HNF 150 Exam 2 Study Guide
1. Risk of dieting: It will not create weight sustainability, causing your weight
to cycle. Increase in: eating disorders, disordered eating, body hatred, excursive
addiction, excursive resistance, weight cycling, smoking, discrimination, shame &
isolation, wasted resources.
2. Describe the % efficiency for dieting as a treatment for obesity: It rarely works
because once the diet is over they gain it back.
3. Weight Cycling: when your weight increases and decreases due to dieting.
4. Sports Nutrition and why it is important: sports nutrition is a nutrition pattern that
incorporates the correct nutrient balance and timing of intake to optimize per-
formance goals and overall health status. Nutrition is a key foundation to
optimizing training and performance and short and long term health status
5. 3 Nutritional Priorities of Sports Nutrition: carbs, fat, protein
6. 3 energy systems available: ATP-PC turbo charge short (Anaerobic), Glyco- gen-
Lactate (Anaerobic) Turbo Long, Aerobic Systems. Aerobic glycolysis, fatty acid
oxidation
7. ATP-PC duration and availability: 1-10 sec, phospho-creatine
8. Glycogen- Lactate duration and availability: 1-90 sec, Glycogen/ CHO 2 PRO
9. Aerobic glycolysis & Fatty acid oxidation duration and availability: up to 2 hours,
Glycogen, Fatty Acids, 3 PRO

, 10.General Structure of Proteins: proteins are polymers composed of amino
acids linked together by peptide bonds to form a polypeptide chain
11.three components of amino acids: an amine group at one end, an acid group at
the other, and a distinctive side chain
12.How many essential amino acids are there: 10
13.why are adequate amounts of all the essential amino acids required for protein
synthesis: without them the body cannot make the proteins it needs to work. They
can only be replenished from foods so a person must frequently eat the foods that
provide them
14.What factors differentiate proteins: shapes such as globular. hollow balls, and
tendons
15.7 roles of protein in the body: Building blocks, hormones, catalytic, transport of
oxygen,blood clotting,immunity, and muscle contractibility
16.Role of protein as building blocks: proteins make up the hair, nails, muscles, etc
17.Role of protein in hormones: control growth and metabolic activities of the
body.
18.Role of protein in catalytic activities: enzymes are globular protein. Enzymes
speed up the biochemical reactions and help in digestion.
19.Role of protein in the transport of oxygen: protein called hemoglobin contain iron
aton which temporarily links with oxygen and releases it throughout the body
20.role of protein in blood clotting: fiberirogen is a glycoprotein which helps in
