Quizplus · Accepted Answer

The target heart rate range for this individual can be determined using the percentage of maximal heart rate method:

220 - age = 220 - 50 = 170 (maximal heart rate)
70% of maximal heart rate = 0.7 x 170 = 119
85% of maximal heart rate = 0.85 x 170 = 144

Therefore, the target heart rate range for this individual is between 119 and 144 beats per minute. Choice D is the only option that includes this range.
