The table represents the recommended exercise intensity for an aerobic program based on the number of visits since beginning the program.
Exercise Intensity
| Number of Visits | Exercise Intensity |
|---|---|
| 1 | 60% |
| 2 | 60% |
| 3 | 60% |
| 4 | ? |
| 5 | ? |
| 6 | ? |
The program suggests maintaining a consistent intensity for the first 3 visits, gradually increasing intensity over the subsequent 3 visits, followed by a decrease in intensity for the next 3 visits, before repeating the pattern. Which of the following options represent the possible intensities for Amber's exercise during the fourth, fifth, and sixth visits? Select three options.
63%, 63%, 63%
66%, 69%, 72%
66%, 62%, 58%
63%, 65%, 67%
67%, 72%, 77%
Answer (2)
The exercise intensity is 60% for the first 3 visits.
The intensity gradually increases for the next 3 visits.
Options 66% , 69% , 72% , 63% , 65% , 67% , and 67% , 72% , 77% represent a gradual increase in intensity.
The possible intensities for visits 4, 5, and 6 are 66% , 69% , 72% , 63% , 65% , 67% , and 67% , 72% , 77% .
Explanation
Understanding the Problem We are given a table that shows the recommended exercise intensity for an aerobic program based on the number of visits. The intensity is 60% for the first 3 visits. Then, the intensity gradually increases for the next 3 visits, and decreases for the subsequent 3 visits. We need to find three options that represent the possible intensities for the fourth, fifth, and sixth visits.
Analyzing the Options The intensity should increase gradually from visit 4 to visit 6. Let's analyze the given options:
Option 1: 63% , 63% , 63% - The intensity is constant, so this is not a gradual increase. Option 2: 66% , 69% , 72% - The intensity increases gradually, so this is a possible option. Option 3: 66% , 62% , 58% - The intensity decreases, so this is not a gradual increase. Option 4: 63% , 65% , 67% - The intensity increases gradually, so this is a possible option. Option 5: 67% , 72% , 77% - The intensity increases gradually, so this is a possible option.
Final Answer Therefore, the three options that represent the possible intensities for Amber's exercise during the fourth, fifth, and sixth visits are 66% , 69% , 72% , 63% , 65% , 67% , and 67% , 72% , 77% .
Examples
Understanding exercise intensity patterns can help athletes and fitness enthusiasts optimize their training routines. For example, by gradually increasing the intensity of workouts over several weeks, athletes can improve their endurance and strength while minimizing the risk of injury. This concept is also applicable in other fields, such as project management, where tasks can be gradually increased in complexity to enhance team skills and productivity.
The valid options for Amber's exercise intensities during visits 4, 5, and 6 are 66%, 69%, 72%; 63%, 65%, 67%; and 67%, 72%, 77%. All three sets show a gradual increase in intensity as required. Therefore, these options reflect the recommended progression in the aerobic program.
