Stress Fractures

stress. fractures, tibia, fibula

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.

A stress fracture is an overuse injury. Human body creates a new bone to replace a bone that has been broken due to the stress of everyday life. This process is done every day to keep the balance. Unfortunately, this balance can be disrupted because of excessive physical training. There are several factors that can prevent the body from creating enough bone and this make microcracking, called « fracture stress ».

The most common factor of fracture stress is an excessive increase in the intensitiy or frequency of physical activity without adequate rest period. Other factors are nutritional deficiencies, mechanical influences, lack of sleep, systemic factors (hormonal imbalance, etc.) and metabolic bone disorders.

There are case of development of eating disorders and/or amenorrhea (infrequent menstrual periods) for some female athletes who are preparing for a competition. These 2 conditions can create a decrease in estrogen that can decrease bone mineral density. This increase the risk of stress fractures.

Stress fractures are often seen in athletes (especially runners) or military recruiting. For an athlete, 1.6km run is 110 tons of force absorbed by the legs. Bones aren’t made to resist this force (energy) so it’s the muscles that have the function of absorbing shocks.

When the muscles get tired, they stop absorbing the forces and eveything transferred to the bones. Stress fractures occur in almost all bones but are more common in lower bone, expecially the tibia. Depending on the type of sport, there’re distinctive stress fractures such as the elbow in throwing sports, the ribs in golfing and rowing, the spine in gymnastics, the lower extremity in running activities and the foot in gymnastics and bascketball.

Diagnosis

Stress fractures create pain in a limited area directly above the tip of the bone where the fracture occurred. The pain is raw because of physical activity and relived with rest. The sensitivity of the bones is the most obvious conclusion to the physical examination.

With regard to X-rays, this isn’t a tool that actually helps to diagnose an early stress fracture because the bone often looks normal and the microcracking aren’t visible. It’s difficult because after several weeks of rest, the bone begins to repair itself and shows a healing reaction or callus on X-rays.

An early stress fracture is usually confirmed by a bone scan or magnetic resonance imaging (MRI).

Treatment

Stress fractures are generally classified as low-risk (will not become a serious fracture) or high-risk (will become a serious fracture).

Low-risk stress fractures usually require a rest period of 1-6 weeks of limited weight bearing activity progressing to full weight bearing may be necessary. Return to physical activity should be a gratual process.

Low impact activities like swimming or biking are recommended to maintain cardiovascular condition when the pain is gone. When the patient can comfortably perform low impact activities for long, pain-free periods, the patient can begin high-impact activities.

High-risk stress fracture have the danger of becoming a complete fracture. For athletes suffering from chronic pain and having normal x-rays results, it’s recommanded to use a bone scan or MRI. High-risk stress fractures should be treated as traumatic fractures (with cast or surgery) because of complications.

Here are tips developed by AAOS to help to prevent stress fractures :

  • When an athete does a new sport activity, it’s necessary to program progressive goals. For example on the 1st day, don’t run 8km but rather increase the distance gradually per week.
  • Cross-training => Alternate activities to achieve the same fitness goal helps to avoid stress fracture injuries. For example to achieve a cardiovascular goal, alternate cycling and running (cycling one day and riding the other day) is excellent. Adding strength training and doing flexibility exercises help improve performance.
  • Have and maintain a heathy diet with foods rich in calcium and vitamin D.
  • Use good equipment. Don’t use running shoes, gloves, etc, very old and very worn.
  • If during physical activity it start to swell or the pain starts, stop the activity right away. It’s essential to rest for a few days. If the pain continue, you should see an orthopedic surgeon.
  • It’s important to recognize early symptoms and treat them appropriately to return to the sport with a normal level of play.

Stats

  • Stress fractures occur less frequently in those of black African descent than in Caucasians, due to a generally higher BMD (bone mineral densitiy) in the former.
  • Women and highly active individuals are also at a higher risk, The incidence probably also increases with age due to age-related reductions in BMD.
  • Children may also be at risk because their bones have yet to reach full density and strength.
  • The female athlete triad also can put women at risk, as disordered eating and osteoporosis can cause the bones to be severely weakened.

Stop To Be Shredded Everytime

black shredded athlete

black shredded athlete

I watched a Jamcore DZ’s video  and I learned good stuff.

Spring is here and I see that everyone wants to be shredded to show off this summer. I think it’s interesting to explain the difference between be shredded or cutting phase and losing weight.

Be shredded or cutting phase comes from the bodybuilding’s field. After taking muscle mass, be shredded allows to show your muscles striated in detail.

People confuse be shredded or cutting phase and a loss of weight. When you do a good weight loss, you lose water and fat without losing muscle mass and bone mass. When you’re shredded or cutting phase, you lower your bodyfat to 5% to see your muscles in detail as a bodybuilder competing.

