Tennis Nutrition: Planning Your Ideal Diet

This is a guest post from avid tennis player and blogger, Maria Rainer.

If you’re going to invest in maintaining the best possible conditions for your primary tennis equipment, your own body should top the list. Sure, it’s important to re-string your racket and make sure your shoes don’t slip, but taking care of your body is even more important. Even beyond wearing braces for vulnerable joints, your diet and nutrition should be a focal point of your tennis fitness routine.

Because it’s so easy to slip when you’re on a specific diet, planning ahead can help you ensure that you’ll have the best possible opportunities to maintain healthy tennis nutrition. To start planning your success, check out the following categories of nutrition you’ll need to address.

General Nutrition
To maximize the benefits you receive from everyday meals, avoid more than three servings of alcohol each week and stay away from excess calories and saturated fats. Make sure that you aren’t experiencing any mineral or caloric deficiencies by taking vitamins designed for your gender, age group, and level of activity.

Use an online calorie intake calculator to determine how many calories you should consume in a given day, then make sure that you don’t come up short of this number or exceed it by too much. You can do this by using a caloric value calculator if you don’t have access to nutrition labels on everything you consume.

You daily caloric intake should be accounted for by the following:

• 3 ounces of whole grain
• 2 ½ to 3 cups of vegetables
• 1 ½ to 2 cups of fruits
• 3 cups of milk products
• 5 to 6 ½ ounces of meat or other proteins
• 2 to 3 liters of water

Pre-Match Nutrition
Many tennis players and nutritionists who understand the demands of extended, high-intensity physical activity advocate carbo-loading before a match. This means that it’s advisable to consume enough carbohydrates to get you through the match without sapping permanent energy stores like muscle.

To do this, avoid “empty” or simple carbs like sugar and white bread and focus on complex carbs instead. Start adding more complex carbs to your diet the evening before your match, at the very latest. Anything that contains barley, buckwheat, bran, cornmeal, oatmeal, wheat germ, brown rice, or similar whole grains will help you store energy for the upcoming match.

Add extra water, juice, and sports drinks to your diet as you begin to consume more complex carbs and consider adding salt to compensate for sodium loss through sweat. This will help you to stay hydrated during the match.

During-Match Nutrition
Keep drinking and make sure that you’ve packed some isotonic sports drinks (containing six to eight percent carbohydrates). Drinks that contain sodium, glucose, and electrolytes are also helpful. Avoid drinking too much straight water, or you might risk causing mineral deficiency.

Post-Match Nutrition
Try to consume a high-carb meal within two hours of finishing your match. If you can do this immediately, you’ll be able to replenish your energy stores much faster than you will if you wait too long. In addition to restoring carbs, you’ll want to keep consuming fluids and electrolytes to make sure that your body won’t be deficient in these important diet components.

To adhere to your new diet, make sure that you plan when you’ll go shopping for groceries, which types of meals you’ll make and when you’ll prepare them, and which restaurants you’ll go to for healthy food that fits your diet. Set yourself up for success by focusing on tennis nutrition and maintaining it with deliberate planning.

Are You Taking Drugs That Cause Dehydration?

The heat wave just continues and its extremely important to stay hydrated when you're out on the tennis courts. But, be aware - it's not just the heat that can cause you to become dehydrated. Certain common drugs can also lead to dehydration because they cause you to urinate or perspire more than usual. These include diuretics (obviously), antihistamines, blood pressure drugs and a few psychiatric medications. If you're taking any of these, talk to your doctor to get all of the details and then up your water intake and avoid playing during the hottest times of the day.

The Benefits of Caffeine

I know it's the middle of a sweltering summer and the last thing you're thinking when you're sweating it out on the court is, "If only I could get my hands on a steamy cup of coffee!" But don't give up on your caffeine just because of the heat. According to a recent issue of Prevention magazine, there are all kinds of great reasons to drink coffee:
  • It can help prevent DNA damage that leads to skin cancer.
  • It is full of healthy antioxidants.
  • And, people who drink 3 to 4 cups a day have a 25% lower risk of developing Type 2 diabetes.
Wow! Just remember - caffeine is a diuretic (see this post - Quick Tennis Fix: Cut Your Caffeine - for more info on that) so you don't want to be drinking coffee or any other caffeinated beverage during your match. Instead, enjoy your coffee during a non-tennis-playing moment and load up on water and other forms of hydration during matches (see Drink! Drink! Drink! to find out what you should be drinking).

