Praxis 5857 Practice Test Practice Question
The physical education teacher provides students all heart rate monitors during a twenty-minute aerobic activity. This type of technology will primarily provide students with feedback on which of the following?
Correct Answer: A
Rationale: Heart rate monitors primarily measure the heart's response to physical activity, providing real-time feedback on cardiovascular exertion. This data helps students gauge their fitness level, as a lower resting heart rate and appropriate heart rate during exercise indicate better cardiovascular health.
Option B, muscular strength, focuses on the maximum force a muscle can exert, which heart rate monitors do not measure. Option C, body composition, relates to the proportion of fat and muscle in the body, requiring different assessment methods. Option D, muscular endurance, involves sustaining activity over time, which is not directly reflected by heart rate alone.
