Question 1

Which of the following tests uses calipers to assess body composition?

Revolt · Accepted Answer

skinfold test

Question 2

Which of the following is a direct benefit of good flexibility?

Revolt · Accepted Answer

increased range of motion

Question 3

Which of the following exercises would be BEST for improving muscular strength and endurance?

Revolt · Accepted Answer

push-ups

Question 4

Distinguish between different kinds of cardiorespiratory fitness assessments and explain why different tests provide different information about fitness levels.

Revolt · Accepted Answer

Cardiorespiratory fitness can be assessed with lab tests like direct VO2 max measurement on a treadmill or bike ergometer that give precise oxygen use data, or field tests such as the 1-mile run, 12-minute run, or step test that estimate fitness from performance time or heart rate recovery. Different tests provide different information because lab tests measure peak aerobic capacity directly while field tests assess sustained endurance or recovery under practical conditions, and each may target slightly different intensities or muscle involvement.

Question 5

Explain why the greatest benefits to cardiorespiratory fitness come from sustained physical activities like running, walking and cycling.

Revolt · Accepted Answer

Running, walking, and cycling performed continuously keep the heart rate elevated and engage large muscle groups for an extended time. This trains the heart, lungs, and blood vessels to deliver and use oxygen more efficiently, leading to greater improvements in cardiorespiratory fitness.

Question 6

Which of the following is NOT a benefit of cardiorespiratory fitness?

Revolt · Accepted Answer

The efficiency of the respiratory system increases.

Question 7

Which of the following is TRUE about assessing muscular strength and endurance?

Revolt · Accepted Answer

Different muscle groups have to be tested separately.

Question 8

Explain why improving cardiorespiratory fitness and muscular strength and endurance are considered good strategies for improving body composition.

Revolt · Accepted Answer

Cardiorespiratory exercise increases calorie use and helps reduce body fat, while muscular strength and endurance training builds and maintains lean muscle. Together, they improve the balance between lean tissue and body fat, resulting in healthier body composition.

Question 9

Compare and contrast the curl-up and arm hang test and explain why different tests cannot be used interchangeably.

Revolt · Accepted Answer

Curl-up measures abdominal endurance; arm hang measures upper-body strength/endurance. Tests target different muscle groups so results are not interchangeable.

Question 10

Explain the relationship between muscular strength and endurance and describe their impact on health-related fitness.

Revolt · Accepted Answer

Muscular strength is the maximum force a muscle can produce in one contraction; muscular endurance is the ability of a muscle to contract repeatedly over time. Both contribute to health-related fitness by supporting daily activities, improving posture, reducing injury risk, increasing lean body mass, and enhancing overall physical function and metabolic health.
