Which information is given by a target heart rate? (a) how strong one is (b) how hard one should be working (c) how flexible one is (d) how long one should exercise

Target heart rate provides information about how hard one should be working.

Explanation:

It helps to pace the exercise and balance the activity level. It is the range of numbers or percentage which tells us how hard or fast the heart should be beating when exercising.

Target heart rate corresponds with 50%-85% of the maximum heart rate at 100% which is the highest rate reached with maximum physical exertion. For a normal person aged 50 years, whose maximum heart rate is 170 bpm, the target heart rate would range from 85-145 bpm.
