HLTH 645 Exam 2
The body uses carbohydrates primarily in the form of fruit sugar, or fructose. -
ANS-False: The predominant form of carbohydrate used by the body is glucose and its
storage form, glycogen.
Sugars such as sucrose (table sugar) are unhealthy and should rarely be a part of an
athlete's diet. - ANS-False: Although excessive consumption of sugars may be related
to obesity and other long-term health concerns, there are specific circumstances in
which the consumption of sugars may be advantageous for athletes (i.e. sport drinks
during endurance exercise and high glycemic-index food immediately following
exercise). That said, athletes should get the majority of their carbohydrates from
plant-based foods and high-fiber complex carbohydrates.
Low levels of muscle glycogen and blood glucose are often associated with fatigue,
particularly during moderate- to high-intensity, long-duration endurance exercise. -
ANS-True
A diet that contains 70 percent of total kilocalories as carbohydrates will provide the
necessary amount of carbohydrates for an athlete. - ANS-False: This statement could
be true if the total amount of energy (kcal) consumed by the athlete is sufficient. An
athlete's diet may contain 70 percent of its energy from carbohydrate but an insufficient
number of grams of carbohydrate if the athlete's diet is very low in total calories.
Most athletes consume enough carbohydrates daily. - ANS-False: Most athletes fail to
consume the recommended amount of carbohydrate daily and risk having low muscle
and liver glycogen stores, which could negatively affect training and performance.
Skeletal muscle is the primary site for protein metabolism and is the tissue that
regulates protein breakdown and synthesis throughout the body. - ANS-False: Skeletal
muscle is an important site for protein metabolism, but the liver plays a primary role both
in protein metabolism and its regulation.
In prolonged endurance exercise, approximately 3 to 5 percent of the total energy used
is provided by amino acids. - ANS-True
To increase skeletal muscle mass, the body must be in positive nitrogen balance, which
requires an adequate amount of protein and energy (calories). - ANS-True
