Lesson 02: It’s All in the Details – Multiple Choice Quiz

Warm-ups primarily prepare the body for activity by:

• lowering body temperature and slowing blood flow

• increasing body temperature and making soft tissues more pliable

• immediately building muscle mass

• reducing the need for hydration

Which of the following is an example of a force acting on the body?

• Your body moving through water

• The color of your workout clothes

• The song playing while you exercise

• The day of the week you exercise

Momentum is best defined as:

• force divided by distance

• mass times acceleration

• weight times speed (velocity)

• energy plus time

In biomechanics, “leverage” refers to:

• the length of your phone charger

• the tension created in muscles when they apply pressure around joints (bones act as levers)

• the number of repetitions you do

• how much water you drink during exercise

5. The activity that primarily relies on balance is:

• Tightrope walking

• Reading a book

• Playing chess

• Typing on a computer

To measure your resting heart rate (RHR) as the lesson suggests, you should:

• Count beats for 60 seconds while running

• Count beats for 30 seconds right after jumping jacks and multiply by two

• Count beats for 30 seconds while lying still just after waking, then multiply by two

• Use a calculator to estimate without measuring

The simple formula given for estimating Maximum Heart Rate (MHR) is:

• 180 – age

• 220 – age

• 200 – age

• age × 2

According to the lesson, moderate intensity exercise is about what percent of MHR?

• 20–40%

• 50–70%

• 75–95%

• 90–100%

Vigorous intensity exercise target percentage of MHR (as listed) is approximately:

• 10–30%

• 30–50%

• 50–70%

• 70–85%

Heart Rate Reserve (HRR) is calculated by:

• MHR + RHR

• MHR – RHR

• (MHR × RHR) ÷ 2

• RHR – MHR
