Sudden cardiac death (SCD) is an extremely rare event. The most common reason for cardiac death related to sports is the cardiomyopathy hypertrophic, an abnormal enlargement of cardiac muscle. It’s a rare heart disease that predispose a person of SCD because of physical exertion.

Commotio cordis is another reason for SCD. It’s a direct trauma to the chest at a specific moment in the cardiac cycle and this trauma triggers a dangerous arrtyhmia (abnormal rhythm) of electrical system of the heart. A commotio cordis usually arrives in sports where a blunt projectile, such as baseball ball or hockey puck, hits the athlete’s chest.

Treatment

Cardiac arrhythmias that threaten the lives of young athletes are very difficult to treat. The immediate use of AED (automated external defibrillator) can provide an advantage.

Unfortunately, the only way to prevent death from hypertrophic cardiomyopathy is to identify the disease and recommend the athlete avoid any strenuous activities. Cardiac ultrasound can diagnose this condition. Some experts have called for the screening of athletes with ultrasound or electrocardiograms (EKG), although this screening is controversial because of the high cost and scarcity of this condition.

However, athletes with cardiac symptoms such as dizziness, fatigue, shortness of breath in relation to physical activity, palpitations, convulsions and especially syncope (fainting) must stop the competitions and must do deeper tests.

In addition, a family history of cardiac abnormalities justifies a complete cardiac evaluation. Especially a known parent with hypertrophic cardiomyopathy or a history unexplained sudden death in a family member.

There is the creation of different forms of protection for the chest and pads, but unfortunately no method has prevented this tragic event. The rules regularly change in the sport and some times to try to avoid commotio cordis. For example in baseball and softball, it’s the limitation of the use of aluminium bat. This rule can protect the pitcher by decreasing the speed of the ball after contact with the bat. There are other rules too, such as using a softer ball and teaching players to turn their chest when the ball is hit by the bat.

Stats

  • Fortunately, SCD is extremely rare in the sport. For the majority of people do sports to cardiac benefits.
  • In young athetes, the most common causes of SCD are 25-30% hypertrophic cardiomyopathy and 20% commotio cordis.
  • Coronary artery abnormalities are the cause of 14% of SCD in athletes.
  • Marc-Vivian Foe, a Cameroonian soccer star had a sudden cardiac death during a match in 2003.

Heat Illness

heat illness

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.

Every summer, hundreds of people experience sun-related illnesses and heat. Being prepared and hydrated avoids theses situations.

Why

When an athlete exercises, his/her body temperature increase and the body sweats to cool the body. During this process, body fluids and electrolytes are lost. If the boy is not recharged with fluids and electrolytes, it’s dehydration and it increase the risk of heat illness as a heat stroke.

Symptoms

Symptoms are :

  • Chills

  • Dark colored urine

  • Dry mouth

  • Headaches

  • Thirst

  • Weakness

If the heat illness progress, there are more serious symptoms like :

  • Difficulty breathing

  • Body temperature increasing to dangerous levels

  • Muscle cramps

  • Nausea

  • Tingling of the limbs

  • Death

How to prevent

The most effective treatments for heat illness are :

  • Proper training for the heat

  • Fluid replacement before, during, and after exertion

  • Appropriate clothing (light colored, loose fitting and limited to one layer)

  • Early recognition via direct monitoring of athlete by other players, coaches and medical staff

  • Monitoring the intensity of physical activity appropriate for fitness and how an athlete has acclimated to conditions.

  • If possible, having an athletic trainer on site during events and practices to properly prevent and treat heat illnesses.

In situations where the training program is intense or during a trip in a hot climate, an athlete should limit the intensity and duration of the training session. Thereafter, the athlete will increase the training’s intensity for a period of 7-14 days to allow to the body, the time to adjust to the climate and environmental conditions. For athletes with respiratory, gastrointestinal or other diseases, they should especially evaluate these new conditions.

When an athlete should hydrate

hydrate

It’s necessary to hydrate before, during and after a training session. Drinking 47cl (16 ounces) of water is recommended 1 hour before exercises. Hydration should continue with 11-23cl (4-8 ounces) of water every 15-20 minutes throughout the effort

There is a trick to track the hydration’s level is to weigh before and after a physical activity. If the athlete is lighter after a physical activity, this means that there a deficit of fluids (indicated by weight loss) and it’s necessary to recharge them. For the next physical activity, it will be essential to drink more to evaluate the losses (perspiration). An athlete who loses more than 2-3% of his/her bodyweight during exercise may decrease the performance and the body’s physiological function.

