1. Jenna, a young black professional tennis player, is seeking to raise her game to another level. She has contacted you for sports nutrition counseling. You want to recommend a pattern of food intake using the Dietary Exchange System. Based on a careful analysis of her typical food intake, you estimate that she consumes 3000 calories per day. You are recommending that she consume 7gCHO/kg BW and 1.4gPRO/kg BW. Jenna weighs 150 pounds and is 6'1" tall. Her usual intake of dairy products (yogurt only, due to her lactose intolerance) is 1 serving. She consumes 6 servings of vegetables per day and 15 servings of fruit and fruit juices per day. 1. Calculate a daily meal plan using dietary exchanges. CLEARLY show your work if you want any partial credit for an incorrect final answer. (10 points)2. Jenna is hearing a lot about the high protein, low carbohydrate diets that are the rage across the nation. Jenna is interested in trying one of these diets in order to bulk up. One of her advisors is recommending a diet with 50% protein, 30% fat, and 20% carbohydrate. What is your advice to Jenna? Explain. (10 points)3. Jenna trains in Florida where conditions are generally very warm and humid. Typically, she has two 2-hour workouts a day. Most of the workouts are tennis skill drills or conditioning drills that require almost constant movement. In addition, they include a 1 hour weight training session 3 times a week. After a typical 2 hour workout, her weight drops by about 4 pounds despite drinking two pints of a sports drink. By the next morning, she has consumed enough to be back at her normal weight. What is your recommendation regarding her hydration program? What should her minimum fluid consumption be the next time she works out? Explain.

One of her advisors isrecommending a diet with 50% protein, 30% fat, and 20% carbohydrate. What is your advice to Jenna? Explain. (10 points)This would be a poor training diet for any athlete. All athletes need diets moderately high in carbohydrate in order to replace the glycogen used during their intense workouts. Eating a low carbohydrate diet (this diet provides only 2.2gCHO/kgBW) prevents adequate synthesis of glycogen and would lead to glycogen depletion and compromise her workouts. In addition, there is little evidence that a diet this high in protein (5.5gPRO/kgBWW) provides any benefit towards increasing muscle mass/protein synthesis.3.