Please, women and girls, stop saying that you are shredded or cutting phase. Naturally you have more fat than men and that’s normal because it’s to feed the baby when you will be pregnant. Your body programmed for that and that’s normal. For a woman or a girl to be shredded, it’s necessary to take steroids like women who participate in bodybuilding competitions. A clean weight loss is excellent and sufficient for toning and having a beautiful body.

Let’s talk about weight loss. There are plenty of stupid draconian weight loss programs. These programs cause loss of muscle mass, loss of bone mass, slow down metabolism and create health problems. I wrote 2 articles about it, click here  and there for Part 1  and Part 2 .

Wait

body under construction

I agree with this point of view and I think it’s necessary to be patient before be shredded or cutting phase. Wait 5 years before doing your first cutting phase. Make a clean mass gain for 5 years. Jamcore DZ waited 7 years before to participate in his 1st competition. At the 2nd competition, he felt like he was flat net to his competitors. He waited 3 years before participate in his 3rd competition. 10 years to gain muscle clean with a healthy nutrition to have nice muscle mass when he’s shredded.

So wait at least 5 years to have a healty muscle mass gain before to be shredded or cutting phase. Maybe you find that long but see the reasons :

  • 1st reason : Learn and understand how your body works.

  • 2nd reason : Learn the art of patience. You’re going to have trouble but all the best things are hard to get. You will realize each summer with your friends who will show off but your friends are flat. They believe that they have muscle mass but in fact they’re thin and dry and you arrive and BOOOOM !

  • 3rd reason : After 5 years when you’re shredded, it will encourage you for the next cutting phase. You know that you have to rest your body for several years by gaining muscles in a healthy way to have a better body for the next time. I know that there are people who want to be shredded after 2 years but the results are poor : less experience and more muscle loss because there aren’t enough muscles that was built so a small muscle mass visible. Me, the first time I was shredded, I was disgusted, I felt flat because I had a small muscle mass visible.

    It’s depressing and most people when they’re in this situation, they think to take steroids to show off with pictures on social media. This is happening right now on social media.

  • 4th reason : The more you’re shredded, the more you will regress because you lose more and more muscles. When you’re shredded, you lose some of your muscles, this is the process. So if you do this every years or every 6 months, you lose each time a part of the muscles that you have built.

The most common question

ask question

To start, people who tell you that you can do this all your life are liars. When you start training, you do something new to your body several times a week. It’s like a romantic relationship with a girl. It’s beautiful and after 6 months, she starts to piss you off, you start to piss her off and after you breakup. For muscle mass, it’s the same principle. At first you’ll build muscles and you’ll change your composition’s body, it’s normal.

After a while (2-3 years), your body starts to adapt and you stagnate. That’s when you’re looking for a training system that suits you, you focus on muscle isolation during an exercise, you improve your recovery and you evolve slowly. Gaining healthy muscle takes time and you have to accept it.

At the beginning of your training, you’ll lose fat and water and gain muscle at the same time for 2-3 years and then you’ll stagnate. Most of people who gain muscle get fat because they eat too much and don’t do cardio. Cardio all year is important to help control your weight. When I say doing cardio, it means doing cardio at a middle level, not cardio at a high level to be shredded. Doing cardio while you’re gaining muscle helps you progress because you keep a metabolism that works.

Abs Stretching

abs stretching anatomy

What’s up ? This is THE stephane ANDRE ! I read a Frederic Delavier’s book « Strength Training Anatomy » and I learned good stuff.

Lying on your stomach on your hands with your arms extended :

  • Straighten up your chest slowly by tilting your head back slightly

  • Maintain this position for few seconds while breathing slowly to feel the stretching of your abs.

Variant

It’s possible to make this movement with your hands on a bench and your feet on the floor, or you’re lying on your back on a big ball (Swissball).

Note

Stretching of abs can be an important element in some sports like throwing sports, especially the javelin. In this type of sports, it’s essential to have good flexibility and a good abdominal amplitude to make the movement perfectly.

Attention

Abs stretching are to be avoided in case of lumbar pathology.

Note

The position tilted forward (anteversion) of women’s pelvis allows a portion of the child’s weight to be transferred to the abs. By analogy, abs muscles can be compared to a « hammock ».

Seated Machine Hip Abductions

seated machine hip abductions

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

seated machine hip abductions

Sitting on the machine :

  • Force your legs apart as far as possible

When the machine’s seat is inclined, it’s gluteus medius that works. When the machine’s seat is slightly inclined or vertical, it’s the upper part of the gluteus maximus that works. The ideal is to vary the torso’s inclinaison in the same set.

Example

10 reps with your back glued on the machine’s seat and 10 reps with your torso leaning forward.

seated machine hip abductions variations torso forward

This exercise is excellent for women because it tone the upper part of the hip. It gives the buttocks a rounded appearance, making the waist look slimmer.

