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

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.

The Importance Of Counting Calories

count calories

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

As you already know, food is our energy. The energy from food, we call it calorie. Calories composed of macronutriments : carbohydrates, proteins and lipids.

Count the number of calories

count calories

With carbohydrates, proteins and lipids, we can know the minimum number of calories we need to consume, it’s the Basal Metabolic Rate (BMR). Basal Metabolic Rate (BMR) is the number of calories your body needs to function without doing any physical activity. That’s the number of calories you burn while you stay in bed all day.

With your Basal Metabolic Rate (BMR), you can find your Total Daily Energy Expenditure (TDEE) . Total Daily Energy Expenditure (TDEE) is the number of calories your body needs in a day when you train.

Total Daily Energy Expediture (TDEE) varies according to your level of activity during the day (the intensity of the tasks you have to do during the day and the intensity of your training).

Total Daily Energy Expenditure (TDEE) is always dynamic because it’s influenced by the Not Exercise Activity Thermogenesis (NEAT). Not Exercise Activity Thermogenesis (NEAT) is the number of calories you burn in a day when you have no workout. But attention, it doesn’t count the calories you burn when you sleep and eat. It only counts the calories you burn when you walk, read, write, work, study, etc.

As the intensity’s level of your tasks that aren’t a sport activity changes all the time, it changes your Total Daily Energy Expenditure (TDEE) all the time. Here are 2 scientific studies to better understand the Not Exercise Activity Thermogenesis (NEAT), here and there .

Now that you’ve seen your Total Daily Energy Expenditure changes all the time, you need to know that it changes your caloric deficit when you want to lose weight (be shredded) and your caloric surplus when you want to gain muscle.

Lose weight or gain muscle

weight lose muscle gain

The phase for losing weight (be shredded) and gaining muscle influenced by 2 things : morphology (endomorph, ectomorph and mesomorph) and genetics.

Take the example of an endomorph person. An endomorph person is a person who can easily store fat because, it’s a person who has greater resistance to leptin. Leptin is a hormone that manages your metabolism and your appetitie (leptin controls your feeling of satiety). An endomorph person who has this type of information has good tools to know how to manage his/her Total Daily Energy Expenditure (TDEE).

For my case, I’m a mesomorph person. Which means that I’m a person who is losing weight fast and gaining muscle fast. At first, I didn’t count my calories because it easy for me to maintain a good physique. But since I’ve been studying my body to find out how it works, my results are really better for the long term.

That’s why no matter what your body type, I advise you to take the time to count your calories to have the best body possible in the long term.

I use an app on my smartphone to count my calories (you can scan barcodes). It’s My Fitness Pal. Try it, it’s really helpful.

If you intentionally don’t take care of your health, accidentally, you will have an illness.
