The correct answer is C, it is both stimulant and depressant.
Answer: option d= 130 - 150.
Explanation:
From the question, we are given that the man's age= 50, the man weighs= 193 lb (87.5 kg) and the 50 years old man's resting heart rate= 70 beats · min-1. Then, I am asked to calculate the man's target heart rate (THR) zone for 60% to 80%.
Using the Karvonen (HRR) method to calculate the fifty(50) years old man's target heart rate (THR) zone for 60% to 80%, we will need the man's age for this Calculation and the man's resting heart rate (HR).
Important information to note that is not given from the question is that the 50 years old man's estimated maximum heart rate is (220 - 50) = 170.
Step one: Using the formula; maximum heart rate - man's age × zone Percent. --------------------------(1).
Step two: equation (1) + resting heart rate (HR). -------------------------(2).
For the 60 percent = 0.6.
==>( 170 - 70) × .6 = 60.
Then, 60 + 70 = 130.
For the 80 percent= 0.8;
==> (170 - 70) × .8 = 80.
Then, 80 + 70 = 150.
