Can You . . .

• . . . define vigorous aerobic activity and list several examples?

• . . . describe the FIT formula for developing cardiorespiratory endurance?

• . . . calculate target heart rate zone for building cardiorespiratory endurance using two different heart rate methods?

• . . . describe three guidelines for building self-confidence?

What is vigorous aerobic activity?

Vigorous Aerobic Activity

• Vigorous aerobic activities are intense enough to elevate your heart rate above your threshold of training and into your target zone for cardiorespiratory endurance.

• Vigorous aerobic activities build cardiorespiratory endurance.

What are some examples of vigorous aerobic activities?

Vigorous Aerobic Activities• Examples: Jogging,

aerobic dance, biking, swimming, stair stepping

• FIT formula for vigorous aerobics (step 2) and vigorous sport and recreation (step 3):

F = 3+ days per week

I = Reach target heart rate

T = At least 20 min/day

How much vigorous physical activity is enough to build cardiorespiratory fitness?

Hint: What is the FIT formula for vigorous aerobic activity?

FIT Formula for Vigorous Aerobic Activity

• Frequency: at least 3 times per week

• Intensity*: above threshold heart rate

• Time: 20 minutes per day

*Intensity for beginners (sedentary people) is different than for regular exercisers.

Review Fitness Target Zone

How do you calculate a target heart rate zone for someone who

participates in some vigorous activity?

Calculating Target Heart Rate Zones

• Percent of maximal heart rate (% max HR)

– Need a max HR*

• Percent of heart rate reserve (% HRR)

– Need a resting and a max HR*

*Max HR can be true or estimated max HR.

Target HR Range Using % max HR Method

• Step 1: 220 – age = estimated max HR.

• Step 2: estimated max HR × .60 (threshold %) = threshold heart rate.

• Step 3: estimated max HR × .80 (threshold %) = target ceiling heart rate.

Threshold HR Using Percent of Heart Rate Reserve (% HRR) Method

• Step 1: 220 − age = estimated max HR.

• Step 2: estimated max HR − resting heart rate = heart rate reserve (HRR).

• Step 3: HRR × .60 + resting heart rate = threshold heart rate.

Target Ceiling HR Using % HRR Method

• Step 1: 220 − age = estimated max HR.

• Step 2: estimated max HR − resting heart rate = heart rate reserve (HRR).

• Step 3: HRR × .80 + resting heart rate = target ceiling heart rate.

Group Activity 1

1. Read the Taking Charge feature: Self-Confidence.

2. Answer the For Discussion questions.

3. Be prepared to discuss your answers with the class.

Taking Charge: Self-Confidence

• For Discussion:

– What are some reasons that people lack self-confidence? How can they increase their self-confidence?

– What advice can you give Tony to get him to try new activities and stick with them?

– What advice can you give Mei to help her be more comfortable in social situations?

What are some skills for building self-confidence?

Skills for Building Self-Confidence

• Learn a new way of thinking.

• Set your own standards for success.

• Avoid competition if it causes you a problem.

• Set small goals that you’re sure to reach.

• Think and act on positive—not negative—ideas.
