MRSA Infections

mrsa infection anatomy

What’s up ? This is THE stephane ANDRE. With my training, I’m interested in biomechanics to avoid injuries. I read « Sport Medicine Media Guide » and I learned some good stuff.

Methicillin-Resistant Staphylococcus aureus (S. Aureaus), or MRSA, is a bacterium that creates skin infections and other types of infections. The first time that MRSA was seen in US hospitals during the 1970s. Recently, there is a new strain of MRSA know as Community Acquired Methicillin-Resistant Staphylococcus aureus, or CA-MRSA, has left hospitals and began to spread in the community.

This is the strain that is prevalent among athletes. The difference between CA-MRSA and Healthcare-Associated MRSA (HA-MRSA) is in their effects. CA-MRSA usually creates skin infections while HA-MRSA causes bloodstream, urinary tract and surgical site infections. This make CA-MRSA less dangerous than HA-MRSA. Another difference is that CA-MRSA is more vulnerable to antimicrobial.

Symptoms

Signs of infections are :

  • Redness

  • Warmth, Swelling

  • Pus

  • Pain at sites where there are skin wounds

  • Abrasions or cuts

MRSA has the ability to spread to other organs in the body and when that happens, symptoms are more severe.

At this stage, symptoms are :

  • Fever

  • Chills

  • Low blood pressure

  • Joint pain

  • Severe headaches

  • Shortness of breath

  • An extensive rash over the body

These more advanced systemic symptoms require immediate medical attention.

Treatment

The 1st choice for treating MRSA skin infection is to use an antibiotic that has been created to kill bacteria with mild side effects. Most early infections with no widespread symptoms can be treated with oral antibiotics. Because of the nature of this decease and antibiotic options, many patients think they’re « cured » after only a few doses and decide by themselves to stop taking the prescribed drugs. However, MRSA is able to re-infect the patient and become resistant to antibiotics used previously.

For moderate to severe infections, treatment may be with intravenous antibiotics.

These infections associated with deep abscesses or boils require open surgical drainage in addition to antibiotic therapy. Most infections resolve in 7-10 days with an adequate treatment despite the fact that a deep abscess can take up to 4 weeks to eradicate the infection by resolving the abscess cavity.

Early identification and treatment of MRSA infections decrease the amount of playing time lost and decrease the chance that the infection will become severe. Skin may be protected by protective clothing or gear designed to prevent skin abrasions or cuts.

Prevention

mrsa infection anatomy

It’s necessary that athletes have good personal hygiene but it must be added that athletes and visitors to athletes facilities must also keep their hands clean by washing them often with soap and water or using an alcohol-based hand rub. The minimum is to have clean hands before and after sports and activities. For example when we use weight training equipment that is shared by all gym members, it’s important to have clean hands after using toilette or when someone is injured taking care the wounds (including changing bandage).

Ordinary and antimicrobial soaps are effective for washing hands. It’s noted that liquid soap is a better option because it’s not possible to share this type of soap compared to bar soap. Alcohol-based hand sanitizer that contain at least 60% alcohol are the perfect choice.

Athletes should shower immediately after exercise and shouldn’t share soap and towels. Washing all uniforms and clothes after each use is important. Athlete should avoid sharing items that are in contact with the skin and avoid sharing personal items as they contact the skin. Fortunately, most surfaces don’t provoke a risk of spreading staph and MRSA.

Athletes who have had MRSA

Several high school, college and professional athletes have contracted MRSA infections. There have already been epidemics among athletes on the same team. A study published in « The New England Journal of Medicine » shows an infection MRSA among St. Louis Rams professional football franchise (USA) athletes. During a single season, MRSA infections were found among 5 of 58 Rams athletes (9 percents) that was tested. All infections developed on areas of the body that are common places for turf injury.

Stats

  • Today, MRSA accounts for about 50-70% of the S. Aureus infections that are present in healthcare facilities across the world.

  • Statistics fro the Kaiser foundation in 2007 indicated that approximately 1.2 million hospitalized patients contract MRSA infections.

  • Serious MRSA infection is still predominantly related to exposure in the healthcare setting, where approximately 85 percent of all serious MRSA infections occur.

  • Fortunately, in children under 18 years old, mortality rates are much lower (1%), even though the number of hospitalized children with MRSA has almost tripled since 2002.

New Record Daily

record breaker

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 ?

Le Retour Du Soulevé De Terre Roumain

romanian deadlift

J’avais arrêter de faire de soulevé de terre roumain quand j’avais augmenté les poids à 90kg + le poids de la barre olympique. Je perdais l’équilibre alors j’avais changé pour faire du soulevé de terre classique.

Après avoir chercher des informations sur internet pour améliorer ma technique, je l’ai réussi avec succès. Je suis super content, 3 séries de 8 répétitions et la dernière à 6 répétitions. Déçu de ne pas avoir fait 8 répétitions pour la dernière série mais bon c’est beaucoup mieux que la dernière fois où je perdais l’équilibre.

En faisant l’exercice il s’est passé 2 choses, à partir de la 6ème répétition ma prise de main diminue. C’est surtout avec la main gauche, je tiens la barre avec le bout des doigts, c’est chaud. Je crois qu’à partir de la 3ème série, j’ai eu une douleur au bas du dos mais uniquement sur le côté gauche alors qu’avant c’était sur tout le bas du dos. Je pense que c’est parce que c’est mon côté faible. Heureusement la douleur a disparu en faisant l’exercice suivant.

deadlift grip

Avec de l’entraînement et en renforçant mes lombaires, je vais pouvoir faire le soulevé de terre roumain comme le squat, EASY. Pour la prise de main, je ne sais pas encore comme m’entraîner à ça mais je vais trouver. Objectif 4 séries de 8 répétitions, propre.

Demain, je passe à un nouveau niveau dans mon entraînement, j’ajoute 2 répétitions à chaque exercices sauf au squat et au soulevé de terre roumain. Ça va être dur mais je vais le faire, j’ai senti cette semaine que sur plusieurs exercices je pouvais faire une série en plus. Peut-être qu’il y aura des exercices où je n’arriverai pas à faire 4 séries de 10 répétitions mais je vais continuer jusqu’à ce que je fasse toutes les répétitions de façon propre.

Ce qui m’excite encore plus c’est que dans 2 mois, le prochain changement de mon entraînement est le changement de poids. Yeah, je vais augmenter les poids de 2 kg mais je te raconterais ça dans un autre article.

workout face

Fais toi un journal pour savoir quels poids tu soulèves et combien de répétition tu fais pour avoir un suivi de ton évolution. Je te conseille de faire ça parce que ton entourage ne va pas te dire tes progrès, ils deviendront jaloux de tes progrès mais ça ne fait rien. C’est toi qui choisi la vie que tu veux vivre.
