A fitness tracker shows Jordan's heart rate during a workout: 92, 118, 135, 158, and 122 beats per minute. Which reading is the highest intensity moment?

A student's target heart rate zone for vigorous activity is 150 to 180 beats per minute. During soccer practice, their heart rate is 162 beats per minute. Is the student in the vigorous zone?

Lina checks her heart rate right after jogging and again one minute later. Right after jogging, it is 168 beats per minute. One minute later, it is 132 beats per minute. How much did her heart rate decrease?

Recovery heart rate is how much the heart rate drops after exercise. A larger drop during the first minute often shows better recovery. Student A drops from 170 to 140 beats per minute. Student B drops from 165 to 150 beats per minute. Which student had the larger one-minute recovery drop?

Use this zone guide: light activity is 50% to 60% of maximum heart rate, moderate activity is 60% to 70%, vigorous activity is 70% to 85%, and near maximum is 85% to 100%. A student has a maximum heart rate of 200 beats per minute and is exercising at 150 beats per minute. What percent of maximum heart rate is this, and which zone is it?

During a bike ride, Sam records these heart rates every 5 minutes: 105, 128, 142, 146, 138, and 120 beats per minute. What is the range of the heart rate data?
- 9
A student wants to stay in a moderate zone of 120 to 150 beats per minute. Their heart rate readings are 116, 124, 139, 151, and 147 beats per minute. Which readings are in the moderate zone?

A class compares average resting heart rates before and after four weeks of regular activity. The average resting heart rate was 78 beats per minute before and 74 beats per minute after. What changed, and by how much?
- 11
Explain why a person's heart rate usually increases during exercise.

A cool-down walk helps heart rate return toward resting level. Kai's heart rate after exercise is 160 beats per minute. After 2 minutes of walking, it is 128 beats per minute. After 4 minutes, it is 104 beats per minute. Describe the trend in Kai's heart rate.
