Nutrition for Young Runners

Running is a popular sport with children and adolescents around the world.

Depending on the age and calibre of the young athlete, training may range from the weekly school Physical Education lesson to structured sessions at a local club or to participation in one of the special training plans on The World Keeps Running.

The goals of training may range from simply having fun, to improving fitness and physique, to developing running skills and preparing for an event.

For the youngest age groups, there should be no special need for any change to diet. The main aims are to minimise the risk of gastrointestinal upset and to avoid problems of dehydration on hot days. It may be best to avoid solid food for two to three hours before training and particularly an event as the combination of exercise and nerves can cause some gastric distress.

Children can often be out in the sun for many hours on sports days, and adults should be vigilant to ensure frequent application of sun cream and to be aware of any child who seems to be having problems. Ample fluid should be available, and children may need to be reminded to take small amounts of drinks at regular intervals.

The physiology of children and adolescents differs from that of adults in several ways. The mechanisms of thermoregulation are less efficient in children, and special attention must be paid to the environment, activity patterns, clothing and hydration to avoid problems of hyperthermia or hypothermia.

The growth spurts during childhood and adolescence require nutritional support in terms of adequate intake of energy, protein and minerals.

Active young people may find it difficult to meet their needs for energy and nutrients when the costs of training and growth are added. Young people may not have developed the nutritional knowledge and time management skills to fit in all the eating occasions required to achieve high energy, nutrient-rich eating.

The rate of obesity in children is still rising, but active youngsters do need a plentiful supply of energy from foods and energy-containing drinks.

Young athletes eating a wide range of foods should not need to use dietary supplements, and athletes and coaches should be aware that these do not provide a short cut to success.

Encourage children to become involved in menu planning for the family meals, and for special needs associated with their training and competition sessions. Encourage positive messages that good eating practices, involving good choices of foods and drinks, are part of the formula for sporting success, and a healthy life.

Children often need snacks to meet their energy needs over the day, and the special needs of recovery from sport. These snacks should involve nutrient-rich choices such as fruit, sandwiches, dried fruit and nuts, flavoured dairy products, and cereals and milk. Some planning is needed to have these choices on hand over the day, and before or after sport.

How Much Water Does An Athlete Need?

 

By Dr. Lorraine Williams, chiropractor turned TrackMom.

One of the biggest challenges for parents, athletes and their coaches is determining how much water an athlete needs at different times in their day and training.

If the athlete’s urine is dark and scanty, it is concentrated with metabolic wastes and the athlete needs to drink more fluids. When the urine is pale yellow, your body has returned to its normal water balance. Your urine may be dark if you are taking vitamin supplements; in that case, volume is a better indicator than color.

All athletes must drink water before, during, and after exercise. Follow the basic guidelines below to be sure that a child is drinking enough water throughout an exercise session.

• Before Exercise: Drink 10 to 14 oz. of cold water 1 to 2 hours before the activity. Drink 3-6 oz.of cold water or diluted fruit juice 15 to 20 minutes before the activity.
• During Exercise: Drink 3 to 4 oz. of cold water every 15 minutes.
• After Exercise: Drink 2 cups (16 oz.) of cold water for every pound of weight loss. With no weight loss still drink the minimum of 8oz of water.

You must watch and see how much water a young athlete actually drinks. Supervision is essential because children do not instinctively drink enough fluid to replace body water losses. Children may not recognize the symptoms of heat strain, and they may push themselves to the point of heat injury. Young athletes can use non HFCS sports drinks, especially during activities lasting lore than 90 minutes (such as Football or  Soccer). These drinks should contain between 6 and 8 percent carbohydrate or 15 to 18 grams of carbohydrate per cup.

Other tips include:

• If products labeled “sports drinks” do not meet these guidelines, they may need to be diluted. Water is adequate for most children.  However, some youth athletes are more likely to drink sufficient amounts if you give them flavored fluid; sports drinks or diluted fruit juice are appropriate choices.
• Be sure to dilute fruit juice at least twofold: 1 cup of water for every 1 cup of juice.  Tell children not to drink carbonated sodas or undiluted fruit juice as a fluid source during exercise. These beverages are too rich in carbohydrate (which can cause stomach cramps, nausea, and diarrhea).
• Caffeinated beverages (such as tea, coffee, and cola beverages) will dehydrate the body even more.
• Athletes can also replace their body fluids with foods containing a lot of water, such as oranges, watermelon, apples, grapes, and tomatoes, along with water. These foods provide water and carbohydrate, and they are good for replacing lost water and lost energy (glycogen) after exercise.
