                                             Sport Supplements for Teens

If you're a competitive athlete or a fitness buff, improving your sports performance is probably on your mind. Lots of people
wonder if taking sports supplements could offer fast, effective results without so much hard work. But do sports supplements
really work? And are they safe?

What Are Sports Supplements?

Sports supplements (also called ergogenic aids) are products used to enhance athletic performance that may include vitamins,
minerals, amino acids, herbs, or botanicals (plants) — or any concentration, extract, or combination of these. These products are
generally available over the counter without a prescription.

Sports supplement are considered a dietary supplement. Dietary supplements do not require U.S. Food and Drug Administration
(FDA) approval before they come on the market. Supplement manufacturers do have to follow the FDA's current good
manufacturing practices to ensure quality and safety of their product, though. And the FDA is responsible for taking action if a
product is found to be unsafe after it has gone on the market.

Critics of the supplement industry point out cases where manufacturers haven't done a good job of following standards. They also
mention instances where the FDA hasn't enforced regulations. Both of these can mean that supplements contain variable amounts
of ingredients or even ingredients not listed on the label.

Some over-the-counter medicines and prescription medications, including anabolic steroids, are used to enhance performance but
they are not considered supplements. Although medications are FDA approved, using medicines — even over-the-counter ones
— in ways other than their intended purpose puts the user at risk of serious side effects. For example, teen athletes who use
medications like human growth hormone (hGH) that haven't been prescribed for them may have problems with development and
hormone levels.

Lots of sports organizations have developed policies on sports supplements. The National Football League (NFL), the National
Collegiate Athletic Association (NCAA), and the International Olympic Committee (IOC) have banned the use of steroids,
ephedra, and androstenedione by their athletes, and competitors who use them face fines, ineligibility, and suspension from their
sports.

The National Federation of State High School Associations (NFHS) strongly recommends that student athletes consult with their
doctor before taking any supplement.

Common Supplements and How They Affect the Body

Whether you hear about sports supplements from your teammates in the locker room or the sales clerk at your local vitamin store,
chances are you're not getting the whole story about how supplements work, if they are really effective, and the risks you take by
using them.

Androstenedione and DHEA

Androstenedione (also known as andro) and dehydroepiandrosterone (also known as DHEA) are prohormones or "natural
steroids" that can be broken down into testosterone. When researchers studied these prohormones in adult athletes, DHEA and
andro did not increase muscle size, improve strength or enhance performance.

The side effects of these "natural" steroid supplements like DHEA and andro aren't well known. But experts believe that, when
taken in large doses, they cause effects similar to stronger anabolic steroids.

What is known is that andro and DHEA can cause hormone imbalances in people who use them. Both may have the same effects
as taking anabolic steroids and may lead to dangerous side effects like testicular cancer, infertility, stroke, and an increased risk

of heart disease. As with anabolic steroids, teens who use andro while they are still growing may not reach their full adult height.
Natural steroid supplements can also cause breast development and shrinking of testicles in guys.

Creatine

Creatine is already manufactured by the body in the liver, kidneys, and pancreas. It also occurs naturally in foods such as meat
and fish. Creatine supplements are available over the counter, and teens make up a large portion of the supplement's users.

People who take creatine usually take it to improve strength, but the long-term and short-term effects of creatine use haven't been
studied in teens and kids. Research in adults found that creatine is most effective for athletes doing intermittent high-intensity
exercise with short recovery intervals, such as sprinting and power lifting. However, researchers found no effect on athletic
performance in nearly a third of athletes studied. Creatine has not been found to increase endurance or improve aerobic
performance.

The most common side effects of creatine supplements include weight gain, diarrhea, abdominal pain, and muscle cramps.
People with kidney problems should not use creatine because it may affect kidney function. The American College of Sports
Medicine recommends that people younger than 18 years old do not use creatine. If you are considering using creatine, talk with
your doctor about the risks and benefits, as well as appropriate dosing.

