Question

the greatest health risk factor which a person can control ______.

• 1 point
• heart attack
• cancer
• inactivity
• heredity

to increase flexibility you must include ______.*
1 point

• stretching exercises
• cardiovascular exercises
• muscular endurance exercises
• weight training

which of the following is not a benefit of warming up before beginning to exercise?*
1 point

• generates heat in the muscle and joint tissues
• lowers heart rate
• helps you mentally focus for the exercise
• helps prevent injury

Explanation:

Analyze risk factors

We evaluate controllable health risks.
Using the Cardiovascular Disease Risk Factors knowledge point:

• Heredity is genetic and cannot be controlled.
• Heart attack and cancer are medical conditions, not direct behavioral risk factors themselves.
• Inactivity is a major behavioral risk factor that a person can directly control.

Analyze flexibility requirements

We identify how to increase joint range of motion.

• Cardiovascular, muscular endurance, and weight training focus on aerobic capacity and strength.
• Stretching exercises specifically target muscle-tendon units to increase flexibility.

Analyze benefits of warming up

We evaluate physiological responses to a warm-up.

• Warming up generates heat in tissues, increases mental focus, and helps prevent injury.
• Warming up increases heart rate to prepare the cardiovascular system; it does not lower it.

Answer:

Question 1

• heart attack
• cancer
• inactivity (Correct answer)
• heredity

Question 2

• stretching exercises (Correct answer)
• cardiovascular exercises
• muscular endurance exercises
• weight training

Question 3

• Generates heat in the muscle and joint tissues
• Lowers heart rate (Correct answer)
• Helps you mentally focus for the exercise
• Helps prevent injury
