Question

mason joined the water polo team at his school. as part of his conditioning, masons coach requires a 25 - minute run during practice. masons heart rate reaches 125 beats per minute, but his target heart rate zone is 138 - 183 beats per minute. what should mason do to get the most benefit for his heart? (3 points)
○ increase the amount of time he runs
○ increase the speed at which he runs
○ decrease the amount of time he runs
○ decrease the speed at which he runs

Explanation:

To reach the target heart rate zone (138 - 183 bpm) from his current 125 bpm, Mason needs to increase the intensity of his run. Increasing running speed raises exercise intensity, which typically increases heart rate. Increasing run time (without increasing intensity) may not sufficiently raise heart rate, and decreasing time or speed would lower or not raise his heart rate enough. So increasing speed is the correct approach.

Answer:

B. Increase the speed at which he runs