Fat burners

Fat burners (sometimes known as thermogenics) were often made with an herb called ephedra, also known as ephedrine or ma
huang, which acts as a stimulant and increases metabolism. Some athletes use fat burners to lose weight or to increase energy —
but ephedra-based products can be one of the most dangerous supplements. Evidence has shown that it can cause heart problems,
stroke, and occasionally even death.

Because athletes and others have died using this supplement, ephedra has been taken off the market. Since the ban, "ephedra-
free" products have emerged, but they often contain ingredients with ephedra-like properties, including bitter orange or country
mallow. Similar to ephedra, these supplements can cause high blood pressure, heart attack, stroke, and seizures.

Many of these products also contain caffeine, along with other caffeine sources (such as yerba mate and guarana). This
combination may lead to restlessness; anxiety, racing heart, irregular heartbeat, and increases the chance of having a life-
threatening side effect.

Will Supplements Make Me a Better Athlete?

Sports supplements haven't been tested on teens and kids. But studies on adults show that the claims of many supplements are
weak at best. Most won't make you any stronger, and none will make you any faster or more skillful.

Many factors go into your abilities as an athlete — including your diet, how much sleep you get, genetics and heredity, and your
training program. But the fact is that using sports supplements may put you at risk for serious health conditions. So instead of
turning to supplements to improve your performance, concentrate on nutrition and follow a weight-training and aerobic-
conditioning program.

Tips for Dealing With Athletic Pressure and Competition

Advertisements for sports supplements often use persuasive before and after pictures that make it look easy to get a muscular,
toned body. But the goal of supplement advertisers is to make money by selling more supplements, and many claims may be
misleading. Teens and kids may seem like an easy sell on supplements because they may feel dissatisfied or uncomfortable with
their still-developing bodies, and many supplement companies try to convince teens that supplements are an easy solution.

Don't waste your money on expensive and dangerous supplements. Instead, try these tips for getting better game:

•Make downtime a priority. Studies show that teens need more than 8 hours of sleep a night, and sleep is important for athletes.
Organize time for sleep into your schedule by doing as much homework as possible on the weekend or consider cutting back on
after-school job hours during your sports season.

•Try to relax. Your school, work, and sports schedules may have you sprinting from one activity to the next, but taking a few
minutes to relax can be helpful. Meditating or visualizing your success during the next game may improve your performance;
sitting quietly and focusing on your breathing can give you a brief break and prepare you for your next activity.

•Choose good eats. Fried, fatty, or sugary foods will interfere with your performance. Instead, focus on eating foods such as lean
meats, whole grains, vegetables, fruits, and low-fat dairy products. Celebrating with the team at the local pizza place after a big
game is fine once in a while. But for most meals and snacks, choose healthy foods to keep your weight in a healthy range and
your performance at its best.

•Eat often. Sometimes people skip breakfast or have an early lunch, then try to play a late afternoon game. Not getting enough
food to fuel an activity can quickly wear you out — and even place you at risk for injury or muscle fatigue. Be sure to eat lunch
on practice and game days. If you feel hungry before the game, pack easy-to-carry, healthy snacks in your bag, such as fruit, trail
mix, or string cheese. It's important to eat well after a workout.

•Avoid harmful substances. Smoking will diminish your lung capacity and your ability to breathe, alcohol can make you sluggish
and tired, and can impair your hand-eye coordination and reduce your alertness. And you can kiss your team good-bye if you get
caught using drugs or alcohol — many schools have a no-tolerance policy for harmful substances.

•Train harder and smarter. If you get out of breath easily during your basketball game and you want to increase your endurance,
work on improving your cardiovascular conditioning. If you think more leg strength will help you excel on the soccer field,
consider weight training to increase your muscle strength. Before changing your program, though, get advice from your doctor.

•Consult a professional. If you're concerned about your weight or whether your diet is helping your performance, talk to your
doctor or a registered dietitian who can evaluate your nutrition and steer you in the right direction. Coaches can help too. And if
you're still convinced that supplements will help you, talk to your doctor or a sports medicine specialist. The doc will be able to
offer alternatives to supplements based on your body and sport.
