Chloe is a 21-year-old woman who has taken up running in an effort to lose weight and improve her endurance. She runs 3 to 4 days a week for approximately 45 minutes to an hour. She can’t seem to finish the last 15 minutes of her hour run and has to walk. At the store, she finds a sports “energy gel” labeled as a “natural performance enhancer.” Each 1.1-ounce package provides 100 kcalories (25 grams total carbohydrates), 40 milligrams sodium, and 30 milligrams potassium. The directions read: “For best results, consume one package 15 minutes before activity, one to two packages per hour during activity and one package immediately after activity to aid in recovery. Always follow consumption with water.” Chloe thinks this may help her finish her hour run, but is still not sure whether she needs this product for her training regimen   

1.    Based on information in your text, what main ingredient in this product would Chloe expect to be a “natural performance enhancer”? 

a.     Sodium

b.     Potassium

c.     Glucose

d.     Beta-alanine

e.     Ribose

1.    Considering her current level of activity, what is the most important nutrient that Chloe needs to consume before her workout?

a.     Sodium

b.     Sucrose

c.     Water

d.     Calcium

e.     Glucose

2.    When Chloe starts her runs, which energy system is used first?

a.        Phosphagen system

b.        Lactic acid system

c.        Aerobic system

4.  How long can this energy system you selected in #3 above provide energy?

a.     about 10 seconds

b.     about 1 minute

c.     about 3 minutes

d.     8 to 10 minutes

e.     > 20 minutes

5.    What ingredient in this energy product might “aid in recovery” after physical activity? . 

a.     Sodium

b.     Potassium

c.     Glucose

d.     Beta-alanine

e.     Ribose

6.    Given the length of her workouts, what would you advise her to do to enhance glycogen storage so she doesn't need to use the energy gel? (2 points)

She should consume high-carbohydrate food after her run to increase the glycogen storage.

7.    Chloe doesn’t drink water during her hour runs, but is well aware of the risks of dehydration and decides to monitor her fluid status by weighing herself before and after her hour runs. She finds that she is losing 1.5 lbs. after these runs. How much water would you tell her to drink during her hour runs? Show your calculations. You may use the information from the Ch14 lecture. (2 points)

Sweat rate= (A + B)/C

                    24+0/1=24 ounces of water……. (1.5 lb = 24 ounces (A), she is not consuming any water so B=0 and she is running for one hour so C=1)
