QUESTIONS AND ANSWERS
Compare and contrast the curl-up and arm hang test and explain why different tests cannot be
used interchangeably. - ANS The curl-up tests the strength and endurance of the abdominal
muscles, while the arm hang tests the strength and endurance of the arm muscles. Since
different muscle groups are developed and tested in different ways, tests for different groups
cannot be used interchangeably because the results do not pertain to the same group of
muscles.
Which of the following is TRUE about assessing muscular strength and endurance? -
ANS Different muscle groups have to be tested separately.
Which of the following is a direct benefit of good flexibility? - ANS increased range of motion

, Explain why the greatest benefits to cardiorespiratory fitness come from sustained physical
activities like running, walking and cycling. - ANS Sustained physical activity allows the body
to work its muscles while providing oxygen to the muscle groups. This activity develops the
muscle groups in addition to the cardiovascular and respiratory systems that deliver oxygen to
the muscles via blood circulation. Sustained physical activity exercises all these systems in
concert and improves cardiorespiratory fitness levels.
Distinguish between different kinds of cardiorespiratory fitness assessments and explain why
different tests provide different information about fitness levels. - ANS There are several
different kinds of assessments of cardiorespiratory fitness such as timed runs, timed walks, and
step tests. The different tests assess the use of different muscle groups as well as different
levels of exertion. Running is more intensive than walking, and walking for a mile at a steady
pace over level ground uses different muscle groups than stepping up and down repeatedly.
Using multiple, different fitness assessments gives a more complete picture of the various
factors that contribute to an individual's level of cardiorespiratory fitness.
Explain why improving cardiorespiratory fitness and muscular strength and endurance are
considered good strategies for improving body composition. - ANS Exercise uses energy, and
when energy expenditure exceeds energy intake, the difference is made up by burning fat.
Thus, improving one's cardio respiratory fitness and muscular strength and endurance can help
improve one's body composition by changing the ratio of body tissue to fat.
