Carbohydrate

What’s up ? This is THE stephane ANDRE. With my training, I’m interested in nutrition to stay in shape. I read some advice from Arnold Schwarzenegger and I learned some good stuff.

Carbohydrates are the main source of energy in the body. All carbohydrates are sugars that are molecules containing carbon, hydrogen and oxygen. Glucose is synthesis by plants through the photosynthesis process (using the sun’s energy) or by animals during the glycogen synthesis process. But be careful when I talk about glucose (sugar), I’m not talking about table sugar. There are several categories of glucoses (sugars). Here they are:

Monosaccharides

  • Glucose (blood sugar)
  • Fructose (fruit sugar)
  • Galactose (a kind of milk sugar)

Oligosaccharides

  • Sucrose(table sugar)
  • Lactose(milk sugar)
  • Maltose (malt sugar)

Polysaccharides

  • Plant polysaccharides(starch and cellulose)
  • Animal polysaccharides (glycogen)

The speed of which carbohydrate metabolized are measured with the glycemic index. A high glycemic index (a large increase in serum glucose) indicate that carbohydrates metabolized rapidly. A low glycemic index (a small increase in serum glucose) indicates that carbohydrates metabolized slowly or differently.

What’s cool now I being able to check the gylcemic index of foods on internet. For example, Chinese restaurant rice has a very high glycemic index compared to brown rice or wild rice.

carbohydrate, bread, rice, pasta, potato

Carbohydrates are the easiest type of food to turn into energy for the body. When carbohydrates converted to glucose, glucose circulates in the blood and helps muscle contraction. Glycogen in the muscle and liver stored for future use. A supply of carbohydrates is necessary for an ambitious bodybuilder for several reasons:

  1. Carbohydrates are a basic type of energy. Carbohydrate stored in the muscles in the form of glycogen will allow to train intense and heavy.
  2. Size of muscles increases when the body stores glycogen and water in individual muscle cells.
  3. Carbohydrates in the body have an effect that prevents the body from burning excess protein to create energy.
  4. Glucose is the main source of energy for the brain to be operational. Carbohydrate deprivation can have very negative effects on mood, personality and mental abilities.

There is a reason why carbohydrates are really needed as fuel for a workout. This is because most exercises are anaerobics exercises. Anaerobics exercises are flushed through intense puffs and exceed the body’s ability to provide enough oxygen to sustain the effort. But the carbohydrates structure allows to continue feeding the muscles during an exercise for a short period without oxygen. Therefore, when you do intensive weight training or you run a 100 meter sprint, your energy for these efforts is mainly composed of carbohydrates.

Carbohydrate supplement

carbohydrate, supplement, powder

Intense training creates a demand in the body to replace glycogen and amino acids. Be careful that your body contains enough carbohydrates after training, otherwise your body may start using amino acids (protein) as a source of energy. The period during which the body is in very high demand for carbohydrates is shorter than for proteins. The best results are obtained when you give the necessary carbohydrates to your body about 20 minutes after your training.

This need for immediate replacement of glycogen is the reason why many bodybuilders use a carbohydrate supplement after training with a protein supplement. It’s very useful when you do a strength training with a cardiovascular session (treadmill, stepper or bike). If you do cardio too soon after your strength training, you’ll be depriving your body of carbohydrates. And as you lack energy, your body will quickly use your amino acids (protein) to create the energy that is missing.

Protein (Part 1)

protein, food, chicken, bean, rice, avocado, beef, egg, bean, nut, milk

What’s up ? This is THE stephane ANDRE. With my training, I’m interested in nutrition to stay in shape. I read some advices from Arnold Schwarzenegger and I learned some good stuff.

Your body uses protein to build, repair and maintain muscle tissue. Bodybuilders have a great knowledge of nutrition, especially the protein for building muscle. Since they want to consume much more muscle than the average person, they consume more protein than average.

Your body uses protein to build muscle only if all the necessary amino acids are available. The small problem is that your body doesn’t produce by itself all the necessary amino acids. Amino acids that your body can’t produce are called essential amino acids and fortunately they’re available in foods.

