How does cardiovascular fitness benefit the heart?

• Cardiovascular fitness benefits the heart by causing irregular heartbeats

• Cardiovascular fitness benefits the heart by improving the efficiency of the heart muscle, increasing blood flow, reducing the risk of heart disease, and lowering blood pressure.

• Cardiovascular fitness benefits the heart by decreasing blood flow

• Cardiovascular fitness benefits the heart by increasing cholesterol levels

What is the target heart rate zone for cardiovascular workouts?

• 50-85%

• 60-90%

• 40-75%

• 55-80%

What are some examples of cardiovascular exercises?

• Yoga

• Running, cycling, swimming, jumping rope, dancing

What is the difference between aerobic and anaerobic exercise?

• Aerobic exercise requires oxygen, while anaerobic exercise does not.

• Aerobic exercise is done indoors, while anaerobic exercise is done outdoors.

• Aerobic exercise focuses on strength training, while anaerobic exercise focuses on cardiovascular endurance.

• Eating junk food regularly

• Avoiding physical activity

What role does genetics play in cardiovascular fitness?

• Genetics has no impact on cardiovascular fitness

• Cardiovascular fitness is solely determined by diet

• Genetics can influence cardiovascular fitness by determining factors such as heart size, blood vessel structure, and response to exercise.

• Everyone has the same genetic predisposition for cardiovascular fitness

Why is it important to monitor heart rate during cardiovascular exercise?

• To ensure the intensity of the workout is appropriate and safe.

• To track the weather conditions

• To count the number of steps taken
