FTCE Physical Education K-12 Practice Test

Which of the following is NOT a physiological benefit of regular physical activity?

1. Lower resting heart rate

2. Increased muscle mass and body fat

3. Improved flexibility

4. Improved cardio-respiratory fitness

The correct answer is: Increased muscle mass and body fat

The choice that indicates an increase in muscle mass and body fat as a physiological benefit of regular physical activity is not accurate. Regular physical activity is known to lead to a decrease in body fat and an increase in lean muscle mass. Engaging in consistent exercise improves overall body composition, which is characterized by a higher ratio of muscle to fat. Lower resting heart rate, improved flexibility, and enhanced cardio-respiratory fitness are well-established physiological benefits of regular physical activity. These benefits contribute to overall health, better performance in physical tasks, and the prevention of chronic diseases. Therefore, the assertion that regular physical activity would lead to increased body fat contradicts the established effects of exercise on the body.
