If a woman has a maximum heart rate of 200, what should her target heart rate be for 70% to 80% exertion?

To determine the target heart rate for a woman with a maximum heart rate of 200 beats per minute, we first need to calculate the range for 70% to 80% exertion.

1. Calculate 70% and 80% of the maximum heart rate:

• For 70%: 200 * 0.70 = 140 beats per minute

• For 80%: 200 * 0.80 = 160 beats per minute

2. Determine the target heart rate range:

• The target heart rate for 70% to 80% exertion is therefore from 140 beats per minute to 160 beats per minute.

The correct target heart rate range aligns perfectly with the choice that suggests 140 to 160 beats per minute. This range is crucial for effective cardiovascular training, ensuring that the individual is working within an optimal zone to improve fitness and potentially enhance fat metabolism. It also supports achieving weight control goals effectively through sustained exercise in this exertion level.

The other choices fall outside of this range either by being too low, which would not provide adequate intensity for the desired exertion level, or too high, which could exceed the safe training zone for the
