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.

How To Do Straight-Arm Lat Pulldowns

straight arm lat pulldowns

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

Podcast

Standing in front of the machine with your feet slightly apart. You take the bar with a pronated grip and your hands’ position are wider than your shoulders width:

  • Having your back straight and squeeze your abs. Inhale and bring the bar down to your thighs with your arms stretched (or your elbows slightly bent).

  • Exhale at the end of the movement.

This exercise works the latissimus dorsi, teres major, and triceps long head. This exercise helps you to have a stable arm-torso junction.

Note

This exercise is great for swimmers to have a better power stroke. Many international coaches have integrated this exercise into their swimming programs.

Back To The Source Of Human Strength (Part 1)

source

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

When I’m in gym, people tell me why they started to train. There are several reasons, lose weight, gain muscles or to be in shape for a special event. There is a golden rule to have result in strength training, it’s eat clean and lift heavy.

Everybody says it, eat clean and lift heavy but what does that means ? I think it’s time to go back to the source.

Why

why

The life is easier when we’re stronger, did you notice it ? By exemple, to carry bags from supermarket, to carry a piece of furniture, to run to be in time, etc. Everything is easier.

Strength training is extremely efficient to build muscle and burn fat. Whether to lose 6kg (15lbs) or 45kg (100lbs), it’s the same thing.

Strength training help to build muscle and lose fat but it also help to stop or even reverse sarcopenia (it’s skeletal muscle reduction with aging). Train our skeletal muscle allow us to be independant (therefore avoid nursing homes) and live longer.

The profits list isn’t finished yet.

A nice athletic body

Strength training help you keep your muscles while you’re in calories deficience and losing weight.

Strength training allows you to have a better oxygen consumption than aerobic exercices. After training your body needs to make a lot of efforts to recover and return to the normal state so the state you had before the training. Scientific studies have shown that your metabolism‘s level increase for 38 hours after your training.

Strength training increase your metabolism, increase your Resting Metabolic Rate (RMR) because your body needs more calories to keep your muscls than to keep your fat. It’s estimated that for each 4.45kg (1lbs) of muscle, your RMR increase of 30-35 calories.

Improve your health

Strength training help you to improve your balance and coordination, improve cholesterol’s rate, help to control blood sugar, stop muscle loss, improve blood flow, reduces your resting blood pressure, build a stronger heart and increase bone density.

Feel better

It’s clear with strength training you have more self-confidence, your have more energy, a better mood, less anxiety and less stress . It also improves the quality of your thoughts, a scientific study has shown that this increases the cognitive function .

It’s not advisable to do a strength training 1 hour before sleeping. On the other hand to train early in the day helps to prevent sleep apnea  and insomnia.

Prevents diseases and degenerative diseases

You notices that many men and women die because of cardiac disease. Stength training helps to solve problems that are factors of heart disease such as inactivity, diabets, obesity, high blood pressure and cholesterol. Cardiologists begin to advise strength training to people who have heart attack.

Strength training helps to manage and improve the lifestyle of people with clinical depression , cancer survivors , have had a spinal cord injury ,who have recently had a stroke , fibromyalgia , Lymphedema , Down Syndrome , Parkinson’s Disease , Osteoporosis  and Arthritis.

It’s fun

Strenght training helps to reach your goals whether an effective training of 20 minutes to have a good naked body or to do a sports competition. It’s fun to see our progress because it’s like increase level in a video game. If you want to be better in a sport like badminton or rock climbing, strength training is a good choice.

People who shouldn’t train

The only people I’ve found who shouldn’t train are people who have an injury and it’s a break that doesn’t last long. We’re human being and it’s natural to carry things and move. Strength training is recommended for pregnant women , children and teenagers  and even paraplegics .

Obviously, it recommanded to see his/her doctor before beginning a strength training program to adjust the training program.

Basic objections

objection

But I’m too old, it’s not reasonable

When people between 30 and 60 years old tell me that they’re too old, I laugh because it’s a lie. It’s like say : « I don’t have time » and later I see a messsage on Facebook like : « Yestersay, Game of the thrones was epic ! ». Scientific studies have shown that people between 70 and 90 years old had impressive results in 10 weeks .

Other scientific studies have shown that this helps to avoid dementia  and to delay Alzheimer’s .

People who think they’re too old to train are exactly people who should train.

But I just want to be better for a sport and I want to stay fit

Strength training improve your muscle’s endurance, scientific studies have shown it. Resistance exercices help to increases overall muscles endurance , fix nervous system problems and increase activation of motor units within your muscles.

I don’t want to bulk too much

It’s a great strength training’s myth, it’s not in 1 year than you’ll have the bodybuilder’s body no matter wheteher you’re a man or a woman.

For women, here 2 exemples of moms who have become strong and fit without having a bodybuilder body. This is the story of Veronica  and Bronwyn .

Have a the body of a famous bodybuilder doesn’t happen in one night. Naturally we don’t have the amount of homones to have the body of a famous bodybuilder. We need to eat a huge amount of food (8 000 – 10 000 calories per day) and a huge amont of drugs (no, no, it’s another type of pharmacy, it’s true).

I’m fat, I want only lose weight

I’m fat, I want only lose weight

It’s a good reason to start strenght training. By losing weight, you surely want to keep your muscles. I mean, yout want to keep your muscles while you lose fat. With strength training you lose quickly centimeters (inches) in different body’s parts. It’s true that the overall weight loss may seem slow, that’s why is important to track your measurements. With strenght training when you eat with a caloric deficit, it’s increase your metabolism so you lose fat.

It’s boring

What I like with strength training, it’s we can see our progress quickly. It’s like increase level in a video game. I think people get bored when they expect nothing to do between 2 sets. This is why I advise people to have headphones to listen to their own music selection or an audio book to increase motivation.

Muscles and strength training

muscle fiber

Don’t be fancy, it’s interesting to understand how our muscles work to avoid failling into the Matrix’s trap. What I mean is that the only person you gave to impress is yourself and not the others.

It’s our muscle fibers that are small muscle cells that build up our muscles. Our muscle fibers are long, cylindrical and have the size of a strand of hair. Our muscle fibers are composed of myofibrils surrounded by sarcoplasm. I really summarized that but if you want to see it in detail, click here .

We have around 642 skeletal muscles that work together to make move our body. Imagine, when you bend your arm, your biceps contracts and your triceps does the opposite (elongates) to let the elbow bend. Every muscle of your body work as a team to make you move.

We have different type of muscle fibers :

Slow twitch (Type 1 fibers)

Slow twitch fibers are used to convert oxygen into energy for a long period of time. They don’t move quickly to be resistant to fatigue. These are the fibers we use most for marathons.

Fast twitch (Type 2 fibers)

Fast twitch move quickly so they’re not resistant to fatigue. Our body has 2 categories of fast fibers. The type 2A fiber has an endurence characterisitc used for long sprints. The type 2X fiber has « super fast » characterisitc used to short sprints or lift weights. I really summarized that but if you want to see it in detail, click here .

Each individual has a different percentage of slow and fast fibers. It’s for this reason that people are naturally better to run long distances or sprints. It’s funny because we can see it in strength training with people who are better to do sets with high or low repetitions.

It’s the end of the first part and the second part is event more interessting.
