According to the 2018 physical activity guidelines for Americans, adults should aim for at least 150 minutes of moderate-intensity aerobic activity or 75 minutes of vigorous-intensity aerobic activity per week. They should also engage in muscle-strengthening activities that involve all major muscle groups on 2 or more days a week.
Let's check each of Arnold's weekly workout plans:
1. Golfing for 2 hours every Sunday: This would provide 2 hours of moderate-intensity aerobic activity, meeting the guidelines.
2. Biking for 45 minutes a day, 3 days a week: This would provide a total of 135 minutes of moderate-intensity aerobic activity per week, meeting the guidelines.
3. Running for 15 minutes a day, 6 times a week: This would provide a total of 90 minutes of moderate-intensity aerobic activity per week, which falls short of the minimum recommendation.
4. Walking for 30 minutes a day, 5 days a week: This would provide a total of 150 minutes of moderate-intensity aerobic activity per week, meeting the guidelines.
Based on the above analysis, options 1, 2, and 4 meet the minimum recommendations set by the 2018 Physical Activity Guidelines for Americans.
According to the 2018 Physical Activity Guidelines for Americans, adults should aim for at least 150 minutes of moderate-intensity aerobic activity or 75 minutes of vigorous-intensity aerobic activity per week, along with muscle-strengthening activities on 2 or more days.
Let's evaluate each of Arnold's weekly workout plans to see if they meet the minimum recommendations:
- Golfing for 2 hours every Sunday would count as moderate-intensity aerobic activity. Since this is once a week, it falls short of meeting the minimum recommendations.
- Biking for 45 minutes a day, 3 days a week would accumulate a total of 135 minutes of moderate-intensity aerobic activity. This plan falls short of meeting the minimum recommendations as well.
- Running for 15 minutes a day, 6 times a week would accumulate a total of 90 minutes of moderate-intensity aerobic activity. This plan also falls short of meeting the minimum recommendations.
- Walking for 30 minutes a day, 5 days a week would accumulate a total of 150 minutes of moderate-intensity aerobic activity. In addition, walking can be considered a moderate-intensity aerobic activity. This plan meets the minimum recommendations according to the guidelines.
Based on the given options, Arnold's weekly workout plan that meets the minimum recommendations would be walking for 30 minutes a day, 5 days a week.
To determine whether Arnold's weekly workout plans meet the minimum recommendations according to the 2018 Physical Activity Guidelines for Americans, we need to compare the activities to the guidelines. The guidelines suggest that adults should aim for at least 150 minutes of moderate-intensity aerobic activity or 75 minutes of vigorous-intensity aerobic activity each week, along with muscle-strengthening activities on two or more days.
Let's analyze each of Arnold's workout plans:
1. Golfing for 2 hours every Sunday: In this case, Arnold is engaging in moderate-intensity aerobic activity for 2 hours. Since this activity is only performed once a week, it would not meet the guidelines' recommendations for the minimum weekly amount of activity.
2. Biking for 45 minutes a day, 3 days a week: Here, Arnold is engaging in moderate-intensity aerobic activity for 45 minutes on 3 days a week. Multiply 45 minutes by 3 days, and it totals to 135 minutes per week. Since this is less than the recommended 150 minutes per week, it falls short of the guidelines.
3. Running for 15 minutes a day, 6 times a week: By running for 15 minutes on 6 days a week, Arnold is engaging in moderate-intensity aerobic activity for a total of 90 minutes per week. Again, this falls short of the recommended 150 minutes per week.
4. Walking for 30 minutes a day, 5 days a week: On this plan, Arnold is engaging in moderate-intensity aerobic activity for 30 minutes on 5 days a week. Multiply 30 minutes by 5 days, and it totals 150 minutes per week, meeting the minimum recommendations provided by the guidelines.
Therefore, the only workout plan that meets the minimum recommendations according to the guidelines is Arnold's plan of walking for 30 minutes a day, 5 days a week.
