Michael is a 33 year old veteran of the Marine Corps.
Since leaving the military ten years ago, Michael has been working as a
salesman, where he spends most of his day at a desk. When he enlisted at the
age of 18, he weighed 156 pounds. At the end of his military service he was 181
pounds, and today he weighs 190 pounds (ht = 5’11”). Although his weight has
not changed much since leaving the military, he began to feel he was getting
out of shape because of his sedentary lifestyle. He has recently begun
exercising again and is trying to improve his diet in order to “get toned.” He
is started strength training with a personal trainer twice per week, and runs
for 20-30 min 1-2 times per week. Michael’s diet contains a lot of food from
restaurants such as Chipotle and Panera, in addition to protein shakes, which
he often has each morning and before training. A 24-hr recall reveals that with
his protein shakes, Michael is consuming ~110 grams of protein daily. Michael
comes to you because he wants to train for the Marine Corps Marathon. His
proposed plan is to increase his running to 1-2 hours per day, 5-6 days per
week, and continue his weight training.
1. What
are the Physical Activity Guidelines for Americans? How does Michael’s current
level activity measure up to them? Are there changes he should make to reach
these recommendations?
2. How
does his current intake compare to his estimated protein needs? Do you
recommend Michael continue using his protein supplement? Discuss the pros and
cons of using a protein supplement.
3. Michael
is nervous about drinking enough water for his long runs. How would you advise
Michael regarding his fluid consumption? Do you recommend beverages other than
water? Why or why not?
4. What
are Michael’s carbohydrate needs based on his current exercise? If he increased
his running to begin marathon training, how would you recommend he change his
carbohydrate intake?
5. As
Michael continues to train, he will be able to run longer and faster. Explain
what the physiological effects are of Michael’s training that will enable this.