Avoid Muscle Cramps in Tennis

While summer is not officially here, the sweltering heat is. And, during a night match I played recently, I saw one of the dangers that comes with playing tennis in all of this heat - muscle cramps. A woman on the court next to me was playing for maybe 10 to 15 minutes when she suddenly sat down hard on the court with a cramp in her calf. She was unable to massage it out, although she really tried. She ultimately hobbled off the court, her tennis match at an end.

So what causes muscles cramps like that, how do you treat them, and how can you prevent cramping in the first place?

CAUSES: In sports like tennis, muscle cramping typically occurs in the big muscles of the legs - the calf and the hamstring. There are two main causes for these cramps: muscle fatigue and dehydration. Factors that can make you more likely to experience cramping include older age (again with the old age stuff!), poor or nonexistent stretching habits, lack of conditioning, dehydration, high rate of sweating, or excessive exercise intensity and duration.

TREATMENT: So what do you do if you're mid-match and you suddenly experience painful cramps? How do you treat them? First, of course, you have to stop playing, stretch and massage the cramped muscle and ice the area. You will probably be unable to continue playing without further cramping (sorry - this may mean a forfeit). If you think your cramping is due to dehydration and excessive sweating, drink some water or, more helpful, a sports drink to help replace sodium and electrolytes. You'll need some time to recover from muscle cramps so this may mean taking a few days off from tennis and other exercise.

PREVENTION: Of course, it would be best if you never got muscle cramps in the first place. To prevent them, be sure and stretch your muscles before starting a match. Need some good on-court stretches? Check out this post: Winning The Warm-Up. Also, as we've always advocated here at Tennis Fixation, get yourself hydrated. And stay hydrated throughout your match and after to avoid cramping. See these posts for more info on the importance of hydration: Drink! Drink! Drink!, Eat Your Water and Quick Tennis Fix: Hydrate! Finally, keep loose by doing those stretches on a regular basis (yes, even if you're not about to jump on the court) and consider getting a massage every once in a while. At last, you have a great excuse to justify that massage you've been wanting!

Is Your Thirst Unquenchable?

I know I spend a lot of time here at Tennis Fixation trying to keep you hydrated (see, for example, Drink! Drink! Drink!). But do you find yourself constantly drinking and never feeling satisfied? Is your thirst unquenchable? If so, pay attention! That insatiable thirst may be a clue that you have diabetes. Visit your doctor right away and get tested for diabetes!

Cold Weather Tennis

Last week I played tennis where temperatures started out in the (get ready for this) 40's! Here in Houston that is FREEEEEZZZZING!  OK, I know. That's not really very cold at all.  In fact, on both mornings, it went from being a little chilly at the beginning of each match to being pretty darn warm by the end. But I live in Texas because I like hot weather and the thought of wearing tights under a tennis skirt - Yuck!  Not the tennis fashion statement I'm looking to make.

