Hydration 411

Water [n]: a transparent, odorless, tasteless liquid, a compound of hydrogen and oxygen, H2O. A need in life— especially when the weather is hot. Now that summer is in full swing and sport camps are gearing up, staying hydrated is extremely important. Proper hydration is crucial to keep your body moving, thinking, and performing to your highest potential.

Do you often find yourself reaching for water during practice or games; it’s probably because you are dehydrated. Read on to find tips and information about the importance of hydration as an athlete.

Water and the Body

The average human body is made up of 60% water. In fact, most of the body's organs are comprised on water.

• The brain and heart are approximately 73% water.
• 83% of the lungs are water.
• The skin is 64% water. 
• Muscles and kidneys are 79% water.
• Bones are even comprised of water, sitting at 31%.

No wonder our bodies cannot function properly when hydration is limited! Water is pivotal for performing at your capabilities.

Hydration

Hydration should not be forgotten when exercise, practice, or games end. Exercising in the heat without adequate fluid replacement is a sure way to cause dehydration and land you on the bench, watching your teammates practice or play.

               

“How much water is needed?”, you ask.

Well, that’s the million-dollar question. There is not a definite answer; in fact, total fluid needs and replacement protocols are quite specific to the individual. Sports dietitian, Nancy Clark, MS, RD, recommends that athletes:

·         Drink 2-3 mL of water per pound of body weight at least 4 hours before exercise, practice, or games.

·         Use your sweat rate to determine necessary water during exercise (see equation below).

·         Drink 50% more fluid than lost in sweat after exercise ends.

Calculating your sweat rate is an important step to determine the amount of fluids you need every hour of exercise. Training with your individualized hydration protocol can not only delay fatigue, but also heighten energy and performance against your dehydrated competitors. For best results, work with a sports dietitian or certified athletic trainer familiar with personalized sweat rate calculations and hydration plans.

Hydration and Performance 

Water makes practice and games easier, and helps performance improve. When fluid is taken in the plasma, volume restores near the pre-exercise levels and assists to avoid adverse effects of dehydration on muscle strength, endurance, and coordination. In addition, pre-exercise hydration assists in improving thermoregulation, heat dissipation, and performance.    

Dehydration

Dehydration is shown when the amount of water (sweat) exiting the body exceeds the amount of water (or electrolytes) entering the body. The risk of dehydration greatly increases when practicing in hot, sunny, intense environments. Dehydration can be shown by a number of signs such as:

·         Thirst—first sign of dehydration

·         Headaches

·         Dry skin

·         Bright yellow urine (see urine color chart)

·         Difficulty concentrating

·         Increase in body temperature

·         Muscle cramps

·         Swollen fingers/toes

Dehydration and Performance

Dehydration can be detrimental to your performance, not only during practice and games but in the classroom/film room as well. Physical and mental performance is impaired when you’re dehydrated as little as 2% of your body weight. When dehydration reaches 5%, there is a 30% decline in performance. Endurance is also greatly impaired when severe dehydration sets in. The greatest danger is to the heart; plasma and blood volume fall, increasing blood thickness while lowering central venous pressure. This, in turn, causes difficulty when the body is trying to return blood to the heart. It is vital not only for exercise, but also for life.

Steps to take when dehydrated

1. Go to a cool or shaded area
2. Seek help from your sports medicine team
3. Drink clear fluids: water, electrolytes, pickle juice, etc.
4. Continue to drink these fluids until and after you are re-hydrated

Grab a water bottle and keep it by your side at all times! If drinking water is difficult for you, add flavors such a lemon, lime, or other fruit you enjoy. Athletes with high sweat rates should also consume fluids that replace electrolytes lost in sweat such as sodium and potassium. Challenge yourself and teammates to see who can meet their fluid needs each day. Drink up!

Beat The Summer Heat By Staying Hydrated

As temperatures begin to rise this summer, I think it's a good time to revisit the importance of maintaining proper hydration before, during and after exercise. Whether you are strength training in a gym or participating in a casual jog, it's important to make sure that you are consuming the right amount of water. This in turn, will help you perform at your highest level and will keep your body in a healthy state as you train. Here are a few tips to keep in mind this summer:

How much water should I be drinking?

