What Happens to the Brain When a Concussion Happens

What happens to the brain when a concussion happens?

Inside your skull you have cerebrospinal fluid and of course your brain. A violent impact causes your brain to vibrate and sometimes even bump against the skull bone. If the force is too much, you end up with a concussion. Ironically, the trauma that occurs when the brain hits the skull is often not evident because the damage is on the inside.  It is known as the “Silent Injury” according to Dr. Lovell from the University of Pittsburgh’s medical center which researches concussions.

Once common mistake is assuming that because you didn’t get “knocked out”  the hit to your head was minimal. If you experience vomiting, dilated pupils, loss of smell or taste you should visit with a neurologist immediately. Additional negative symptoms after a head impact are headaches, dizziness or memory loss lasting more than five days or delayed memory of easy questions (i.e. what did you eat for breakfast yesterday morning?).

Four Stages of a Concussion

Impact to the head – The most common causes of concussions are falls, car accidents, impact sports and explosions. The trauma causes force to the head in two directions: linear (forwards and backwards) or rotational (side to side). These forces literally cause your brain to “slosh” within the cerebrospinal fluid and bump up against the skull.

Inflammation – Trauma to the brain can damage neurons, the cells that govern the flow of chemical messengers known as neurotransmitters. In the worst case scenario, those damaged neurons lose control of the neurotransmitters, allowing them to accelerate up to five (5x) their normal speed. The resulting chemical acceleration can cause memory loss, blurred vision, dizziness, headache and nausea.

Hibernation – Your brain’s cortex detects the neurotransmitter imbalance and tries to fix the neurons by calling for a surge of healing glucose. At the same time, calcium neurotransmitters start constricting the blood vessels, delaying glucose from reaching the neurons. Your brain function slows until blood flow returns to normal.

Recovery – Healing the neurons within your brain can take several weeks.. However, if you sustain another concussion during this period, you could suffer permanent damage and a lifetime of headaches and other adverse side effects. Though it is hard for competitive athletes,  staying away from the potential of re-hitting your head, rest & proper nutrition will facilitate the recovery process.

Note: if you experience headaches after hitting your head, DO NOT consume aspirin or ibuprofen (this may increase your risk of brain bleeding); instead use acetaminophen.

Concussion Dangers and Side Effects

In a previous article I outlined what happens to the brain when a concussion is experienced and the four stages associated with a concussion. (Note: if you need a copy of this article, please email me and I will send you a copy of the article). In this article I want to outline the associated dangers and side effects of a concussion.

Defining a Concussion

Research has validated that you don’t have to be knocked unconscious to be classified as a concussion. We now know that a hard hit to the head without losing consciousness can result in damage to the brain tissue and the neurons and nerves embedded within this tissue. Initial symptoms of concussion include, but are not limited to: disorientation, headache, vertigo (loss of balance), nausea and vomiting. The secondary symptoms include, but are not limited to: mood swings, insomnia (not able to sleep), memory loss, inability to talk without slurring, sensitivity to noise and light, sudden symptoms of being clumsy and unable to hold onto things without dropping them unintentionally.

Health Dangers Associated with a Concussion (only made worse by multiple concussions)

You have rattled your brain, extensive research has validated that a second mild concussion shortly after the first can add up to a lifetime of physical disability (troubles with balance, walking, eating, etc.) and cognitive disorders (inability to focus, remember, perceive analyze and blend sounds, delayed processing speed which makes it difficult to take a test, tie your shoes or answer questions).

How to Handle a Concussion

First and foremost, discontinue any more activity – no matter what anyone says (reference the long term complications outlined above)! According to the American College of Emergency Physicians, the following criteria have to be met before a patient is released from the hospital after incurring a concussion:

  • Patient is alert, oriented and able to follow simple commands
  • Patient has no suggestion of skull fracture (which can include some subtle signs, such as bruising around the eyes or behind the ears, blood behind the eardrums, or clear fluid leaking from the nose or ears)
  • Patient isn’t taking aspirin or other anticoagulants (a substance that keeps the blood from clotting)
  • Patient hasn’t had a seizure
  • Patient can remember events up to 30 minutes before the injury
  • Patient is younger than 65 years of age

Ironically, even if you pass the criteria outlined above, the next round of questions stems around the nature of your concussion:

  • Did you fall from higher than three feet?
  • Did you vomit more than once after the injury?
  • Were in a car accident?

If you answer yes to any of these questions, then you need to cat a CAT scan (CT Scan) of your head to ensure that there are no signs of inflammation or swelling. If the CT scan comes back normal, you will need to ensure that someone is with you at your place of residence to wake you up every two hours and ask you simple questions like: What is your name, what is today’s date, when is your birthday, etc.?).

How Long to Wait Before Resuming Training & Racing

This decision needs to be made by a qualified physician and no one else. When you realize that you are making a decision about your brain and your long term health, clearance to resume training and racing needs to be made with medically backed supervision. The reason for this is two-fold. First, the physician is providing you feedback without emotion: your body is either ready to resume training and racing or it isn’t. Second, if your physican is saying that you are not ready to train and race, he/she is keeping you from injuring yourself worse. This occurs as a result of your brain not being clear and the lack of skills necessary to safely train, ride and race: depth perception, ability to process speed, etc. This situation will result in you hitting the ground again and causing not only a delay in your return, but worse, causing more damage to your head and associated bodily functions.