But, the reality is, its time to think about cold weather tennis.  If you're a true die-hard tennis player, you want to play even when it gets pretty darn chilly.  So the issue becomes what to wear and how to play on these frosty days (or nights).  Here are some tips that might make your next cold weather match more enjoyable:
  • Wear layers. Lots and lots of layers. If I think I'm going to be playing in the cold, I wear a whole lot of layers.  On top:  racer-back tank, long-sleeved sports t-shirt made of some type of dry-wick fabric, sweat shirt or long-sleeved cotton t-shirt, hoodie, sleeveless ski vest.  On bottom:  tights under skirt with built-in shorts (meaning those tights are staying on) or long yoga pants that will securely hold the ball in the back at the waist (see below).  On my head:  a baseball-type hat.  I don't ever wear a visor because it makes my hair look weird.  I don't wear a ski hat for the same reason (unless I'm skiing and then I don't really care because everyone's hair looks weird then).  So with all of these layers on, you can see its easy to start peeling the clothes off as I get warmer and, in fact, I would rather be a little bit chilly than play with all of this bulk so I never actually play a match with this much stuff on.
  • Make sure what you wear on the bottom allows you to hold onto a tennis ball.  Deciding what to wear on the bottom is the big cold-weather issue for me because it has to be something that allows me to hold onto a second ball without any possibility of it falling out since I know from previous posts that I can't call a let for something I cause myself like a ball falling out of my pants and rolling around on the court (click on these posts for more info:  Tennis Lets-Get It Right! and Update on the Loose Balls Issue).  And I don't like those little ball holder thingys that some people wear.  If you're OK wearing one of those thingys, this won't be as big of an issue for you.  So if I wear tights, I have to have a skirt with shorts on top so I can tuck a ball into the shorts.  And if I wear pants, they have to be yoga pants that fit well enough that I can tuck a ball into the waistband in back without any possibility of it falling out or down into my pants.  Nice visual there.
  • Wear gloves.  I have cotton running gloves in my bag that i like and at least get me started during warm-up.  They provide a little more traction and "feel" than some of the cheap double-knit gloves.  A lot of people use Isotoner style driving gloves.  I just never remember to buy those so I stick with my running gloves.  I usually take them off by the time the match actually starts as I know I'll play better if my hands are a little cold but I can actually feel my racquet.
  • Wear sunscreen.  Even though its cold, it can still be pretty sunny and that means sunscreen is a must.  And, if you start taking off layers on top, be sure you protect your shoulders and any other exposed skin from the sun.  This is why spray-on sunscreen is great - its quick and easy to apply and can be done during a changeover.
  • Wear lip balm.  Cold weather usually means dry weather and often means wind.  I never notice having chapped lips when its hot outside.  But when its cold - sandpaper!  So avoid chapped lips by keeping a good lip balm (hopefully with sunscreen) in your bag.
  • Keep hydrated.  When the weather's hot, its easy to remember to drink and keep hydrated.  When its cold, its not so easy.  But you can get dehydrated and suffer the effects of that just as easily in the cold.  So keep drinking during your match.  
  • Be prepared for the cold weather game.  You'll find that, when its cold outside, the tennis balls are just not as bouncy.  So be ready to hit harder and deeper than you're used to and come into the net a lot (which you should be doing in doubles anyway).  This will help compensate for the ball being a little "dead" feeling.

Quick Tennis Fix: Cut Your Caffeine!

Do you start the morning with coffee and then transition to your favorite caffeinated soda? Are you doing this even though its blistering hot outside by the time your tennis match starts? Bad idea! Caffeine is a diuretic and not only will not hydrate you, it will actually increase the likelihood of you becoming dehydrated. Acceptable things to drink during a match are water, fitness and flavored waters, and sports beverages. Fruit juices and decaffeinated sodas are a distant second and caffeinated beverages do not even count towards fluid intake. The way I look at it is - I have enough issues when I'm playing tennis. I don't need to add to my problems by dehydrating myself and drinking caffeine!

Quick Tennis Fix: Hydrate!

Warm weather is definitely here and as matches drag on, the temperatures go up and up. To keep yourself going in those three-setters, or long two-setters, drink plenty of water - before, during and after your match. And remember that the time to drink is not when you feel thirsty. By then, its too late. You're on your way to dehydration. Hydrate yourself well in advance of your match to keep playing! For more tips on drinking and hydration, click here to check out my "Drink! Drink! Drink!" post.

Drink! Drink! Drink!

No, I'm not talking about the latest wild party I've been to (which would be a very short, possibly non-existent post). Rather, the weather has warmed up really quickly and its time to hydrate.

You know how important it is to keep on drinking while you're playing tennis. What's the best way to get yourself hydrated on the courts?

1. Start drinking before you start playing. Don't wait to drink until you're already sweating it out on the courts.
2. Drink water. It's the best thing to keep you properly hydrated.
3. Try fruit-flavored, calorie-free waters. There are plenty of substitutes for water out there so give them a try and find the one you like.
4. Keep a water bottle or jug with you all the time, even when you're not playing.
5. Drink until your urine is pale yellow. Maybe you don't want to look at your urine. Or maybe you don't want to admit that you look at your urine. But this is a great way to tell whether or not your dehydrated. Pale yellow = good. Dark yellow = really bad.
6. After you finish, recover by drinking water or a sports drink to replenish your losses.