- Due to variables such as heat, humidity, body composition and exercise intensity, it is very difficult to determine a universal amount of water that should be consumed by each individual. Since everyone is built differently, a simple way to make sure that you are staying properly hydrated is by checking the color of your urine. Whereas colorless or light yellow urine typically suggests proper hydration, dark yellow or amber-colored urine could be a sign of dehydration.

- According to the American Council on Fitness, the following basic water intake guidelines are suggested for individuals performing moderate-to-high intensity exercise:

• Drink 17 to 20 ounces of water 2 to 3 hours before you start exercising
• Drink 8 ounces of water 20 to 30 minutes before you start exercising or during your warm-up
• Drink 7 to 10 ounces of water every 10 to 20 minutes during exercise
• Drink 8 ounces of water no more than 30 minutes after you exercise

What are some signs of dehydration?

- Dark yellow or amber-colored urine
- Nausea or dizziness
- Vomiting
- Muscle Cramps
- Heart palpitations
- Dry mouth or sticky saliva
- Mental confusion
- Weakness
- Loss of consciousness

Severe dehydration or heat illness can be very serious and sometimes life threatening. If you or a teammate experiences any of the above symptoms, seek medical attention immediately.

10 reasons why drugs, alcohol and/or supplements are still an issue in athletics: Marijuana 101

Following up this week on our May 8th 2012 blog titled "10 reasons why drugs, alcohol and/or supplements are still an issue in athletics," we explore our first reason:

           "In a 2009 study, the use of Marijuana amongst NCAA student-athletes had increased by   

            nearly 2 points over a period of 4 years. 22.6 percent of respondents claimed to have used 

            Marijuana within the last 12 months."

This blog is titled Marijuana 101 and can be found on our myPlaybook blog at: http://myplaybook.drugfreesport.com/uncategorized/marijuana-101/

"Tell me and I'll forget. Show me, and I may not remember. Involve me, and I'll understand."
-Native American Saying-

 

Why does the NCAA recommend against the use of dietary supplements?

Every time a student-athlete or a trainer asks us a question about a dietary supplement, we attach a standard warning, regardless of whether the listed ingredients are banned or not. Often, we are asked the questions, “why do you give this warning,” “what does it mean”, and “why do you suggest that student-athletes not use dietary supplements?” Below, is the standard warning we give, with an explanation of the statements.

“Products labeled as dietary supplements sold over the counter, in print advertisements and through the internet are under-regulated by the U.S. FDA. Whether a product is classified as a dietary supplement, conventional food, or drug is based on its intended use by the manufacturer.  Please be aware that some companies manufacturer dietary supplement and conventional food products*. Dietary supplements are at risk of contamination or may include ingredients that are banned under your drug testing policy.    Studies have found 12-25% of dietary supplements contain unlisted steroids, stimulants, or trace metals.” – Why are dietary supplements at a risk for contamination? Consider these points, (1) Manufacturers do not have to prove the safety and effectiveness of a dietary supplement before it is marketed. (2)Manufacturing facilities are virtually unregulated, they are required to adhere to Current Good manufacturing Practices (CGMPs) , but  unfortunately only an average of 5 inspections take place a month (consider the total number of products sold today…thousands!) (3)  A number of company’s contract manufacture their products and leave the sourcing of ingredients to the contracted company.  So the true identity of the ingredients can be cut or changed without the parent company ever knowing.  This was solidified by the FDA’s Brad Williams participating in an education program at Supplyside West, and he said the number one issue with companies inspected under the supplement GMP program has been failure to adequately test ingredients for identity. 

