The ability to perform moderate to vigorous physical activities on a regular basis and to complete daily tasks without undue fatigue demonstrates
physical fitness
aerobic literally means
with oxygen
The ability of the heart, lungs, and blood vessels to supply oxygen to skeletal muscles during sustained physical activity is
cardiorespiratory fitness
The fitness of a person’s cardiorespiratory system is assessed by measuring
the volume of oxygen the muscles consume during exercise.
Swimming, cycling, and jogging are examples of
) aerobic activities.
) Muscular strength is the amount of forcevz
a muscle is capable of exerting in one contraction.
) Muscular endurance is a muscle’s ability to
exert force repeatedly or to sustain a contraction for a length of time
Which of the following describes the most common method used to measure muscle strength?
Maximum weight that can be moved at one time
Regular exercise reduces the risk for cardiovascular diseases by
improving blood flow and strengthening the heart muscle
11) Aerobic capacity is measured by
) VO2 max.
The range of motion possible at a particular joint or series of joints is
flexibility
Which of the following changes could an individual expect from participating in regular aerobic exercise?
increase in HDLs
14) Which of the following is true regarding exercise and cancer?

200
The easiest way to check to make sure you are walking or running with enough intensity to improve cardiorespiratory fitness is to
use the talk test.
The maximum amount a person can lift in one contraction is a measurement known as
one repetition maximum (1 RM).
) Muscular strength is best developed by
overloading the muscles to force them to adapt.
