher than your previous training, you’re improve your level et you are stronger.

Example :

  • Training 1 : 5/5/5 x 43kg (95lbs)

  • Training 2 : 6/5/5 x 43kg (95lbs)

  • Training 3 : 6/6/5 x 43kg (95lbs)

  • Training 4 : 6/6/6 x 43kg (95lbs)

Each weak ONE rep was added in the training. Then for the Training 5 and 6, the processus restart with a heavier weight.

  • Training 5 : 5/5/5 x 45kg (100lbs)

  • Training 6 : 6/5/5 x 45kg (100lbs)

The total weight lifted in Training 4 is 3x6x43kg = 774kg (1706lbs) and the total weight lifted in Training 5 is 3x5x45kg = 675kg (1488lbs). There is more weight per reps, there is progress, it’s cool.

Slow, stable, constant progress. Little by little, we become less little !

You ? How you progress ?