“We cannot guarantee the safety or purity of any dietary supplement product. Also, the claims made by manufacturers may not be backed up with reliable, scientific research. Student-athletes take any dietary supplement at their own risk.” Without proper testing of the finished product, there is no way to know if the ingredients, and their amounts, listed on labels are correct. You could be getting too much, too little, or none at all of the so-called “active” ingredients. Remember, products do not have to prove their level of safety or effectiveness before they are sold. Often, the “research” a company cites is not reliable, has been done by a party that has interest in the success of the product, or is not scientific in nature. Below are a few tactics used by Supplement Company’s:

·         Misrepresented clinical studies (results out of context, “University tested”, inappropriately referencing research results)

·         False, exaggerated, or purchased endorsements (How much money is the athlete making for saying he takes a product?)

·         Media distortion and false advertising (planted stories online, Company reps posing as local gym guy online in forums, “As seen on Oprah”)

·         Omitting relevant Facts (Product marketed to men but all research done on women)

“The REC does NOT recommend the use of any dietary supplement or manufacturer; please submit all dietary supplement questions to the REC.” While we realize that not all companies are trying to dupe consumers or engaging in dishonest practices, there is no easy way to tell between the “good” and “bad” companies.

“Please be aware that some companies manufacturer dietary supplement and conventional food products.  Products produced in the same manufacturing plant or by the same company could potentially have contamination issues.” Be aware that we have no way to know for sure that a product labeled as a conventional food product but still manufactured by a dietary supplement manufacturer is 100% safe, unfortunately.  If a company is manufacturing meal replacement bars, and shakes, but also manufactures DHEA, you could have a potential problem.

“Remember to report all medications and supplements to your sports medical staff, no matter how insignificant you believe them to be, it could save your life.” Your sports medicine staff needs to know what you are taking, even if it is something as simple as a vitamin. Medications and dietary supplements could pose health risk for some if combined. Those in charge of your health need to know everything you take to give you the best care, especially in case of an emergency.

Again, we realize that there may be benefits to some dietary supplements and that not all manufacturers engage in dubious practices. However, our first commitment is protecting the health and safety of student-athletes. Lastly, we are dedicated to helping protect the integrity of sportsmanship in all sports, and at this time that includes not suggesting dietary supplements.

Sports nutrition part 2: Foods that = success and when to eat them

We understand that time is at a premium for most student-athletes. Lack of time is the number one reason many people give for failing to eat sensibly. Don’t let your on-field shortcomings be a result of a poor diet; time does not need to dictate your diet. Proper planning, educating yourself on performance enhancing foods, and working with a sports nutritionist are all ways to fuel your body and reach your peak athletic goals while meeting your own personal health goals.
If you must eat on the go, eat on the go with a plan! Develop a weekly menu with the “basics,” things are constantly changing so be prepared for change. Include, whole wheat breads, lean meats (vegan alternative), and plenty of produce. Find a cooler that can fit in your bag, and include portable foods and snacks; sliced fruit, low sugar yogurt, string cheeses, and protein bars and nuts make great travel buddies.

Breaking Your Fast
Eating breakfast every morning is key; the level of glycogen in your liver can be substantially lower in the morning, so you need to refuel your body to replace the energy it used while you slept.
• Student-athletes who eat breakfast perform better in the classroom than those who skip. A lot easier to think when your body has energy fuel.
• Eating last night’s left over’s is okay (i.e. pizza, Chinese food with rice or even cheese and crackers)
• Traditional breakfast food choices:
o Instant grits/bowl of cereal
o Fruit or yogurt smoothie
o Egg and cheese sandwich
o Waffles with fruit
o Hard- boiled eggs

Pre-workout
3-4 hours before practice, workout or competition keep these tools in mind:
• Consider choosing foods with lots of carbohydrates, such as
o Rice
o Pasta
o Potatoes
o Yogurt
o Fruit smoothies
o Vegetables
o Muffins
o Crackers
o Bread
• Drink tons of water and sport drinks!

1 hour before a practice, workout or competition keep these tools in mind:
• Have a snack:
o ½ a bagel
o Granola bar
o Large banana
• 12 ounces of sport drink

Breaks/Post-Game/Practice
• Halftime/timeouts
o Drink water and/or your favorite flavor of sport drink.
• Post-workout
o Drink approximately 24 ounces of sport drink or water for every pound of body weight that is lost during competition/practice.
o Monitor you urine color. Apple juice color = dehydration and you need more fluids. Lemonade color = hydrated.
o Eat something within 30 minutes of competition/practice.

