NSC101 Exam Questions
All of these are components of fitness EXCEPT _____ - ANS: grip strength
__________ is the process of building muscle because of use and strength training, and and ________- is
the process of the reduction in muscle mass due to disuse - ANS: hypertrophy, atrophy
T/F: Aerobic systems are used during bouts of high-intensity exercise, such as sprinting, and produce the
byproduct, lactate. - ANS: False, its Anaerobic
Which nutrient is essential for people who exercise regularly? - ANS: carbohydrates
T/F: The timing of eating carbohydrates is not important for effective performance. - ANS: False
What are essential benefits of fitness? - ANS: improved energy levels and lower chronic disease risk
Despite the indisputable benefits of physical fitness, only ______% of the U.S. population meets all the
Physical Activity Guidelines for Americans. - ANS: 20%
What do the Physical Activity Guidelines outline? - ANS: A balance of aerobic activity, resistance training
and intensity of exercise needed to maintain or improve cardiovascular health
What is the accepted measure of a person's cardiorespiratory fitness? - ANS: the rate at which the
tissues consume oxygen
Why is a consistent, disciplined program of physical activity so important? - ANS: It builds the muscle
tissues and metabolic equipment needed for the activities that are repeatedly called upon to perform.
, Muscles performing high-intensity work for more than a few seconds rely on the _______ to make ATP -
ANS: lactic acid system
When muscle cells' energy reservoir diminishes, ______ and ______ break down nutrients to help
restore energy. - ANS: aerobic; anaerobic
What is Excess Post-Exercise Oxygen Consumption, also known as EPOC? - ANS: the phenomenon that
following intense periods of exercise the body's metabolism stays high for several minutes or hours,
expending extra fuels [calories] even during rest
Why is carbohydrate so essential? - ANS: Restores the body's glycogen stores which deliver the energy
needed for top performance.
What role does the ingestion of protein play in improving fitness? - ANS: Delivers the critical amino acids
necessary to build and maintain muscle and other lean tissue
What physical activity performance is enhanced by nutrient supplements? - ANS: none; A proper diet
that is followed diligently provides sufficient nutrients for the body.
A vegetarian diet should prioritize vitamin ______ to enhance essential iron absorption from foods -
ANS: C
Why is iron essential to improving the body's fitness? - ANS: It must be present to deliver oxygen to the
working muscles.
What are the three minerals lost through profuse sweating from physical exertion? - ANS: chloride,
potassium, and sodium
Why is ordinary cool water the preferred form of hydration? - ANS: Water rapidly leaves the digestive
tract to enter the tissues and cools the body from the inside.
