Final answer:
The equation to calculate the heart rate goal for an athlete is G = H + R, where G is the goal heart rate, H is 70% of the heart rate reserve, and R is the resting heart rate.
Step-by-step explanation:
The equation which represents the heart rate goal for a particular athlete is G = H + R, where G is the goal heart rate, H is 70% of the heart rate reserve, and R is the resting heart rate. To calculate the heart rate goal, you need to calculate 70% of the heart rate reserve and add it to the resting heart rate.
For example, if the resting heart rate is 60 bpm and the heart rate reserve is 40 bpm, the heart rate goal would be 60 + 0.7(40) = 60 + 28 = 88 bpm.