I realize that you love to train and race, but you have to respect the fact that you have only been provided one brain and it is literally the center of your existence – if your brain is injured, the rest of your life will suffer. No puns intended, but think about this…

What An Elevated Heart Rate Means and What To Do If Yours Is Elevated

/0 Comments/in /by

There is a tremendous amount of discussion floating around these days regarding resting heart rate; however, there is little information regarding what an elevated heart rate means to you as an athlete.

What Causes an Elevated Heart Rate? When it comes to the various forms of stress that your body is subjected to on a daily basis, the list is quite long and complex: lack of quality & quantity of food, dehydration, relationships, financial, school, work, quality & quantity of sleep and keeping all of these variables within manageable levels.   One must realize that your brain doesn’t have a filing system for each form of stress, but rather one large file to handle and address the needs of each form of stress. Notice that the discussion of training and racing hasn’t even been introduced to the stress file. When you train too hard or too long too often, the body has to handle yet another form of stress and the residual effects associated (i.e. fatigue, inflammation, tenderness, etc.).

Daily Symptons Associated with High Levels of Stress

Typical symptoms associated with stress include:

  • Decrease in performance (mentally and physically)
  • Increased recovery windows (takes longer for you to recover from your race weekend and  training days)
  • Short tempered, impatient with other people
  • Lack of motivation to train and race
  • ELEVATED HEART RATE!

Long Term Affects of Stress if Systems are Ignored

The concept of Adrenal Fatigue (a.k.a. Epstein Barr or Chronic Fatigue Syndrome) is applied to individuals that have pushed the body (mentally and physically) too long without adequate rest and nutrition to provide the necessary “tools” to rebuild a body that is resilient to stress.

The four prominent external signs of Adrenal Fatigue are:

  1. Inability to sleep through the night (even though you are tired)
  2. Waking up throughout the night with night sweats
  3. Loss of libido
  4. Craving simple sugars

Please note, the body doesn’t rebuild and get stronger unless it has adequate amounts of sleep (to naturally release human growth hormones – HGH) and high quality food (carbohydrates, protein and fat) to rebuild the body from the inside out – literally. The body that you have today is the result of the food and sleep you have provided your body over the last six months. It takes six months to completely “rebuild” your body and create the ultimate performance machine that you want. Think about it this way, to have the body that you want in June, starts in January!

How do you Identify an Elevated Heart Rate? Though this sounds odd, many athletes misidentify what an elevated heart rate actually is (much less what to do when the assessment is correct).

There are two ways to effectively capture your heart rate:

  1. Empty your bladder and lay back down with a heart rate monitor on for 5 minutes
  2. Empty your bladder in a seated position and take your pulse for 15 seconds and multiply by 4 to establish your pulse for 1 minute

The key to accuracy is being consistent on your methodology and consistency. If you are worried about a margin of error, this margin will be essentially eliminated because your measurement methodology is the same over the course of four weeks.

Additional Variables to Maintain:

  1. Maintain a log of your resting heart rate for a minimum of 4 weeks.
  2. Maintain a log of your hours of sleep for a minimum of 4 weeks.
  3. Maintain a food log for a minimum of 4 weeks.
  4. Maintain a hydration log for a minimum of 4 weeks.

NOTE: If you would like a copy of Coach Robb’s Body Analysis Log spreadsheet to document these numbers, email me directly.

How Does Food, Hydration and Sleep Impact Your Stress Levels?

The body is constantly adapting to the load levels associated with training  (specifically volume & intensity).   Here is a breakdown of food, hydration and sleep as it relates to improved health, wellness and ultimately your on  speed.

Food: By consuming raw, real food, you provide your body with the key elements to a stronger and faster body. Through clean eating, you are providing your body the right mixture of carbohydrates, protein and fats.

Carbohydrates provide your body stored energy (in the form of sugar) in the form of glycogen within your liver and muscles.  Protein is the building block to re-building torn down muscle tissue. Fats are a necessary nutrient for your nervous system and the protection of your internal organs.

Hydration: By consuming half of your body weight in ounces of filtered water (i.e. 160 pound athlete needs to consume 80 ounces of cold filtered water on a daily basis to ensure proper daily hydration levels). you will provide your body the necessary volume of water to maintain proper levels of hydration. Please keep in mind that the average body has 96 pints of water within it. Your brain consists of 75% water; blood is 85% water; and muscle is 70% water.

Sleep: When you provide your body a minimum of eight hours of sleep per night, it has the opportunity to slip into deep levels of sleep (referred to as REM Pattern 3 – this stands for Rapid Eye Movement) which is the depth of rest that your body has to experience before it will release HGH  naturally. When HGH is released naturally, the body will become stronger and leaner – the reason why sleep needs to be protected at all costs for maximum recovery and improved speeds on the track.

What Do You Do With Your Training If Your Heart Rate Is Elevated?

If you wake up in the morning and your resting heart rate is elevated, follow these guidelines to help offset the negative effects of stress (of any and all kinds):

– Morning HR is elevated by 1-2 beats, follow your existing training schedule

– Morning HR is elevated by 3-5 beats, cut your training volume in half and keep your intensity levels exclusively aerobic (if should be able to talk and/or sing at this intensity level)

– Morning HR is elevated 6+ beats, go back to bed and focus on clean eating throughout the day. No training of any kind.

Final Thoughts… Your body provides you with four specific external symptoms, not to mention the daily symptoms. By accurately evaluating your daily morning heart rate, you will have a non-emotional evaluation of how your body is dealing with stress. By focusing on consistent and clean eating along with 8-9 hours of sleep, your body will be more prepared to handle the stressors that you are subjected to on a daily basis and in turn grow stronger and ultimately faster!