Proteins are made of carbon, hydrogen and oxygen like other macronutrients, but proteins have one more element, nitrogen. Bodybuilders often explain that they have a positive or negative nitrogen balance, which means that they’re in an anabolic state (muscle gain) or in a catabolic state (loss of muscle).

Food and protein

There are foods called complete proteins, which means that they provide all the amino acids needed to create usable proteins. Milk, eggs, meat, fish and many vegetable products have complete proteins. Be careful because these foods don’t have the same amount of usable protein by weight. For example a food that contains 10 grams of protein, your body can use only 7 grams.

Here is a table that shows the amount of protein by weight and the protein’s amount used in your body as a percentage for the most common foods :

Food% Protein by weight% Net Protein Utilization
Eggs1294
Milk482
Fish18-2580
Cheese22-3670
Brown rice870
Meat and flowl19-3168
Soybean flour4261

(Whey is a byproduct of milk that contain much more protein than eggs)

This table tells us that an egg contains only 12% protein by weight. Despite this small percentage, an egg contains an amino acids balance that allows your body to use 94% of it. However, the table tells us that soy flour contains 42% protein by weight. But because of the amino acids composition, your body can use only 61%. This shows us that there is a difference between the protein’s amount in a food and the protein’s amount your body can use.

This is the end of Part 1.In Part 2, I show you that in cases where you don’t have complete protein foods, it’s possible to make combination of food to have the maximum protein used by your body.

Manage Your Carbohydrate

carbohydrate source food

What’s up ? This is THE stephane ANDRE !!! I watched a Jamcore DZ’s video  and I learned some good stuff.

If you want to learn how to manage your protein, click here and for amino acids, click here.

Carbohydrates are the main source of energy for the body. It’s true that we can have energy with proteins and lipids but they provide less quantity of energy.

To put it simply, when you eat carbohyrates, they turn into glucose and then into glycogen. To better understand, I’ll take the example of a gasoline tank. Imagine that the tank is a muscle and that the gasoline is glycogen. Gasoline in the tank helps move the car and glycogen in the muscle helps move your body.

This glycogen is shared in many places in your body : 80% in your muscles, 14% in your liver and 6% in your blood.

Carbohydrate type

 

Most people know 2 types of carbohydrates, slow carbohydrates and simple carbohydrates. There is a 3rd type, it’s fibrous carbohydrate and unfortunately many people neglect them.

Slow carbohydrates :

  • Whole wheat bread / white bread (refined carbohydrate)

  • Whole wheat rice / white rice (refined carbohydrate)

  • Oatmeal

  • Cereals (muelsi is excellent because there are often lipids and carbohydrates that are added like nuts, raisins, etc. ).

  • Sweet potato / potato

  • Whole wheat pasta / white pasta (refined carbohydrate)

  • Kinoa

  • Couscous

Simple carbohydrates :

  • Fruit (fructose)

  • Honey

  • Dextrose

  • Maltodextrin

  • Lactose (it’s sugar in the milk)

  • Cluster dextrin (it’s perfect during your training session because it has a low glycemic index).

Fibrous carbohydrates (vitamin, fiber et minerals) :

  • Vegetables (aspargus, carrot, cauliflower, salad, etc)

Carbohydrate, insulin and insulin spike

insulin spike blood sugar

There is a special relationship between carbohydrates and insulin. When you eat carbohydrates, they turn into glucose, which is a type of sugar, and then glucose is turned into glycogen. Glucose is managed by insulin. Insulin is a hormone created by the pancreas. The insulin’s role is to manage the sugar’s level in the blood. This avoids having too much sugar in the blood (hyperglycemia) or not enough sugar in the blood (hypoglycemia).

The problem is that the majority of people eat any type of carbohydrate anyway and they may quickly get a lot of fat. It’s important to understand that each carbohydrate has a different gylcemic index and this glycemic index will cause different insulin spikes.

Glycemic index

A glycemic index indicates how quickly carbohydrates become glucose in the blood. It’s for this reason that it’s recommended to eat carbohydrate with a low glycemic index rather than those with a high glycemic index.

