Question

question 5 / 5 linda is a 30 year old woman, trying to lose fat. using the training heart rate zone chart, answer the following questions: what is her low and high end training zone linda should be in? a. 95-114 b. 120-140 c. 152-171 d. 90-108

Explanation:

Step1: Calculate Maximum Heart Rate (MHR)

The formula for MHR is $MHR = 220 - age$. For Linda, age is 30, so $MHR = 220 - 30 = 190$.

Step2: Determine Fat - Loss Training Zone Percentage

The typical percentage range for fat - loss training zone is 60% - 70% of MHR.

Step3: Calculate Lower End of Training Zone

Lower end = $0.6\times MHR$. Substituting $MHR = 190$, we get $0.6\times190 = 114$? Wait, no, wait. Wait, maybe the fat - loss zone is 50 - 60%? Wait, let's re - check. Wait, the standard formula for training heart rate: For fat loss, the target heart rate zone is often 60 - 70% of MHR (Maximum Heart Rate). But wait, maybe I made a mistake. Wait, let's recalculate. Wait, $220 - 30 = 190$ (MHR). Then 60% of 190 is $0.6\times190 = 114$, 70% of 190 is $0.7\times190 = 133$. But the options don't have 114 - 133. Wait, maybe the fat - loss zone is 50 - 60%? Let's try 50%: $0.5\times190 = 95$, 60%: $0.6\times190 = 114$. Ah, so 95 - 114, which is option A.

Answer:

A. 95 - 114