Proteins And Kideys

protein

I watched a Jamcore DZ’s video  and I learned a lot of stuff.

When I started to train in a gym. I often asked myself this question : « How much protein do I have to eat at each meal ? ». I asked this question to people in the gym and I had several different answers. For example, someone told me that if I ate too much protein, it could destroy my kidneys or that whey (shaker) was better protein than protein from food (chicken, beef, eggs, etc).

I think you also ask yourself this type of questions so I will help you understand better.

Firstly, everyone knows that protein is very used in fitness and bodybuilding. You can find protein in food or as a dietary supplement such as whey, casein and amino acids. Protein are composed of amino acids.

kidney

1) How much daily protein is recommended for someone who doesn’t do fitness  ?

It’s 0.8 grams (gr) of protein per kilogram (kg) of body weight or 0.36 grams per pound. For this article, I will use the unit of mesure kilograms (kg).

I will take the example of Jamo who is a former professional bodybuilder who continues to train. Jamo weighs 95kg. 95kg at 0.8gr per kilo of bodyweight gives as a result that Jamo eats 76gr of protein per meal. Jamo want to keep his bodybuilder body without steroids. For this, he must eat several times a day and that makes a total of 360gr per day.

2) With sport, do these recommendations change ?

Yes, because a sedentary person will use more of his/her body, which means that this person will use more his/her muscles. The meals content changes with the sport and the type of sport. If we compare a person who is doing fitness and a person doing marathons, we see that the meals are different.

A person doing marathons needs to eat more carbohydrates than protein to have endurance. A person who does fitness/bodybuilding need to eat more protein than carbohydrates for muscles rebuilding and muscle growth.

3) Depending on the intensity, do these recommendations change ?

Depending on the intensity, the answer is yes and no. It also depends on the muscle mass. When a person is doing a really intensive workout, the most important marcro is carbohydrate.

An increase of protein is necessary when a person decreases carbohydrates to be shredded. Increase protein helps maintain muscle mass.

4) With age, these recommendations change ?

change

With the latest scientific studies, we learned that proteins need to be increased with age. When a person start to become old, that person loses muscle mass naturally (and it’s normal). It’s for this reason that it’s important to play sport to maintain muscle mass. And to help to maintain this muscle mass, it’s necessary to increase protein.

This a scientific study about it, click here

5) Consume a large amount of protein destroys kidneys ?

The answer is yes and no. In a case where a person has pre-existing kidney problems before playing sport, it’s important to see a nephrologist (kidney specialist) or a doctor. For people who have healthy kidneys, proteins don’t destoy the kidneys. Kidneys are the most detoxifiying organs of the human body and we (human being) have been created to eat meat. The human being is made to eat a lot of meat. Until now, no study has shown that the protein destory kidneys, except for people with pre-exiting kidney problems.

Here is a scientific study on the effects of high protein intake on the kidneys, click here . This study shows that is a myth and a lie.

6) Assimilation and MPS (mass protein synthesis)

Assimilation is when you eat protein. A part of the protein you eat will be assimilated for protein synthesis. Everything else, your body will assimilate because your body is made of 80% amino acids, so these proteins will be used for your skin, your hair, your eyes, your organs. Absolutely all the protein that you eat will be absorbed by your body, nothing is thrown away. There is no protein in you pee.

The goal of protein synthesis is to repair or eliminate damaged proteins and to build new proteins that are copies of the original. New proteins are stronger, denser and more resistant to stress. Muscle Protein Synthesis (MPS) is the reconstruction of muscle caused by stress placed on the body. This can be an injury (muscle tear) or because you intentionally damage a muscle (lifting weights creating micro tears in muscles). MPS process activated right after micro tears and can last up to 48 hours on a damaged site before being repaired.

A part of protein you eat is used for protein synthesis, which will create the state of hypertrophy with hormones. Protein synthesis doesn’t buid muscle, it’s muscle protein synthesis (MPS).

I just read again my text and I see that it’s a bit difficult to understand (for me too ?!?). To make it simpler, protein synthesis repairs your skin, your hair, your eyes, your organs and create the state of hypertrophy. Muscle protein synthesis repair only your muscles.

Here is a scientific study on nutrition and muscle protein synthesis, click here .

7) Liquid and solid protein

Liquid proteins are whey and casein (shaker). Solid proteins are chicken, beef eggs, etc. The diffrence is that the body assimilates liquid proteins faster than solid proteins. The problem is that the quality of liquid proteins is 75% bad on the market, so it’s up to you to study ingredients (as for food in supermarkets) to find the best quality possible. I wrote an article on this subject, click here

8) Number of grams of protein per meal

  • For men, it’s about 30-35gr of protein per meal. For women, it’s about 20-25gr of protein per meal.
  • For older men, it’s about 35-40gr per meal. For older women, it’s about 25-30gr per meal.