Carbohydrates with low glycemic index  :

  • Sweet potato

  • Oatmeal

  • Kinoa

  • Sugar free fruit juice

  • Whole wheat rice

  • Whole wheat bread

  • Whole wheat pasta

  • Fruits (apple, orange, cherry, pear, apricot)

  • Cluster dextrin (for your training session)

 

Carbohydrate with high glycemic index :

  • Potato

  • Couscous

  • Table sugar

  • White rice

  • White bread

  • White pasta

  • Cereal (Kellog, Nestle, etc.)

  • Dextrose

  • Sweet drink (soda)

  • Fruit (melon, watermelon)

Here is an exemple of low glycemic index carbohydrates to eat. For high glycemic carbohydrates, it’s recommended to eat them in moderation because if you eat them in large quantities, after several years, you have the risk to becoming diabetic or having other health problems.

Consumption

Always take into consideration your bodyweight and your training’s intensity. There 2 bad situations :

  1. Have a not very intense training and eat too much carbohydrates, which results in having too much fat in the body.

  2. Have intense training and eat a little carbohydrate, which results in being weak.

Take for example :

  • A man who weighs 85kg and is a beginner. In this case, it’s recommended to start with 3.5gr per kilo of bodyweight so 3.5 x 85 = 297.5gr of carbohydrates to eat a day.

  • A man who weighs 85kg and who is advanced or pro. In this case, it’s 5gr per kilo of bodyweight so 5 x 85 = 425gr of carbohydrates to eat a day. As an advanced person, the training sessions are really intense, that’s why you need this amount of energy.

  • A man who weighs 85kg and who wants to be shredded. Let things be clear, it’s being shredded and not losing weight. In this case is between 1.2 ans 2.5gr per kilo of bodyweight so it’s between 102 and 212.5gr of carbohydrates to eat per day.

The carbohydrates amount to eat is to be divided into 4-5 meals a day for ease of digestion. Each meal is balanced in carbohydrates, proteins and lipids.

To be shredded

shredded lean lose weight vs versus

Let things be clear, be shredded isn’t a weight loss. In this situation, leptin must be taken into consideration. Leptin is a hormone that regulates your appetite. When you start to lower your glucides, leptin will aslo decrease and you’ll be hungry. These feelings of hunger are created because of ghrelin. Ghrelin is a hormone called « hormone hunger » because it stimulates the appetite. Ghrelin also affects your insulin and testosterone.

This means that people who too quicly decrease their carbohydrates will fail because the lack of energy will be too brutal. The feeing of hunger will be too intense because the body has not had time to get used to the new diet. This is where nutrition is out of control.

Never reduce carbohydrate to 0. The people who do that, make a diet ketogenic and you have to master this type of diet. The professional bodybuilder is doing this diet for 4 weeks, but they can do that because of chemical aid (steroids) and they have a dietician. The problem is that those who aren’t professional athletes and who are on a ketogenic diet do that because someone told them it was good. That’s why in the gyms there are people who lose consciousness because they don’t have enough energy. You need 50 to 130 grams of carbohydrates, just for your brain, it’s not a simple diet to lose weight.

Chi-Square Test With More Than 2 Categories

tableau chi square test

I have just enrolled in a Data Science course on Udemy  and I learned good stuff.

In this article, we will do a Chi-square test with more than 2 categories. We will use the A/B test « Country » which has 3 categories which corresponds to 3 countries : German, Spain and France. Select « Gender Actual » tab, make a copy with a right-click and select « Duplicate ».

tableau chi square test

Name the tab « Gender Actual (2) » by « Country Actual ».

tableau chi square test

In « Dimensions », move the variable « Geography » over « Gender » in « Columns » to replace « Gender » with « Geography ».

tableau chi square test

tableau chi square test

Here’s how to do an A/B statistical test when there are 3 categories. We’ll start with the classic method and then I’ll show you another way to do Chi-square test with any number of categories.

Let’s start with the classical method. In this case, there are 3 categories so we can’t use the online tool of the previous article. In the previous article we used an online tool with only 2 categories « Sample1 » and « Sample2 ». That’s why we’re going to use another online tool, click here  .

tableau chi square test

In this online tool, we can enter the values without using the total values. That is, we enter only the number of observations in each category. We simply need to enter the values that are on our A/B test. And I’m going to show you how to turn our A/B test into a table. In this way, it will be easier to enter the values in the online tool without making any mistakes.

