Document Summary

20-25% of kcal should come from fat for most athletes. We should still pick healthy fats, even if we happen to be a star athlete! Lower body fat leads to lower sex hormone levels female athlete triad. Can also affect bone mineral density also male athlete triad. To provide protein for producing enzymes and other body proteins. But most athletes easily consume adequate amounts with a normal mixed diet and can get this amount of protein from food alone. The general population (least) needs 0. 8kg/kg body weight. Endurance athletes (middle) need 1. 2-1. 4 g/kg body weight. Strength athletes (most) need 1. 2-1. 7g/kg body weight. Low fat, low sodium sources like fish and legumes are best sources of protein. Some athletes who may not get enough protein! Adolescent athletes teens need a lot for micro and macro nutrients just for growing. Those with low body weights aiming for a weight category (boxers, wrestlers)

Alex, Kim, and Jenna have different levels of activity, and thus require a varied amount of calories per day. Alex is an athlete, and he requires 3500 calories per day to fuel his high intensity activity. Jenna is a secretary and is sedentary most of her day. Her low level of activity requires a mere 1800 calories a day, while Kim, a professional dancer, needs 2800 calories per day to fuel her moderate level of activity.

Profession	Secretary	Professional Dancer	Athlete
Level of Activity	Low	Moderate	High
Caloric Needs	1800 Calories/Day	2800 Calories/Day	3500 Calories/Day

Fats are broken down in cellular respiration to generate the ATP needed to fuel our bodies. According to the Food and Drug Administration (FDA), the Percent Recommended Daily value for fats in a balanced diet should not exceed more than 30% of the total daily calorie intake. Fats provide 9 calories per gram.

Nutritional needs of Jenna

What question would this calculation answer?
Finding 30% of 1800 calories and then dividing by 9 calories per gram.
1800 calories x 0.30 = 440 calories
440 calories/9 calories per gram = 49 grams

Multiple Choice

How many grams of fat can Jenna consume in one meal?

How many fat calories can Jenna consume each day?

How many calories are found in 9 grams of fat?

How many grams of fat can Jenna consume each day?

move electrons through the cell membrane.

Part 5

As protons move through the proton pump,

Multiple Choice

the membrane becomes more permeable to the hydrogen ions.

the concentration of hydrogen ions inside and outside the cell reaches equilibrium.

they build up on one side of the membrane, producing a concentration gradient.

conformational changes occur within the membrane proteins.

Part 6

Sample Case Study

Mrs. King is a 43-year-old married mother of four. Mrs. King is 5â 4â tall, weighs 160 pounds, and has a history of mild hypertension. Her blood pressure is controlled with a low-sodium diet, and although her doctor told her for years that she should exercise, she tried running but found it unpleasant and discontinued all forms of exercise. She is currently sedentary. Her grandmother died as a result of heart disease from years of diabetes and high cholesterol.
