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

Skate Up The Big Hill In The Park.

Explanation:

Rae wants to increase her heart rate, as this will improve her fitness and allow her to be a much better cheerleader.

Those with good fitness do heavier exercise with less effort and thus the heart rate increases more slowly, progressively.

Based on this, we can say that in order to reach his goal, Rae must find a physical activity that requires a large amount of physical effort that is gradual. Among the options given, the one that best fits this concept is "skate the big hill in the park". Skateboarding the large hill in the park will give Rae a great physical effort, it will stimulate the heart, which will need to increase the heart rate, making the heart beat faster because it will need to more irrigate the body with blood.