Go to the « Show me » tool at the top right.

tableau chi square test

Click on « text tables »

tableau chi square test

tableau chi square test

Click on « Swap Rows ans Columns » button.

tableau chi square test

tableau chi square test

Cool, now you have a table arranged in exactly the same way as the online tool.

In the online tool, we will select 2 rows and 3 columns.

tableau chi square test

As we have 3 categories and 2 possible results, we enter our values exactly as in the table we just created on Tableau.

tableau chi square test

Perfect, our table is ready. You can click on the « Calculate » button.

tableau chi square test

tableau chi square test

As you can see, we observe the same thing as the other online tool. There is our indicator « p » value which is less than 5%. Which means there is a meaning.

tableau chi square test

This statistical significance means that these results are valid for the total number of the bank’s clients and not just for the sample of 10 000 clients. We observe similar differences with A/B test « Country » whose results are based solely on the sample of 10 000 clients. We can conclude that in the total number of the bank’s clients, it’s the clients in Germany who are more likely to leave the bank. This is how we do things cleanly.

You saw, this online tool limited by 5 by 5 tables so you can’t use this tool when you have 6 categories or more. But fortunately it’s possible to do Chi-square test with any number of categories. It’s a special method and for you to understand that, I’ll give you a theoretical explanation.

Here we have 3 countries : German, Spain and France.

tableau chi square test

What we’re trying to compare is the clients number leaving the bank in each of these countries.

tableau chi square test

With our basic A/B test based on a sample of 10 000 clients, we obtained 16% for France, 32% for Germany and 17% for Spain. Now the question is : « Do we observe the same results on the total clients number of the bank ? », it means : « In general, does the country have a significant effect on the clients number leaving bank ? ». Germany has the largest number of clients leaving the bank so the idea is : « Why would we need to compare the 3 countries at the same time ? ».

tableau chi square test

If we do an A/B test statistical test with Germany and France and we get a significant difference in the clients number leaving the bank between these 2 countries, then that would mean that in general, the country has a significant effect on the clients number who bank. Indeed, if we find by comparing Germany and France that the Germans are more likely to leave the bank than the French, we can consider that Spain will not change anything. Germans will always be more likely to leave the bank than the French. Maybe there will be a different relationship between Germany and Spain but there will always be a statistically significant difference between France and Germany with a larger number of clients leaving the bank in Germany than France.

Here is a way to confirm that this logic is true. There is a test and the participants of this test are German, Spanish and French. Imagine that this test was done without looking at what is happening in Spain. Now you get the result and you ask yourself the question : « Would the results changed if you added Spain ? ». The answer is « no » because there is no interdependence between Germany, Spain and France. That is, the decision to leave the bank in France and Germany doesn’t depend on Spain. And therefore, it’s quite correct to separate the categories by putting 1 aside to compare the 2 others. And as now we have 2 categories, we can do a Chi-square test with the online tool that we used in the previous article.

So let’s go back to our worksheet and put a country aside to compare only 2 countries. Select « Country » tab.

tableau chi square test

What we observe is that the difference between Spain and France is very small, so it wouldn’t be interesting to do a Chi-square test between Spain and France. It’s more interesting to do a Chi-square test between Germany and France and to prove that there is a statistically significant difference between these 2 countries. This will be enough to conclude that the country has a statistically significant impact on the clients number who leave the bank.

Selects « Country Actual » tab.

tableau chi square test

We will use the online tool of the previous article, click here  .

We will make a copy of « Country Actual » to have a bar chart with absolute values. Select « Country Actual », right-click and select « Duplicate ».

tableau chi square test

In « Show Me », select « horizontal bars ».

