nutritional requirements of the child and teenage athlete

Consistency of preventing voluntary dehydration in boys who drink a flavored carbohydrate-NaCl beverage during exercise in the heat. Timing of food consumption is important to optimize performance. Calcium and vitamin D are important nutrients for good bone health. Sports Med. There is little information as to whether or not young athletes consume enough proteins. Champaign, IL: Human Kinetics, In addition, the requirements may further increase with increasing exercise training. Proper nutrition in combination with the appropriate amount of physical activity is of paramount importance for this era of adolescents. Pediatric Sports Medicine for the Practitioner. Resp. (1952). Nutrition plays a major role in both optimal growth and development, as well... Total energy intake. Diet. In conclusion, the effect of training on the energy cost of activity is not yet clear, nor is it known whether the above considerations have direct implications for nutrition. Heigenhauser, and O. Bar-Or (1996). Assoc. One implication of the increase in energy expenditure during exercise is the production of more metabolic heat. Changes in body weight are caused almost entirely by changes in total body fluid content. 61-77. The Child and Adolescent Athlete. Of special relevance to sports that require fine motor skills and precision (e.g., gymnastics, figure skating, basketball) is a decrease in mental acuity. Temperature regulation during exercise in children and adolescents. Ward, and W.M. J. Appl. Park, and J.N. 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. 18: 4-9. Children will voluntarily drink more when the drink is tasty. Wilk, B., S. Kriemler, H. Keller, and O. Bar-Or (1998). Differences and changes in VO2 among young runners 10 to 18 years of age. Here, pediatric sports dietitians Lauren Furuta, MOE, RD, and Laura Watne, MS, RD, provide five tips that outline the best ways to feed active children, while helping them build lifelong healthy eating habits. 23: S29. Med. Depending on the type and intensity of exercise, they need more calories, more water, more protein, and more iron than inactive children. Switch from water to sports drinks after 1 hour of activity. Physiol. Bar-Or, O., R. Dotan, O. Inbar, A. Rothstein, and H. Zonder (1980). 31: S322. Drink composition, voluntary drinking, and fluid balance in exercising, trained, heat-acclimatized boys. Sci. Macdougall, J.D., P.D. Macdougall, D.S. Too often we hear about the millions of children and adolescents who are inactive, overweight, and obese. Brownell (1990). University of Glasgow, Glasgow, Scotland. In contrast, children and adolescents must maintain a positive nitrogen balance (i.e., a higher intake than utilization) for the purpose of growth and development of body organs and tissues. An ideal diet comprises 45% to 65% carbohydrates, 10% to 30% protein and 25% to 35% fat. Drinking was enhanced by a further 46% when the subjects drank a grape-flavored sports drink (Gatorade) that contained carbohydrate and NaCl. Wilson (1992). Nuts. If children are eating a good Whether children's preferential use of fat as an energy substrate has any implications for nutritional recommendations has yet to be determined. One should realize, though, that protein intake sufficient to meet the Recommended Dietary Allowance (RDA) may not guarantee an adequate nutritional status. Nutrient intake in young, highly competitive gymnasts. Roemmich (1990). Children and adolescents need adequate energy intake to ensure proper growth, development, and maturation. Protein requirements and muscle mass/strength changes during intensive training in novice bodybuilders. * During various athletic activities, children use more energy per kg body weight than do adults. Broadwell, J.L. Sci. Unpublished data (Riddell, personal communications) also suggest that during adolescence, younger boys burn relatively more fat and less carbohydrates during prolonged exercise than do older boys. 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). Analysis of data on respiration (Martinez & Haymes, 1992), concentrations of potential fat and carbohydrate fuels in the blood (Berg & Keul, 1988), and activities of muscle enzymes (Haralambie, 1979) suggest that, during prolonged exercise, children use relatively more fat and less carbohydrate than do adolescents or adults. Voluntary dehydration and heat intolerance in cystic fibrosis. Still, there is reason to assume that energy requirements of child athletes are different from those of adults. The Gatorade Sports Science Institute® was created to provide current Unless this extra heat is dissipated, core body temperature will increase; if extreme, this storage of heat in the body may induce heat-related illness. International Online: http://www.gssiweb.com/. Nelson (1998). The cause for the above differences in the use of energy sources is not clear. Sports Exerc. 73: 767-775. Nutritional Requirements of the Child and Teenage Athlete Author links open overlay panel Anne Z. Hoch DO, MD, PT Katie Goossen BS Tricia Kretschmer BS Show more However, experimental data yield inconsistent results about such an effect in child athletes. pp. For example, children aged 7-10 years must consume 1.1-1.2 g/kg per day, and children aged 11-14 need 1 g/kg per day (Ziegler et al., 1998). Åstrand, P-O. The meal itself should not be very different from what they've eaten throughout training. Creatine is one of the most popular nutritional supplements, with yearly sales over $300 million in the United States according to the ... Androstenedione. Energy Needs of Children During Exercise J. It is therefore essential to prevent or ameliorate voluntary dehydration in child athletes. Diet Assoc. Leibowitz, H.W., C.N. Unfortunately, our thirst mechanism, which determines our fluid consumption, almost invariably underestimates the actual fluid requirements during prolonged exercise. Brown and C.F. * One should make certain that children arrive fully hydrated for a practice session or for competition and enforce drink pauses every 15-20 min during prolonged activities, even when the child does not feel thirsty. 65: 150-157. Physiol. Sci. Horswill, C.A. Such insufficient drinking may result in "voluntary dehydration," i.e., dehydration that occurs even when beverages are offered in abundance. A physiological and nutritional profile of young female figure skaters. Oxford, England: Blackwell Scientific, pp. Children's Exercise & Nutrition Centre 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). Sport Nutr. Sawka, M.N., and K.B. Delistraty, D.A., E.J. Can. Children who do not drink enough to restore their body weights to normal between practices or competitions should be required to drink adequate fluids before they are allowed to participate in a subsequent practice or competition.

An adult athlete’s diet should typically be made up of 60% to 65% carbohydrates, whereas an adolescent athlete’s diet should contain 55% to 60%. 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). * Like adults, children underestimate their fluid needs during exercise lasting more than 30 min.
