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

Hint: What is the FIT formula for vigorous aerobic activity? 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. (continued)

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 Read the Taking Charge feature: Self- Confidence. Answer the For Discussion questions. 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.