Removes « SUM (Number of Records )» from « Columns » and removes « Exited » and « Geography » from « Rows ».

tableau chi square test

In « Dimensions », move « Exited » in « Colors ».

tableau chi square test

We also need total absolute values, which means the total number of men and women. There is a very fast way to get that. Right-click on the vertical axis and select « Add Reference Line ».

tableau chi square test

Then in « Value », click on the drop-down on the right and select « Sum » to have the total sum of the observations.

tableau chi square test

And in « Scope », you select « Per Cell » option to specify that you want the total sums for each category, male and female.

tableau chi square test

Now, we have the total sum at the top of the bars. We will modify labels to have the absolute values. In « Label », we will change « Computation » to « Value » and click on the « OK » button.

tableau chi square test

tableau chi square test

tableau chi square test

Here’s how to enter the data :

For « Sample1 » in #success, you enter 810 because there are 810 people who left the bank. For « Sample1 » in #trials, you enter 5014 because there are 5014 people in total.

For « Sample2 » in #success, you enter 814 because there are 814 people who left the bank. For « Sample2 » in #trials, you enter 2509 because there are 2509 people in total.

tableau chi square test

Here is the verdict : « Sample2 is more successful ». « Sample2 » corresponds to German’s clients and #success is :« yes, the client left the bank ». This verdict means that of all the clients from German are more likely to leave the bank than clients from France. And look, there is something important, it’s « p<0.001 ». This means that the « p » is strictly less than 0.001. As you can see, « p » value is very small, which concludes that the tests are statistically significant.

Ooh, there’s another thing I wanted to show you with the tab « age » with the 2 bar charts in parallel.

tableau chi square test

As you can see, there are many categories (more than 5) because each category corresponds to a 5-year ago group with clients of the bank aged from 15 to 90 years old. This is a lot of comparison but it would be a good exercise for you to find what are the 2 categories to compare that shows that there is a significant statistic difference.

I give you a hint, compare slices from 50 to 54 years old or from 35 to 39 years olds. In fact, you should compare all peer categories where you observe difference on this basic A/B test. Do a basic A/B test with absolutes values. Then do a Chi-square test to check if the difference is statistically significant, I mean, if the result is valid for the total number of bank’s clients.

This is a way to statistically validate the insights we see onTableau. You see, it’s not very difficult and it’s effective. Here is a way to find insights on Tableau and validate them.

Explanation Of The Challenge And Data

challenge

I have just enrolled in a Data Science course on Udemy  and I learned good stuff.

This is the 1st challenge. Use your web browser to go to superdatascience website  to download a data set. In the « Part 1 Visualization » section, click on « Offices Supplies » to download the file « OfficeSupplies.csv ».

data csv file

To organize myself, I created a folder « Visualization » with 3 subfolders. Each subfolder corresponds to the section of « Visualization ». I put the data set « OfficeSupplies.csv » in the 1st subfolder.

data csv file

« OfficeSuplies.csv » is a CSV file. A CSV file is a text file that represents an table but the elements separated by comma.

You can open this CSV file with NotePad++  for PC or with Sublime Text  for Mac.

On the 1st line (column title), we see that we have 6 columns. Each column separated by a comma and the file contains 44 lines.

data csv file

You can also open a CSV file with Excel, OpenOffice  or LibreOffice  to have a table, which is easier to read.

To open a CSV file with Excel, here are the instructions :

  • Open a blank workbook

  • Go to Data tab

  • Click button « From Text » in the general external data section

  • Select your CSV file

  • Follow the Text Import Wizard (in step 2, select the delimiter of your text).

data csv file

This data set contains data from a store that sells office equipment :

  • Order date – date of sale

  • Region – The store is in 3 region (East, Central and West)

  • Rep – salesperson’s first name

  • Item – product’s name

  • Units – product’s quantity

  • Unit Price – price per unit

Each line shows how many sales there were for a product.

The challenge is to help the manager to know who made the most sales per region in the period of this data set. The period of this data set is from July 2014 to June 2015.

The person who made the most sales in each region has a bonus and there are 3 bonus so 1 bonus per region.

It’s will this challenge that we’ll use Tableau Public.

Back To The Source Of Human Strength (Part 2)

source river

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

If you didn’t read part 1, click here 

Hypertrophy

When I started to train, I thought I can increase the amount of muscle fibers with strength training program. The truth is we have a specific number of muscle fibers. We can only increase the size of our muscles fibers, this is hypertrophy.

