This pattern, termed "co-contraction," requires extra metabolic energy, which makes children metabolically less economical than adolescents and adults (Frost et al., 1997). Most teen athletes should drink about 8 ounces of fluid every 20 minutes during an intense workout. Carbohydrate supplementation improves stroke performance in tennis. Carbohydrate drinks delay fatigue during intermittent, high-intensity cycling in active men and women. 48: 104-108. SSE #77 VOLUME 13 (2000), NUMBER 2, Oded Bar-Or, M.D. One should realize, though, that protein intake sufficient to meet the Recommended Dietary Allowance (RDA) may not guarantee an adequate nutritional status. Sawka, M.N., and K.B. J. Appl. The main strategy is to enhance thirst and to educate athletes (but also the coach, parents and team physician) to drink frequently, even when they are not thirsty.

Optimal Nutrition for Youth Athletes: Food Sources and Fuel Timing Jennifer Sacheck, Ph.D. and Nicole Schultz, M.S., MPH Summary Proper nutrition for youth athletes is not only important for maintaining health and optimizing sports performance, but also is critical for meeting growth and development requirements. ScienceDirect ® is a registered trademark of Elsevier B.V. ScienceDirect ® is a registered trademark of Elsevier B.V. Nutritional Requirements of the Child and Teenage Athlete. Single tests of muscle strength, power, and local muscle endurance are typically not dramatically affected by dehydration (Horswill, 1992). The energy cost of walking or running at any given speed, when calculated per kg body mass, is considerably higher in children than in adolescents and adults, and the younger the child, the higher the relative cost (Åstrand, 1952; Daniels et al., 1978; MacDougall et al., 1983). J. Appl. Sci. Sports Exerc. Most of the research on sports nutrition has been done with adults. Carmel, IN: Cooper Publishing Group, Whether children's preferential use of fat as an energy substrate has any implications for nutritional recommendations has yet to be determined. J. Electromyog. Sci. Therefore, adult-based tables of estimated energy expenditure in any given sport might underestimate the actual needs of children. Fluids are very important for maintaining hydration and should be consumed before, during and after athletic events to prevent dehydration. Med. Roemmich (1990). Active children have specific requirements. Brown and C.F. Inappropriate fluid replenishment patterns may also result in electrolyte insufficiency. For example, a study of adolescent wrestlers showed that their protein status became less than optimal as the season progressed, even though their reported protein intakes seemed sufficient (Horswill et al., 1990). Pandolf (1990). Sports 10: 200-203. * To facilitate growth and development, the daily protein requirements per unit body weight are higher for children than for adults, but it is unclear whether child athletes need more protein than their inactive counterparts for normal growth and development and for optimal performance. In: C.V. Gisolfi and D.R. Perspectives in Exercise Science and Sports Medicine, Vol. Perspectives in Exercise Science and Sports Medicine, Vol. J. Åstrand, P-O. Therefore, beverages flavored to satisfy each athlete's taste preference should be readily available for the athlete to drink before, during, and after training sessions and competitions. Consistency of preventing voluntary dehydration in boys who drink a flavored carbohydrate-NaCl beverage during exercise in the heat. Such relative deficiency may have been secondary to "making weight" through restriction in energy intake. While young athletes rely on their parents and health professionals for advice, they are extremely susceptible to peer and media influence and the plethora of misinformation that exists in the sports nutrition world.8 As a result, obstacles to improving the nutritional status and consequent performance of the young athlete abound. Wilk, B., and O. Bar-Or (1996). In addition, the requirements may further increase with increasing exercise training. Recommended Dietary Allowances, 10th ed. Pediatr. Malina (ed.) Competitive Sports for Children and Youth. Leatt, P.B., and I. Jacobs (1989). 31: S322. The latter observation is important because trained athletes, particularly if acclimatized to the heat, produce much more sweat than do non-athletes, so their fluid requirements are considerably higher. Such insufficient drinking may result in "voluntary dehydration," i.e., dehydration that occurs even when beverages are offered in abundance. Schemmel, R.A., E. Ryder, J.A. University of Glasgow, Glasgow, Scotland. Oxygen uptake during running as related to body mass in circumpubertal boys: a longitudinal study. Davis, J.M., D.A. Effect of body water loss on physiological function and exercise performance. Factors 14: 155-160. If children are eating a good Canada. In: D.R. J. Appl. Nelson (1998). J. Champaign, IL: Human Kinetics, Protein Ten percent to 30 percent of the calories in a teen's diet should come from protein, providing a minimum of 34 grams of protein daily for teens between 9 and 13 years of age. 4: 194-198. 