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.
The definition of static stretches, as told by <span>www.humankinetics.com, is "</span>a stretch<span> that is held in a challenging but comfortable position for a period of time, typically 15-30 seconds"
With that being said, there is no real way to determine if it is 'safe' or 'unsafe' stretch, but the best option here is option B) </span><span>safe, because it stretches the muscle and joint without causing pain