Here is an interesting study for women. Eating a large amount of protein has harmful effects on the bones. Click here .

Boost Your Marketing Based On Science (Part 1)

brain

I watched an Olivier Roland’s video and I learned good stuff.

Let’s see what neuroscience found on things that influence people to buy.

The book of Michel Badoc and Anne-Sophie Bayle-Touroulou « Le neuro-consommateur » (in french)  helps us better to understand this.

It’s a book that has been written for other researchers and academics. This is why this book is very interesting for entrepreneurs and consumers.

Here are the elements from this book to boost your marketing.

Until now, marketing and communication are based on the rational purchasing decisions and perceptions of advertising messages by the consumer. But neuroscience shows us that a huge part of our actions come from the subconscious part of our brain.

For A.K Pradeep  and Martin Lindstrom , only 15% of purchasing decision are rational. Current marketing studies limited in the accuracy of customer behavior. What customers say doesn’t always match what they do. Responses collected during a market study can be influenced by context, which disturbs responses. With neuroscience, we can directly communicate with the brain to try to improve marketing.

Here the elements found in neuroscience on the unconscious behavior of consumers.

  • Age et gender

  • Memory

  • Emotions and desire in the decision

  • 5 sens

  • Cognitive ergonomics, pricing, distribution and sales.

  • Subliminals relationships

  • Community and social networks.

Let’s go, we’ll see that in detail. We’ll start with age and gender because these 2 create behaviors and attitudes, sometimes, difficult to understand by a person who doesn’t belong to the same category.

Age

reptilian limbic neocortex brain

Reptilian brain

It’s the center of instincts and the satisfaction of primary needs. This mainly affects young children. They respect the leader who is the mother or the father but also the strongest person who can protect them in case of external danger.

Limbic brain

It’s the center of stress emotions, instinctive behavior and memory. This mainly influences teenagers. They are mainly attracted by new brands / products and original fashions that can distinguish or oppose them to adult fashions.

Teenagers are often interested in causes or subjects with a lot of emotions : social, humanitarian, ecological, fair trade, etc. They prefer emotional communication over rational information.

neocortex,

It’s the center of anticipation and decisions. This mainly affects adults.

With internet, we can see several big differences in the generational behavior of consumers. There are Digital Native and Digital Immigrants and these 2 categories require different approaches.

digital native immigrant

Digital Natives

These are the people who grew up with computers, smartphone and internet. They prefer to have jerky information without verb and without object complement. They can read in parallel information on several different media. They don’t need to structure their thoughts and they can have a random read mode. They feel emotions much more with colors and designs rather than structured text. They want things to go fast.

Digital Immigrants

They prefer a linear processing of information. They like the text’s logic. They wish to receive the information in a slow way with consistency in the structure. They want to keep their privacy and are wary of the information’s distribution on internet. They sometimes want to work alone.

Gender

gender male female

There is a distinct difference between the behavior of female and male consumers.

Female

The left hemisphere of the brain is more developed in women and they’re subject to the hormones influence. We can see more of this phenomenon when a woman becomes a mother. A woman like to communicate more that a man, she likes to talk and be listened to. She needs shares her ideas, feelings and emotions.

She’s very well oriented in time. A woman is less emotional than a ma but she is more sensitive because she has the sens of smell, hearing and touch more developed than a man.

Male

The right hemisphere of the brain is more developed in man and they’re subject to the influence of testosterone. A man is more emotional than a woman, but he expresses less his emotions. He likes action and competition. He’s very well oriented in space, which allows him to find shortcuts. The man’s view is very developed and is eroticized. This explains why the man is attracted by the nude, jewelry, makeup and clothes.

For these reasons, it’s easier to mee a man’s expectations compared to a woman’s expectations.

Differences

difference

Male

As you can see, man primarily uses his view to select a product or service that he can use to show his strength and seductive power. He likes offers that give short-term profits. He prefers simple and direct communication. He prefers images rather than text. Price is more important for the man than for the woman.

Female

A woman is more complex in her expectations. She processes information in a way that is both rational and emotional. A woman is not attracted by nudity. She is attracted by a neat person with harmonious clothes and neat hands. In the case of a salesman, a woman has no preference for a man of a woman. This is influenced by several elements : voice, smell, facial expression, capacity to listen and quality of answers of the salesman.

A women prefers written and documented communication. She likes social media because she can express her ideas and meet people who share her points of view. She filters rational messages through her emotions. She likes positive communications. Before selecting a product/service, she will compare it with competitors and get information with her friends, co-workers and other people with experience.

A woman is less impulsive than a man even if a purchase can serve as an antistress. For a woman, the touch’s quality and the smell can influence a purchase like clothes.

This is the end of the 1st part.