2, Youth, Exercise, and Sport. Although athletes who are involved in strength and endurance training may need slightly more protein, it’s a mistake to think you can simply build up muscles by eating lots of protein. The added intake when carbohydrate and NaCl were included was enough to prevent dehydration altogether (Wilk & Bar-Or, 1996). Int. * Special attention must be paid to prevent voluntary dehydration in children who exercise in hot/humid climates. Hamilton, Ontario Khoo, P.M. Kris-Etherton, S.S. Jonnalagadda, B. Sherr, and J.A. Physiol. Children will voluntarily drink more when the drink is tasty. Ephedrine-type … According to the Food and Nutrition Board of the Institute of Medicine, male high school athletes need between 3,000 and 6,000 calories a day, and … Aging is linked to nutrient deficiencies, so it's especially important to eat healthy as you get older. Children's thirst can be enhanced during exercise by flavoring the drink and by adding sodium chloride (NaCl) and carbohydrate in amounts typically found in sports drinks, e.g., 18 mmol NaCl/L (110 mg/8 oz) and 6% sugar (14 g/8 oz) (Rivera-Brown et al., 1999; Wilk & Bar-Or, 1996). Children, however, need different amounts of specific nutrients at different ages. * Cooling a drink to refrigerator temperature and, in particular, adding flavor to the drink will increase its palatability. 7: 179-186. A physiological and nutritional profile of young female figure skaters. Although there are no similar studies with children, it is reasonable to assume that they will derive the same benefit when the drink is chilled. Carmel, IN: Cooper Publishing Group, pp.1-30. Med. Unlike adults, nutrition for youngsters must provide for physical growth and development. In a longitudinal study Daniels et al. Pediatric Sports Medicine for the Practitioner. (abstract). Sports Med. Calcium requirements for adolescent athletes are no different from that of non-active adolescents; however, requirements are greater than that of adults due to growth. Plasma metabolites, volume and electrolytes following 30-s high-intensity exercise in boys and men. Sports Exerc. Welsh, R.S., S. Byam, W. Bartoli, J.M. pp. 86: 78-84. Carbohydrate foods provide not only the body's preferred energy source, but also vitamins, minerals, and fiber necessary during the growth and development stage of adolescence. Iron deficiency can be a problem for athletes, particularly for girls who have begun to menstruate. Copyright © 2020 Elsevier B.V. or its licensors or contributors. Eur. * Compared with adults, children and adolescents use more fat and less carbohydrate during prolonged exercise. Deliberate fluid loss to "make weight" in sports such as wrestling or rowing may have negative psychological effects such as aggressiveness, anger and anxiety (Steen & Brownell, 1990). J. Maximal aerobic capacity of Canadian school children: prediction based on age-related oxygen cost of running. Heigenhauser, and O. Bar-Or (1996). Unfortunately, the lack of a proper control group in the study prevents the determination of whether the above decrease in cost represented a training effect or an aging effect. For more information on these issues see reviews by Nelson-Steen (1996) and by Loosli and Benson (1990) and articles regarding young gymnasts (Benardot et al., 1989; Ersoy, 1991), runners (Schemmel et al., 1988), figure skaters (Delistraty et al., 1992; Ziegler et al., 1998) and wrestlers (Schemmel et al., 1988). The addition of salt tablets to a drink should be discouraged, because such tablets contain excessive amounts of salt, which may cause irritation to the stomach lining. Med. Roemmich, J.N., W.E. Sci. Am. Consuming less than 20 g of carbohydrates a day would remove foods such as milk, yogurt, fruit, grains, and starchy vegetables. Drinking was enhanced by a further 46% when the subjects drank a grape-flavored sports drink (Gatorade) that contained carbohydrate and NaCl. Gatorade Sports Science Institute® 14: 114-143. Hay, J.D. Here are some general guidelines: 1. Europ. Wilson (1992). Fluid and electrolyte loss during exercise: the pediatric angle. Lemon, P.W.R, M.A. Most important, excessive dehydration may lead to, and aggravate, heat-related illness. Brownell (1990). But if your child or teen is an athlete performing at a high level on a regular basis, you may have additional concerns about their nutrition and dietary needs. Washington, D.C.: National Academy Press. Still, there is reason to assume that energy requirements of child athletes are different from those of adults. Perspectives in Exercise Science and Sports Medicine, Vol. Coaches, parents, team physicians, and athletic trainers should be sensitive to protein requirements of young athletes; age-related differences in energy expenditure during exercise; differences between children and adults in the utilization of fat and carbohydrates during prolonged exercise; and means of enhancing the amount of fluid intake during exercise to prevent exercise-induced dehydration, particularly in hot/humid climates. The effects of dehydration have been studied mostly in adults, but it is clear that loss of body fluids is usually deleterious to performance and health.
