Sports Nutrition Assignment IIJamar is a 17-year old high school junior who has a chance of starting as a linebacker on the football team his senior year. He is 6 feet tall and weighs 175 pounds. His coach has recommended that he gain 10-15 pounds over the next 8 months, but not at the sacrifice of his speed and quickness. Jamar eats home-cooked, well-balanced meals for breakfast and supper. Breakfast usually consists of two scrambled eggs, 8 oz. skim milk and 2 slices of bacon (8 grams of protein total for bacon). At breakfast he also drinks a mega-protein supplement that contains 56 grams of protein. For school, he packs his own lunches, which usually include two chicken breast sandwiches (3 oz. each; 2 slices of whole-wheat bread each) with potato chips and skim milk (8 oz). He also has a mid-morning and mid-afternoon snack, which typically consists of a protein bar (24 grams of protein/bar). He works out in the high school weight room two to three times per week in the late afternoon. When he arrives home, he studies until the family eats supper, around 7 pm. His usual protein intake during dinner is about 40 grams of protein. His final snack of the day occurs just before bedtime, when he consumes another mega-protein supplement that contains 56 grams of protein.Calculate the total amount of protein that Jamar is getting in his diet on a daily basis. Show your work.2 scrambled eggs: ~12 grams proteinSkim Milk: ~3.1 grams protein2 Slices Bacon: ~8 grams proteinMega Protein Supplement:~ 56 grams protein2 3 oz chicken breasts: ~ 27 x 2= 54 grams protein4 slices whole wheat bread: ~3.1 x 4= 12.4 grams proteinPotato chips: (Lays Wavy) 2 grams proteinSkim Milk 8 oz: ~ 3.1 grams proteinSnack bars: 24 x 2=~48 grams proteinDinner: 40 grams proteinPre- bedtime supplement: 56 grams?Total daily protein: 294.6Based on the RDA for dietary protein, what is the recommended daily amount of dietary protein for Jamar? Is Jamar getting enough dietary protein to achieve his goals?Jamar weighs 175 lbs which is 79.37 kg. The RDA for protein is 0.8 g/kg body weight for adults so his RDA is 63.496 grams of protein. Jamar is getting beyond enough dietary protein to reach these goals.Based on the recommendation for resistance-trained athletes (these are given in the class notes), is Jamar getting enough dietary protein? Justify your answer.Jamar weighs 175 lbs which is 79.37 kg. Even at the upper limit of the general recommendations, Jamar should be getting about 158.74 grams of protein. His daily intake of 135.9 grams greater than the general recommendations might impact his overall performance and weight gain.Is it detrimental to consume a diet containing too much protein? What should we know about Jamar to better address this question?Extreme excess protein can lead to excessive weight gain in the form of fat and kidney disease (because the body is processing it and excreting it out in the form of urine). Some studies have also shown it to be correlated with prostate cancer. (?(Links to an external site.)?)We would need to know about the timing of his resistance exercise and cardio in correlation with the protein intake.An assessment of his nitrogen protein balance would also be useful if we could do this efficiently. Using the measures of 3-methylhistidine in his urine would assess the usage of this excessive protein in his diet.What recommendations would you give Jamar about his daily protein intake?Jamar should attempt to lower some of his protein intake. Keeping his intake at about 2 g/kg body weight would prevent him from adding extra fat to his body. Body fat would highly impact his performance. (Especially his speed).He should also attempt to strategically spread out his high protein meals so that they are in correlation with his resistance training (immediately after) and including some prior to sleep (~40 g instead of 56 g) is a habit he should still maintain.Educating him on the fact that only 20 grams of protein per meal is maximally effective would also encourage him to spread out his protein intake better. ................