I discovered that there were several hypertrophies. Usually when people talk about hypertrophy, it’s sarcoplasmic hypertophy.

  • Sarcoplasmic hypertrophy

    This hypertrophy allows you to increase the amount of sarcoplasmic fluid in your muscles. This can increase the size of one of your muscles by 30 %.

  • Myofibril hypertrophy

    This hypertrophy allows you to strengthen your myofibril, the part of the muscle that contracts. This increase the strength of your muscle fibers, build strong muscles and super dense.

  • Transient hypertrophy

    This hypertrophy allows you to increase temporary the size of one of your muscles during and immediately after an exercice due to an accumulation of fluid (I still don’t know if it’s the sarcoplasmic fluid or glycogen) in the intercellular space. This is what gives the effect « the pump ».

To summarize to buid a muscle super dense and strong, it’s myofibril hypertrophy. To have bigger muscle, it’s sarcoplasimic hypertrophy. Transient hypertrophy is temporary and appears in the other 2 hypertrophies during the training.

During a strength training, here is what happens :

  • During an exercice you’ll break muscle tissue. Your body will repair this muscle and it will become stronger. Whenever you break muscle tissue, your body will do this process.
  • When you increase the number of repetitions, you increase the storage of glycogen in your muscle. This is where you muscle gets bigger.

For the training program

Strength training isn’t just lift weights. It’s more interesting and more complex than that.

Here are details :

chart hypertophy starting strength rep 1rm

A little help for this Excel’s table

  • Repetition (Rep) => An exercice is composed of a starting position and an arrival position. A repetition is when you make the movement from the starting position to the arrival position and you return to the starting position. All that make a repetition. For exemple when you squat, the starting position is standing. The arrival position is when your thighs are parallel to the floor and you return to the starting position, standing.

  • X Rep Max => This is the number of repetitions with the heaviest weight you are able to control. By exemple, 1 Rep Max (1RM), is that the weight is so heavy that you can do only one repetition. 10RM, is that you can control the weight successfully to do 10 repetitions. In the 11st, it’s the failure.

With this Excel table, you can have an idea to how you can do to gain stength (myofribril hypertophy) : A low number of repetition and heavy weight. To increase the size of your muscles (sarcoplasmic hypertrophy) : A high number of repetition and light weight.

ATTENTION : This Excel table give us an idea of how to do to reach our goal. It’s not something specific. When you do a high number of repetition to increase the size of your muscle, you gain also a little strength. Our body is smarter than us.

It’s for this reason I never understand girls or women who don’t want to « get bulk », so they do 3 sets of 16 repetitions or 5 sets of 1000 repetitions with a dumbbell of 2kg (4.4lbs).

It’s hard for a girl to bulk, no matter the weight or the number of repetitions, if they want to increase the size of muscles, that’s exactly what they have to do because it would make sarcoplasmic hypertrophy.

Recovery

recovery sleep

I’m sure you’ve already heard that muscles are built in the kitchen, not in the gym.

It’s because when you’re in the gym, you break your muscle fibers. When you’re outside of the gym, your body heals and your muscles become bigger and stronger. So it’s important to take a recovery’s day in your strength training program.

The general rule is to wait 40 hours before to work the same muscle group again.

Remember that your muscles works in team, which means that when you work your chest, you also work shoulders muscles and arms muscles.

Everyone at his own pace to recover, it depends on diet, sleep’s quality, age workout and other items like stretching or massage.

The basis of strength training is 4 days of training per week and one recovery’s day.

Sore muscles or DOMS

DOMS is the acronym for Delayed Onset Muscle Soreness. Sore means that your muscles haven’t recovered to 100 % (hence the « delayed onset »). This can last 1-2 days after your workout and this is normal. The process for your body to rebuild your muscles takes several days after a workout.

It’s normal that you have sore muscle for several days after your first training or after a long break. With each exercice, your muscle gets used to a movement and adapts to the stress caused by this movement so that you have less sore muscles. Stretching helps you to decrease sore muscles.
