Describe the components of health-related fitness.

Answer:

The components of health-related fitness are cardiorespiratory endurance, muscular strength, muscular endurance, flexibility, and body composition. Cardiorespiratory endurance is the ability of the heart and lungs to supply oxygen during sustained activity. Muscular strength is the greatest force a muscle can produce, while muscular endurance is its ability to keep working over time. Flexibility is the range of motion around a joint. Body composition is the proportion of fat, muscle, bone, and other tissues in the body.

16

Explain why living a healthy lifestyle is the most important step in preventing cardiovascular disease.

Answer:

A healthy lifestyle is important because many cardiovascular disease risk factors can be reduced through everyday choices. Regular exercise, a balanced diet, maintaining a healthy weight, avoiding tobacco, and limiting alcohol can help control blood pressure, cholesterol, and blood sugar, lowering the chance of developing heart and blood vessel disease.

18

Why is physical activity so important in preventing heart disease?

Answer:

Physical activity strengthens the heart and improves circulation. It also helps control weight, blood pressure, cholesterol, and blood sugar, reducing several major risk factors for heart disease.

19
