Question

question 42(multiple choice worth 3 points) (01.06 hc)rae is training for cheerleading, so she starts rollerblading for 45 minutes each day. her heart rate reaches 128 beats per minute, but her target heart rate zone is 140—178 beats per minute. which of the following could she do to get a greater benefit during her 45 - minute activity? skate for a longer time each day skate up the big hill in the park skate at a slower pace each time skate in a flat area with no hills

Explanation:

Increasing the intensity of her roller - blading will raise her heart rate. Skating up a big hill requires more effort and energy, thus increasing heart rate. Skating for a longer time doesn't necessarily increase intensity immediately, skating at a slower pace will lower heart rate, and skating in a flat area is less strenuous than uphill.

Answer:

Skate up the big hill in the park