If the athlete is heavier after a physical activity, it means that there is a surplus of fluids (indicated by gain weight). For the next physical activity, it will be essential to drink less to evaluate the surplus.

How to treat it

When you see signs of heat illness or heat stroke, it may be an imminent danger of death. It’s necessary that a person immediately call for medical assistance while you’re cooling the person at risk.

Treatment included :

  • Getting the athlete to a shaded area

  • If it heat stroke, cool the athlete rapidly using cold water immersion. If immersion is not available you may use spray from a hose, cold water sponging, or placing cold towels over the entire body

  • Monitoring body temperature

  • Providing cool beverage if possible (i.e., if the athlete doesn’t have altered consciousness).

  • Getting medical assistance as soon as possible.

Heat exhaustion is a type of heat illness that can happen after several days of exposure to high temperature and improper or unbalanced fluid recharging.

Statistics

  • Heat stroke is a type of serious illness related to heat. It can cause death to athletes and this is probably the leading cause of athlete death during the months of July and August.

  • The body produces 1.8 liters (a half of gallon) of perspiration to cool the body every hour. If there are not enough fluids or the heat is overwhelming the body, the person may develop heat-related illness.

Future Past

future past present

I read a Nerd Fitness article  and I learned good stuff.

Past

the past

All that we do in the past is done. The past passes and we can’t change anything. No, no, not like in the movie « Back to the future », no.

All that we do in the past shouldn’t be forgotten so that we can learn. Learn by asking the question : « What didn’t go well ? ». Our past created by our choices and our habits.

For good times, we need to keep it as an emotional memory without living in the past.

For bad times, we need to keep this for not doing the same thing in the future.

Future

the future

The future isn’t yet here. We worry for it destroys hope.

We have hope in the future. The hope is an excellent good thing, the best thing.

We can plan our future and always adjust our plans when necessary.

Tomorrow is a new day. If today is a bad day, tomorrow will be better.

Tomorrow isn’t guarantee. Death can take good people.

Present

the present

Today, a new lifestyle can begin until death. When we choose, choose wisely.

We can do something that usually we don’t do. A new experience makes us become more mature.

We may not do something unhealthy that we do everyday. Change is a good thing.

We can take a better decision than yesterday in our life, our love, our health and our finance.

We can be better than yesterday.

We can do something today instead of tomorrow.

Today is the only thing we can control.

Fitness History – United States (1865 – 1900) Part 9

united states post civil war

United States – Post Civil War

united states post civil war

One of the most important events regarding the modern fitness in the United States was the industrial revolution that led to cultural changes in the country. The advances in industrial and mechanical technologies have replaced labor-intensive jobs. Rural life changed to an urban life. The life of the new city generally required less movement and work than rural life, which has led to reduced levels of physical activity.

At the turn of the century, the most common causes of death were influenza, polio, rubella and other infectious diseases. The risk of illness and death from infectious diseases were relieved by the discovery of Penicillin. The cost of industrialization and urbanization has become obvious in the 1950s and 1960s. An epidemic of hypokinetic diseases including cardiovascular disease, cancer and type 2 diabetes, never before prevalent, began to be recognized as the main causes of illness and death. The improved lifestyle brought in part by the industrial revolution also brought with it an unwanted and alarming cost to health.

Physical education

united states post civil war

After the end of the civil war in 1865, Swedish and German gymnastics experienced an average growth in popularity. However, the most popular form of gymnastics during this period was « The New Gymnastics » introduced by Dioclesian Lewis. Individuals who played an important role in the development of fitness during this period were Edward Hitchcock, William Anderson and Dudley Sargent.

Hitchcock knew the results of its fitness programs (combination of differents gymnastics) to improve health. He also introduced the concept of using anthropometric measures to assess progress in fitness. Sargent added scientific research to teaching fitness and developed organized teaching methods for instructors. Anderson’s work focused on physical education instruction was the development of fitness in a professional organization.

An interesting argument developed during the post Civil War period, still exists today. Several physical education instructors believed strongly in the value of incorporating exercise programs that would improve health-related fitness. However, sports were also gaining popularity in the United States during this era. Therefore, the majority of physical education programs were focused on sports and games. The debate between health-related fitness and skill-related fitness physical education programs continues to exist.

That’s all for today. Soon the rest of the fitness history