What about fast food?
• Pizza with thick crust, vegetables, and Canadian bacon, instead of “meat lover’s”
• Single burgers, instead of “double” or “Monster” with bacon and cheese
• Grilled chicken sandwiches or grilled chicken salads instead of fried chicken
• Stir-fried veggies and steamed white rice, instead of meals with large portions of meat or fried egg rolls.
• Grilled meats verses fried meats
• Waffles, pancakes, grits, scrambled eggs, or grilled ham, instead of bacon, sausage or biscuits.
• Avoid these sandwiches: tuna salad, chicken salad or salami. Try turkey, chicken or roast beef and load up on the veggies.
• Avoid the pasta dishes with large amounts of meat, cheese and cream. Opt for lots of pasta and red sauce.
Remember: Aim to be consistent in your eating habits, go for quality foods and remember timing of meals will impact your performance. Know your schedule and plan ahead by bringing or purchasing appropriate foods and beverages. Try to eat regular meals and snacks throughout the day to maintain energy levels but don’t have a large meal right before an event. Good eating habits are important at all times (before the game, after the game, and during the off-season)

Sports nutrition part 1: Does your food = success?

Superior athletic ability comes from genetics and training. However, witout good food choices and the correct timing of meals, your training and performance will suffer. You need a fueling plan that includes the right balance of carbohydrates, protein, and fat, enough vitamins and minerals, and the correct amount of fluids.

Nutrition is one of the corner stone’s of athletic success, combined with training, skill set and rest. You cannot train harder to make-up for a poor diet, or sleep, less and expect to compete at an elite level. Eating for performance equals eating on a schedule; this does not mean you have to clock in for meals, but it does mean that you should get a better understanding of what, how much, and when you eat for optimal performance.

Eating for Performance Goals:

1. Keep a high energy level throughout workouts

2. Repair and strengthen muscles

3. Avoid illness, infection, or any outside force that could suppress immune
system during training

4. Recover from training and prepare for practice, or event

Athletes must fuel the body with calories and nutrients from “healthy” foods. Sports scientists generally recommend a high-performance diet – in moderation – consisting of carbohydrates, proteins and fats. Carbohydrates and fats provide the raw material that creates ATP (adenosine triphosphate) that is the true energy source inside the cell. Your daily food intake must contain adequate amounts of calories and nutrients to meet this demand.

• Carbohydrates – Play a vital role in many functions of the body, but one of the main functions is to provide energy for the contracting muscle. The storage form of carbohydrates is called Glycogen; found mainly in muscle and the liver. Muscle glycogen is a readily available energy source for the working muscle. Athletes require Carbohydrates in all phases of working out and competition. The brain is highly dependent on glucose as a fuel, so remember carbohydrates are not the enemy.

• Fats – Contrary to belief fat is a contributor to health and performance for athletes. You need fat for energy,and to move substances in and out of cells, and it helps keep your brain and nervous system healthy. Lastly, fat helps your body to use some vitamins as well as plant chemicals known as "phytochemicals."

• Protein – Major functions include build, repair and maintain your body’s muscle tissue and provide energy, if necessary. Protein is also responsible for healthy blood cells, Key enzymes and strengthening the immune system. Protein cannot build muscle alone, it requires carbohydrate calories to provide the body with energy.

•Vitamins and Minerals - do not give you more energy, but they help to unlock the energy stored in food so your body can use it as fuel.

•Fluid - Water is the most important nutrient; be sure to replace the fluids you lose through sweat when you are active.


Aim to be consistent in your eating habits, go for quality foods and remember timing of meals will impact your performance. Know your schedule and plan ahead by bringing or purchasing appropriate foods and beverages. Try to eat regular meals and snacks throughout the day to maintain energy levels but don’t have a large meal right before an event. Good eating habits are important at all times (before the game, after the game, and during the off-season)

Part 2 will focus on foods that = success and when to eat them, stay tuned!
